【摘要】 针对目前评价灵活交流输电系统(FACTS)系统稳态性能影响指标的不足,结合FACTS设备自身控制潮流和电压的工作特性,提出了一套全面评估FACTS设备对系统静态安全性影响的指标体系。建立了基于运行状况的晶闸管控制串联电容器(TCSC)、静止无功补偿器(SVC)、统一潮流控制器(UPFC)可靠性模型,并基于该模型提出了FACTS设备的控制策略,该策略以状态量越限值最小为控制目标。建立了采用蒙特卡罗仿真的概率评估算法。通过IEEE-57节点的计算验证了所提指标体系和算法的有效性。更多还原

【Abstract】 After analyzing the disadvantages of indexes used to evaluate Flexible AC Transmission System(FACTS)devices impact on system security at present,this paper proposes an index system to evaluate FACTS devices effect on power system steady state security by considering the working performance of FACTS to control power flow and bus voltage.Then the reliability models of Thyristor Controlled Series Compensator(TCSC),Static Var Compensators(SVC),Unified power flow controller(UPFC)based on operating conditions is proposed,and the control strategy based on these models is presented.At last,the probabilistic assessment method based on Monte-Carlo simulation is developed.Simulation result of IEEE 57-bus system shows the effectiveness of proposed index system and method.更多还原
