Phasor data processing system based on intelligent telecontrol

Abstract

The invention discloses a phasor data processing system based on intelligent telecontrol. The phasor data processing system comprises a PMU communication module, a WAMS master station communication module, a data caching module, a dynamic wave recording storage module, an SDB bus interface module and the like, wherein the PMU communication module is in data communication with a PMU device, the WAMS master station communication module is in data communication with a WAMS master station, the data caching module connected between the PMU communication module and the WAMS master station communication module enables phasor data of a plurality of PMUs to be cached and sorted according to cross sections produced at the same time so as to form real-time data frames of the full station, the dynamic wave recording storage module connected with the data caching module stores one dynamic wave recording file per minute according to a preset speed, the SDB interface module connected with the data caching module enables the phasor data to be converted into floating-point type data to be put in storage, and a uniform access interface is built for the stored data. The phasor data processing system based on the intelligent telecontrol enables an intelligent telecontrol machine to be capable of processing high-frequency, high-real-time-performance and large-data-quantity synchronous phasor data.

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
