Application of Diesel Battery Hybrid Smart Power Station in Pile Driving for Highway Pavement

Application of Diesel-Storage Hybrid Smart Power Station in Pile Driving for Highway Pavement

Project Overview:

This case is based on a highway project in Guangzhou. Pile driving for highway pavement is an outdoor mobile construction scenario with no stable municipal power grid on site. The conventional power supply solution relies purely on diesel generators. This project adopts a diesel-storage hybrid smart power station (diesel generator + energy storage hybrid) to replace the traditional pure diesel power generation, delivering continuous power for pavement pile driving equipment.

Power Station Configuration: 2 sets of 360kW diesel generators + 2 sets of energy storage systems

Basic Power Load Data:

Average load power: 552.5kW

Daily operating hours: 12h, daily power consumption: 6,630 kWh

Monthly working days: 28 days, monthly power consumption: 185,600 kWh

Construction period: 12 months, total power consumption: 2,227,700 kWh

Fuel Cost Comparison:

Cost Savings: With the same power consumption, the smart power station saves 1.678 million RMB in fuel cost compared with conventional diesel generation.

Advantages for Pile Driving Scenarios:

• Significant fuel reductionThe energy storage system bears peak loads, so diesel generators do not need to run at full load continuously. This improves diesel utilization efficiency and raises power generation from 1.7 kWh to 2.5 kWh per liter of diesel, cutting diesel consumption greatly.
• Adaptable to impact loads of pile drivingPavement pile driving equipment features high-power impact loads. Energy storage responds rapidly to instantaneous power fluctuations for peak shaving and valley filling, avoiding frequent start-stop and overload of diesel generators.
• Noise & emission reduction to meet site environmental requirementsReduced operation hours of diesel generators lower noise and exhaust emissions, complying with environmental regulations for highway construction sites.
• Stable and reliable power supplyRedundant configuration of diesel generators and energy storage. 2 diesel gensets and 2 energy storage units serve as mutual backups, ensuring continuous pile driving operation and minimizing downtime risks in off-grid field sites.

Applicable Scenarios:

This diesel-storage hybrid solution can be applied to highway subgrade piling, bridge foundation piling, slope support piling and other field infrastructure construction sites. It replaces conventional pure diesel generators to achieve cost reduction and efficiency improvement.
