Abstract

The invention discloses an intelligent relay protection device control overhauling method based on on-line monitoring information. The overhauling method comprises a self on-line control overhauling process of an intelligent relay protection device and an on-line control overhauling process of an external loop of the intelligent relay protection device. Through self conditions of the intelligent relay protection device, real-time monitoring of the on-line control overhauling mode is carried out, regular overhauling is not needed, early warning can be achieved according to thresholds of operating parameters, real-time monitoring of the connected network state is carried out through the intelligent relay protection device, alarm of the loop of the intelligent relay protection device is achieved, safe isolation and fault positioning are completed automatically, and the overhauling method is convenient to use and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to a control and maintenance method for an intelligent relay protection device based on online monitoring information. Background technique [0002] With the application of the IEC61850 standard in the smart grid, smart substations have been promoted and constructed on a large scale in recent years. However, the smart relay protection devices operating in the substation are facing a lot of maintenance work, and the smart relay protection devices are different from conventional Due to the characteristics of the device, the traditional regular maintenance has a large workload and redundant redundancy, which affects the reliability and economy of power supply. [0003] Therefore, it is necessary to find a maintenance plan, through the online monitoring information of the intelligent relay protection device, to realize the transformation from regular maintenance...
