Turbine Governor Control System Comprehensive Performance Test System

摘要

The present invention relates to a turbine governor control system comprehensive performance test system that can integrally control the turbine governor control system in a nuclear power plant. The configuration is largely composed of a host cabinet 100 and a test cabinet 200. In the host cabinet 100, a signal for controlling the continuous turbine speed which is the same as the turbine speed sensor installed in the field and the voltage of the governor Control signals and logic signals, and the input and output of the signal for selecting the pressure and valve opening measurement signal measured by the governor of the field for each channel independently controlled by the user's computer operation. According to this control, the test cabinet 200 generates the simulated turbine speed signal generator 210 in which the frequency and amplitude are continuously varied according to the simulated turbine speed control signal of the host cabinet 100. In accordance with the voltage control signal, the ratio or stair voltage signal is output from the ratio and stair voltage signal generator 220, and the contact type logic signal input / output card 230 outputs the contact type logic signal output from the external governor to the test apparatus. Output to the TTL logic signal used in the computer and perform the reverse, the field data acquisition unit 250 measures and outputs both the pressure and the valve opening state measured in the field as a voltage signal, DC power supply unit 240 In the DC power supply stably provided to each of the above parts. Accordingly, the present invention can provide a stable simulated turbine speed signal that is the same as the actual speed detection in the field, can provide a logic signal to the computer, supply a stable power, reduce the number of tests, It can reduce cost loss, extend the life of the steam control valve, and shorten the test time with less manpower.
