Description

technical field [0001] The invention belongs to the technical field of electric power monitoring and protection, and more specifically relates to a comprehensive protection device based on a digital signal processor. Background technique [0002] With the development of computer technology, microcomputer relay protection technology has been widely used in electric power. More substation systems and relay protection have been computerized and digitized. Basically banned the conventional relay protection equipment. Make the most of the computer's powerful data processing capabilities. [0003] However, most of the microcomputer protection devices on the market have huge functions, and few devices are suitable for most protection devices. The requirements for on-site application personnel are relatively high. Most of the functional configurations for protection devices in the system are configured according to objects, such as configuring transformer protection for distribu...
