Development Of SSP510 Frequency Voltage Emergency Control Device

With the construction of UHV grid and smart grid, the structure and scale of China's power grid has been greatly changed. So new requirements for frequency voltage emergency control device are presented. Architectures and features of the device is first introduced, followed by intelligent plug-management device is described, then the front end of correction algorithm based on DFT resampling is described. Additionally, the method for precise load shedding in smart substation, and the realization of standard human machine interface display and interactive method based on the C/S model are introduced. The engineering application of the device is introduced in the end.
