摘　　要：对发电厂继电保护整定计算系统的智能化进行了研究,提出了面向操作的智能化设计思路。以人工操作最小为原则,采用图形文件识别实现了全自动图形建模,通过'数据-公式-保护装置模板-实例'多层知识结构构建了智能整定计算模块,使用模式匹配方法完成了整定结果与外部定值单无格式约束的直接对应。基于多层知识结构构建了较为完备的知识库,开发了一套兼具智能性与通用性的发电厂继电保护整定计算智能系统。系统已在某火力发电厂得以应用,效果良好。This paper studies the intellectualization of the power plant relay protection setting calculation system and puts forward the ideas of operation-oriented intelligent design. On the principle of the least manual operation, adopting graphic file identification technology, it has achieved full-automatic graphics modeling, through a multi-layer knowledge structure of ＂data-formula-relay protection device template-example＂, constructed the intelligent setting calculation module. And using pattern matching method, it has finished direct correspondence between setting calculation results and setting value sheets without formats constraining. In addition, based on the multi-layer knowledge structure, a more complete knowledge base is built; finally an intelligent system of power plant relay protection setting calculation with both intelligence and generality is developed. This intelligent relay protection setting calculation system of power plant has been used in a coal-fired power plant and achieved good effects.
