| Abstract | ||
| This paper describes the development of a multi-channel control scheme to enhance the perfo~mance of a superconducting generatins (SCG) unit operated in a multi-machine power system. The proposed control scheme is designed and impleniented in the governor control loop of the SCG to overcome problems resulting fsom the low inherent damping nature of the SCG, which has structure different from those of the con\,entional synchronous machines. The design of the controller is based on developing an equivalent model of the SCG, which includes the effects of interactions with other generators. This simplifies the design procedures and produce control structure that use control signals measured from local generators only. The effectiveness of the controller is demonstrated by a detailed digital computer sirnulation of a multi-machine power system. The system consists of a 12-bus, 4-generators one of them is a 2000 MW SCG. The perfo~mance of the proposed controller is obtained and assessed in comparison with others, obtained using controllers designed by conventional techniques. It has been clearly denionstrated that the new controller improves the performance of the SCG, on which the controller is installed, as well as of all other generators in the network. | ||
