VOLTAGE AND FREQUENCY CONTROL OF STANDALONE WIND DRIVEN SELF-EXCITED RELUCTANCE GENERATOR

Abstract

This thesis intended to study the performance of standalone wind-driven self-excited reluctance generator (WDSERG) at different running circumstances of excitation capacitors and loads with studying its suitability for wind energy applications. Two different configurations of compensation (short shunt and long shunt) are proposed and the preferred configuration is selected. A complete dynamic d-q axis model and equivalent circuit of the SERG are developed for each configuration. The complete model was utilized for studying varies cases of wind speed, load current and power factor values to obtain the dynamic behavior of the WDSERG. Furthermore, generator speed and load voltage are controlled by the two configurations of compensation using PI controllers to determine the suitable capacitance values for a WDSERG, that will generate fixed load voltage and frequency value through different cases of wind speed and load current.
