随着电力系统规模的不断扩大,稳定控制装置的二次开发工作面临巨大压力。在分析电网安全稳定控制策略实现特点的基础上,提出了一种标准化稳定控制装置中策略搜索匹配状态机模型。该模型通过将稳定控制策略归纳为运行方式集、当前运行方式、故障状态集、控制措施集、运行方式变化、策略搜索匹配共6个元素,与Mealy型有限状态机模型建立一一对应的映射关系,形成统一的数学表达。这种标准化的数学表达式物理概念清晰,逻辑关系明确,表达形式简洁,与实际系统的动态过程十分吻合,实现了策略表与搜索匹配的解耦,简化了软件编制和测试的流程。实际工程测试表明,所建立的模型提高了稳定控制工程实施的整体效率。
With the continuous expansion of power system, the secondary development of stable control devices is under great pressure. Based on the analysis of the characteristics of the control strategy of power grid safety and stability, a model of strategy search matching state machine in a standardized and stable control system is proposed. The model integrates the stability control strategy into the Mealy-type finite state machine model with one-to-one mapping by summarizing the operation mode set, the current operation mode, the fault status set, the control measure set, the operation mode change, the strategy search match, Relationship, form a unified mathematical expression. This kind of standardized mathematics expression has a clear physical concept, a clear logical relation and a concise form of expression, which is in good agreement with the dynamic process of the actual system. This realizes the decoupling between strategy table and search matching and simplifies the process of software compilation and testing. The actual engineering test shows that the established model improves the overall efficiency of the stability control project implementation.
