Abstract

The invention provides a device with an event recording function for protecting an electric power system, comprising a master control unit, an event recording unit and a protective processing unit; wherein the master control unit is used for monitoring a plurality of nodes in the electric power system; the event recording unit is connected to the master control unit, is used for recording a plurality of failure messages, forecast messages and self inspection messages and is provided with the function of power-down retention; and the protective processing unit is connected to the master control unit and is used for debugging and maintaining the nodes of the electric power system according to the messages recorded by the event recording unit. The device with the event recording function for protecting the electric power system can automatically record and analyze the event messages of the failure nodes of the electric power system, so as to debug and maintain the protective device.

Description

technical field [0001] The invention designs the field of power system fault analysis and protection, and in particular relates to a power system protection device with event recording function. Background technique [0002] With the improvement of the operation level of the power grid, dispatching centers at all levels require more information in order to grasp the operation status of power plants, power grids and substations in a timely manner, improve the controllability of substations, and then require more remote centralized control, operation, and feedback. Accident measures, etc., that is, adopt an unattended management mode to improve labor productivity, reduce the possibility of human error, and improve operational reliability. On the other hand, the application of advanced technical means such as contemporary computer technology and communication technology has changed the mode of traditional secondary equipment. In order to simplify the system, share information, ...
