针对具有静止同步补偿装置(static synchronous compensator,STATCOM)的单机无穷大系统,研究了发电机励磁无源协调控制,采用耗散性和无源性理论的反步设计方法构造了系统的存储函数。根据协调无源性的特点,得到了STATCOM与发电机励磁协调控制器,使得系统在STATCOM和励磁的共同作用下,保持系统功角和电压的稳定。设计过程充分利用了系统的非线性性质,不采用任何线性化的处理,保证了所提出的控制律在非线性系统中的适用性,并有效地提高了电力系统的暂态稳定性能。仿真结果证实了该控制律的有效性和正确性。
Aiming at the single machine infinite system with static synchronous compensator (STATCOM), the generator excitation and passive coordination control is studied. The storage function of the system is constructed by the backstepping method of dissipative and passive theory. According to the coordination of passive characteristics, STATCOM and generator excitation coordination controller are obtained, so that the system maintains the system power angle and voltage stability under the combined action of STATCOM and excitation. The design process takes full advantage of the nonlinear nature of the system, without any linearization process to ensure the applicability of the proposed control law in nonlinear systems and effectively improve the transient stability of the power system. The simulation results confirm the validity and correctness of the control law.
