Problems solved by technology

[0002] In recent years, with the transformation and expansion of substations, the access capacity of substations has become larger and larger. Many Baoxin substations that have been in operation for many years have been operating at full capacity or close to full capacity. When catching up with extreme weather such as typhoon season, the power grid Faults occur frequently, and wave recording starts frequently, which puts great pressure on the data processing of sub-stations, and even affects the transmission of data to the main station for guarantee letter / secondary operation and maintenance, resulting in the main station not being able to accurately and timely understand the fault situation of the power grid

Abstract

The invention relates to a power grid fault data collection method and device. The method comprises the steps: a current operation mode of a power grid is judged according to a preset condition; underthe condition that the operation mode is a normal mode, a master station triggers a recording data request in real time after receiving the recording brief report to obtain recording data; and underthe condition that the operation mode is an emergency mode, after the master station receives the recording brief report, a recording data request is triggered according to first preset time to obtainrecording data. In the embodiment of the invention, the calling efficiency is improved by providing the substation with a period of time focused on calling protection and recorder recording, so thatthe substation data pressure peak value is reduced, the substation data uploading capability is improved, and meanwhile, the master station can accurately and timely know the fault condition of the power grid.

Description

technical field [0001] The present disclosure relates to the field of electric power technology, and in particular, to a method and device for collecting grid fault data.
