DCS机柜用电现状分析

Current Situation Analysis of the DCS Cabinets Power

本文针对核电厂DCS机柜对电源系统用电需求过大,导致电源系统设计裕量较大,不利于核电厂经济性提升的问题,首先在梳理以往核电项目DCS机柜用电需求的数据基础上,对不同堆型、不同平台、不同类别机柜用电进行实地测量;其次充分阐述并分析说明机柜用电需求理论值与实际测量值的区别与差异,以及两者之间的数据关系;最后对核电厂DCS机柜用电分析的进一步优化进行了展望。

In view of the high power demand of DCS cabinet and the power system with more overmeasure during the nuclear power plant design,it make to the disadvantage of economic improvement,so the situation of high power demand were summarized in this paper.First,the power demand for different types of nuclear power plant,different platforms,different categories of DCS cabinets were measured in the field,based on combing the input data of previous projects.Then,the difference and the relationship of between the theoretical and actual input power demand data for DCS cabinets and were stated and analyzed.Finally,how to optimize the input power demand data of DCS cabinet in nuclear power plant is prospected.
