Construction sites are located in remote areas where the municipal power supply cannot reach, so diesel generators need to be used for power supply. The diesel generators need to supply power for both production and daily life, and they operate continuously for 24 hours without shutting down. When supplying power for production, the diesel generators operate with relatively high efficiency. However, when supplying power for daily life, the load rate of the diesel generators is low, resulting in low efficiency and high fuel consumption.
