Abstract:The induction motors are predominant in industrial applications. The motor runs on three phase supply and an acceptable temperature maintain the loads at desired conditions. But if any phase goes missing or there is increase in the temperature of the windings it damages the motor. Therefore, this project helps to provide protection to the industrial motors by removing the power to the motor immediately if any of the phases misses out of the three phases, or if the temperature of the motor exceeds the threshold value. Thus, this project is to develop an induction motor protection system for protecting the motor from any damages occurring from single phasing and over temperature conditions.
The objective of this paper is to improve Voltage profile of the system by controlling reactive power using a synchronous vector PI controller. Voltage in a power system is mainly affected by reactive loads and faults. This paper proposes modeling of a STATCOM (STATic+ COMpensator) with a synchronous vector PI controller under a nonlinear load. The prototype has been programmed in MATLAB/SIMULINK environment which has been tested on a standard IEEE 14 bus system. It has been observed that after installing STATCOM the voltages of the buses are found to be within the acceptable limits.
