Step–less reactive compensator –STATCOM

Static Synchronous Compensator (STATCOM) hasearned its name as it does not have any rotating or moving parts, and yet offers a fast and step-less reactive compensation. It is based on voltage source converter (VSC) technology, which uses low-voltagecells in series to realise a high voltage output

By controlling the output voltage to be either higher or lower, STATCOM will draw a capacitive or inductive current from the system. Also unlike a constant impedance device like a capacitor or inductor whose output current will decrease with voltage, STATCOM can continue to generate its maximum output current even at low system voltages as it is not dependent on passive reactive components.

The main advantages and features of the ZDDQ STATCOM technology include wider operating voltage range, quicker response time and stronger mitigation ability for voltage fluctuation,smaller footprint, eliminating the need for expensive filters, modular solution, and many more.It can compensate both capacitve and inductive power from -1~1 PF maintain.
