Hamilton Energy Theory Based Coordinated Control of Generator Excitation and TCSC

摘要

A coordinated control design algorithm based on Hamilton energy theory, -which has a simple physical meaning and is easily understandable to operators, is presented in this paper. The conditions how can the Hamilton function qualify as a real Lyapunov function are discussed and a stabilized control strategy is proposed via a concept of energy balancing and damping injection. A kind of long distance transmission power system, which can be equivalently seen as single machine infinite bus (SMIB) system, is represented into pseudo-generalized Hamilton system and the coordination of generator excitation and TCSC controllers is realized immediately with the proposed algorithm. The incorporation of decentralized input control signals will lead to a better stabilized performance. To illustrate the proposed approach, a simulation experiment has been performed for a practical power system. The results of the proposed coordinated control strategy are compared with previous decentralized one, which demonstrate the effectiveness and practicability of the coordinated controller proposed in this paper.
