The Voltage Balance Control Strategy of the Sub-Module Capacitor in STATCOM

Abstract:

The capacitor voltage balance of the sub-module is the necessary condition for normal operation of the STATCOM. In this paper, the topology and mathematical model of the STATCOM are introduced briefly, the instantaneous power characteristic and capacitor voltage balance principle are studied in detailed, and the balance control algorithm for real project is put forward, in this algorithm, the modified reference wave is got by delay the phase modulation wave by 90°, rather than calculate the sine value of the PLL phase. So the algorithm in this paper can realize in sub-module in real project, the simulation result and real project validated its efficient.
