| ITEM | FEATURE | LOW-VOLTAGE GENSET | HIGH-VOLTAGE GENSET |
| 1 | Capacity | Multiple gensets can be run in parallel. | Multiple gensets can run in parallel, and the machine room can be built in a centralized manner. |
| 2 | Power Transmission | Can transmit power over short distances | Can transmit power over long distances |
| 3 | Converying Distance | has a large line loss in power transmission and distribution | In power transmission and distribution, the line loss is small, and there is no transmission heating problem |
| 4 | Cost | The initial investment of the equipment is small, the maintenance cost is low, and the low capacity and short distance have great advantages. The cost of high capacity and long distance use will be much higher than that of the high pressure unit | The initial equipment investment is relatively large, and the maintenance cost is low. It has obvious advantages for large-capacity and long-distance power transmission and distribution, and the supporting investment cost is low. |
| 5 | Operation & Maintenance | The operation and use are relatively simple, and the requirements for operators and users are relatively low. | The operation and use are relatively complicated, and the requirements for operators and users are relatively high, and they must have the corresponding high-voltage operation qualifications to operate. |
| 6 | Specifications | The configuration is relatively simple | The configuration is more complicated, especially in terms of generators and output distribution cabinets. |
| 7 | Safety | High safety performance, relatively mature technology, and low technical threshold | The safety performance is high, the technology is relatively mature, and the technical threshold is high. |
| 8 | Growing Trend | The low-power section maintains the traditional market, and the high-power section tends to be replaced by high-voltage systems | The use of high-voltage systems is the current world trend, and the demand is gradually increasing. |
With the expansion of the machine room, the capacity of diesel generator sets as a backup power source is getting larger and larger, and multiple high-power diesel generator sets need to be connected to the grid to meet the load requirements, and the distance between the machine room and the actual load is getting farther and farther. The traditional parallel operation of multiple low-voltage diesel generator sets exposes a number of defects in operation and transmission. In order to be able to operate more safely and reliably, it is a better choice to use a high-pressure unit.
Based on the application characteristics of the aforementioned high and low voltage diesel generators, in scenarios where there is a demand for large capacity and long power transmission distances, high-voltage diesel generator sets exhibit significant advantages such as high capacity, long-distance power supply, centralized construction of power stations, strong reliability, and a simpler supporting distribution system. It is an inevitable trend for the selection and application of large-capacity generator sets. High-voltage diesel generator sets have already been extensively utilized in sectors such as banking, data centers, metallurgy, and civil aviation.
