从防止电力系统灾变发生的角度 ,阐述了进行电力系统灾变防治研究的必要性和迫切性。文中分析了电力系统灾变防治问题的难点和电力系统灾变防治系统研究中的特殊问题 ,对电力系统动态安全分析、稳定控制、恢复控制、电力系统隐患的探测和预防以及连锁性故障发生的机理和控制策略等方面的研究现状及存在问题进行了简要概述 ,并指出了该系统最终应达到的目标和实现的可能性。 From the perspective of preventing catastrophic event of power system, the necessity and urgency of research on catastrophic control of power system are expounded. This paper analyzes the difficulties of power system disaster prevention and control and the special problems in power system disaster prevention and control system research. The dynamic safety analysis, stability control, recovery control, detection and prevention of power system hazards and the mechanism of cascading failure are discussed Control strategies and other aspects of the status quo and existing problems were briefly outlined, and pointed out that the system should ultimately achieve the goal and the possibility of realization.
