摘要
The present invention relates to an on-load tap changer control method for a power excitation chain (1), said chain (1) comprising a generator (3), a step-up transformer (5) equipped with an on-load tap changer (7) and connected on the one hand to the output of said generator (3) and on the other hand to a transmission bus (9), and an excitation control system (11) comprising a generator automatic voltage regulator (AVRG) and at least one excitation limiter (OELG, UELG), comprising the following steps : monitoring the excitation conditions of the generator, activating said at least one excitation limiter (OELG, UELG)when the monitored excitation conditions are outside a predefined range, inhibiting temporarily the change of step of said on-load tape changer (7), when said excitation limiter (OELG, UELG) is active.
