| 摘 要： | 提出了一种基于时域仿真的可控串联电容补偿(TCSC)及其附加阻尼控制器的参数优化方案。该方案以表征系统振荡相对动能的发电机角速度的平方最小为目标函数,通过轨迹灵敏度仿真得到目标函数的梯度信息,再应用共轭梯度法优化TCSC阻尼控制器参数。数字仿真表明,在发电机振荡模式和区域间振荡模式下,可有效提高大区域系统的动态稳定性。

| Abstract: | The paper presents a parameter optimization scheme of TCSC and its additional damping controller based on time domain simulation. The scheme takes the square of generator angular velocity as the object function. The gradient information of the object function is got through trajectory sensitivity simulation. The parameters of TCSC damping controllers are optimized using conjugate gradient method. Simulations show that the dynamic stability of wide area systems is effectively increased in generator oscillation mode and inter zone oscillation mode. |
