摘要
提出一种计及响应的电力系统防电压失稳在线综合控制策略.根据局部系统的广域测量信息,快速评估局部系统的电压稳定性.利用等值负荷分解后的转移负荷,建立一种在线计算各控制节点有功、无功对电压不稳定指标的灵敏度分析方法,以各控制节点有功、无功控制灵敏度指标制定综合控制策略.IEEE14节点系统的仿真结果验证了所提策略的有效性.
An online response-considering comprehensive control strategy to prevent voltage instability is proposed.Rapid evaluation of voltage stability of local systems based on wide area measurement information of local systems.Using the transfer load after the equivalent load decomposition,a sensitivity analysis method for calculating the voltage instability index of active and reactive power on the control nodes on line is established.Developing comprehensive control strategy with active and reactive power control sensitivity index of each control node.The simulation results of IEEE14 node system verify the effectiveness of the proposed strategy.
