摘　　要：根据电力系统输电线路网络模型结构的特点,建立基于粗糙集(Rough Sets,RS)与有色Petri网(Coloured Petri Net,CPN)相结合的电网故障诊断模型。RS可在保留关键信息的前提下,对提取的故障信息进行约减并求得知识的最小表达,利用CPN对电力线路的结线分析功能建立CPN的电网故障诊断模型。通过实例验证表明本文提出的诊断模型的快速性和简便性,2种方法的结合不仅提高了故障诊断的通用性,而且降低了复杂故障的诊断难度。According to the characteristics of power system transmission line network model structure, this paper established a power grid fault diagnosis model based on Rough Sets（RS） and Coloured Petri Net（CPN）. Under the premise of keeping the key information, RS can reduce the extracted fault information and obtain the knowledge of the minimal expression. CPN, based on power line junction line analysis function, can build the CPN model of electric power grid fault diagnosis. Examples show the ra- pidity and simplicity of the diagnosis model, and the combination of two methods not only improves the generality of fault diagno- sis but also reduces the complexity of fault diagnosis.
