中文摘要:
      ±100 Mvar以上的大功率高压链式STATCOM必须进行换流链全功率试验,但是受制于大容量设备的要求,此类试验非常困难。传统的全功率试验是采用2套高压链式STATCOM装置对拖,成本很高,对场地和接入电网的要求严苛。通过全直流供电的方式,采用充电电源和补能电源构建了一种新型的试验平台,可以有效降低对接入电网的要求。在第1条换流链上采用恒电压控制,第2条换流链上采用恒电流控制。首先推导出传递函数,并根据Bode图设计了控制器及其参数。通过Simulink仿真及现场试验,验证了该方案的有效性,为解决高压大容量链式STATCOM的全功率试验提供了一种新的方法。
英文摘要:
      Cascaded STATCOM of ±100 Mvar or higher-capacity must be experimented under full-power, but subject to the requirements of large-capacity equipment, such a test is very difficult. The traditional equipment of full power test is two sets of high-voltage chain STATCOM device on the drag, the cost is high, and the requirements of the lab and electric grid. In this paper, through a full DC power supply, the use of charging power and energy supply to build a new type of test platform, can effectively reduce the access to the power grid requirements. Constant voltage control is applied in the first convert chain,and constant current control is applied in the second. The transfer function is deduced, and the controller and its parameters are designed according to the Bode diagram. The effectiveness of the scheme is verified by simulink simulation and field test. It provides a new method for solving the full power test of high voltage and high capacity chained STATCOM.
