Phasor Data Processing System Based on Intelligent Telecontrol

Abstract

The invention discloses a phasor data processing system based on intelligent telecontrol, including: a PMU communication module, a WAMS master station communication module, a data buffer module, a dynamic wave recording storage module, an SDB bus interface module, etc.; wherein the PMU communication module Realize data communication with the PMU device, the WAMS master station communication module realizes data communication with the WAMS master station; the data cache module connected between the PMU communication module and the WAMS master station communication module stores the phasor data of several PMUs by The same time section is cached and sorted to form a real-time data frame of the whole station; the dynamic recording file storage module connected to the data cache module saves a dynamic recording file per minute at a preset rate; the SDB interface connected to the data buffer module The module converts the phasor data into floating-point data for storage, and establishes a unified access interface for the stored data. By adopting the invention, the data volume of high-frequency, high-real-time processing and synchronous phasor data of the intelligent telematics machine can be improved.

Description

technical field [0001] The invention relates to a synchronous phasor data processing technology for integrated power grid operation, in particular to a phasor data processing system based on intelligent telecontrol. Background technique [0002] At present, my country's power system has problems such as the variety of secondary equipment, fragmented operation information, and lack of unified construction and operation standards. In this regard, domestic power companies have proposed an overall solution for building an integrated power grid operation intelligent system, and the intelligent telemotor at the station end is the mainstay of the overall solution. [0003] The intelligent telemotor is an intelligent communication management device for substations, used for data collection and telecontrol export of the whole station, integrating monitoring, conventional telecontrol, protection information, online monitoring, electricity metering, PMU, video collection and forwarding...

AI Technical Summary

Problems solved by technology

But at present, the synchrophasor data processing technology of the intelligent remote machine is not mature, and it cannot receive and process the phasor data, which hinders the development trend of unified data collection, storage and application at the station end
