Abstract

The wind generated power always vary irregularly due to its time varying nature and causing stability problems. This weak interconnection of wind generating source to the electrical grid affects the power quality and reliability. Here we have designed static compensator (STATCOM) using Voltage Source Inverter to reduce volta ge sags, swells, transients, harmonics hence enhance power quality of the system. We have used Pulse Width modulation technique to control voltage source converter. The STATCOM is modeled and its performance is simulated and load, source voltages and curre nts waveforms are taken and Total Harmonic Distortion (THD) is calculated by using MATLAB simulation. The development of the grid co - ordination rule and the scheme for improvement in power quality norms as per IEC - standard on the grid has been presented
