Abstract

The invention discloses a test system and method for a speed regulator of a nuclear power station 6.6KV emergency diesel generator system. The system comprises a simulation controller, a PXI case and a signal converter. A test signal generated by the PXI case under the control of the simulation controller is subjected to digital-analog conversion and first matching processing conducted through the signal converter and then transmitted to the speed regulator, a response signal generated by the speed regulator is subjected to second matching processing through the signal converter to be transmitted to the PXI case, the PXI case conducts analog-digital conversion on the response signal and transmits the signal to the simulation controller, and the simulation controller conducts waveform comparison and analysis on the response signal to determine dynamic parameters and static parameters of the speed regulator to obtain a test result. By means of the test system and method, a plurality of simulation and / or simulative input signals can be provided for the speed regulator under the condition that the speed regulator is off-line and open-loop, and the dynamic and static response characteristics of the speed regulator are compared and analyzed by measuring the response signal of the speed regulator in real time to finish the timely accurate test of the speed regulator.

Description

technical field [0001] The invention relates to a debugging technology for a 6.6KV emergency diesel generator in a nuclear power plant, and more specifically, to a test system and method for a governor of a 6.6KV emergency diesel generator in a nuclear power plant. Background technique [0002] The 6.6KV emergency diesel generator system is used as the emergency power supply of the nuclear power plant, and provides emergency power to the specially designed safety facilities in the event of a nuclear power plant accident. The governor of emergency diesel generator is the core of diesel engine control, and its working stability and performance directly determine the availability of emergency diesel generator. Due to the long-term online operation of the governor of the emergency diesel generator, the aging of components such as capacitors, optocouplers, and resistors on the circuit boards of each equipment leads to changes in the performance of the boards, which has a potentia...
