摘要

本文研究了核电站部件级和模块级更换对电磁兼容(EMC)评定的影响。近年来，仪表和控制(I&C)设备的组件或模块由于现有组件不可用和从模拟到数字的升级等多种原因而被替换。然而，这种情况很难找到测试实践和验收标准，而将整个系统作为初始EMC验证存在不切实际的方面。研究了器件级或模块级更换的实际EMC认证的技术报告和行业标准。分析了韩国核电站数字控制柜样机的电磁兼容特性，重点对POSAFE-Q可编程控制器进行了卡式模块组态变化的建模和电磁仿真。

A Study on Impact of Component and Module-Level Replacement on Electromagnetic Compatibility Qualification in Nuclear Power Plants

Impact of component and module-level replacement on electromagnetic compatibility (EMC) qualification in nuclear power plants is studied in this paper. Recently component or module of instrument and control (I&C) devices is replace for many reason such as unavailability of the existing component and upgrading from analog to digital. Nevertheless, it is difficult to find testing practice and acceptance criteria for the situation but there is an impractical aspect to test the whole system as the initial EMC verification. Technical reports and industrial standards for the practical EMC qualification of component or module-level replacement are investigated. The prototype digital I&C cabinet in Korea nuclear power plant is analyzed to evaluate the EMC characteristic and especially the modeling and EM simulation of POSAFE-Q programmable logic controller with card type module configuration change is performed.
