基于三电平直接瞬时电流分相控制的DSTATCOM装置及其应用

基于三电平直接瞬时电流分相控制的DSTATCOM 装置及其应用:一般的δ 角控制方式响应速度慢且易发生过流，不能满足配电静止同步补偿器(DSTATCOM)的运行要求。
本文提出了直接瞬时电流分相控制的策略，使得三电平DSTATCOM 的响应速度显著提高，并具有很强的抗扰能力。DSTATCOM 工业样机应用于电弧炉补偿，抑制电压闪变的效果非常明显，同时提高了冶炼效率。
Abstract: General δ-control method responses slowly and suffers overcurrent. Therefore, it does not satisfy the operating requirements of distribution static synchronous compensator (DSTATCOM). In this paper, a novel control strategy
is proposed, named direct instant current control for individual phase, which improves the response of three-level
DSTATCOM significantly and has strong capability of withstanding perturbations. A DSTATCOM has been commissioned
for electric arc furnace compensation. It eliminates majority of voltage flickers and meanwhile increases the steel-producing efficiency.
