3D printer
(AIKTC, 2017-05) Shaikh, Mohd. Adil (14DEE01); Chhapra, Abdur (13EE13); Shaikh, Junaid (14DEE15); Khan, Nehal (14DEE02)
The inspiration for this project comes from the fact that 3D printer are really innovative and revolutionary idea but along with that they are very costly, one cannot afford the 3D printer just for fun or to use at home just to create ideas into reality. This high cost limits the imagination of the ordinary people. The high quality 3D printers comes at a range of 65000-140000 rupees. It all starts with imagination of the object we want to create. One can create a affordable 3D printer by using equipment in their surrounding or probably at home. The technology of 3D printing can be used to create imagination into reality, parts of the machinery of equipment which are not available in the market, prototypes of new ideas and most importantly for fun.

(AIKTC, 2017-05) Bodhle, Gulrez; Shaikh, Aslam (12EE3); Ali, Mohd (13EE32); Kadri, Uzma (14DEE13)
Track circuit is the fundamental method of train detection. The first track circuit, based on a DC technology, has been invented at the end of nineteenth. Over the years, the continuous technological development has enabled to realize track circuits in an increasingly performing way by using AC technology and modulations, but the basic principle for train detection is still the same. An alternative approach is the Axle Counter system, which uses a “check-in/check-out” logic. By comparing the result for the axles counted in a block section with the result for those counted out, it is possible to know the status of the track section (free or occupied).

(AIKTC, 2019-05) Sayed, Kaleem; Khan, Safwan Shakil Ahmed (15EE21); Chilwan, Farhan Abdul Majid (15EE07); Sharma, Manishkumar (15EE46); Ulde, Abrar Aslam (15EE51)
At present scenario, renewable energy sources become an alternative source of energy for future energy demand and to mitigate environment pollution problems. Grid connected renewable energy source like wind energy system uses power electronics converters as an interfacing device between wind energy system and utility grid. These converters are commonly based on a voltage source inverter (VSI) connected to the supply network, operated to achieve objectives such as power flow regulation with unity power factor operation. However, intermittent nature of wind energy must be controlled to meet the grid requirements. The grid requirements include independent control of active & reactive power, improved power quality, grid synchronization and Good transient response during fault conditions etc. Usually voltage oriented control (VOC) of grid side converter in the synchronous reference frame was universally adapted for independent control of active and reactive power of the grid. However, the dynamic response during abnormal condition of grid is sluggish and poor power quality. In order to design controller for robust performance and to know the control characteristics, VSI needs to be accurately modelled. This project has taken an attempt to derive the small signal model of a single phase inverter in isolated mode and its performance with different controllers. Further, the work is extended to modelling of three phase grid connected VSI and its relevant transfer functions have been deduced from the model so as to analyse the system performance for designing a controller through well known bode plots. The studied system is modelled and simulated in the MATLAB-Simulink environment..
Active power and frequency analysis of smart grid using simulink
(AIKTC, 2016-05) Farade, Rizwan; Sayyed, Mohd. Ahmed (12EE04); Kadam, Amol (12EE17); Mishra, Sumeetkumar (12EE30); Utekar, Omkar (12EE63)
In this project, a Smart Grid has been designed by MATLAB/SIMULINK approach for synchronization of Thermal and Wind power plant and for analysis of Active-Reactive power and grid frequency. Analysis of Active power and frequency gives the exact idea to know the range of maximum permissible loads that can be connected to their relevant bus bars. Reactive power flow between a wind turbine system and the grid is an important issue especially when the wind turbine is connected to a grid because Wind turbine power production depends on wind speed. The output power is not constant at all as wind speed changes all times. Output Voltage and frequency of these power plants must be same to avoid circulating current in existing power system network in the synchronization process. The maximum and minimum frequency deviation calculated for this smart power system network explains about the permissible range of active and inductive load applied at different load bus, from which stable working condition of the system has been deduced in order to satisfy the frequency deviation of + 3%. The Smart Grid, regarded as the next generation power grid, uses two-way flow of electricity and information to create a widely distributed automated energy delivery network.
Analysis and Implementation of H-Bridge Multilevel Inverter
(AIKTC, 2015-05) Tiwari, Vivek; Shaikh, Mohammed Sadique; Shaikh, Imran Jainuddin; Shaikh, Ghulam; Shaikh, Arshad; Ziyaul, Mujeebul
ABSTRACT The power electronics device which converts DC power to AC power at required output voltage and frequency level is known as inverter. The voltage source inverters produce an output voltage or a current with levels either 0 or positive or negativeVdc. They are known as two-level inverters. Multilevel inverter is to synthesize a near sinusoidal voltage from several levels of dc voltages. Multilevel inverter has advantage like minimum harmonic distortion. Multi-level inverters are emerging as the new breed of power converter options for high power applications. They typically synthesize the stair –case voltage waveform (from several dc sources) which has reduced harmonic content. In this project work, voltage THD analysis of H-bridge multilevel inverter and hardware model of Three-level single phase cascade H-Bridge inverter has been developed using MOSFETS/IGBTS. Gating signals for these MOSFETS/IGBTS have been generated by designing comparators. In order to maintain the different voltage levels at appropriate intervals, the conduction time intervals of MOSFETS/IGBTS have been maintained by controlling the pulse width of gating pulses ( by varying the reference signals magnitude of the comparator ). The results of hardware are compared with simulation results. Simulation models (designed in SIMULINK) have been developed up to five levels and THD in all the cases have been identified.

There have been a considerable number of nuclear reactor concepts proposed over the thirty years of applied nuclear power. A selected number of these have been developed to the extent that one or more plants have been built. Today, only three of these concepts are considered commercially viable. Two of these concepts are based on the use of uranium enriched in the isotope U-235 with light (or ordinary) water employed for cooling and neutron moderation. Of these two concepts, one is the pressurized water reactor or PWR developed by Westinghouse. The other is the boiling water reactor or BWR developed by General Electric. The third concept is based on the use of natural uranium with heavy-water (water enriched in the deuterium isotope) for cooling and moderation. This reactor concept has been principally developed and applied by Atomic Energy of Canada Limited.
Analysis of induction motor by using cascaded multilevel inverter
(AIKTC, 2016-05) Tiwari, Vivek; Mourya, Satishkumar (12EE35); Chaudhary, Faiyaz (13EE72); Khan, Haidar (13EE73); Dahatonde, Akshay (12EE11)
Multilevel inverters had gain popularity over the years in industrial applications such as motor drives, static VAR compensators and renewable energy system. Multilevel inverters have received this attention as it promises less disturbance and possibility to function at lower switching frequency than traditional two level inverters. Out of many level inverters topologies proposed, cascaded multilevel inverters features a high modularity degree because each inverter can be seen as a module with similar circuit topology, control structure and modulation. With large numbers of advantages CMI has one major limitations of voltage unbalance across the dc capacitor. This thesis explores basis structure and operating principles of CMI. Common modulation techniques are summarized. This thesis also presents the total harmonics distortion (THD) analysis of seven level CMI with phase shifted (PS) sinusoidal pulse width modulation (SPWM) and level shifted (LS) SPWM techniques such as phase disposition (PD), phase opposition disposition (POD), and alternate phase opposition disposition (APOD). The harmonic spectrum for PS and LS SPWM techniques are compared. Module capacitor voltage balancing algorithm such as sorting strategy is proposed for CMI.

(AIKTC, 2019-05) Syed, Kaleem; Khan, Mohammed Saif(15EE19); Yadav, Avdheshkumar(15EE52); Shaikh, Shafiqurrahman(15EE45); Ansari, Rabi(15EE03)
The need for renewable energy sources is on the rise because of the acute energy crisis in the world today. India plans to produce 20 Gigawatts Solar power by the year 2020, whereas we have only realized less than half a Gigawatt of our potential as of March 2010. Solar energy is a vital untapped resource in a tropical country like ours. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. In this thesis, we examine a schematic to extract maximum obtainable solar power from a PV module and use the energy for a DC application. This project investigates in detail the concept of Maximum Power Point Tracking (MPPT) which significantly increases the efficiency of the solar photovoltaic system.

Solar System is now widely used for green energy generation. However there arises a problem in voltage levels which affects the system stability. As the solar cell generates fewer amounts of charges we have to use a controller to maximize the efficiency. In this project Inverter Circuit is used. The results are taken and a display panel interfacing with Arduino. This system protects the battery from over charging and deep discharging to increase battery life.

Till last decades, a million miles of cables are threaded in the air across the country. But currently it is laid in the underground, which is larger to an earlier method. Because, underground cables are not affected by any adverse weather condition like pollution, heavy rainfall, snow and storm, etc. But, when any problem occurs in cable. it is very difficult to find the exact locati()n of the fault due to not knowing the exact location of the cable. Day by day, the world is becoming digitized so the project is proposed to find the location of fault in digital way. When the fault occurs, the process of repairing related to that pa1ticular cable is very difficult. The fault of the cable mainly occurs due to many reasons. They are inconsistent, any defect, weakness of the cable, insulation failure and breaking of the conductor. To overcome this problem, here is a project namely underground cable fault distance locator, used to find the location of the fault for underground cable. Before attempting to find undergrouDd cable faults on direct bidden cable, it is essential to know where the cable is situated and what direction it takes. Since it is extremely difficult to find a cable fault without knowing where the cable is. it makes sense to master cable locating and tracking before start the fault locating process .The success of fault tracking and locating of an underground cable is mainly depends on the skill, knowledge and experience of that person. Although tracing of the cable can be an intricate job, it will very likely become even more complex as more underground plant is installed. It is just as important to understand how the equipment works.

In today's modern world where the demand of the consumers for electricity requirement is going on day by day. To achieve this ELECTRICAL POWER SYSTEM is the heart which continuously pumps the electricity from one end to other end by means of transmission and distribution system. During this process if any of the phases of healthy phases runs out then the production process at that end gets hindered which leads to economic and productivity losses. In our project we have shown by means of electrical and electronic components how auto selection can be done. We will be showing it by means of various graphs indicating various electrical parameters. We hope that our project would be successful and it would be adopted as well in the power system component

This project is mainly proposed for reducing the power loss in industries by using power factor compensation through a number of shunt capacitors. Power factor is defined as the ratio of real power to apparent power. So, the increase in reactive power (real power) increases the apparent power, so the power factor also decreases. By having a low power factor , the industry needs more energy to meet its demand, so the efficiency decreases. In this system , we proposed the time lag between zero voltage pulse and zero current pulse delay generated by suitable op-amp circuits in comparator mode and fed into two interrupt pins in the microcontroller. The microcontroller displays the power loss due to inductive load on the LCD. This process is continuously actuated until the power loss would be zero by using relays which are used to bring the shunt capacitors into the load circuit. an 8-bit microcontroller is used in this project which belongs to the 8051 family.

The project deals with use of alternative energy resource for power generation which can be used to supply power in domestic application. Solar energy is a very large, inexhaustible source of energy and Green Energy System. Solar energy has a major advantage for no impure outlets but problem associated with solar is less efficiency and high cost. The power from the sun intercepted by the earth is approximately 1.8x1011MW, which is many thousand times larger than the present consumption rate on the earth of all commercial energy sources. Solar tracking system can be used as a power generating method from sunlight. This method of power generation is simple and is taken from natural resource. This needs only maximum sunlight to generate power. This project presents for power generation and sensor based solar tracking system to utilize the maximum solar energy through solar panel by setting the equipment to get maximum sunlight automatically in real time. This proposed system is tracking for maximum intensity of light. When there is decrease in intensity of light, this system automatically changes its direction to get maximum intensity of light. The proposed method is to design an electronic circuit to sense the intensity of light and control the DC motor driver for the panel movement, and construct a Buck- Boost converter for to step up and step-down the voltage, and store the maximum utilized output voltage in Lead-Acid Battery.

Our Power transformer is one of the most critical components for electrical network in power plants. This means that dependability has a big role. At the moment end users allocate resources to power transformer maintenance. Resources for on-line condition monitoring on the other hand are not very significant. Reason for this is that transformers are reliable and long life components. However, failure costs might be very significant and online monitoring is justified from that point of view.This Project focuses on power transformer online condition monitoring. The goal is to find cost-effective and integrated solution which provides good-enough transformer monitoring. The subject has been studied quite a lot which tells about increasing interest towards the subject and might indicate possible markets for transformer monitoring services. In the beginning research will focus on describing maintenance and condition monitoring related terms. Also goals are defined for different stakeholders applying the Delphi method. The middle part of the work focus on power transformer structure, fault statistics, condition monitoring methods and measurement devices. Also possibilities of condition monitoring are covered.Research results are divided into two different categories. First part of the results will be related to requirements defined for power transformer condition monitoring. Results include requirements for three different ranges of transformer monitoring. Second part of the results contains a specification for pilot project to test power transformer condition monitoring methods and devices

As we know that power system load is increasing day by day as the industrial and commercial load are increasing . In modern power system most of the load is inductive load to compensate this inductive load capacitive load is must require . Inductive load is consume reactive power in the system which affect generation of plant the main application of apfc panel is it has automatic capacitor which connected according to requirement of reactive power. Control Panel as the name implies, are used to provide proper control of operations of any electrical equipment’s. These are also used to protect the electrical. Equipment’s from being damaged due to various faults like short circuit, overload and Earth leakage etc. Electrical control panels and capacitor bank are important system or equipment in electrical industries also in other industries so we going to do a case study on that. They are found in factories to monitor and control machines or production lines and in places such as nuclear power plants, ships, and aircraft and mainframe computers. protection is mainly provided through panels. A panel is used for controlling and giving the indication about the faults in system or any machines etc. It also disconnect the system from supply of there is a fault. Different panels are used for different location, scheme of protection, according to consumer demand etc. In which some of the panels are RTCC, MBox, TJB, etc. Here we deal with different methods or steps that are involved in dedication of our group members. Capacitor banks are applied in power systems to provide reactive power. The reactive power results in lower current in lines upstream of the bank improving system voltage and power factor and reducing line losses. Capacitor banks can be configured as filters for harmonic reduction. The protection systems for capacitor banks include fuses, surge arresters, and protective relays. This paper focuses on protective relaying philosophies of grounded and ungrounded Y-connected shunt capacitor banks, which are commonly applied on industrial and utility power systems.

The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters, human errors while noting down the meter reading, and errors while processing the paid bills and the due bills. The home appliances which consume more power causes an increase in the payment of excessive bills. The development of a fully Automated Energy Meter which is having capabilities like remote monitoring and controlling of energy meter will lead to transparency in the energy meter reading and billing system. Automatic Meter Reading (AMR) system give the information of meter reading, power cut, total load used, power disconnect and tempering on request or regularly in particular interval through SMS. This information is being sent and received by customer with the help of Global System for Mobile (GSM) communication network.
