【功能描述】

ABB-GFD233A靜態(tài)勵磁系統(tǒng)的主要作用是提供可調(diào)節(jié)的直流電流來激勵同步發(fā)電機(jī)的轉(zhuǎn)子，從而實現(xiàn)對發(fā)電機(jī)輸出電壓的精確控制。同時，它還可以增強(qiáng)并列運行發(fā)電機(jī)間無功功率分配的穩(wěn)定性和發(fā)電機(jī)的運行穩(wěn)定性。

靜態(tài)勵磁系統(tǒng)是一種勵磁系統(tǒng)，其原理是通過控制電壓和電流，實現(xiàn)對發(fā)電機(jī)的勵磁電流的調(diào)節(jié)。在發(fā)電機(jī)中，勵磁系統(tǒng)的作用是產(chǎn)生磁場，使發(fā)電機(jī)能夠產(chǎn)生電流。而靜態(tài)勵磁系統(tǒng)則是通過調(diào)節(jié)勵磁電流的大小和方向，來控制發(fā)電機(jī)的輸出電壓和頻率，從而實現(xiàn)對電力系統(tǒng)的調(diào)節(jié)。

靜態(tài)勵磁系統(tǒng)通常由勵磁變壓器、勵磁電源和控制裝置等組成。其中，勵磁變壓器主要負(fù)責(zé)將交流電轉(zhuǎn)換為直流電，為發(fā)電機(jī)提供勵磁電流；勵磁電源則負(fù)責(zé)提供勵磁電流；控制裝置則通過對勵磁電流的實時監(jiān)測和控制，確保發(fā)電機(jī)的穩(wěn)定運行。

與傳統(tǒng)的機(jī)械式勵磁系統(tǒng)相比，靜態(tài)勵磁系統(tǒng)具有調(diào)節(jié)精度高、響應(yīng)速度快、穩(wěn)定性好等優(yōu)點。因此，在現(xiàn)代化的電力系統(tǒng)控制中得到廣泛應(yīng)用。

【英文介紹】

The main role of the ABB-GFD233A static excitation system is to provide an adjustable DC current to excite the rotor of the synchronous generator, thus achieving precise control of the output voltage of the generator. At the same time, it can also enhance the stability of reactive power distribution between parallel running generators and the running stability of generators.

Static excitation system is a kind of excitation system, its principle is to control the voltage and current to achieve the regulation of the excitation current of the generator. In a generator, the role of the excitation system is to generate a magnetic field that enables the generator to generate current. The static excitation system is to control the output voltage and frequency of the generator by adjusting the size and direction of the excitation current, so as to realize the regulation of the power system.

Static excitation system is usually composed of excitation transformer, excitation power supply and control device. Among them, the excitation transformer is mainly responsible for converting alternating current to direct current to provide excitation current for the generator; Excitation power supply is responsible for providing excitation current; The control device ensures the stable operation of the generator by monitoring and controlling the excitation current in real time.

Compared with the traditional mechanical excitation system, the static excitation system has the advantages of high adjustment precision, fast response speed and good stability. Therefore, it has been widely used in modern power system control.
