自动调节励磁的组成部件有机端电压互感器、机端电流互感器、励磁变压器﹔励磁装置需要提供以下电流，厂用AC380v、厂用DC220v控制电源厂用DC220v合闸电源;需要提供以下空接点，自动开机自动停机并网(一常开，一常闭)增，减;需要提供以下模拟信号，发电机机端电压100v,发电机机端电流5A，母线电压100V，励磁装置输出以下继电器接点信号;励磁变过流，失磁，励磁装置异常等。

励磁控制、保护及信号回路由灭磁开关，助磁电路、风机、灭磁开关偷跳、励磁变过流、调节器故障、发电机工况异常、电星变送器等组成。在同步发电机发生内部故障时除了必须解列外，还必须灭磁，把转子磁场尽快地减弱到最小程度，保证转子不过的情况下，使灭磁时间尽可能缩短，是灭磁装置的主要功能。根据额定励磁电压的大小可分为线性电阻灭磁和非线性电阻灭磁。

发展

由于采用微机计算机用软件实现的自动调节励磁装置有显著优点，很多国家都在研制和试验用微型机计算机配以相应的外部设备构成的数字自动调节励磁装置，这种调节装置将能实现自适应最佳调节。

Components of automatic excitation regulation organic end voltage transformer, machine end current transformer, excitation transformer; The excitation device needs to provide the following current, factory AC380v, factory DC220v control power supply factory DC220v closing power supply; Need to provide the following air contact, automatic start automatic stop grid (a normal open, a normal close) increase, decrease; The following analog signals need to be provided, the generator terminal voltage is 100v, the generator terminal current is 5A, the bus voltage is 100V, and the excitation device outputs the following relay contact signals; Excitation variation overcurrent, loss of excitation, excitation device abnormality, etc.

Excitation control, protection and signal circuit are composed of magnetic switch, magnetic circuit, fan, magnetic switch skip, excitation change overcurrent, regulator fault, generator abnormal condition, electric star transmitter, etc. In addition to the internal failure of the synchronous generator must be disassembled, but also must be out of the magnetic field, the rotor magnetic field as soon as possible to weaken to the minimum degree, to ensure that the rotor is not the case, so that the magnetic time as short as possible, is the main function of the magnetic device. According to the rated excitation voltage, it can be divided into linear resistance and nonlinear resistance.

develop

Because of the obvious advantages of automatic regulation excitation device realized by microcomputer software, many countries are developing and testing digital automatic regulation excitation device composed of microcomputer computer with corresponding external equipment, which can realize adaptive optimal regulation.
