燃气发电机组励磁系统的介绍

永磁机、励磁机的结构和原理和发电机是一样的,都是导线切割磁力线。也就是说,在一台完整的发电机里,其实暗藏着三台大小不同的发电机。
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  当发电机转动时,永磁机里的磁场转动,定子线圈中发出相对较弱的三相交流电,送往调压模块,作为励磁的电源。
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  励磁电源经过调压模块的整流后,变成直流,送进励磁机定子,励磁机开始发电。
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  励磁机发出的交流电经过一套整流模块(旋转二极管)进行整流,送往发电机主转子。这部分直流电就是所谓的“励磁电流”。
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  主转子建立磁场,从主定子输出更终的三相交流电。
④ The main rotor establishes the magnetic field and outputs the final three-phase alternating current from the main stator.
相对于火电水电等大型机组,内燃机的这种励磁系统显得极为简陋,相关参数和保护也比较少,一般只能看到励磁电压和励磁电流两个参数。有的系统里甚至这两个数据都不对外送,想看励磁电压励磁电流,请连上电脑。
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.
有功和无功控制
Active and reactive power control
发电机的有功功率和无功功率是分开控制的,是完全不同的两种方式。
The active power and reactive power of the generator are controlled separately, which are two completely different ways.
有功功率对应的是发动机的轴输出功率,有功功率提高,需要把发动机油门开大,耗气/油量上升。这部分由发动机的调速系统控制,和发电机无关。
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.
无功功率对应的是主转子磁场,无功功率提高,需要加大主转子磁场强度,加大励磁电压。这部分由发电机的调压系统控制,也就是调压模块,和发动机无关。
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.
虽然有功和无功在控制上是分开的,但在分布式项目中,两者都是成比例的增长或减小,这是因为分布式项目通常采用定功率因数运行的模式运行,有功和无功的比例被锁定了,当我们人为去调节有功功率时,无功功率会自动的跟着调节。
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.
