微机防误装置与其它防误装置的比较

目前电力系统内变电站防误装置使用种类较多,因此,变电站防误装置选型变得尤其重要,本文的目的就是为变电站防误装置的选型提供依据,确定较佳的解决方案。经过对各种防误装置全方位的比较,可以看出微机防误装置有非常大的优越性,实现的"五防"功能最完整、可靠性最高、运行维护量最少,且适应变电站综合自动化的要求,经济性也不差,是今后防误装置发展的必然方向,因此,建议变电站防误装置应优先采用微机防误装置。

Comparison between Microcomputer Error Preventing Device and Other Error Preventing Device

At present,there are many kinds of substation error prevention devices at power system.Therefore,the selection of substation error prevention devices becomes very important.The aim of this paper is to provide basis for the selection of substation error-prevention devices and to find the best solution.Through the all around comparison of various error prevention devices,we can see that microcomputer error preventing device is better than other devices which achieves ＂five-anti＂ feature of the most complete function,the most reliable,the least operation and maintenance.It also adapts to the substation automation requirements and is economic which is the development direction of error prevention devices,so it is suggested that the substation error prevention devices selection should give priority to the use of computer error prevention devices.
