摘　　要：针对发电机励磁和相间功率控制器(IPC)对电力系统稳定性的影响,提出了通过相间功率控制器和发电机励磁系统共同作用提高系统暂态稳定性。基于单机无穷大系统的非线性模型,建立了包含励磁系统参数和相间功率控制器控制参数的状态空间方程,并基于最优变目标控制(OVAC)策略,可以得出以励磁系统为基础加以IPC协调的控制规律,通过仿真分析,可以验证该策略能够有效提高系统的暂态稳定性。The influence of generator excitation and interphase power controller( IPC) on the stability of power system is studied respectively. It is proposed that the interphase power controller and generator excitation system act together to improve the transient stability of the system. Based on the nonlinear model of single machine infinite bus system, the state space equation including excitation system parameters and interphase power controller control parameters is established. Based on the optimal variable target control( OVAC) strategy, the control law coordinated by IPC based on excitation system can be obtained. Through simulation analysis, it can be verified that the strategy can effectively improve the transient stability of the system.
