摘　　要：为保障安全稳定控制系统的可靠经济运行,提出了基于多层随机优化的电网安全稳定控制装置机会检修决策方法。分析了安全稳定控制装置投入运行后的状态转移过程,考虑安全稳定控制装置内部硬件之间、安全稳定控制装置之间、安全稳定控制装置和一次设备的关联性,从3个层次统筹安全稳定控制装置的功能关联、经济关联及随机关联,构建了嵌套复合目标函数,从而建立了多层次安全稳定控制装置机会检修决策模型,并通过算例表明了该模型能够提供安全稳定控制装置的最佳检修策略,提高安全稳定控制装置的检修效益,并实现安全稳定控制装置检修与电力系统运行的有效平衡。In order to ensure the reliable and economical operation of security and stability control system,an opportunistic maintenance decision method based on multi-layer stochastic optimization for power grid safety and stability control device is proposed.The state transfer process of security and stability control device in operation is analyzed.Considering the correlation between internal hardware of security and stability control devices,security and stability control devices,security and stability control device and primary equipment,the functional correlation,economic correlation and random correlation of security and stability control device are coordinated from three layers.Then the nested compound objective function is constructed to establish the multi-layer opportunistic maintenance decision model of security and stability control device.An example is given to show that the model can provide the optimal maintenance strategy of the security and stability control device,improve its maintenance benefit,and realize the effective balance between its maintenance and power system operation.
