摘要

配电静止同步补偿器（DSTATCOM）通过向公共连接点注入无功功率可以调节公共连接点的电压

使之满足电压合格的要求、笔者首先根据DSTATCOM系统中的瞬时功率平衡理论推导出了DSTATCOM用于控制电压时的直接电压控制策略。在该控制策略中

无需电流检测电路

跟传统的串级控制相比较具有控制简单、响应速度快等优点。然后针对电网电压不平衡对DSTATCOM的影响

在基于瞬时功率平衡的直接电压控制的基础上

引入了负序电压的前馈控制策略

避免了DSTATCOM因电网电压不平衡造成的过流而退出运行。理论分析和仿真结果证明了笔者所提控制方法的正确性和有效性

该控制策略对DSTATCOM装置的实际开发有很好的借鉴作用。

Abstract

The DSTATCOM regulates the voltage of the common coupling point（PCC）by injecting reactive power to it for meeting the requirement of voltage.Based on the balance of the instantaneous power of the DSTATCOM system

a direct output voltage control strategy for voltage control is proposed without current detection circuit.Compared with the cascade control strategy

the proposed one has the merits of simple structure and fast response time.On the basis of direct voltage control

the negative sequence voltage feedforward control is introduced to overcome the overcurrent of DSTATOCM when the main voltage is unbalanced.The effectivity and validity of the present control strategy is verified by the theoretic analysis and digital simulation.The control strategy presented in this paper can be used in development of DSTATOCM.
