Engineers review capacity against load, operating hours, altitude, ambient temperature and duty profile to reduce low-load operation, oversizing and unclear refueling costs.
Mine power supply system configuration center
Mine procurement is for a complete power system configuration, not just a generator
Engineers first review mine loads, operating hours, altitude, expansion plans and site conditions, then define diesel generator sets, ATS, paralleling, low-voltage distribution, fuel, remote inspection and spare-parts support.
Voltage architecture
Low- and high-voltage mine power systems
Load voltage defines the generator, switchgear, cable route and distribution interface. Both architectures cover auxiliary loads through mine MV buses.
From equipment configuration and factory inspection to commissioning, load testing, spare parts and remote diagnosis, reduce downtime risk at remote mine sites.
Reserve interfaces for paralleling, ATS, low-voltage distribution, fuel autonomy and remote monitoring so later expansion and new loads can be added cleanly.
Mine power supply system configuration
Ask an engineer which equipment modules your mine power system needs
You do not need a complete configuration list at the start. Share the mine load, power problem, operating hours, and site conditions with an engineer, so a HOHANK engineer can define the right generator set, ATS, distribution and fuel-supply setup.
Layer 1
Main power supply equipment
First confirm how the mine will generate power on site, then review open-frame or containerized generator configuration against load, operating hours, altitude and installation conditions.
Open frame diesel generator set
For machine rooms, shelters or independent equipment areas, first review the open-frame unit power range, engine and alternator configuration.
500kW、600kW、650kW、800kW、1000kW、1200kW、1500kW、1800kW、2000kW、2400kW
Containerized diesel generator set
For outdoor mines, rainy-season roads, and high-dust sites, first review the containerized generator set structure and power range.
500kW、1000kW、1200kW、1350kW、1400kW、1500kW、1600kW、2000kW
High-voltage systems
Mining high-voltage power systems
Direct 6.3–11kV generation lowers current, cable losses and voltage drop over long runs while matching mine MV buses and large process loads.
500–2600kW · 6.3kV / 10.5kVLayer 2
Fuel Use, Long-Run Cost and Service Support
After the generator format is clear, review fuel use, tank sizing, refueling routes, remote monitoring, commissioning and spare-parts response together, so price comparison also reflects downtime and long-run operating cost.
Fuel Use, Tanks & Long-Run Cost
Estimate fuel use and long-term self-generation cost from load rate and running hours, then confirm tank capacity, refueling routes and whether diesel + storage is needed.
Load rate / Fuel estimate / Tank runtime / Refueling route
Remote monitoring and inspection
Connect controller, ATS, low-voltage distribution, fuel, and site-environment data so engineers can assess downtime risk remotely.
Operating data/alarm/inspection
Spare parts and after-sales support
From installation and commissioning, load testing, maintenance planning to spare parts and remote diagnosis, reducing waiting for downtime in remote mining areas.
Installation/Commissioning/Spare Parts/After-SalesLayer 3
Electrical access and control
Then confirm how power will transfer, how generator sets will parallel, and how critical loads will be distributed, so the units connect to a reliable electrical system.
Generator paralleling and expansion control
Synchronize multiple gensets, share loads and provide N+1 redundancy, with interfaces reserved for low-voltage distribution, monitoring and future loads.
Synchronized operation / Load sharing / N+1 / Phased expansion
ATS transfer for critical-load backup
Automatically transfer between utility and generator power, or between prime and standby sources, with priority set for dewatering, communications, safety lighting, camp and control systems.
Power transfer / Critical loads / Priority / Restoration logic
Low voltage distribution cabinet and load partition
Confirm incoming feeders, busbars and protection; separate crushing, screening, dewatering and camp loads into dedicated circuits; and reserve interfaces for ATS, paralleling, monitoring and expansion.
Incoming protection / Load segmentation / System interfaces / Expansion reserveOpen-frame generator configurations
Open-frame diesel generator sets: choose a power range, then confirm against mine loads
These open-frame configurations show common power and component combinations. HOHANK engineers confirm the final output, engine, alternator, starting method, ventilation, low-voltage interface and duty against the mine loads and site conditions.

View by mine site issues
Start with the mine-site problem, then choose the power configuration.
Around crusher starting, drainage-pump backup, off-grid self-generation, weak-grid standby, capacity expansion with paralleling, old-generator upgrades, and remote mine operating conditions, HOHANK engineers quickly define the generator, distribution, control and fuel scope so the discussion does not stop at the price of one generator set without distribution, fuel, and delivery conditions.
Site problem
Before starting the crushing station, screening equipment and conveyor line, review the on-site load and power distribution relationship.
Crusher startup problem
When the crusher, screens, and conveyors start, site voltage drops
- Site symptoms
- If startup bogs down the genset, trips protection, or stops the whole line, simply replacing it with a larger unit usually will not solve the root cause.
- Possible impact
- It will affect the continuous operation of crushing, screening, and conveying. In severe cases, it will also slow down the power consumption of drainage, camps and maintenance workshops.
- How engineers review it
- Engineers need to review starting current, simultaneous operating loads, generator-set capacity, paralleling control, low-voltage distribution, and critical-load priority together.

Site issue
For long-term self-generation, fuel truck access, tank capacity and load operation all become long-term cost factors.
Fuel and refueling cost issue
Long-term self-generation makes fuel use and refueling cost hard to control
- Site symptoms
- The mine is far from town, diesel transport depends on road conditions, fuel trucks are not always on time, and the site still needs continuous power.
- Possible impact
- Without a fuel estimate and refueling plan, day tanks, bulk tanks, delivery frequency and load operation become long-term cost pressure.
- How engineers review it
- Engineers check running hours, load rate, refueling cycle, tank capacity and transport route, then judge load grouping or diesel + storage options.

Share daily running hours, main load size, fuel delivery interval and available tank space, and a HOHANK engineer will calculate the long-term operating cost.
Running hoursLoad rateFuel distanceTank capacityRoad conditions
Site problem
In rainy seasons, tailings and low-lying operating areas, priority must be given to whether key water pumps can reliably take over.
Dewatering power protection problem
When dewatering pumps stop, water and safety risk rise quickly
- Site symptoms
- A power outage affects drainage. In rainy seasons or in weak power grid environments, slower manual switching may affect site safety.
- Possible impact
- It will affect stope drainage, road access, tailings safety and equipment protection. In severe cases, it may cause shutdown and waiting.
- How engineers review it
- Engineers need to look at the water pump power, starting method, backup time, ATS switching, on-site rain protection and fuel replenishment cycle.

Site problem
There is a large continuous production load, and the main power supply, power distribution partition and expansion reservation must be confirmed together.
Continuous production problems
Mineral processing plants and process lines need distribution design around the whole load chain, not a single equipment kW.
- Site symptoms
- Grinding, screening, conveying, pumping stations and auxiliary equipment operate at the same time. It is easy to miss the overall load relationship by looking at a few large equipment alone.
- Possible impact
- It can affect continuous operation of the entire processing line and may force repeated cabinet, cable, and generator-set configuration changes during later production expansion.
- How engineers review it
- Engineers need to review prime generator-set capacity, low-voltage distribution zones, critical-load priorities, operating hours, and expansion plans together.

Site problem
The load in the maintenance workshop changes greatly. First, the relationship between starting impact and simultaneous operation should be clearly explained.
Workshop startup problem
Air compressors, welders, and maintenance tools need capacity checked by starting impact, not rated kW alone
- Site symptoms
- Air compressors, welders, lifting equipment, and maintenance tools are not fully loaded all the time, but startup shock and transient loads can easily be underestimated.
- Possible impact
- It will cause difficulty in starting up workshop equipment, voltage fluctuations, and frequent alarms, affecting maintenance efficiency and production recovery speed.
- How engineers review it
- Engineers need to review maximum simultaneous load, starting method, workshop distribution, the prime/standby relationship, and on-site operating habits.

Site problem
Camp and communications loads may not be the largest, but they need stable voltage, noise control and dependable transfer.
Camp communication issues
Camp, office and communications power needs stable voltage and dependable transfer
- Site symptoms
- When lighting, offices, communications, living loads and equipment-room loads are mixed together, they should not be treated as ordinary backup power.
- Possible impact
- It will affect camp life, communications, night lighting and on-site management. Slow recovery after a power outage will also affect production organization.
- How engineers review it
- Engineers need to review critical load grouping, ATS transfer, sound-attenuated or containerized generator sets, installation location, and noise requirements.

Site problem
Weak power grid mining areas must first confirm which loads must maintain power and which loads can be delayed in switching.
Weak grid backup problem
When the grid fluctuates, critical loads should not drop offline at the same time.
- Site symptoms
- When the power grid voltage fluctuates, is interrupted, or is unstable in recovery, production loads and living loads are easily affected together if there is no priority.
- Possible impact
- It will cause critical equipment to shut down, control systems to restart, drainage and communications to be affected, and it will also increase on-site inspection time.
- How engineers review it
- Engineers need to review grid status, critical load list, ATS range, allowable switching times, and low voltage distribution interfaces.

Site problem
Multi-zone power supply is not simply about buying a few more generator sets. It requires clear planning for paralleling, zoning, and expansion stages.
Expansion and parallel problem
The production area, drainage area and camp area are powered together, and generator paralleling systems and partitions must be reserved in advance
- Site symptoms
- At the beginning, it only meets the current load, and later when the capacity is expanded and additional units are added, it is easy to encounter mismatches in parallel control, power distribution partitions, and redundancy relationships.
- Possible impact
- This will increase the cost of repeated modifications, shutdowns and on-site commissioning, and may also limit subsequent expansion of power supply.
- How engineers review it
- Engineers need to review partition loads, number of generator sets to be paralleled, synchronization control, redundancy requirements, low-voltage power distribution and subsequent expansion stages.
