摘要
目前UPFC示范工程中采用防止线路功率越限的控制策略,系统级控制策略尚需进一步研究完善。提出了一种基于UPFC进行安全稳定预防控制的方法,针对电力调度中心在线安全稳定评估中发现的预想故障安全稳定问题,在线路过载和母线电压越限控制灵敏度计算的基础上,获得UPFC线路串联端有功/无功潮流控制以及并联端无功功率控制值并下发执行。某实际电网的算例结果表明,该方法进一步拓展了UPFC系统级功能应用范围。
At present,the control strategy is adopted in the UPFC demonstration project to prevent the line power from exceeding the limit,but the UPFC system-level control strategy has yet to be further studied and improved. In this paper,a method of security and stability preventive control based on UPFC is proposed. Aiming at the expected fault security and stability problem found in the online security and stability assessment of the power dispatching center, based on the calculation of the sensitivity of line overload and bus voltage overrun control,the active/reactive power flow control value of UPFC line series terminal and the reactive power control value of parallel terminal are obtained and then issued for execution.The proposed method further expands the application range of UPFC system level function,and an example of an actual power grid has verified the effectiveness of the method.
