Real-time computing method for equivalent capacity of SEDC (supplementary excitation damping controller) and STATCOM (static synchronous compensator)

Abstract

本发明涉及一种励磁阻尼控制器与静止同步补偿器等价容量的实时计算方法。所述方法依序包括以下步骤:计算SEDC的电气阻尼;计算STATCOM的电气阻尼;基于SEDC与STATCOM的电气阻尼整定其控制器增益关系;应用整定的增益关系对SEDC与STATCOM的控制器进行整定,在此基础上,计算在相同扰动下,SEDC与STATCOM的等价容量。
The invention relates to a real-time computing method for equivalent capacity of an SEDC (supplementary excitation damping controller) and an STATCOM (static synchronous compensator). The real-time computing method includes the following steps of computing electrical damping of the SEDC; computing electrical damping of the STATCOM; setting gain relationship of controllers of the SEDC and the STATCOM according to the electrical damping of the SEDC and the STATCOM; subjecting the controllers of the SEDC and the STATCOM to setting according to the set gain relationship, and then computing the equivalent capacity of the SEDC and the STATCOM under the same disturbance.
