| 摘 要： | 研究在发电机与母线之间装设移相变压器，在暂态过程中，利用移相器控制发电机功角，改变发电机输出电磁功率，增加阻尼转矩，防止机组失步，并利用李雅普诺夫直接法评价系统稳定性。仿真结果表明，本控制方案有效地改善了电力系统运行的暂态稳定性。

| Abstract: | This paper studies the installation of a phase shift transformer between generators and buses,uses the phase shifter to control the power-torque angel, change the output magnetitute power of the generator, increase the damping rotor-moment, prevent the unstability of the power units. The Lyapunov's direct method is usde to evalute the stability of the system.Simulation results show that this scheme can improve effectively the transient stabilisty of the electric power system. |
