探究PLC分级递阶控制在变电站综合控制中的应用

Research of PLC Hierarchical Control in Comprehensive Control of Substation Application

在电力系统中变电站是具有极其核心的主要环节,也是整个电力系统中不可或缺的重要组成部分。一切电能的转换、电能的再分配等复杂和繁重的工作必须由它来完成,并且它要对整个电网负责。随着当今经济社会的快速发展,一些陈旧的、过时的变电站以及老式的设备等等已经不能适应时代发展的需要了,它们无论在功能方面还是在安全可靠的系数方面都存在着较大的风险,根本不能满足现代化电力系统在各方面的基本要求。因此,为了安全用电,提高电力系统运作水平和管理水平,建设一个自动化综合变电站,以适应时代发展的需要,尤为重要。

In the power system transformer substation is a extremely the core of the main link, is also the whole electric power system art important part of. All power conversion, the redistribution of power, such as complex and hard work must by it to complete, and it to the whole power network is responsible for. With the rapid development of economy and society, some old, obsolete substations and old equipment and so on already can not adapt to the needs of the development of The Times, they both in function and in the safe and reliable coefficient there is a greater risk, unable to meet the modem power system in all aspects of basic requirements. Therefore, in order to use electricity safety and to improve power system operation level and management level, build a comprehensive automation substation, so as to adapt to the needs of times＇ development, particularly important.
