中文摘要:

本文首先提出了一种多频段稳定域的方法用于优化设计机侧/网侧多通道附加阻尼控制器。在此基础上，以TCSC导通角组成的多频段稳定域最大为优化目标建立协调优化模型，并采用遗传算法对其进行求解，得到能最大程度提高系统阻尼的控制器参数。特征值计算和时域仿真表明，经过协调优化的阻尼控制器能有效地抑制包括低频振荡与次同步振荡在内的多频段振荡。

英文摘要:

In this paper, a multiband stable domain method for designing and optimizing the machine/grid-side multi-channel supplementary damping controllers (MSDC) is proposed. On this basis, considering the maximized multi-band stability domain composed of TCSC conduction angles as the optimization objective and an optimization model is established. Furthermore, genetic algorithm is used to solve optimization model to obtain controller parameters that can maximize damping of system. Eigenvalue calculation and time-domain simulation show that the coordinative optimized damping controller can effectively suppress multi-band oscillations including low-frequency oscillation and subsynchronous oscillation.
