ABB SNAT603CNT
是一种励磁系统，被定义为通过磁场绕组中的电流产生磁通量的系统。这种系统主要应用在同步电机转子绕组，为其提供必要的励磁电流。
ABB SNAT603CNT励磁系统的可靠性、控制简单性、易维护性、稳定性和快速瞬态响应都是其主要优点。所需的励磁量取决于负载电流、负载功率因数以及机器速度，当负载电流大时系统需要的励磁更多，转速越低，系统的功率因数就会变得滞后。
ABB SNAT603CNT励磁系统是一个单独的单元，每个交流发电机都有一个发电机形式的励磁机。集中励磁系统有两个或多个为母线供电的励磁机，这种系统设计较为便宜，但是系统中的故障可能会对发电厂中的交流发电机产生不利影响。
It is an excitation system defined as a system that generates magnetic flux through the current in the magnetic field winding. This system is mainly used in synchronous motor rotor windings to provide necessary excitation current.
The reliability, simplicity of control, ease of maintenance, stability, and fast transient response of the ABB SNAT603CNT excitation system are its main advantages. The required excitation amount depends on the load current, load power factor, and machine speed. When the load current is high, the system requires more excitation, and the lower the speed, the power factor of the system will become lagging.
The ABB SNAT603CNT excitation system is a separate unit, with each AC generator having an exciter in the form of a generator. The centralized excitation system has two or more exciters that supply power to the busbar. This system design is relatively inexpensive, but faults in the system may have adverse effects on the AC generator in the power plant.
