500 kV双龙变电所操作票自动生成系统

介绍了500kV双龙变电所操作票自动生成系统。提出了一种采用模型化设备、领域知识库、拓扑路径算法和推理机的实用的专家系统构成方案。系统采用多重产生式系统来构造专家知识库。提出了二次设备模型化，并构造了相应的知识库，解决了二次设备操作票自动生成问题。通过在线拓扑分析算法，推理出操作路径，使该系统具有很好的跟踪电网运行方式的能力。所设计的解释机，能对推理过程和知识利用情况进行详细解释。该系统在线利用SCADA实时信息，形成一在线智能生成与监视的闭环系统，并于1999年5月在金华500kV双在电所中投入运行。

AN APPROACH TO AUTOMATICALLY GENERATE SWITCHING SEQUENCES FOR 500 kV SHUANGLONG SUBSTATION

An approach to automatic generation of switching sequences for 500 kVShuanglong substation is presented in this paper. A method for developing an applied expert system is presented, which uses the technologies of modeling facility, special expert knowledge database, on-line topology analysis algorithms, inference engine and so on. To solve the problem of automatic generation of operation orders for secondary devices, secondary devices are first modeled, and then special expert knowledge database is created. By using an on-line topology analysis algorithm, the inference engine can search operation paths, and identify current operation status correctly. Having designed an explanation engine, the inference process and the used rules can be explained. A closed loop system for on-line intelligent generation and supervisory function is formed. Since May 1999, this system has been used at 500kv Shuanglong substation in Jinhua, Zhejiang Province.
