STABILIZATION EFFECT OF MULTI-MACHINE POWER SYSTEM BY USING ADJUSTABLE SPEED GENERATOR

摘要

This paper describes a stabilization effect after installating an adjustable speed generator (ASG) in a multi-machine power system. A personal computer based ASG module has been developed for the simulations in parallel with the analog power system simulator in the Research Laboratory of the Kyushu Electric Power Co. The three-phase instantaneous value based ASG model has been developed in the Matlab/Simulink environment for its detailed and real time simulations, which have been performed on a digital signal processor (DSP) board with AD and DA conversion interfaces installed in a personal computer (PC). Simulational results indicate the highly improved overall stability of the multi-machine power system after installating the ASG.
