基于实用稳定域的次同步振荡阻尼控制器设计
Subsynchronous Damping Controller Design Based on Practical Stability Region
摘要
Abstract
Along with the wide applications of nonlinear power device such as high voltage direct current transmission and flexible AC transmission system, power grid operation mode is flexible and changeable. Traditional subsynchronous oscillation (SSO) damping controllers designed by point-to-point method face the problem of poor robustness. In order to improve the robustness of SSO damping controllers, a design method for damping controllers based on practical subsynchronous stability region was suggested. A new type of stability boundary was defined by critical damping level. The new-type boundary was used to construct the practical subsynchronous stability region, which was employed directly in optimizing the parameters of damping controllers. The impact of operational parameters on SSO in a power system including a thyristor-controlled series capacitor (TCSC) was studied,and the conducting angle of TCSC was found to be the leading factor impacting the damping of SSO mode. Aiming at the best subsynchronous stability region of conducting angle of TCSC, the parameters of supplementary excitation damping controller (SEDC) is optimized with genetic algorithm. The results show that SEDC designed by this method can greatly increase the safety operating range of TCSC.关键词
