【摘要】 基于哈密顿系统理论，将含有ＳＴＡＴＣＯＭ的简单电力系统表示为标准的哈密顿系统，推导了该系统的哈密顿函数，并证明了所得到的哈密顿函数可作为判断系统稳定性的Ｌｙａｐｕｎｏｖ画数。根据该函数，提出了ＳＴＡＴＣＯＭ控制的电力系统的暂态稳定分析新方法。对含有ＳＴＡＴＣＯＭ控制的简单电力系统的数值仿真结果证实了这一方法的有效性。更多还原

【Abstract】 Based on the Hamiltonian system theory. a simplified power system with static synchronous compensator (STATCOM) is expressed as a standard Hamiltonian system at first. Then the Hamiltonian function of this system is derived, and it is proved to be a candidate Lyapunov function for stability analysis. So by this function, a novel transient stability analytical method is proposed for the controlled power system with STATCOM. Simulation results of the simplified power system with STATCOM verify the correctness of the proposed method.
