Multipoint virtual data injection type intelligent transformer substation site debugging method

Abstract

The invention discloses a multipoint virtual data injection type intelligent transformer substation site debugging method. The multipoint virtual data injection type intelligent transformer substationsite debugging method comprises the following steps of (1) configuration analysis: determining a site test configuration of an intelligent transformer substation, a test data injection point quantityand a type; (2) data fitting: according to a sampling interval or a switch interval, virtualizing test data of all injection points; (3) sampling and switch loop debugging: debugging a sampling loopand a switch loop of the intelligent transformer substation; and (4) subsystem debugging: regionally debugging a secondary system of the intelligent transformer substation. The debugging method of theinvention is used to increase safety, reliability and economy of intelligent transformer substation construction engineering, a system acceptance period is effectively shortened, a guidance is provided for a lot of system-level tests in the further, and a good engineering application value is possessed.

Description

technical field [0001] This application relates to the field of testing of intelligent substations in electric power systems, in particular to a multi-point virtual data injection type intelligent substation on-site debugging method. Background technique [0002] Since the construction of the smart grid by the State Grid, the smart substation, as one of the "six cores" of the smart grid, has been widely used in engineering applications. The smart substation takes electronic transformers, merging units, and intelligent devices as the core, and is based on the transmission of digital sampling values ​​and the IEC 61850 communication system. advantage. [0003] Smart substations abandon the traditional substation method of transmitting electrical signals using cables as a medium, and use optical fiber to digitally transmit substation equipment operation information. Corresponding to the optical fiber digital transmission of information, smart devices such as electronic transf...

Problems solved by technology

On-site test equipment only has digital relay protection testers reported, and the price is expensive, the service cost is very high, and the operation is not friendly enough; domestic research on smart substation debugging mainly focuses on single-device testing, or pre-uses the simulation platform in the laboratory Carry out substation fault simulation, unable to verify the overall function of the system on site
