Description
technical field [0001] The invention belongs to the technical field of power system fault detection, and in particular relates to a high-speed communication wave recording system and method based on a power system with a large amount of data. Background technique [0002] The power system fault recording device is a device that can automatically record fault data when the power system fails and oscillates. In recent years, different types of fault recorders have been widely used in power systems, and the recorded fault data has become an important basis for analyzing system accidents, especially relay protection action behavior. [0003] However, with the increasing scale of the power grid and the continuous improvement of the automation level of the power grid control system, the amount of data contained in the power grid control system is increasing. high demands. However, the existing power system fault recording devices generally have shortcomings such as low data thro...
