一种分布式静止串联补偿器控制系统及其控制方法
摘要：
本发明涉及一种分布式静止串联补偿器控制系统及其控制方法，该控制方法包括：根据电力系统调度指令以及线路运行状态监测结果，选择线路中分布式静止串联补偿器的补偿模式；在选择的补偿模式下，计算线路中分布式静止串联补偿器需要输出的总补偿电压，进而确定该条线路中需要投入的分布式静止串联补偿器的数目以使每个分布式静止串联补偿器的输出电压不低于电压阈值。本发明根据电力系统调度指令确定线路中分布式静止串联补偿器的补偿模式，在确定的补偿模式下，确定需要投入的分布式静止串联补偿器的数目，以使每个投入的分布式静止串联补偿器的输出电压大于电压阈值，有效提高了分布式静止串联补偿器的运行效率。
摘要（英）：

The invention relates to a distributed static series compensator control system and control method thereof. The control method comprises the steps of selecting a compensation mode of each distributedstatic series compensator in a circuit according to an electric power system dispatching instrument and a circuit operating state monitoring result; and in the selected compensation mode, calculatingthe total compensation voltage needed to be output by the distributed static series compensator in the circuit, and then further determining the number of the distributed static series compensators needed to be input in the circuit so as to enable the output voltage of each distributed static series compensator to be not lower than a voltage threshold value. According to the control method, the compensation mode of each distributed static series compensator in the circuit is determined according to the electric power system dispatching instrument; in the determined compensation mode, the number of the distributed static series compensators needed to be input is determined, so that the output voltage of each distributed static series compensator is greater than the voltage threshold value;and therefore, the operating efficiency of each distributed static series compensator is improved effectively.
