The low frequency and low voltage load-shedding device needs to collect station electrical quantities for system level coordination processing, and the SSP-8000 power plant measurement and control system based on information and communication technology provides basis platform SSP-8000 for it. The hardware structure and software framework of the load-shedding device based on SSP-8000 platform are described, and the design and function of each sub-module of the software are introduced. Through the electrical quantities of the whole substation obtained from the measurement and control platform, the low frequency and low voltage load-shedding device realizes the function of precise load shedding. Digital simulation results are given to validate the effectiveness of the device. The device has been successfully put into test run in Hunan, and its operation result is good.
