摘要
传统的电力系统操作票专家系统在通用性和智能性上存在着不足 ,其根本原因是专家系统的结构没有反映出对电网的认知过程。文中在认知科学中的概念认知理论指导下 ,深入研究了电网的认知过程 ,提出专家系统必须反映人类认知过程的基本因素——概念 ,同时还要反映出概念的创造和扩充。在此思想指导下 ,建立了通用的电网操作认知模型 ,该模型的核心是操作对象原子 ,它反映了人类专家在认知电网过程中创造的概念。操作对象原子之间具有继承性和层次性。操作对象原子可以动态地定制 ,这种可扩充性反映了认知过程中新概念的建立。电网操作认知模型的建立过程反映了对电网设备操作的认知过程 ,因此建立在该模型基础上的操作票专家系统具有良好的通用性和智能性。
Traditional operating comm and expert systems in power system have some weaknesses in practical application,such as lack of universality and intelligence.The main reason behind this is that the conventional developers did not consider the hum an cognition procedure of a power system.Therefore,under the direction of cognitive science,a deep research is m ade in this paper and the core of human cognition that is concept is introduced into expert system .The creation and extension of the concepts are also introduced.Based on it,a general cognitive model of power network operation CMPNO is developed.The core of the CMPNO is operating object atoms OOAs ,which is corresponding to the cognitive concept made by hum an.The OOAs have the properties of hierarchy and inheritance.As the OOAs can be defined dynamically and flexibly,the creation of CMPNO reflects the cognition of power system.A general operating comm and expert system based on CMPNO is developed and applied to a practical power system.Excellent ability of universality and intelligence of this CMPNO is verified.
