SIMULATION OF THE HYSTERESIS VOLTAGE CONTROL TECHNIQUE IN THE PV BASED DYNAMIC VOLTAGE RESTORER FOR POWER QUALITY IMPROVEMENT WITH INDUCTION MOTOR DRIVE

摘要

Voltage sag and swell in the average and low electrical energy distribution grid are measured to be the nearly all frequent type of power quality problems base on top of topical power quality study. Their impact on responsive loads is severe. To equipment these situation, convention power equipment are utilize. Dynamic Voltage Restorer (DVR) is modified power equipment to be utilized to improve voltage stability. The future concept is PV cell as the Input to inverter and the presentation of the DVR know how to be implement with squirrel cage Asynchronous motor drive. This paper present the hysteresis voltage control technique base on voltage reference signal, for generation of switch pulse for inverter of dynamic voltage restorer and the future system is design in MATLAB software, results show that the how dynamic voltage restorer is useful for power quality development in distribution system.
