摘要
本文针对攀钢发电厂改造后的厂用电系统情况,对厂用电保护定值的整定配合、保护功能、电网安全稳定控制装置联切发电机机组时对厂用电系统运行可靠性等问题进行了分析并提出相应改进措施,从而改善厂用电系统保护性能,提高厂用电系统的可靠性。这些分析思路与改进措施,对厂用电微机型保护装置的研究开发与现场应用,有一定的参考借鉴意义。
In view of the system movement situation of station power after been transformed in Pangang Power Plant,the paper makes a detail analysis for the problem such as settings of protection,protection function,reliability influence on power network safe-stable-control device association tripped generator unit in station power and so on,and proposes countermeasures.The countermeasures improved on character of station power protection and enhanced reliability on system of station power.The analysis and countermeas...
