INTRODUCTION

OPERATING PRINCIPLE

CONTROLLER MODEL

Provides reactive power compensation to solve problem in Industrial system.

It is connected near the load at the Distribution System.

Promising future for improving system performance.

V i = Output Voltage of the statcom .

Vs = Distribution system voltage.

1.Vi = Vs

2.Vi > Vs
