ABB SDCS-FIS-3A DCF803-0035励磁板是一款由ABB公司生产的励磁单元，也称为励磁板。DCF803-0035是其主要型号，被广泛应用于各种工业驱动系统中，特别是在电力驱动系统中，如电机、发电机等。

该励磁板的主要参数包括额定电压为3x500V AC，最大电流为35A，并且支持扩展/三相电源供电模式。这些特性使得DCF803-0035励磁板能够适应不同的工作环境和负载需求。

在水电站发电机中，励磁系统作为重要组成部分，承担着调节发电机的出口电压和机组无功功率的任务。励磁板是励磁系统的关键组成部分之一，其稳定运行对于保障电力系统的稳定和安全至关重要。

通常，励磁调节是根据设定好的调节准则，通过采集接受的信号最终实现控制励磁单元的输出。对于水电机组来说，根据机组的容量不同，其励磁方式也不同。容量大于500kW的机组励磁方式采用自并励可控硅励磁，小于500kW的水电机组励磁方式为双绕组电抗器分流自复励方式，投产较早的水电机组励磁方式为永磁副励磁机和交流侧串联相复励方式。

在正常运行情况下，励磁调节器采用自动电压调节（AVR）控制方式，通过调节PID调节器的输出来改变发电机的励磁电流，从而实现发电机端电压的稳定。

The ABB SDSC-FIS-3A DCF803-0035 excitation board is an excitation unit, also known as an excitation board, manufactured by ABB. DCF803-0035 is its main model, which is widely used in various industrial drive systems, especially in electric drive systems, such as motors, generators, etc.

The main parameters of the exciter include a rated voltage of 3x500V AC, a maximum current of 35A, and support for extended/three-phase power supply mode. These characteristics enable the DCF803-0035 exciter to adapt to different working environments and load requirements.

The excitation system, as an important part in the generator of hydropower station, assumes the task of regulating the output voltage and reactive power of the generator. Excitation board is one of the key components of excitation system, and its stable operation is very important to ensure the stability and safety of power system.

Generally, excitation regulation is based on the set regulation criteria, by collecting the accepted signal to finally control the output of the excitation unit. For hydropower units, according to the capacity of the unit, its excitation method is also different. The excitation mode of the unit with a capacity greater than 500kW is self-shunt SCR excitation, the excitation mode of the hydropower unit with a capacity less than 500kW is double-winding reactor shunt self-compound excitation, and the excitation mode of the hydropower unit that was put into operation earlier is the permanent magnet secondary exciter and the series phase compound mode of the AC side.

Under normal operation, the excitation regulator adopts the automatic voltage regulation (AVR) control mode to change the excitation current of the generator by adjusting the output of the PID regulator, so as to realize the stability of the generator terminal voltage.
