Intelligent transformer tap control device and method

Abstract

The invention relates to an intelligent transformer tap control device and method. The intelligent transformer tap control device structurally comprises a power source module, a gear acquiring module, an output control module and an intelligent processing module. The power source module is respectively connected with the gear acquiring module, the output control module and the intelligent processing module. An output end of the gear acquiring module is connected with an input end of the intelligent processing module, an output end of the intelligent processing module is connected with the output control module, and the intelligent processing module is connected with a communication manager through an RJ45 Ethernet port. The intelligent transformer tap control device acquires gear signals, can adjust taps of a main transformer and has an automatic emergency stop function in case of gear sliding. After receiving voltage increasing or decreasing commands, the intelligent transformer tap control device can automatically judges gear changes, in case of gear sliding, stop connecting points of the taps of the transformer are controlled to act to transmit stop commands to a gear controller or voltage regulation mechanism, the taps are controlled to stop in time, and accordingly, remote control and adjustment are guaranteed to be reliable.

Description

technical field [0001] The invention relates to a transformer control device, in particular to an intelligent transformer tap control device and a control method, belonging to the field of substation automation. Background technique [0002] Aiming at the current method of remote adjustment of transformer taps by operating personnel and automatic adjustment of taps by reactive voltage automatic adjustment system, there is a certain degree of insecurity. The communication management equipment at the substation level sends the remote signal displacement signal or gear telemetry to the main station. When the operator finds that the gear is slipping, and issues an emergency stop command, the phenomenon that the remote adjustment slip is too large and cannot be stopped. [0003] The existing automatic protection device for transformer remote adjustment and sliding gear needs to collect voltage and set the gear change time. Complex and low reliability.
