AP/CAP系列核电站冷态性能试验电源需求分析与措施

Analysis of Power Supply Demand for Cold Functional Test of AP/CAP Series Nuclear Power Plants and Relevant Measures

对比分析了AP/CAP系列与M310冷态性能试验差异性。基于AP/CAP系列冷态性能试验特点,从工艺系统、仪控系统电源需求出发,对电源稳定性进行了风险分析,提出了220 kV辅助电源供电下的AP/CAP系列核电厂冷态性能试验电源配置方案,以期为后续相关工作提供参考与借鉴。

This paper first compares the differences between AP/CAP series and M310 cold state functional test.Then it performs a risk analysis on power supply stability by combining the characteristics of AP/CAP series cold state functional test and the power demand by process system and instrument control system.It further puts forward a power supply configuration scheme fot AP/CAP series cold state functional test which mainly employs a 220 kV auxiliary power source.The paper is expected to provide some useful information for similar work in future.
