摘　　要：提出了基于敏感用户的电压暂降设备控制策略。在建立静止同步补偿器(STATCOM)数学模型、分析控制策略的基础上,运用变参数控制法对控制策略进行改进,最后以某典型工业负荷供电为例验证控制策略的有效性。算例结果表明,控制策略能够有效提升电压暂降设备治理效果,抬升负荷侧电压。A control strategy of equipment replying in voltage sag recovery based on sensitive load was proposed. On the basis of establishing the mathematical model of STATCOM and analysis of existing STATCOM control strategy,the control strategy was improved through using the changing parameter control strategy. A typical example of industrial load was used to prove the effectiveness of the control strategy. The results show that the improved control strategy can enhance the governance effect of equipment replying in voltage sag and raise the load voltage.
