一种新的电力系统稳定控制策略表表述及存储方式

A new method of expression and storage on decision table for the stability control of power systems

通过对策略表的科学分析,提出了一种新的策略表表述和存储方法,该方法将安全稳定控制策略表分解为接线方式、潮流方式、故障信息、保护动作信息及控制策略五种基本策略元素,每一种策略元素均用一逻辑表达式表述,并将各策略元素间的关系用树表示,即以树状结构形式存放控制策略表。这种方法所生成的控制策略表不仅存储容量小、通用性强、易于修改,最重要的是易于实现通用的策略表查寻程序,从而保证了能够快速、准确、可靠地实现策略查寻。

A new method of expression and storage on decision table for the stability control of power systems is presented. The decision table of stability control is divided into five decision elements: mode of connection, mode of power flow, failure information, operation of relay protection and control decision. Each decision element is described as a logic expression. The relationship of different decision elements is described as a tree. The decision table of tree structure has advantages such as smaller memory requirements, stronger versatility, and easier modification.It is more important that the method is easy to implement the generalization of inquiry program of decision table.
