Energy can be transformed from one form to another form and can also be stored. Electrical energy can be generated, distributed and can be stored using batteries. This project describes a method of charging a 12V battery with constant output voltage and variable input voltage using Buck-Boost topology. The variation in duty cycle of MOSFET will provide variation in output voltage. The error in output...
This paper presents the analytical Modeling of Switched Reluctance Motor(SRM) based on the data obtained from Finite Element Analysis(FEA) tool Ansys Maxwell. Once the design of the machine is done in FEA tool then before manufacturing the actual machine it is necessary to test its dynamic performance. Testing of dynamic performance involves the operation of the motor with different control strategy...
This paper presents the performance and comparative analysis of Static Synchronous Compensator (STATCOM) based on 6, 12 and 48-pulse VSC configuration. STATCOM is implemented for regulation of the voltage at the Point of Common Coupling (PCC) bus which has time-variable loads. The dq decoupled current control strategy is used for implementation of STATCOM, where modulation index M and phase angle...
The Static Synchronous Compensator (STATCOM) is one of the most widely used Flexible AC Transmission System (FACTS) device which is based on a voltage source converter with a dc link capacitor. This paper presents the mathematical modelling of STATCOM in dq domain, with the Q-Vdc controller to control the reactive power flow in the system and to maintain the dc voltage at a constant value. The control...
A hardware setup of multiple Flexible AC Transmission systems (FACTS) devices in a Power Systems Laboratory will help to understand the dynamic performance of these devices and can provide a platform to test, implement and compare new control algorithms. This paper describes the development of FACTS Laboratory setup in COEP which can demonstrate the working of different FACTS devices like Static Compensator...
This paper presents Distribution Static Compensator (DSTATCOM) modeled in the MATLAB SIMULINK toolbox for the mitigation of the power quality issues in the distribution system. DSTATCOM is one of the custom power device used in distribution system for power conditioning. DSTATCOM is developed for the compensating reactive power demanded by non-linear and unbalanced load. Also power factor of the source...
Conducting poly(o-anisidine) coatings were obtained on low carbon steel in aqueous oxalic acid solution by using the galvanostatic technique. The coatings were characterised by potential-time relations, UV-VIS absorption spectroscopy, scanning electron microscopy, and X-ray diffraction measurements. The electrochemical performance of coated steel electrodes was evaluated on the basis of galvanostatic...
Z-Source inverters have been proposed as an alternative power conversion concept as they have both voltage buck and boost capabilities. These inverters use a unique impedance network to couple the converter main circuit to the power source, to provide both the voltage buck and boost properties which cannot be achieved with conventional voltage-source and current-source inverters. To understand the...
This paper presents a brief review of Z-source converter. This converter employs a unique impedance network to couple the converter main circuit to the power source thereby overcoming the limitations of the traditional converters and provides a novel power conversion concept. This new converter topology is examined with Unified Power Flow Controller(UPFC) and a simulation study was carried out in...
