Kirby & Hirst indicate three reasons behind the need for voltage control: 1. the power network equipment is designed for a narrow voltage range, so is the power consuming equipment on the customer side. Operation outside of this range will cause the equipment to fail; 2. reactive power causes heating in the generators and the transmission lines, thermal limits will require restricting the production and the flow of real (active) power; WebSTATCOM or Static Synchronous Compensator is a power electronic device using force commutated devices like IGBT, GTO etc. to control the reactive power flow through a power network and thereby increasing the stability of power network. STATCOM is a shunt FACTS controller i.e. it is connected in shunt with the line.
