| 摘要: |
| 研究了静止同步补偿器（STATCOM）参与自动电压控制（AVC）调节的控制策略。提出了基于系统电压变化、电网故障判断等信息的一系列STATCOM控制模式及不同控制模式的逻辑判断标准。设计实现了STATCOM与站内固定电容器组相互协调的一级电压控制策略及STATCOM与远方控制信号相互协调的二级电压控制策略。在一级电压控制策略中，对于不同控制模式的STATCOM，通过使固定电容器组的静态无功功率置换出STATCOM的动态无功功率，从而增大了系统的动态无功功率储备。在二级电压控制策略中，通过STATCOM对远方控制信号的响应，从而实现了STATCOM对非接入点母线电压的支撑。IEEE 39节点系统模型上的仿真结果验证了上述控制策略的合理性。 |

| Abstract: |
| The control strategies of STATCOM participating in the AVC（Automatic Voltage Control） are researched and a series of STATCOM control modes with corresponding logic judgment standards based on the information of system voltage variation and grid fault diagnosis are put forward. The first-level coordinative voltage control of STATCOM and in-station fixed capacitors and the second-level coordinative voltage control of STATCOM and remote control signal are designed and implemented. The strategy of first-level control replaces the dynamic reactive power of STATCOM in different control modes with the static reactive power of fixed capacitors to increase the dynamic reactive power reserve of system，while the strategy of second-level control supports the bus bar voltage of non-accessing points by the response of STATCOM to remote control signal. The rationality of the proposed control strategies is verified by the simulative results of IEEE 39-bus system model. |
