    Frictionless braking system of wind turbine
    (AIKTC, 2016-05) Patel, Iftekar
    Frictionless braking of wind turbine is a robust technique which is used in order to provide effective braking for wind turbines which is a non-conventional source. It provides safety against failures like over-speeding of wind turbines. It is advantageous because it provides suitable braking by frictionless brake. Most of the braking systems utilize friction forces to transform the kinetic energy of a moving body into heat that is dissipated by the braking pads. The over use of friction-type braking systems causes the temperature of the braking pads to rise, reducing the effectiveness of the system. There relative motion between the magnet and the metal (or alloy) conductor produces an eddy current that induces a reverse magnetic field and results in deceleration. This braking is provided by generation of eddy current phenomena. This eddy current is produce in the stationary plate which opposes the rotary motion of rotating plate and finally rotating plate is being stopped. The many of advantages it having non-contact, no wear, no electric actuation ,light in weight so it can be very useful for wind turbine. Without using friction, an eddy-current braking system transforms the kinetic energy of the moving body into heat energy that is dissipated through the eddy current in the conductor. This concept is used for the braking of wind turbine to avoid the failure of wind turbine.

    (IOSR Journal of Engineering, 2019) Patel, Iftekar; Khan, Sarfaraz (16DEE60); Mansuri, Madni (16DEE64); Khan, Qais (16DEE61); Haji, Altamas (16DEE57)
    The concept of High Altitude Wind Power ( HAWP ) is to supply clean energy at low cost and high capacity factor than the Conventional Wind Power ( CWP ) system. This is one of the new technologies deployed for harvesting high altitude wind power using airborne wind turbine -cum electric generator supported by light gas filled blimp/aerostat has been proposed in the project. An airborne wind turbine at high altitude extracts kinetic energy from the high speed streamlined wind using buoyancy provided by the blimp. Using a suitable power electronic converter (PEC), harvested electrical power is transmitted to the ground by using a tether. A Blimp is tethered tothe ground and provides mechanical strength to hold the blimp and the same tether consisting of an electrical conductor is used for transmitting the generated power. In addition, a comparative study between conventional wind energy harvesting system and high altitude wind energy harvesting system shows that high altitude wind power is better in terms of capacity factor, Cost of Electricity (COE), ease of construction and power density than conventional wind power generating system.

    High Altitude Wind Turbine
    (AIKTC, 2019-05) Patel, Iftekar; Khan, Mohd.Sarfaraz (16DEE60); Mansuri, Mohd.Madni (16DEE64); Khan, Qais (6DEE61); Haji, Altamas (16DEE57)
    The concept of High Altitude Wind Power (HAWP) is to supply a clean energy at low cost and high capacity factor than the Conventional Wind Power (CWP) system. This is one of the new technologies deployed for harvesting high altitude wind power using air-borne wind turbine-cum electric generator supported by light gas filled blimp/aerostat has been proposed in the project. An air-borne wind turbine at high altitude extracts kinetic energy from high speed streamlined wind using buoyancy provided by the blimp. Using a suitable power electronic converter (PEC), harvested electrical power is transmitted to the ground by using a tether. Blimp is tethered to the ground and provides mechanical strength to hold the blimp and the same tether consisting of electrical conductors is used for transmitting the generated electrical power. The project out lines major components used for harvesting high altitude wind power.Transmission of the electrical power at medium voltage DC reduces the transmission loss and volume of the conducting cable. The optimal transmission voltage level that gives minimum weight of the tether has been calculated for a given power level. The proposed HAWP system requires high power density PEC, which converts low voltage AC to medium voltage DC in an air borne unit and a ground based PEC that transforms medium voltage DC to distribution level grid voltage. Further, it also proposes the ground based grid-side PEC for distributed grid interface. In addition, comparative study between conventional wind energy harvesting system and high altitude wind energy harvesting system shows that high Altitude wind power is better in terms of capacity factor, Cost of Electricity (COE), ease of construction, and power density than conventional wind power generating system.

    Electrical power system is a technical wonder. Electricity and its accessibility are the greatest engineering achievement of the 20th century. A modern society cannot exist without electricity. Generation, transmission lines and distribution system are the main components of power system. Today's world most of the systems are operate on automation. Because of that the automotive system is most efficient. Automation means use of Programmable Logic controller (PLC) & Supervisory control and data acquisition (SCADA) instead of electromechanical devices. Substation (Transformer) automation using PLC means controlling & monitoring electrical parameter (like Voltage, Current, temperature, oil level) and controlling if any fault occurs (like open circuit, short circuit, overvoltage, oil level, &temperature, etc.) in substation transformer. The fault free operation of transformer gives more impact on economic and safety in power supply to utilities and industrial and domestic consumers. A sudden breakdown/fault in a power transformer will affect unexpected production interruption, down time of equipment’s in industries and the repair/replacement of transformer; it may lead to huge investment and expenses. The insulating oil in a transformer can tell a lot about the actual state of transformer and its longevity. Main concept of our project is to control and monitor substation (transformer) using PLC. Here PLC is a medium between electrical system to take inputs and outputs bits. We can say that the system is one of the most cost effective solutions for improving reliability, increasing utilization, increasing efficiency and costs saving. PLC on the other hand is like the brain of the system, it is possible to control and operate the power system remotely. Task like oil level control, short circuit, open circuit etc.

    Home automation is designed to prevent an actual confrontation between a returning occupant and an intruder. In the market, we found out many systems that can be use to protect the property. However if a member of the family was away, we wanted a system that would inform the member if the house has being broken into. This was ultimate safety that one looks for in a home security system. We can also add features such as lpg gas leakage, fire breakdowns or even water tank overflow. Chapter 2 deals with the history of home automation along a brief description of Hardware & Software. Chapter 3 deals with the basics of GSM System. It gives the details of the adopted methodology which includes Block diagram, Circuit diagram, Hardware & Software used. Chapter 4 deals with Analysis, Experimentation & Results. It includes descriptions of various ICs used, PCB layout & Challenges faced during our project. Chapter 5 deals with the future scope and conclusion. In order to make the system ‘smart’, we have made the mobile phone almost a universal remote controller, where in the user can control various devices at his home just through the SMS. We have even solved the i/o port limitations by expanding the ports using latches and buffers so that more sensors can be interfaced in future.

    PLC & SCADA based substation automation
    (AIKTC, 2015-05) Patel, Iftekar; Chitapure, Sirajuddin (12EE75); Ansari, Sameer (12EE76); Shaikh, Adnan (12EE82); Kondkari, Faizan Ahmed (12EE85)
    lectrical power systems are a technical wonder. Electricity and its accessibility are the greatest engineering achievements of the 20th century. A modern society cannot exist without electricity. Generating stations, transmission lines and distribution systems are the main components of power system. Smaller power systems (called regional grids) are interconnected to form a larger network called national grid, in which power is exchanged between different areas depending upon surplus and deficiency. This requires a knowledge of load flows, which is impossible without meticulous planning and monitoring .Also, the system needs to operate in such a way that the losses and in turn the cost of production are minimum. The major factors that influence the operation of a power system are the changes in load and stability. As is easily understood from the different load curves and load duration curve, the connected load, load varies widely throughout the day. These changes have an impact on the stability of power system. As a severe change in a short span can even lead to loss of synchronism. Stability is also affected by the occurrence of faults, Faults need to be intercepted at an easily stage and corrective measures like isolating the faulty line must be taken. As the power consumption increases globally, unprecedented challenges are being faced, which require modern, sophisticated methods to counter them. This calls for the use of automation in the power system. The Supervisory Control and Data Acquisition (SCADA) and Programmable Logic Controllers (PLC) are an answer to this. SCADA refers to a system that enables on electricity utility to remotely monitor, co-ordinate, control and operate transmission and distribution components, equipment and real-time mode from a remote location with acquisition at date for analysis and planning from one control location. PLC on the other hand is like the brain of the system with the joint operation of the SCADA and the PLC, it is possible to control and operate the power system remotely. Task like Opening of circuit breakers, changing transformer taps and managing the load demand can be carried out efficiently. This type of an automatic network can manage load, maintain quality, detect theft of electricity and tempering of meters. It gives the operator an overall view of the entire network. Also, flow of power can be closely scrutinized and Pilferage points can be located. Human errors leading to tripping can be eliminated. This directly increases the reliability and lowers the operating cost. In short our project is an integration of network monitoring functions with geographical mapping, fault location, load management and intelligent metering.

    Smart grid
    (AIKTC, 2020-05) Patel, Iftekar; Ansari, Ahsan Mohammed Murtaza (17DEE37); Ansari, Faisal Ahmed Firoz Akhtar (17DEE38); Ram, Jitendra Rajkumar (17DEE61); Shaikh, Mohammed Ahsan Abdul Salam (17DEE66)
    The smart grid delivers electricity from producers to consumers using two-way digital technology, and allows control of appliances in the consumer’s houses and of machines in factories to save energy, while reducing costs and increasing reliability and transparency. Such a modern electricity network is promoted by many governments as a way of handling energy independence, global warming and security of supply A smart grid includes an intelligent monitoring system that keeps track of all the electricity that flows in the system. It could incorporate the use of super-conducting transmission lines to reduce losses, as well as the ability to integrate electricity from alternative sources such as solar and wind. When electricity cost is low, the smart grid can offer the customer to run intensive consumption household appliances, such as washing machines, or processes in plants that operate at flexible hours. On the other hand, smart grid at peak hours can, in coordination with the client, turn off selected appliances and machines to reduce demand.
