Coordinate Of Excitation Controller Based On Multi-layer Decentralized Structure

Based on the studying of large-scale system control theory, the paper have analyzed the merits and disadvantages of the hierarchical control theory and studied the actuality and development of decentralized control of power system. Then, aim at power system, a new algorithm of decentralized coordinated configuration for power system based on algorithm of decomposition coordinated of large scale system designing and optimizing is proposed, namely, there is a coordinated controller upon all power system excitation decentralized controllers. A sample system is solved and results show that system stability can be improved using this new algorithm of decentralized-coordinated configuration.
