现代工业技术的发展对配电系统运行的可靠性及其智能化管理提出了更高的要求，而微处理器技术的广泛应用及计算机系统可靠性的大幅度提高，使智能化电器元件得到快速发展，智能化电气管理系统应运而生。安科瑞的Acrel-2000型电力监控系统软件借助了计算机、通讯设备、变电所智能电力仪表等，为系统的实时数据采集、开关状态检测及远程控制提供了基础平台。该电力监控系统可以提供“监控一体化”的整体解决，主要包括实时历史数据库AcrSpace、工业自动化组态软件AcrControl、电力自动化软件AcrNetPower等。 本文以启东行政中心例，简单介绍Acrel-2000电力监控系统实现公共建筑项目中供配电系统自动化、智能化，同时提高供配电系统的安全可靠性，历史数据可追溯性等功能。 1项目介绍 启东市行政服务中心是政府派出机构，代表政府行使组织、协调、管理、监督职能，是集行政许可与服务为一体的综合性行政服务机构。2001年12月28日正式投入运行。中心分管理层和办事窗口，管理层内设办公室、综合协调科和投诉监督科，办事窗口目前进驻47个部门，设立380 个服务窗口，371名工作人员，现有行政许可审批事项827项，服务事项13项。 本项目属于公共建筑项目，项目的监控范围为:高压开关站以及7个变压器和相应的负载回路、监控回路共计305个，本项目中监控回路配置ACR系列网络电力仪表。为实现本建筑内的配电自动化，提高启动行政中心供电的安全性、可靠性、合理性，建设方委托安科瑞电气股份有限公司承建此项目的智能化配电监控系统。鉴于本项目中高压开关站以及7个变压器距离主监控室的数据采集器距离较近，方案时将所有数据总线直接铺设至系统主机所在的值班室内。
