应用SMES改善发电机轴系扭矩的研究

Research on Amelioration of Generator Shaft Torsional Torque with SMES

提出了一种应用超导磁储能(SMES)装置改善发电机轴系扭矩的办法,以IEEE第一基准模型为研究对象,根据复转矩系数法的基本原理,得到发电机机械复转矩系数,并考虑SMES装置的电气复转矩系数的表达式,给出了二者之间的定量关系式,以此为依据研究了应用SMES改善发电机轴系扭矩的控制策略,并设计了相应的控制器。仿真结果表明,使用SMES进行无功补偿的同时可以起到阻尼发电机轴系间扭振的作用,具有一定的现实意义。

A novel scheme is proposed to ameliorate generator shaft torsional torque with SMES. Takes IEEE first benchmark model as a SMES 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. The control strategy is presented to ameliorate generator shaft torsional torque with SMES. The simulation results indicate that, SMES focusings on reactive power compensating of resistance power system and has practical value.
