反应堆保护系统的执行器闭锁试验

The Blocked Actuator Test on Reactor Protection System

为了降低反应堆保护系统在进行执行器闭锁试验时面临的系统性风险,提出一种新的闭锁试验设计方法。该方法以试验执行时间最短作为最优化目标,并且一旦检测到自动保护命令就退出试验。本文基于Nicsys~8000N安全级DCS平台介绍了该方法的工程应用。

In order to reduce the systemic risk of reactor protection system in the process of the blocked actuator test,a new design method of the blocked test is proposed.The method takes the shortest test execution time as the optimization objective and exits the test once the automatic protection command is detected.This article describes the engineering application of this approach based on Nicsys 8000 N safety class DCS platform.
