Diesel Generator Power Selection for Property Communities

What is the typical KW rating of diesel generators used in property communities? The power specification of a diesel generator to purchase is determined by the specific load requirements and is not fixed. When selecting the generator power, in addition to considering the sum of the electrical power consumption, it is also necessary to account for the starting current of each electrical device.

The electrical equipment in property communities that cannot tolerate power outages generally includes passenger elevators, fire pumps, water supply pumps, emergency lighting, and some emergency devices. The power consumption of these devices should be calculated, followed by consideration of the instantaneous starting current of each electrical device. Electrical devices typically have two starting methods: direct start and reduced-voltage start or variable-frequency start. The former has a starting current approximately 6 times the operating current, with instantaneous power also reaching 6 times the rated power; the latter has a starting current around 3 times, with instantaneous power also 3 times the rated power. When purchasing a diesel generator set, technical personnel should first collect information on the community's emergency electrical equipment and then consult with diesel generator manufacturers for reliable advice.

Domestic diesel generator sets have two power ratings: continuous (rated) power and standby power. The continuous power is the power at which the generator set can operate continuously for 12 hours, while the standby power can only be operated for 1 hour within a 12-hour continuous operation period.

Therefore, the correct selection of generator sets: For rated output power, the maximum output power of the diesel engine should be greater than 20% of the generator's output power. For standby output power selection, the maximum output power of the diesel engine should be greater than 10% of the generator's output power. Guangxi Dingbo Generator believes this approach is both economical and practical.

It is also important to note that if the property community does not have a dedicated diesel generator room and the unit needs to be placed outdoors, a silent diesel generator set must be chosen. These units have low noise levels, do not disturb residents' lives, and are windproof, rainproof, dustproof, and easy to maintain.

What KW diesel generator set is generally used in property communities, and should Yuchai, Cummins, or Shangchai be chosen? There are many generator set brands, each with different performance characteristics, and typically different power ranges correspond to different recommended brands. Brands like Yuchai, Cummins, and Shangchai generator sets are all excellent choices, offering high cost-effectiveness, good quality, stable performance, and low fuel consumption. Most property communities opt for these three brands. Yuchai and Shangchai are domestic brands, while Cummins is a joint-venture brand. Each brand has its own advantages in different power ranges. The most suitable brand depends on the specific power requirements and the corresponding diesel engine model prices.

Guangxi Dingbo Generator Set Manufacturing Co.,Ltd. was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to [email protected] we will pay highly attention on your question.
