伴隨著機房的擴容，作為備用電源的柴油發電機組容量要求越來越大，需多臺大功率柴油發電機組并網才能滿足負荷的要求，而且機房與實際使用負載間距離也越來越遠，采用傳統的多臺低壓柴油發電機組并聯運行暴露出多項運行和傳輸的缺陷。為了能夠更加安全、可靠地運行，采用高壓機組是一種更好的選擇。
With the expansion of the machine room, the capacity of the diesel generator set as the standby power source is becoming larger and larger. It requires multiple high-power diesel generator sets to be connected to the grid to meet the load requirements. Moreover, the distance between the machine room and the actual load is also getting farther and farther. The traditional parallel operation of multiple low-voltage diesel generator sets exposes many defects in operation and transmission. In order to operate more safely and reliably, it is a better choice to use high voltage units.
高壓機組應用于冶金企業、機場、數據中心等應急備用電源系統,因機組的輸出電壓10kV與原供電系統電壓一致,可直接接入供電系統,省去了大筆供配電系統的設備投資。同時由于機組的輸出電壓高，輸出電流小，在動力傳輸過程功率損失小,適合遠距離輸送。
High-voltage units are used in emergency standby power supply systems such as metallurgical enterprises, airports, data centers, etc. Because the output voltage of the units is 10kV and the voltage of the original power supply system is the same, they can be directly connected to the power supply system, saving a large amount of equipment investment in the power supply and distribution system. At the same time, due to the high output voltage and low output current of the unit, the power loss in the process of power transmission is small, which is suitable for long-distance transmission.

P=1.732×U×I×COSΦ
P=1.732 × U × I × COS Φ
現以2000kW機組為例，功率因素0.8，頻率50Hz 低壓（400V）
Now take 2000kW unit as an example, with power factor of 0.8 and frequency of 50Hz and low voltage (400V)
電流為：I=P/(1.732×U×COSΦ)=2000×103/（1.732×400×0.8）=3609A
Current: I=P/(1.732 × U × COS Φ)= two thousand × 103/（1.732 × four hundred × 0.8）=3609A
