Why do generator manufacturers recommend that you use at least two diesel generators in parallel?

June 13, 2022
In today's social development environment, diesel generator sets are playing an increasingly important role, and all aspects of society are increasingly dependent on the support and development of electricity. Under normal circumstances, users purchase diesel generator sets with their own companies. However, when a larger capacity is required, the cost of purchasing a larger power unit will be very high. Compared with a single large diesel generator set, the generator manufacturer recommends you to use it. Two diesel generator sets are used in association for the following reasons:
1. Reliability
The repetition of the parallel tasks of multiple diesel generators naturally provides a more noteworthy reliability than the base load provided by a single diesel generator set. If a unit is in short supply, the basic burden is to be redistributed among the different units within the framework as needed. In many cases, base loads that require the most staggering levels of ruggedized power typically represent only a fraction of the typical power produced by the frame. The gensets run in parallel, which means the most basic components will have significant repeatability to maintain power whether or not one of the units goes out.
2. Scalability
When measuring generators to reconcile your need prerequisites, it is often difficult to precisely scale the increments in the stack and make enough arrangements for additional necessities. If the heap predictions are strong, your potential interest in diesel generators may be higher than usual. Then again, without stack projection, you won't have reliable backup power. Or maybe need to move to an expensive generator overhaul, or get another unit in spite of that in general.
By running gensets in parallel, there is a lower requirement to consider variety without compromising your budget or needing expensive units for occasional use. Generators can provide additional power when needed, no matter how long you have enough physical space. Thus, the duplicate diesel generator can be disconnected from the unit and used independently in different locations.
3. Flexibility
Using various unit diesel generators in parallel provides more outstanding adaptability than using individual high-limit estimated diesel generators. Multiple diesel generators running in parallel should not be clustered together and can be in this situation. In the cycle design, the requirement for the huge impression of a separate, larger generator is reduced. Setting up rooftop facilities or setting up small generators in restricted areas are just a few of the ways you can get creative and find ways to make them fit. Since these units do not require an overall huge space that has to be adjacent, these can be introduced regularly in small offices or anywhere where space is a limiting variable.
4. Ease of Support and Maintainability
There is little chance that the diesel generator in the frame will detach or require maintenance. A single unit can go bad and be adjusted without affecting the work of different units. The repetitive nature of the parallel architecture provides different layers of insurance and guarantees continuous power to the basic circuits.
5. Cost Feasibility and Quality Performance
A single diesel generator running in parallel generally has lesser restrictions. As part of these generators, the engines are typically industrial, street or high-capacity engines with cutting-edge production innovations that give them a high level of unwavering quality and minimal burn-in work per unit of power.
In addition, it is worth noting that the capacity principle of multi-generator parallel operation is: when the generator capacity does not exceed 800kW, a single generator can be selected; when the capacity is above 800kW, two or more generators should be selected, but not more than 3 generators. ; When multiple units are selected, the units should choose a complete set of equipment with the same physical parameters such as model and capacity, and similar pressure regulation and speed regulation characteristics, so as to facilitate parallel operation of the units;
