使用DCS系统后落棒试验信号同步分析

落棒试验是通过释放两束选定的控制棒,触发RPN系统的3个及以上通道的功率量程负通量变化快信号,并触发机组自动停堆。如果试验过程顺利,则可以证明机组保护系统响应的准确性与可靠性。试验结果处理中,如何将不同系统来源的不同类型信号按照相同的时间拟合到一起,找到将两个系统来源的信号关联到一起的公共变量成为试验处理的关键。

Rod drop test trigger the reactor automatically to trip by releasing two beams of selected control rod and triggering no less than three power range negative high neutron flux rate signals in RPN system. If the test went smoothly, it can prove that reactor protection system response accuracy and reliability. Processing test results, how to fit different types of signal of different systems together and how to find the public variables that associate signal source of two systems together become a key of test process.
