MiCOM P系列综合保护测控装置在发电厂的应用

Application of MiCOM P Series of Integrated Protection and Control Device in Power Plant

大唐马鞍山第三发电厂2×660 MW超临界机组6 kV厂用电系统保护采用上海AREVA电力自动化有限公司MiCOM P系列微机综合保护测控装置。文中介绍该装置因设计中施工图的设计没有注意细节,后来在进行保护装置选型、二次回路设计、保护定值整定计算、保护逻辑编写、保护装置校验过程中发现了MiCOM P系列微机综合保护装置在应用时必须注意的一些问题,并提出了改进方法。

The 6 kV auxiliary power system protection of DaTang Ma＇ an Shan third power plant 2 × 660 MW supercritical units using MiCOM P series microcomputer integrated protection and control devices of Shanghai AREVA Electric Power Automation Co., Ltd.. This paper introduces the design of the device due to the construction plans are not designed with attention to detail,and later carrying out protection device selection,the second circuit design to protect the value of setting fixed terms,protection logic preparation,protection device was discovered during validation MiCOM P series computer integrated protection device in the application necessary to pay attention to some problems and proposed the improvement method.
