ABSTRACT

In this paper, an electronic voltage and frequency (EVFC) controller has been implemented and simulated in MATLAB/SIMULINK Simpower System Blockset to regulate voltage and frequency of a IAG feeding three-phase balanced and unbalanced linear and non-linear consumer load for constant power applications such as uncontrolled turbine in Pico hydro power generation (<10kW). The EVFC consists of a diode bridge rectifier, IGBT based chopper switch, dc filtering capacitor, PI controller and a resistive Dump load. The steady state and transient behaviour of IAG-EVFC system is examined and studied under different operating conditions to demonstrate the capabilities and effectiveness of electronic voltage and frequency controller (EVFC). The switching ON and OFF like operating condition of balanced and unbalanced load of consumer are obtained by adding circuit breakers in the Simulink model of the system under study
