| 摘 要： | 提出一种优化统一潮流控制器(UPFC)的附加阻尼控制器参数的新方法.这种方法以表征系统机电振荡模式的发电机转子角速度作为优化的目标函数,使用轨迹灵敏度技术计算目标函数对阻尼控制器参数的灵敏度,并采用共轭梯度法进行参数优化.在新英格兰测试系统上进行的仿真算例说明了使用该方法所设计的UPFC阻尼控制器可有效抑制系统低频振荡.

| Abstract: | A new approach for optimizing the parameters of supplementary damping controller of the UPFC is proposed. In this approach, the sum of generator speed is utilized as the objective function. Trajectory sensitivity analysis is performed to obtain the sensitivity of the objective function to the controller parameters and conjugate gradient method is adopted to optimize the parameters using the sensitivity obtained. Simulation results on the New England test system show that the suggested method can damp low frequency oscillation effectively. |
