研究了超导磁储能系统中通过控制功率变换器的发射角实现同步发电机的稳定。设计了一种最优的射击角控制策略，以在最短时间内消除瞬变。考虑了同步发电机、其调速器和励磁系统以及与发电机终端相连的SMES系统的非线性模型。在保持系统动力学非线性的前提下，导出了最佳射击角控制。数字仿真结果表明，该策略能有效地控制系统的慢增长和初摆不稳定性。>
Stabilization of a synchronous generator through control of firing angle of the power converters in superconducting magnetic energy storage (SMES) systems is considered. An optimum strategy of the firing angle control is designed so as to eliminate the transients in minimum time. A nonlinear model of a synchronous generator, its governor and exciter systems, and an SMES system connected to the generator terminal is considered. The optimum firing angle control is derived retaining the nonlinearities of the system dynamics. Digital simulation results indicate that the proposed strategy controls the slowly growing as well as first swing instabilities very effectively. >
