A local multimachine control system with simplified output feedback undisturbed by both primary and local power systems fluctuations

説明

A multimachine power network control system is investigated to enhance the stability of a local multimachine power system connected to a large-scale primary power system. The control system is designed on the basis of modern control theory. The system is first designed in the form of state feedback. For much easier applications, a practical extension to a control system with simplified output feedback is investigated. The control system is further characterized by the following: the system is effective in controlling disturbances from the primary power system, although the system based on the conventional design is occasionally disturbed by the primary power system's fluctuations. A decentralized control system is so designed that each machine's control system can be designed independently from the others, and realized one by one in the local power system.
