Abstract

See full text

The present application provides a method and device for controlling a generator-side terminal voltage of a converter, and a controller of the converter. The method includes: determining an upper limit of the generator-side terminal voltage based on a present voltage value of a direct-current (DC) bus of the converter, where the generator-side terminal voltage is a voltage of an output terminal of a generator, and the output terminal is connected to the converter; determining an optimal value of the generator-side terminal voltage that minimizes a present value of a generator-side current, where the generator-side current is a current of the output terminal of the generator; setting a target value of the generator-side terminal voltage based on the upper limit and the optimal value of the generator-side terminal voltage. The target value includes a control reference value of the generator-side terminal voltage.
