核电厂高压电气断相故障仿真分析

Analysis of Simulation in Electrical Open-Phase Malfunction of High Voltage in Nuclear Power Plant

核电厂高压电气断相故障,在实际电厂运行中主控室无法监测到。而现有分析仅仅是从电网设备角度分析,核电厂无法得到电网计算分析结果,是业内断相问题分析的空白。将电网断相计算分析模型与核电厂全范围模拟机系统模型集成在一起,能够从电网侧和核电厂工艺系统运行设备侧完整分析出断相后核电厂运行情况。将成熟的电网断相计算与模拟完善的模拟机软件通过接口开发,连接在一起进行多种电压等级断相故障测试是难题,通过三相电机模型开发,接口转换工具开发等处理,很好的解决了两种计算模型的接口问题,之后的断相测试结果,为核电站在断相故障发生后的快速反应提供了重要的依据。

Open-phase fault in mid and high voltage in nuclear power plant,cannot be detected in the control room of the power plant.But the existing analysis is only from the perspective of grid equipment,The nuclear power plant cannot get the calculation result of the grid,which is blank in the analysis of open-phase fault.The open-phase calculation model of the power grid was integrated with the full-scale simulator system model of the nuclear power plant in this article,which can analyze the complete result of the nuclear power plant with the open-phase fault from the grid side and the equipment side.The interface problems between the two calculation models can be well solved by the development of the three-phase motor module and interface conversion tools.The subsequent test results provide an important basis for the rapid response of the nuclear power plant after the open-phase fault.
