    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..

    Case study on manufacture of panel and capacitor bank
    (AIKTC, 2020-05) Sayed, Kaleem; Dalvi, Prasad Satappa (17DEE45); Tandale, Harshada Vijay (17DEE48); Karanjvade, Shubham Ananda (17DEE50)
    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.

    Designing and modelling of photo-voltaic cell
    (AIKTC, 2020-05) Sayed, Kaleem; Chavan, Rohan Raghoji (17DEE44); Parte, Prathamesh Sunil (16EE23); Shaikh, Mohammed Aftab (17DEE65); Parkar, Abid Akhtar (14EE64)
    Our aim is to innovate and integrate renewable energy sources as a new source of energy. We thoughtfully chose the Solar energy as a source to be worked upon. We have hence made use of photo-voltaic cell, modelled and designed it in Matlab Simulation. We have integrated Auto-tuning of PID Controller and Boost Converters. Also we have used Battery Storage Energy system (BESS) to store excess energy and give it back to the load I needed.
