Abstract

The invention discloses a remote dynamic display method for relay protection based on data integration, which includes: identifying a fault in the power grid; extracting the wave recording data file of the fault wave recorder, the intermediate node information file of the protection device, the wave recording file of the protection device, Fixed value for device protection; remove repetitive and irrelevant data, and regularize wave recording data; use the protection start time as the time reference point to perform time alignment and compensation for waveform data; take the time axis as the backbone, and The protection action information and protection self-inspection information are integrated; the information is converted into dynamic playback data with time as the main line; the data is dynamically played through the time control module, and remote browsing and playback can be performed through the webpage. The invention can sort out and merge various data at the time of failure, and dynamically display the action behavior of relay protection.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a data integration-based remote dynamic display method for relay protection. Background technique [0002] In the early stage of power system construction, due to backward technology and other reasons, the intelligence of the power grid dispatching system is not high, mainly relying on operating personnel to understand the operation status of each substation through the phone. With the continuous development of science and technology, automation technology continues to introduce new ones, intelligent dispatching system has been widely used in power systems, modern intelligent dispatching system is a real-time dynamic system, in order to fully understand the real-time operation status of the current power grid and relay protection, more To effectively analyze and deal with power system failures, the amount of monitoring information required for scheduling is quite large. ...
