Paralleling Generators – How Does it Work?

Do you own an average power generator and want to increase the output? Your solution lies in the paralleling. It is a seamless way of joining forces of different machines and resulting in a smooth and powerful electricity supply. It’s a synchronized way of getting matchless energy.

In this article, we will explore paralleling generators and how they work. In the modern world understanding the mechanics of generator functioning is paramount. It enables you to analyze and improve the output. Let’s deep dive into the world of paralleling:

What is Paralleling?

Paralleling or parallel circuits are connections made so that currently get multiple paths to flow. In this way, voltage is divided the same across all ends. The same goes for the case of generators. Two machines join their input to give a surplus output.

Art of Synchronization- How Does It Work?

Have you ever wondered about paralleling generators and how it works? Let’s explore the myth behind this. It works by synchronizing two inputs of the same output voltage waveform. Under certain conditions closed transition is used to get desirable load.

All we need is a parallel cable or kit to join the. As a result, we get a sum of output from both sources. While synchronizing, many factors are considered, like size, type, and brand of inputs. Two generators of the same brand and size are used for this process.

Conditions for Generator Paralleling 

Generators demand appropriate conditions for parallel connection. Because they provide enhanced input to run heavy loads. Also, we can connect more than two inputs for the required power output. Strictly follow these conditions for paralleling generators:

  • Use inputs of the same load and starting watt.
  • Use generators of the same size and type.
  • Avoid mixing the equipped or non-equipped inputs.
  • The voltage and frequency waveform of all the generators must be the same
  • Use a quality paralleling kit for safe and controlled functioning.
  • The inputs may have some or different speeds, but the final one must be the same

Benefits of Paralleling Generators

Paralleling multiple sources provides more output at affordable rates. Also, it helps in load management and maintenance. This process is mostly used in emergency settings or to drive heavy machines. The following are some benefits of paralleling generators and how they work:

●    Amplified Power

It is an efficient way of getting higher power because of reduced losses. It saves fuel and maintenance costs and can power heavy appliances. In emergency situations, if the load demands more power, additional input is connected in parallel to meet the requirements.

●    Redundancy

By doing so you can get improved reliability and redundancy. A parallel system provides constant power to critical loads. Improved redundancy helps to eliminate failure. In case of a single generator failure, you can connect to another one.

●    Cost Effective

Machines with higher power are highly expensive. As a result of the power outage, the whole thing experiences damage. But in case of paralleling, if one input dies, you can change it with another one. Also, two average-size generators are more despicable than a single larger one.

●    Expandability and Flexibility

In parallel settings, it’s easy to vary load according to needs. Also, we can connect and disconnect both inputs according to the demand for power. The user didn’t have to pile up costly units and spend much on a larger system.

●    Ease of Control

This setting provides ease of control and maintenance. In case of individual failure, you can replace it or modify the settings. Also, a single control is enough to operate the whole setting.

Factors to Consider Before Paralleling Generators

If you are up for connecting generators in parallel. Consider these factors for proper working and attaining maximum output:

●    Compatibility

Before paralleling assess the characteristics of both inputs. Also, read the operating instructions and capabilities to ensure frequency and voltage match.

●    Phase Angle Matching

For proper synchronization, the phase sequence of one generator must match the other. This helps to prevent any instability.

●    Synchronization Capacity

Synchronizing capacity is another important factor to consider. Check whether they can be connected to prevent any phase mismatch.

●    Frequency Matching

Frequency and voltage should be equal for proper working. Operate both inputs at the same frequency to generate accurate electric waveform aligns.

●      Voltage Compatibility and Control

Measure the voltage magnitudes of both generators. Use a control system for each part. A small imbalance in magnitude results in potential inability.

●    Training and Expertise

Make sure to buy a good brand generator for paralleling. Also, ensure the operators and maintenance staff receive proper training for the particular task. Always consider professionals for future ease and effective management.

●    Fuel Consumption and Cost Analysis

Before setting up calculate the average fuel consumption and analyze the total cost. Search the generator industry and invest in efficient and affordable solutions.
