How Do You Choose the Right-Sized Generators for Agricultural Irrigation Systems?

If you are wondering about the right selection of generators for agricultural irrigation systems, we have added the key tips.

提示 #1: Calculate Total Power Requirements Correctly

One of the biggest mistakes is always with the power calculations. Suppose you want to calculate overall power consumption. It is not just the pump you should include. 反而, you must focus on the other equipment, such as the fertigation system, borewell pumps, and all other equipment listed. 而且, check their quantities as you need a power system with high compatibility for your needs.

Let’s calculate the power requirements of the tools used in the agricultural irrigation systems.

Largest motor = 37 千瓦

Starting multiplier = 3×

Starting load =

37 × 3 = 111 千瓦

Other equipment continues running:

111 + 22 = 133 千瓦

Add a recommended safety margin of 20%.

133 × 1.20 = 160 千瓦

Whenever buying the generators for agricultural irrigation systems, you must focus on the total power requirements and starting loads. 一个 200 kVA generator would comfortably provide power in this case.

提示 #2: Match the Generator to the Irrigation Pump Type

Pump consumption and electrical demands vary from one irrigation pump system to another. Every pump has a different and unique system.

In addition to the horsepower, features and other factors matter in this case.

Here are a few tips to consider when choosing matching generators for your irrigation pump systems.

• What is the motor’s starting method? There can be DOL, 星三角, 软启动器, or VFD starting options.
• Verify the pump manufacturer’s recommended voltage tolerance.
• Operating generators at 80–85% load continuously is very critical. You should avoid selecting generators that operate above 85%.

提示 #3: Choose Appropriate Generator Ratings

If you are looking for the right generators, there are three different ratings. They operate differently and provide power in different situations.

Let’s uncover those three generators here.

• 备用发电机. They are useful only during the energy cases. Example use cases are farms with reliable utility power.
• 主要发电机. They offer a seamless energy generation and handling of varying loads for several hours a day. It powers farms that irrigate daily for several hours.
• Continuous Power Generators. They offer continuous and quality power supply. Such generators are ideal for remote agricultural projects without utility access.

提示 #4: Select the Right Fuel Type

In the case of generators for agricultural irrigation systems, there are several fuel types. Even each fuel type has different applications and requirements.

Here is the list of fuel types.

• Diesel is the best and high-output fuel with a moderate initial cost.
• Natural gas offers lower power but features clean and sustainable energy production with no noise pollution.
• Biogas has a high investment but produces low-cost energy because of organic waste.
• PTO generators are most affordable but have a lower efficiency.

You should consider the fuel types and choose generators based on the fuel requirements and consumption systems.

提示 #5: Evaluate Fuel Tank Capacity

Fuel is the main factor behind the continuous running of the generator systems. If you run out of fuel supply, the generators will stop and ultimately cause issues. Based on the runtime, you should calculate the fuel consumption and choose the right generator.

例子

Generator Size = 200 千伏安

Average Load = 70%

Fuel Consumption ≈ 28 升/小时

Operating Time = 10 小时/天

Daily Fuel Need

28 × 10 = 280 liters/day

Weekly Requirement

280 × 7 = 1,960 liters/week

提示 #6: 考虑环境条件

Agricultural farmlands are always exposed to the outdoors and face more challenges. 例如, sudden rainy weather or dust and insects can affect them.

Due to moisture and water exposure, components get rusted. To combat all such cases, you should have the following additional features.

• 防风雨外壳
• Dust-resistant air filtration
• 重型散热器
• Corrosion-resistant canopy
• Elevated base frame for flood protection
• Rodent-resistant wiring
• Rain protection

提示 #7: Voltage Regulations and Power Quality

Modern agricultural irrigation systems have a few sensitive devices. 例如:

• PLC controllers
• Automatic valves
• 变频驱动器 (变频器)
• Moisture sensors
• Remote monitoring systems
• Fertigation controllers

These devices get damaged due to fluctuations in the voltage and power. 所以, you should have those generators for agricultural irrigation systems that offer a stable power supply and decrease the chances of impacts on these devices.

Common features are:

• 自动电压调节器 (调压器)
• 电子调速器
• Stable frequency control
• Low harmonic distortion
• 快速负载响应

提示 #8: 考虑未来的扩张

Many farmlands have expanded over the years. Buying a generator with no future expansion plans can cause undersizing when you expand the system.

所以, you should consider the future expansions as follows.

Current Load = 140 千瓦

Planned Expansion = 30 千瓦

Future Automation = 20 千瓦

Future Total

140 + 30 + 20 = 190 千瓦

Adding a 20% reserve:

190 × 1.20 = 228 千瓦
