Abstract

The invention relates to an intelligent substation secondary N-in-one device. When an abnormal module occurs in a secondary N-in-one device for executing protection, a mirror image is called to perform an overwrite protection algorithm on a backup general-purpose computing unit in another normal secondary N-in-one device that contains a lot of relevant information to complete a protection function of the electrical device. The risk brought by a single point failure of internal components of the protection device is avoided and the reliability of substation area protection of the intelligent substation device is improved.

Description

technical field [0001] The invention relates to a secondary N-in-one device of an intelligent substation, which belongs to the field of station domain protection of the intelligent substation. Background technique [0002] 1. The integration of secondary equipment is an important direction for the future development of the smart grid. The secondary intelligent unit with sensing measurement, logical operation, and communication collaboration capabilities is encapsulated in the primary power equipment, and the optical fiber is used as the information exchange support between the equipment, so that Build a networked, self-organized substation interactive protection and control system. According to the principle of modular design, the integration of primary and secondary equipment will simplify the construction process of the secondary system of the traditional substation and significantly reduce the assembly errors that may occur during the construction process. Compared with ...
