集中式用电信息采集系统主站建设与应用

为提高采集系统的稳定性和可靠性，采用基于集群技术的设计思想，构建数据库服务器、应用服务器、采集前置服务器等系统架构，实现高可用的集中式用电信息采集系统。并从电力营销应用的角度，比较分析系统的采集率、投运率、线损率等指标情况，与分布式采集系统相比，集中式采集系统具有较大的优越性，并对系统的特色功能做了简要分析。

Construction of Centralized Power Information Collection System Main Station and Its Application

In order to improve stability and reliability of the collection module of the power information collection system, the clustering techniques are leveraged to build the database server clustering, the web server clustering and the data acquisition server clustering. As a result, it can realize high availability of the power information collection system. Compared with the distributed collection system from the aspect of power marketing, the centralized power information collection system is better than the distributed one in terms of the collected rate, the operation rate and the line loss rate. At last, this paper brings a brief analysis on system features.
