A Brief Analysis of the Causes and Coping Strategies for the Alarm of the Excitation System During the Main Transformer's Power Transmission
This article analyzes the influence of sympathetic inrush current caused by the main transformer energization on the excitation system and proposes improvements to the stator current measurement fault logic of the excitation system to extend its alarm delay.Through simulation tests,it is confirmed that the modified logic has no impact on other functions of the regulator,thus solving the problem of excitation system alarms in adjacent units during main transformer energization.
