一种新的35kV简易站远程监控方法

针对35kV简易站运行缺陷,本文提出了一种基于CDA901控制器的农村电网35kV变电站远程监控方法,使得在资金有限的前提下,远程监控系统得以实现。CDA901控制器主要芯片是DSPIC30F6012单片机并能实现三段式过流保护、三遥、重合闸等功能,每个站内均装设有数据汇总装置,该装置把站内所有控制器的数据汇总并转换通过载波机及光纤与调度端联系。该系统在试运行期间取得了良好的效果,改善了电能质量,提高了供电可靠性及电压合格率。

A New Remote Monitor Method for 35kv Simple Station

Aiming at 35kV simple station operation defects, a new remote monitor method for 35kv station in rural grid with low budget based on CDA901 controller is presented in this paper. The main component of CDA901 controller is a single chip named DSPIC30F6012 by which some functions like three steps over current protection, remote measuring, remote controlling, remote communication and reclosing switch can be realized. Data collec-tion device which gather the data from all controllers and exchange it with operation termination by carrier or optical fiber is installed in each station. It have got fine effect which include the improvement of electric energy quality、supplying reliability and voltage level in examination period.
