众所周知,大型同步机的启动一直是个相当复题,如果采用通常的异步启动方法,依靠阻尼行启动,那么它对电力系统的扰动将十分严重,一般许的。如果用减压启动,不但需要很大的电抗器,而且启动绕组发热严重,很难保证安全运行。如果用专门的启动电机,由于需要同轴安装,使主机轴变长,在 It is well-known that starting a large synchronous machine has always been quite a problem. If the usual asynchronous starting method is used and the damping line is started, its disturbance to the power system will be very serious, generally. If you start with decompression, not only requires a large reactor, and start winding serious heating, it is difficult to ensure safe operation. If you use a special starter motor, due to the need for coaxial installation, make the host shaft longer, in
