Intelligent transformer substation system grade time characteristic testing device

Abstract

The invention discloses an intelligent transformer substation system grade time characteristic testing device, comprising a data transmission system and a data analysis system. The data transmission system comprises a standard signal collection module, a data processing forwarding module and a synchronization signal output module; the standard signal collection module and the data processing forwarding module are connected to a data analysis system; and the output terminal of the synchronization signal output module is connected to the input terminals of the standard signal collection module and the data processing forwarding module. The invention can realize the time characteristic test on a merging unit to be tested, a protection measurement control device and an intelligent switch device, greatly improves the conditioning speed of the intelligent transformer substation, provides good technical guarantee to the development of the intelligent transformer station, and lays solid foundation to safety stable operation of the intelligent transformer station.

Description

technical field [0001] The invention relates to the technical field of detection and calibration equipment for intelligent substations and digital substations in electric power systems, in particular to a system-level time characteristic testing device for intelligent substations. Background technique [0002] Smart substation is an indispensable part of smart grid construction. Compared with traditional substations, the sampling and control signals between electrical equipment in smart substations are increasingly transformed from traditional cable analog transmission to optical fiber digital transmission, which also brings about the instability of data information transmission. , where the instability of time performance is particularly obvious. The conformance test of the EC61850 (DL / T860) standard provides relevant regulations and explanations for the system performance test. The conformance test document puts forward two requirements for the performance test, which are...

Problems solved by technology

Judging from the current situation, the existing relevant testing instruments and tools on the market can only test different intelligent electronic devices such as merging units, intelligent terminals, protection measurement and control, etc., breaking away from the integrity and systematic testing requirements of intelligent substations. The test efficiency is reduced, and the test method generates test signals by the test equipment itself, which cannot fully reflect its real operation; the test process relies on the standard clock source and its accuracy, and requires the test equipment to have the ability to access and output timing signals. Reduced test compatibility, increased complexity and difficulty of field test loops
