智能判断技术在变电站站用变电源系统的研究与应用

Research and Application of an Intelligence Judgment Technology in the Substation Transformer Power Supply System

依据珠海电网系统变电站站用电源的结构变电站通信电源的特点,提出了珠海地区所有变电站站用电源系统中采用专家系统进行在线预判的方法。详细描述了站用变交流系统中在线预判断异常信息和推理机制,以及获取异常信息的方法,设计了相关的应用软件,并编制了应用软件,模拟了变电站站用变交流电源系统的事故情况。经过现场实践检验,证明该系统具有实用性,是值得推广的在线判断系统。

Based on the characteristics of the communication power supply of the substation power supply in Zhuhai power system, this paper proposes that an expert system method be used for the online pre-judgment for the substation power supply for all the substations in Zhuhai area. The paper expounds the on-line pre-judgment of the abnormal information and reasoning mechanism in the AC system of the substation power supply and methods of acquiring the abnormal informa-tion,and designs and compiles the related application software.Incidents of the AC power supply system for substations are simulated too. The field application has proved that the online pre-judgment system introduced in this paper is feasible and practical and worthy promoting.
