| 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。 |

| Abstract: |
| The stabilizing controller of general affine nonlinear system is designed based on the pseudo- generalized 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. |
