摘　　要：为提高系统电压的稳定性,针对电力系统非线性微分代数系统,在含STATCOM的结构保持多机系统中设计了相应的非线性稳定控制器,提出了有利于控制设计的功率注入STATCOM新模型;运用广义Hamilton系统理论设计了含STATCOM的结构保持多机系统的控制策略,并提高系统对扰动的鲁棒性。对含有STATCOM的典型3机9节点系统进行仿真的结果表明了所提出控制策略延长了系统临界故障时间,证明该策略可提高系统暂态稳定性。Considering nonlinear power system with the form of differential algebraic system,we proposed a new nonlinear STATCOM controller structure which contains multi machine power system applying the generalized Hamiltonian system and relevant control strategy. The power injection based STATCOM model was the object in controller design. And the STATCOM controller in multi machine power system was obtained to improve the system robustness,which had precise mathematical and physical meaning. Simulation results of a 3-machine and 9-node system with STATCOM verify that the controller proposed in this paper is effective to power system voltage stability.
