【摘要】 随着杭州电力信息集成工作的开展,如何合理利用信息集成平台已成为亟待解决的问题。文中指出信息集成平台应当是现代能量控制中心集成化工作的组成部分,其作用是为进一步实现控制中心的信息化、智能化和自动化而服务文章中介绍了为杭州电力信息集成的发展所做的规划工作即在符合 IEC 61970 标准的规范化集成平台上建立数据中心:第一阶段将建设数据仓库、拓扑检错、故障诊断和负荷特征提取功能;第二阶段将建设基于信息理论的操作票专家系统、电力用户特征提取、输电元件故障预警以及元件可靠性统计功能;第三阶段将建设运行风险评估功能和参数估计功能。更多还原

【Abstract】 Along with the implementation of electric power information integration for Hangzhou power network, how to reasonably utilize the information integration platform becomes a problem that has to be settled urgently. The authors point out that this information integration platform should be a component in the integration of modern energy control center and further provide the service in the realization of informatization, intellectualization and automation of the control center. The planning work for developing the power information integration of Hangzhou power network, i.e., to build up a data center on the normalized integration platform conforming with the IEC 61970 standard, is presented. In the first stage of this work, the authors build up the data warehouse, topology error identification, online faulty diagnosis, and load characteristic extracting software; in the second stage the intelligent expert system for power network operation based on information theory, customer characteristic extracting, transmission line fault pre-alarming, and statistical analysis of reliability data for power system unit software; in the third stage the operation risk analysis and parameter estimation software. Some of the decision support software in the planning is tested while their result is reasonable.1 引言 近年来,浙江省杭州市及其周边地区的经济处于飞速发展时期,导致用电需求不断攀升。2003 年上半年杭州市全社会用电量同比增长 20.55%,缺电和电网重载等现象将在相当长的时期内使杭州电网的安全运行面临严峻考验,大面积停电的威胁加剧,2003 年 8 月发生的美加大停电更是给杭州电网的安全运行敲响了警钟。美加大停电事故所暴露出来的重要问题之一,是美国电网管理缺乏统一的调度协调措施[1,2]。与此问题相关的诸多原因之中,调度中心信息缺乏高效集成的问题需要引起关注。 本文应用现代化能量管理中心的观点[3],指出杭州电力调度中心应在集成化的基础之上,进一步开展信息化、智能化和自动化的建设工作。2 杭州电力信息集成工作简介 杭州电网各种信息系统孤岛林立、各自为政的更多还原
