The structure and principle of permanent magnet machine and exciter are the same as that of generator, both of which are wire cutting magnetic force line. In other words, there are three generators of different sizes hidden in a complete generator.

①  當發電機轉動時，永磁機裏的磁場轉動，定子線圈中發出相對較弱的三相交流電，送往調壓模塊，作為勵磁的電源。

① When the generator rotates, the magnetic field in the permanent magnet machine rotates, and the relatively weak three-phase alternating current from the stator coil is sent to the voltage regulating module as the excitation power supply.

②  勵磁電源經過調壓模塊的整流後，變成直流，送進勵磁機定子，勵磁機開始發電。

② After rectifying the voltage regulating module, the excitation power supply becomes DC, which is sent to the exciter stator, and the exciter starts to generate electricity.

③  勵磁機發出的交流電經過一套整流模塊（旋轉二極管）進行整流，送往發電機主轉子。這部分直流電就是所謂的“勵磁電流”。

③ The AC power from the exciter is rectified by a set of rectifier module (rotating diode) and sent to the main rotor of the generator. This part of direct current is called "excitation current".

④  主轉子建立磁場，從主定子輸出更終的三相交流電。

④ The main rotor establishes the magnetic field and outputs the final three-phase alternating current from the main stator.

相對於火電水電等大型機組，內燃機的這種勵磁係統顯得極為簡陋，相關參數和保護也比較少，一般隻能看到勵磁電壓和勵磁電流兩個參數。有的係統裏甚至這兩個數據都不對外送，想看勵磁電壓勵磁電流，請連上電腦。

Compared with large units such as thermal power, hydropower and other large-scale units, the excitation system of internal combustion engine is very simple, and the relevant parameters and protection are relatively small. Generally, only two parameters of excitation voltage and excitation current can be seen. In some systems, even these two data are not sent out. If you want to see the excitation voltage and current, please connect to the computer.

有功和無功控製

Active and reactive power control

發電機的有功功率和無功功率是分開控製的，是完全不同的兩種方式。

The active power and reactive power of the generator are controlled separately, which are two completely different ways.

有功功率對應的是發動機的軸輸出功率，有功功率提高，需要把發動機油門開大，耗氣/油量上升。這部分由發動機的調速係統控製，和發電機無關。

The active power corresponds to the shaft output power of the engine. If the active power is increased, the engine throttle should be opened up, and the gas / fuel consumption will increase. This part is controlled by the speed control system of the engine and has nothing to do with the generator.

無功功率對應的是主轉子磁場，無功功率提高，需要加大主轉子磁場強度，加大勵磁電壓。這部分由發電機的調壓係統控製，也就是調壓模塊，和發動機無關。

The reactive power corresponds to the magnetic field of the main rotor. To improve the reactive power, it is necessary to increase the magnetic field strength of the main rotor and increase the excitation voltage. This part is controlled by the voltage regulating system of the generator, that is, the voltage regulating module, and has nothing to do with the engine.

雖然有功和無功在控製上是分開的，但在分布式項目中，兩者都是成比例的增長或減小，這是因為分布式項目通常采用定功率因數運行的模式運行，有功和無功的比例被鎖定了，當好色TV下载安装人為去調節有功功率時，無功功率會自動的跟著調節。

Although active power and reactive power are separated in control, they both increase or decrease proportionally in distributed projects. This is because distributed projects usually operate in the mode of fixed power factor operation, and the proportion of active and reactive power is locked. When we artificially adjust the active power, reactive power will automatically follow the regulation.
