Long-term spontaneous power generation
The mining area is far from a stable power grid, and the diesel unit runs for a long time every day. Fuel and maintenance costs will accumulate over a long period of time.

Diesel generator + energy storage solution
Mine diesel generatorEnergy storage solution
The diesel generator bears the basic continuous load, and the energy storage cabinet bears short-term peaks, starting shocks and low load periods at night. It is suitable for mining sites with long-term self-generation, large load fluctuations, and high oil replenishment costs. The engineer first calculates the configuration value based on the load curve.

Suitable mining site
With large load fluctuations and high refueling costs, energy storage has accounting value.
The energy storage cabinet does not look at the capacity alone, but at the load curve of the mining area. The following sites are more suitable for incorporating energy storage into diesel power generation systems for evaluation.
Load fluctuation is obvious
The loads of crushing, pumping stations, conveying, camps and workshops vary greatly in different periods, and the peak and base loads are significantly different.
Diesel transportation costs are high
The refueling distance is long and the impact of roads or rainy seasons is obvious. Reducing ineffective operating hours will directly affect long-term costs.
Obviously low load at night
Nighttime lighting, communications, security, camps and a small number of pumping stations have small loads, and it is uneconomical for large units to continue to operate at low loads.
The impact of short-term start-up is obvious
Motor starting, voltage drops or short-term peaks force the site to configure larger units or run multiple units at the same time.
Solution advantages
Energy storage cabinets mainly solve the problems of peak value, low load, parallel time and operating hours.
Whether it is worth configuring energy storage depends on the load curve, peak duration, fuel cost and unit operating records. The engineer will first calculate and then provide the capacity and control plan.
Reduce peak configuration pressure
Short-term peaks and start-up shocks may not all be solved by amplifying generator capacity. Energy storage PCS can participate in short-term discharge support.
Reduce parallel running time
The regular load is borne by the main unit, the energy storage handles short-term fluctuations, and the backup unit can reduce unnecessary simultaneous operation hours.
Reduce low load fuel consumption waste
During low-load periods such as night, camps, communications and security, energy storage can take on part of the load, allowing the unit to maintain a more reasonable load rate.
Reduce maintenance pressure
The operating hours and start-stop rhythm are more controllable, and the consumption of oil, filters, batteries, belts and common spare parts is easier to manage on a cycle basis.
System access
The energy storage cabinet is connected to the diesel power generation system, instead of placing a separate battery
The core is load grouping, ATS/parallel control, PCS power and remote monitoring. Which loads the energy storage supports and when it is charged and discharged must be designed together with the low-voltage power distribution.
Diesel generator set
Bears the basic continuous load and key backup capacity, and is the underlying guarantee for the main power supply and safe load in the mining area.
Energy storage cabinet / PCS
To bear short-term peak value, starting shock, low load at night and load fluctuation, it is necessary to combine the load curve selection.
ATS / parallel control
Coordinate switching and parallel logic between units, energy storage and key loads to reduce on-site temporary operations.
Low voltage distribution and load grouping
Distinguish crushing, drainage, camps, communications, workshops and safety loads to determine the energy storage support range.
Remote monitoring
Put the unit load rate, operating hours, BMS/EMS, SOC, alarm and power distribution status in the same set of data for review.
