Improvement of power quality of a distribution supply system is a challenging problem and it may not be economic to simply upgrade the network. FACTS controller like STATCOM (STATics synchronous COMpensator) offers an attractive alternative, with their potential to provide both steady state and transient voltage compensation for a limited capital investment. However, operation of these systems with weak networks needs careful attention to achieve a stable and fast response under all supply conditions. This paper proposes a control strategy of a STATCOM to improve power factor and voltage regulation at a distribution supply system which is more robust and works well under all system conditions and improves power quality directly. Simulation results are presented to verify the stability and validity of this control strategy across a range of operating conditions. The operation of the STATCOM with distribution supply system makes the rural consumers healthy and wealthy.
