| 摘 要： | 验证了晶闸管控制的串联电容器（SVCs）和静止无功补偿器（SVCs）在提高电力系统动态稳定性中的作用，分析了适合于功角稳定性动态仿真研究的模型。运用能量函数法，推导出一个可以抑制功角振荡的控制策略。通过使用该控制策略，SVCs和TCSCs都能够增强系统对功角摇摆的抑制而不会影响其他功率振荡阻尼（POD）设备的作用。最后，通过一个简单的双机系统来证明这种控制策略的有效性。

| Abstract: | The improvement of power system dynamics by use of thyristor controlled series capacitors(TCSCs)and static var systems(SVCs)is examined.Models suitable for dynamic simulation for studying angle stability are analyzed.Using an energy function method,a control strategy for damping of angle oscillations is derived.Using this control strategy, both TCSC and SVC will contribute to the damping of power swings without deteriorating the effect of the other power oscillation damping(POD)devices.At last,the effectiveness of the control strategy are demonstrated at a simple two- machine power system. |
