Resposta I.Core

The Huaquan plateau-specific generator set is a specialized power generation equipment designed for the harsh environment of high altitudes, hipóxia, baixas temperaturas, e forte radiação ultravioleta, com altitude superior 3000 metros. The core difference between it and ordinary units lies in the systematic technological upgrades aimed at addressing two major pain points of the plateau: “power reduction due to thin air” e “difficulty in starting due to low temperatures”.

Limitations of ordinary units:

• The standard operating altitude is not to exceed 1000 metros
• For every 1000 meters increase in altitude, the power of a non-turbocharged engine decreases by approximately 6-10%
• The power loss of a naturally aspirated engine is about 3% for every 300m increase in altitude
• Difficulty in starting under low temperature conditions, and deteriorated heat dissipation conditions of the cooling system

Solution for Huaquan Plateau-specific Unit:

• Comprehensive optimization is carried out from engine intake, fuel injection, low-temperature start-up to power matching
• It has undergone practical project verification at an altitude of 5600 metros and possesses extensive operational experience
• Successfully applied in mines, oil drilling, daily electricity consumption, and other scenarios in high-altitude areas such as Xizang, Qinghai, and Sichuan

II.Three major challenges posed by high-altitude environments to generator sets

1. Power decrease (due to thin air)

This is the greatest challenge faced by generator sets in high-altitude areas.

Data description:

• The higher the altitude, the lower the air pressure, the thinner the air, and the less the oxygen content
• This results in insufficient fuel combustion and a decrease in engine output power
• For non-supercharged engines, power decreases by approximately 6-10% for every 1000m increase in altitude, while for supercharged engines, the decrease is around 2-5%
• For naturally aspirated engines, the power output typically decreases by approximately 3% for every 300m increase in altitude

2. Difficulty in starting at low temperatures

Huaquan Power lembra você that under the dual influence of high altitude and low temperature, the startup success rate of ordinary generator sets is significantly reduced, and an auxiliary preheating device must be equipped.

3. Deterioration of heat dissipation conditions

III. Six core features of Huaquan’s high-altitude dedicated generator sets

Recurso 1: Turbocharging and intercooling technology – plateau power compensation

Configuration description: The Huaquan high-altitude dedicated unit comes standard with exhaust gas turbocharging and intercooling technology.

Technical Principles:

• By increasing the intake air density through exhaust gas turbocharging, we can compensate for the insufficient intake air caused by the thin air at high altitudes
• The intercooler reduces the intake temperature, thereby further increasing the intake density
• It can effectively restore engine power and reduce fuel consumption rate

Actual effect: At an altitude of 5000 metros, the power loss of the turbocharged model is only about 10-25%, while the loss of the non-turbocharged model can reach more than 30-50%.

Huaquan case: A 150kW silent box-type generator set, featuring an inline 6-cylinder four-stroke engine, equipped with an electronic controle de velocidade fuel injection pump and turbocharged intercooling technology, was sent to Xizang with an altitude of 5000 metros. This significantly alleviated the issue of incomplete combustion caused by the high altitude.

Recurso 2: Special fuel injection system for high altitudes

Configuration description: Equipped with an electronically governed fuel injection pump for precise control of fuel injection quantity.

Technical Principles:

• Automatically adjust the fuel supply based on the intake air volume to avoid “rich” combustion (too much fuel, too little air)
• Prevent black smoke and excessive fuel consumption
• It is recommended to appropriately advance the fuel supply advance angle of non-turbocharged diesel engines to improve operational economy

Actual effect: Compared to ordinary mechanical pump units, the plateau-specific injection system can save 5%-10% of fuel while reducing carbon deposits and emissions.

Recurso 3: Low-temperature startup system (guaranteed at -40℃)

Configuration description: The Huaquan plateau-specific unit is equipped with a multi-stage heating system to ensure reliable startup in severe cold environments.

Heating configuration of Huaquan’s high-altitude dedicated generator set:

Huaquan case:

• The 150kW plateau unit is equipped with a dedicated module for high altitude and low temperature conditions, as well as a fuel heater. With one-click heating, the machine can be pre-warmed in advance, ensuring easy startup even in harsh low temperature environments
• The 2000kW containerized generator set utilizes flame-retardant insulation materials, covering various positions such as walls, portas, and ceilings, and is equipped with an indoor heating system

Recurso 4: Dedicated control system for high altitude

Configuration description: Huaquan high-altitude units utilize a dedicated control module specifically designed for high-altitude, low-temperature environments.

Características:

• Monitor environmental temperature, atmospheric pressure, and unit operating parameters in real-time
• Automatic adjustment control strategy, adapting to different altitudes
• It features quadruple protection against low oil pressure, high water temperature, excesso de velocidade, and overload
• Equipped with emergency lighting system and safety assurance system

Practical application: Huaquan plateau units have successfully operated in a solar-thermal complementary power generation project at an altitude of 5,600 metros. The project utilizes a 1200kW/10500V high-voltage generator set, with two units operating in parallel.

Recurso 5: Extra-large capacity base fuel tank

Configuration description: In response to the inconvenience of fuel transportation in plateau areas, Huaquan’s plateau units are equipped with ultra-large capacity base fuel tanks.

Design considerations:

• In high-altitude areas, the refueling cycle is long, so a large fuel tank ensures long-term operation
• Reduce the frequency of fuel transportation to lower operating costs

Huaquan case: A 150kW unit sent to the 5000-meter high altitude in Xizang was equipped with an ultra-large capacity base oil tank to ensure long-term operation of the unit.

Recurso 6: Soundproof box and humanized design

Configuration description: The unit designed for high altitudes can be equipped with a soundproof enclosure and features humanized design tailored for cold environments.

Characteristics of soundproof box:

• The outer side features a humanized design with wind hooks
• In harsh environments with high altitudes and low temperatures, it is essential to ensure personnel safety when performing maintenance
• The soundproof box also has the function of heat preservation and cold prevention

Electric shutters: Huaquan Plateau container units are equipped with electric shutters that can automatically adjust their angle according to the wind volume, providing a suitable temperature for the normal operation of the units and effectively extending their service life.

VII. Suggestions for selection of plateau units

1. Power correction calculation

Huaquan Power recommends adjusting the power as follows:

Calculation formula:

Selected power = Actual load power ÷ Altitude correction factor

Exemplo: In an area with an altitude of 3500 metros, where a 100kW load needs to be driven, it is recommended to select a power of 100 ÷ 0.85 ≈ 118kW, and to choose a 120-150kW high-altitude dedicated unit.

2. Low-temperature startup configuration
