| 摘 要： | 针对高压直流输电系统(HVDC)与发电机励磁协调控制问题,建立了HVDC和发电机励磁综合控制模型,采用微分几何变换法进行部分线性化获得了与原系统相同定性行为的线性系统.基于该线性化模型设计了控制方案并对控制器进行仿真.仿真结果表明,验证了控制器的有效性、可靠性,易于实际应用.

| Abstract: | A comprehensive control strategy for AC/DC power system and generator excitation is deduced in this paper.First,a model that can describe the dynamic characteristics of both AC/DC system and generator excitation is established.Then,this non-affine nonlinear model is linearized by transformation due to differential geometry theory.Last,a control strategy is introduced and a linear controller is designed.It is shown that through the firing angle control of the rectifier and converter,the stability of system c... |
