Automatic voltage regulation method and automatic voltage regulation device for multi-gear voltage regulation transformer

Abstract

The invention discloses a multi-position voltage regulating transformer automatic voltage regulation method and an automatic voltage regulation device. The method comprises the steps of acquiring current gear position information of a voltage regulating transformer, calculating a difference value between the current gear position information and a target gear position number, determining the operation type of a gear-by-gear voltage regulating operation according to the difference value, sending the gear-by-gear voltage regulating operation under a remote operation mode to an intelligent controller, and terminating automatic voltage regulation when the number of action times of an electric operating mechanism of the voltage regulating transformer equals to the difference value between the target gear position number and the current gear position information. The multi-position automatic voltage regulation device comprises an intelligent controller, an electric operating mechanism, a man-machine interaction unit and a voltage regulation control module which are mutually connected, wherein the voltage regulation control module comprise a power supply unit, an interface module, a gear position signal acquisition module and a gear position gear-by-gear automatic regulation output module. The method and the device disclosed by the invention have the advantages of safe and reliable voltage regulation, ability of realizing cross-position and multi-position automatic voltage regulation, high regulation speed and convenient operation.

Description

technical field [0001] The invention relates to a test technology of a locomotive converter, in particular to an automatic voltage regulation method and an automatic voltage regulation device for a multi-gear voltage regulation transformer. Background technique [0002] In the locomotive converter test, using the on-load tap-changing transformer instead of the voltage regulator to regulate the voltage can obtain a relatively hard voltage characteristic, which requires the tap-changing transformer to have enough gears to meet the test requirements, but due to the The safety requirements of the transformer test require that the voltage should not increase suddenly. Therefore, the existing gear adjustment instrument of the voltage regulating transformer can only realize gear-by-gear adjustment, and cannot realize convenient automatic voltage adjustment. The adjustment time is long and the operation is cumbersome. Contents of the invention [0003] The technical problem to be ...
