摘　　要：频率控制一直是互联电网运行所关注的问题之一,基于特高压输电系统下频率控制的新需求,结合我国电网"统一调度、分级管理"的五级调度管理模式,在深入剖析北美可靠性标准集的基础上,提出我国频率控制应按照扰动严重程度划分的思想,并设计适合大功率缺失故障下频率整体控制的扰动控制性能评估方法与对国网、区域网和省网的三级调度方案。仿真结果表明,面向各类功率扰动的互联电网频率控制性能评估方法较北美扰动控制方法频率控制效果好,可有效提升系统抗扰动能力,对系统安全稳定运行有利。Frequency control has always been one of the concerns in the operation of interconnected power grid.Considering new demand of frequency control in UHV transmission system,combined with the five level dispatching management model of ＂ Unified Dispatch,Hierarchical Management ＂ in China power grid,the control thought that frequency control in China should be divided according to the dimensions of disturbance severity is proposed. And the performance evaluation method of disturbance control suitable to integral frequency control under high-power loss fault as well as the three level scheduling schemes for state grid,regional grid and provincial grid are designed on the basis of indepth analysis of North American reliability standard set. The simulation results show that the performance evaluation method for frequency control of interconnected power grid concerning all kinds of power disturbances has better frequency control effect than the disturbance control method of North American. The new method can improve anti-disturbance ability effectively and is beneficial to safe and stable operation.
