摘要/Abstract

摘要： 适用于高压直流输电系统的±100 MVar高压静止同步发生器(Static Synchronous Compensator, STATCOM)装置,对可靠性要求较高,控制系统设计需要较高的响应速度来应对金属性接地故障等极限工况。电流直接控制方式较适用于这种情况。研究了直接电流方式下的准谐振控制器,并讨论其参数整定方法。通过数学推导过程说明了关键参数K_p和K_r的计算方法。针对南方电网云南-广西富宁换流站的高压STATCOM参数进行了计算和RTDS仿真。仿真结果表明,该控制方法能够满足10 ms动态响应时间要求,并具备单相金属性接地故障穿越能力,具有一定的工程应用价值。

Abstract: ±100 MVar high voltage static synchronous compensator (STATCOM) device is used for high voltage DC transmission which needs higher reliability. Faster response for its control system to deal with metal ground fault and other situations is required. Direct Current Control (DCC) can be used for these situations. Quasi- Proportional Resonant (quasi-PR) controller under DCC was studied and its parameters settings were discussed. The calculation methods of key parameters such as K_p and K_r were explained by mathematical deduction process. The STATCOM under higher voltage in Yunnan-Guangxi Funing transaction station was taken as an example for the calculation of its parameters and RTDS simulation. Simulation results indicate that this control method satisfies the needs of less than 10ms response time and has single-phase metal ground fault crossing capability. It has certain practical and engineering value.

Key words: parameters setting, direct current control (DCC), independent phase control (IPC), quasi-proportional resonant control (quasi-PR), RTDS experiment, STATCOM under higher voltage
