Embodiment Construction

[0010] The present invention will be further explained below in conjunction with the accompanying drawings.

[0011] see figure 1 , the digital substation distributed test system consists of a system integration test platform and more than one distributed test unit.

[0012] Among them, the system integration test platform: can obtain the configuration information of the whole station by importing the SCD file of the whole station, connect to the Ethernet network of the station control layer through the network, and can monitor and record all the data of the station control layer of the entire digital substation in real time, and according to the SCD The relevant information judges the rationality and correctness of the data; at the same time, the distributed test units are connected through the internal interconnection Ethernet, and each test unit is independently configured and commanded according to the SCD file, and the integrated test platform is used to complete the moni...

Abstract

A digital transformer station distributed test system comprises a system integration test platform connected to the Ethernet of a station control level and more than one distributed test unit. Each distributed test unit comprises a first Ethernet module, a second Ethernet module, SV / GOOSE message coding and decoding modules, electronic merging unit simulation modules, a B code time setting and 1588 time setting reception module, a man-machine interface control module and a lithium battery management control module which are connected to a CPU module. The first Ethernet module is also connected with the Ethernet of the station control level. The SV / GOOSE message coding and decoding modules are connected to a network of a process level through Ethernet interfaces. Through the combination of the system integration test platform and the distributed test unit, the digital transformer station distributed test system takes merging units, networks, switches, system configuration files and the like which achieve organization, distribution and transmission of signals of an intelligent transformer station as a functional body included in the test range of secondary equipment, so that the integrity and authenticity of testing is improved.

Description

technical field [0001] The invention relates to the field of testing of digital substations, in particular to a distributed testing system of digital substations. Background technique [0002] Since 2005, new technologies, international standards, power enterprise standards and power industry standards for domestic digital substations have been developing in an all-round way. Compared with conventional substations, digital substations have all digitized information collection, transmission, processing, and output processes, and their basic features are intelligent equipment, communication networks, unified models and communication protocols, and automated operation management. In the test of conventional substations, the organization, distribution and transmission of analog signals are intuitive and simple. Only the input signals of voltage and current transformers need to be replaced by analog signal sources, and the secondary equipment can be tested. In addition to the ci...
