| 摘 要： | 提出了一种新的应用STATCOM装置改善发电机轴系扭矩的办法，与以往研究相比，在引入STATCOM控制装置后的IEEE第一基准模型中，基于扫频．复转矩系数法，根据复转矩系数法的基本原理，得出了发电机机械复转矩系数和考虑STATCOM装置时的电气复转矩系数表达式，给出了二者之间的定量关系，以此为基础研究了应用STATCOM改善发电机轴系间扭矩的控制策略，并设计了相应的控制器。仿真结果证明，使用STATCOM进行无功补偿的同时可以阻尼电力系统次同步谐振现象，有一定实用价值。

| Abstract: | A novel scheme is proposed to ameliorate generator shaft torsional torques with STATCOM. Comparing to the former researches, for the IEEE first benchmark model with a STATCOM control device, the mechanical complex torque coefficient and the electrical complex torque coefficient of the system are derived and a quantitative relationship between them is also attained on the theoretical basis of complex torque coefficient. Based on it, control strategy is presented to ameliorate generator shaft torsional torque... |
