Intelligent transformer substation test researching system

Abstract

The invention discloses an intelligent transformer substation test researching system. The system comprises a simulating primary system, simulating primary equipment, process level equipment, a process level network, spacing level equipment, a station control level network, a background monitoring system and a clock synchronization system. The structure of the system is constructed according to the actual secondary system of an intelligent transformer substation; and structurally, each part of the structure is kept highly similar to the secondary link of the actual transformer substation, functionally, each part of the structure can be flexibly adjusted according to test types, and in configuration, each part has practicability. Research on the new technology test of secondary system equipment of the intelligent transformer substation, secondary system equipment performance, the process level network networking way, the protecting device sampling / tripping way and the like can be carried out by the system.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a test and research system for intelligent substations. Background technique [0002] Smart grid has become the development direction of the future power grid, and the construction of smart substations has been in full swing. Whether the commissioning of a large number of smart substations will affect the power grid, whether the performance of digital secondary equipment can meet the requirements of safe and stable operation of the power grid, the optimization of the process-level networking mode, and other related issues of smart substations all need to be studied. An experimental research platform. [0003] At present, the existing smart substation secondary system simulation test system can be used to carry out the digital secondary equipment detection work, but the structure and configuration of the test system are only suitable for carrying out the test work...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing smart substation secondary system simulation test system can be used to carry out digital secondary equipment testing, but the structure and configuration of the test system are only suitable for testing digital secondary equipment itself, and cannot be used for smart substation testing. Secondary system to carry out effective research work

For example, an existing test system uses a PCI bus expander and an IEC61850 communication card to perform signal conversion on the test data generated by the system test host, and the converted data is used as a test signal source to detect the fully digitally protected secondary equipment; this There is a large difference between this structure and the secondary system structure of the smart substation, and it is impossible to conduct experimental research on the equipment of each secondary system of the smart substation
