Abstract

An adapted regulator for the control of large turbogenerators is presented. The compensator consists of three feedback channels, the resulting signal being applied to the rectifier bridge of the excitation system. Because of the varying operating conditions and the possible disturbances in the power system, improved performance is obtained by adapting the gains of the feedback loops. The proper adjustments are selected using a look-up table of precomputed values. This adaptation scheme is implemented on a microprocessor. Experiments on a model machine show the performance of the regulator. Owing to the robust design of the control scheme, the regulator may readily be applied in practice.
