Abstract

The invention relates to an independent wave recording system and a wave recording method for series compensation equipment. The system includes a platform measurement box, which is used to perform AD conversion on the collected transformer data and send them to the control and protection through the ST optical fiber interface. device and wave recording device; the control protection device is used to send the three-phase synchronous signal to the platform measurement box and the GOOSE switch signal to the wave recording device; the wave recording device is used to record the GOOSE switch signal and SV signal sent by platform measurement box. The technical solution provided by the invention comprehensively improves the reliability and objectivity of the wave recording mode of the series capacitor compensation device, and provides an important basis for analyzing system faults. The safety, stability and reliability are high, and the independent wave recording method has the least impact and modification requirements on the existing data acquisition system of series compensation, and minimizes the uncertain factors of these links.

Description

technical field [0001] The invention relates to a transient fault wave recording technology of a series capacitor compensation device, in particular to an independent wave recording system and a wave recording method for series compensation equipment. Background technique [0002] With the increasing application scale of series capacitor compensation device (referred to as series compensation) in EHV and UHV power grids, while it exerts huge economic and social benefits, higher requirements are put forward for its stability and reliability. Therefore, there is a need for a fault recording device independent of series compensation relay protection and safety automatic devices. It can record the electrical quantity and state change process information before and after the grid fault occurs, and completely reflect the instantaneous changes after the fault and the relay protection. Action behavior, and has the ability of data archiving and data reanalysis. Therefore, it is poss...
