Benefits and Precautions of 700kW Generator Set Paralleling

Paralleling 700kW generator sets is employed when the capacity of a single unit fails to meet the requirement for large-capacity power supply. The advantage lies in enhancing power supply capacity while reducing costs. The conditions for parallel operation demand that the voltage, frequency, and phase of the two units are identical at the instantaneous moment, commonly referred to as the "three synchronizations". Parallel operation is achieved through a dedicated parallel operation cabinet.

What are the benefits of paralleling multiple generators?

1.When multiple generator sets are paralleled to form a power grid, the power supply system becomes relatively more reliable, continuous, and stable, capable of withstanding the impact of larger load changes.

2.Greater economy is achieved. For instance, if a user normally requires 700kW, opting for a single 700kW generator would cost significantly more than choosing two 350kW generator sets. Additionally, the oil and fuel consumption required during parallel operation are much lower.

3.The parallel operation of multiple diesel generator sets allows for the centralized dispatching of active and reactive loads, facilitating more convenient maintenance of the units.

4.The initial investment is lower and the scalability is stronger. This is because only the power generation equipment and parallel devices with the currently required power need to be installed. If there is a need to expand the grid capacity in the future, additional generator sets can be added.

Precautions for diesel generator set paralleling

Before conducting the paralleling operation of diesel generator sets, the overview of the paralleled units must meet the following four conditions:

(1) The waveform and effective value of the unit voltage must be consistent;

(2) The phases of the voltages of the two generators must be the same;

(3) The frequencies of the two generator sets must be the same;

(4) The phase sequences of the two generator sets must be consistent.

The above four points must be satisfied to facilitate the parallel operation of diesel generators. During the parallel operation of diesel generator sets, manual operation is not required because the success of manual parallel operation depends on human experience, which can easily lead to safety accidents.
