摘要:
为了给静止无功补偿器(SVC)阻尼特性的研究提供更为严谨的理论依据,建立了考虑发电机阻尼绕组作用的单机-SVC-无穷大系统线性化直观模型(扩展模型),并针对不同情况计算系统的特征根,讨论影响SVC阻尼作用大小的有关因素.研究结果表明,当SVC有阻尼控制时,能向电力系统提供正阻尼;当SVC仅有电压控制时,对系统阻尼的影响很小;而当SVC同时有电压和阻尼控制时,增大电压控制增益,反而会削弱阻尼控制的作用;从提高系统阻尼的角度考虑,SVC的最佳安装地点在输电线路中点附近.
Abstract:

In order to provide a more rigorous theoretical basis for the study of the damping characteristics of static reactive power compensator (SVC), an intuitive linearization model (extended model) of stand-alone svc-infinity system considering the damping winding of generators is established, and the characteristic roots of the system are calculated for different situations, and the relevant factors affecting the magnitude of SVC damping are discussed. The results show that when SVC has damping control, it can provide positive damping to the power system. When SVC only has voltage control, it has little effect on system damping; When SVC has both voltage and damping control, increasing the voltage control gain will weaken the role of damping control; From the perspective of improving system damping, the best installation location for SVC is near the midpoint of the transmission line.
