伴随着机房的扩容，作为备用电源的柴油发电机组容量要求越来越大，需多台大功率柴油发电机组并网才能满足负荷的要求，而且机房与实际使用负载间距离也越来越远，采用传统的多台低压柴油发电机组并联运行暴露出多项运行和传输的缺陷。为了能够更加安全、可靠地运行，采用高压机组是一种更好的选择。
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.
高压机组应用于冶金企业、机场、数据中心等应急备用电源系统,因机组的输出电压10kV与原供电系统电压一致,可直接接入供电系统,省去了大笔供配电系统的设备投资。同时由于机组的输出电压高，输出电流小，在动力传输过程功率损失小,适合远距离输送。
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.
