摘　　要：基于伪广义哈密尔顿(Hamilton)理论设计了一般仿射非线性系统的镇定控制器,进而将包含静止无功补偿器(SVC)和发电机励磁的多机系统表示为伪广义Hamilton形式,该系统考虑了转移电导和SVC动态过程的影响。从能量的观点出发,利用鲁棒L2方法设计了发电机励磁和SVC非线性协调控制策略,并将该控制策略表示为易于量测和实施的形式。最后将所设计的协调控制策略与传统的独立分散控制进行对比,对3机9节点系统的仿真结果证明了所提设计方法的正确性和有效性。The stabilizing controller of general affine nonlinear system is designed based on the pseudogeneralized Hamilton theory.The multi-machine power system with SVC and generator excitation system is represented as a form of pseudo-generalized Hamilton system,which takes account of the impact of transfer conductance and SVC dynamics.The nonlinear coordinated control strategy of generator excitation and SVC,which is expressed as a readily measurable and applicable form,is designed by robust L2 method.The proposed coordinated control strategy is compared with the traditional decentralized control and the simulative results for a 3-machine 9-bus power system demonstrate its correctness and effectiveness.
