一种变电站站用交流电源系统的改进方法

站用交流电源系统为变电站的运行提供稳定可靠的低压交流电源,是保证电网安全稳定运行的基础。对国内站用交流电源系统在逻辑、动作条件等方面的设计进行总结,提出了站用交流电源系统在运行中出现的若干问题,如开关无法与站用变保护配合、CT达不到保护级等,提出一种能改进站用交流系统智能控制模块逻辑的方法。

An improvement methodof station service system in the substation

Station service system provide steady and reliable low voltage AC power for substation function, and is the base of the security of power systems. The logic and action condition design of station service system is summarized in this paper. several problem,such as the cooper-ating of switch and station transformer protection,CT can′t achieve protected level is put forward during process. in this paper,a method is ad-vanced to improve the logic of intel igent control module of station service system.
