在柴油发电机组并机时,发动机速度与发电机电压的调整可以通过并机控制器的直流电压输出来控制,以达到分配发电机组功率的目的。不同发电机组的GOV(调速器)与AVR(调压器)控制电压是不同的,必须要正确设置并机控制器GOV、AVR的SW1与SW2与之匹配。

SW1也称为中心电压,由并机控制器GOV和AVR接口输出,中心电压为发动机转速和发电机电压在标准值或者额定值时的调节电压。SW1设置值和电压之间的对应关系为:



例如:发电机组调速板为GAC5500,中心电压为4.5V,控制器GOV的SW1需要设置为9。

发电机组调压板为RS440,中心电压为0V,控制器AVR的SW2需要设置为0。

SW2也称为调节范围,是对中心电压输出的上限和下限值作出限制,以限制并机控制器对发电机组的转速和电压的调整范围。SW2设置值和电压之间的对应关系为:



例如:GOV和AVR的SW2设置为0,则GOV和AVR输出电压偏置范围电压值±0.5V,当GOV中心电压为4.5V时,GOV调节输出范围为4~5V,当AVR中心电压为0V时,AVR调节输出为-0.5~0.5V。



SmartGen Parallel Gensets Controller GOV/AVR Settings


When the diesel genset parallel with genset, the adjustment of the engine speed and the generator voltage can be controlled by parallel controller's DC voltage output to distribute the genset power. The controlled voltage of GOV and AVR from different gensets are not same. It is important to set up the parallel controller GOV, AVR's SW1 and SW2 to match up the genset in right way.


SW1 is also called center voltage, which is outputted by GOV and AVR interface of parallel controller. SW1 is adjustment voltage when the engine rotation speed and the generator voltage are standard values or rated values. There is the corresponding relationship of SW1 setting values and voltages:


For example: With the genset speed regulation plate is GAC5500 and center voltage is 4.5V, SW1 of controller GOV should be set as 9. With the genset voltage regulation plate is RS440 and center voltage is 0V, SW2 of controller AVR should be set as 0. 


SW2 is also called adjusting range, which restricts the upper and lower limits of center voltage output to limit the adjustment range from parallel controller to the genset rotation speed and the voltage. There is the corresponding relationship of SW2 setting values and voltages:


For example: With SW2 of GOV and AVR is set as 0, the output voltage bias range values of GOV and AVR is±0.5V. When the center voltage of GOV is 4.5V, the adjusting output range of GOV is 4~5V. When the center voltage of AVR is 0V, the adjusting output range of AVR is -0.5~0.5V.
