A diesel generating set output characteristic field prover system is designed to overcome the defects such as single controller function, complex structure and low measurement precision. The STM32 processor with high performance is adopted as the core of hardware platform based on the modular design of the 485 control bus including AC electronic load module, electric energy quality analysis module and the temperature acquisition module. Finally, the framework of the host computer display control interface is completed to display,storage and record the real-time data as well as the control of the exchange of electronic load.The experimental results show that the diesel generating set output characteristic field prover system can provide AC electronic load for the measured diesel generators, measure the voltage, current, power, frequency, etc. information.The technicians work with real-time information exchange to determine the output characteristics of the diesel generator set whether to meet the technical requirements
