3.
According to its characteristic and scheme, a frequency control loop based on the model of DFIG based wind turbines is proposed and it is implemented in the simulation package of DIgSILENT/PowerFactory.
文中以双馈变速风电机组模型为基础,根据双馈变速风电机组控制特点和控制过程,在电力系统仿真软件DIgSILENT/PowerFactory中增加了频率控制环节,在系统频率变化时,双馈变速风电机组通过释放或者吸收转子中的一部分动能,相应增加或者减少有功出力,实现了风电机组的频率控制。
补充资料:音叉
1.用钢材制成的发声仪器。形状像叉子,用小木槌敲打发出声音。音叉的长短厚薄不同,能产生各种音高的声音,可以用来调整乐器和帮助歌唱者定出音高。
