Abstract

Power quality means maintaining the voltage, current and power within the rating as per the IEC standards and supplying it back to the consumers without any delay and interruption. But this has become a difficult task for the power industry. To improve power quality many Custom Power Devices (CPD) are used. Dynamic Voltage Restorer (DVR) is a CPD which is used to improve the voltage quality. Hybrid Active Power Filter (HAPF) is used to reduce current harmonics. In this chapter DVR and HAPF are simulated for various conditions. A controller is proposed which gives voltage signals to trigger the switches of an inverter using a Pulse Width Modulation (PWM) scheme. As a result, there is drastic improvement in voltage profile and also reduction in harmonics.
