ABB SDCS-FIS-3A DCF803-0035勵(lì)磁板是一款由ABB公司生產(chǎn)的勵(lì)磁單元，也稱為勵(lì)磁板。DCF803-0035是其主要型號(hào)，被廣泛應(yīng)用于各種工業(yè)驅(qū)動(dòng)系統(tǒng)中，特別是在電力驅(qū)動(dòng)系統(tǒng)中，如電機(jī)、發(fā)電機(jī)等。

該勵(lì)磁板的主要參數(shù)包括額定電壓為3x500V AC，最大電流為35A，并且支持?jǐn)U展/三相電源供電模式。這些特性使得DCF803-0035勵(lì)磁板能夠適應(yīng)不同的工作環(huán)境和負(fù)載需求。

在水電站發(fā)電機(jī)中，勵(lì)磁系統(tǒng)作為重要組成部分，承擔(dān)著調(diào)節(jié)發(fā)電機(jī)的出口電壓和機(jī)組無(wú)功功率的任務(wù)。勵(lì)磁板是勵(lì)磁系統(tǒng)的關(guān)鍵組成部分之一，其穩(wěn)定運(yùn)行對(duì)于保障電力系統(tǒng)的穩(wěn)定和安全至關(guān)重要。

通常，勵(lì)磁調(diào)節(jié)是根據(jù)設(shè)定好的調(diào)節(jié)準(zhǔn)則，通過(guò)采集接受的信號(hào)最終實(shí)現(xiàn)控制勵(lì)磁單元的輸出。對(duì)于水電機(jī)組來(lái)說(shuō)，根據(jù)機(jī)組的容量不同，其勵(lì)磁方式也不同。容量大于500kW的機(jī)組勵(lì)磁方式采用自并勵(lì)可控硅勵(lì)磁，小于500kW的水電機(jī)組勵(lì)磁方式為雙繞組電抗器分流自復(fù)勵(lì)方式，投產(chǎn)較早的水電機(jī)組勵(lì)磁方式為永磁副勵(lì)磁機(jī)和交流側(cè)串聯(lián)相復(fù)勵(lì)方式。

在正常運(yùn)行情況下，勵(lì)磁調(diào)節(jié)器采用自動(dòng)電壓調(diào)節(jié)（AVR）控制方式，通過(guò)調(diào)節(jié)PID調(diào)節(jié)器的輸出來(lái)改變發(fā)電機(jī)的勵(lì)磁電流，從而實(shí)現(xiàn)發(fā)電機(jī)端電壓的穩(wěn)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.
