摘要
Abstract
Because the cascade STATCOM DC side capacitor is separate, so keeping the voltage of these capacitor balanced is very important. In the energy point of view, the voltage change process of the cascade STATCOM DC side capacitor was studied, and the mechanism of the unbalanced capacitor change was explained. Otherwise, the gate pulse rotated transposition was studied, which could restrain the unbalance of the capacitor voltage. But when the wastage of the STATCOM unit was not the same, the gate pulse rotated transposition could not restrain the unbalance of the capacitor voltage. In order to avoid this problem, the gate pulse sort transposition was put forward. Especially, when the wastage of the STATCOM unit was not the same, this method could also keep the capacitor voltage balanced. The result of the simulation shows that: gate pulse sort transposition can keep the capacitor voltage balanced, when the wastage of the STATCOM unit is not the same.关键词
