电网自愈控制方案

电网自愈控制以面向过程的预防控制为主要手段,以电网不失负荷为控制目标,强调工况适应,强调全局与局部的协调。讨论了由双环控制逻辑、3层控制结构、6个控制环节构成的"2-3-6" 电网自愈控制体系结构。以"2-3-6"自愈控制框架为主线,叙述了电网自愈控制的概念和体系,简述了电网自愈控制的相关问题。

Scheme of Self-healing Control Frame of Power Grid

Self-healing control is a new concept of power grid security control and the development of SCADA and EMS. Based on the measurement of time process and with the prevent strategy, self-healing control has the capability of automatically anticipating and responding to disturbances while continually optimizing power grid performance. Making power grid run continuously without load loss is the goal of self-healing control. The "2-3-6" frame, including two control circles, three control layers and six control links, is a suitable architecture for self-healing control. The "2-3-6" frame naturally has the coordinative abilities and is an effective way to solve the contradicting problems between slow grid-decision process and fast local-controlling actions. Some important problems of self-healing control of power grid is also discussed.
