Abstract :
PCS9580 static reactive power compensation system presents an independent development of fast open-loop control algorithm and closed-loop stable control strategies to provide effective voltage support and reactive power compensation for the power network and load. It can effectively suppress voltage fluctuations, with voltage flicker improvement rate more than 50%. And filters parameters are optimized with good harmonic suppression function, in order to effectively improve the quality of power supply. A complete secondary control and protection strategies is presented here and network configuration solution can effectively achieve the dynamic damping of the power network, transient voltage regulation, and instantaneous strong compensation function.
