为了实现反应堆保护装置各功能单元的快速、自动化功能校验,设计反应堆保护装置校验设备。该设备通过基于现场可编程阵列逻辑(FPGA)的脉冲信号输出电路配合高速采集卡采样频率和缓冲区数据计数的方法,实现定值单元自检接口的测试;通过基于高精度恒压源、电压反馈、电流反馈模块的输出电路实现对高精度毫伏信号的模拟;通过故障定位专家系统实现对各功能单元的智能化故障定位。各项测试和试验结果表明,各项技术指标满足用户规定的要求。

In order to achieve rapid, automatic functional verification of each functional unit of the reactor protection device, a reactor protection device verification device is designed. The device through the field programmable array logic (FPGA) pulse signal output circuit with high-speed acquisition card sampling frequency and buffer data count method to achieve self-test unit fixed value unit testing; based on high-precision constant voltage source, the voltage Feedback, current feedback module output circuit to achieve high-precision millivolt signal simulation; fault location expert system to achieve the intelligent fault location of each functional unit. Various tests and test results show that the technical indicators to meet user requirements.
