Three Tips to Quickly Choose Emergency Diesel Generator Sets

There are many classification methods for diesel generator sets, which can be divided into commonly used sets, backup sets, and emergency sets according to their purposes. Emergency diesel generator sets are mainly used in important places such as fire protection systems in high-rise buildings, evacuation lighting, elevators, control systems for automated production lines, important communication systems, and medical equipment undergoing important surgeries with patients. Emergency diesel generator sets are usually in a shutdown and standby state, and are only activated in case of emergency or transient power outages. At this time, the emergency diesel generator set can quickly restore and extend the power supply time. Emergency diesel generator sets usually only need to run continuously for a few hours. So, what should users pay attention to when choosing an emergency diesel generator set? This article teaches you the three tips of Dingbo Electric Power to quickly choose emergency diesel generator sets.

1. Determine the required power level

When choosing an emergency diesel generator set, the first thing to consider is the power size you need. So, how to choose the power size of the set that is practical for yourself? Here, first of all, it is necessary to understand how the power of the emergency generator set is determined. The calibrated power of the emergency generator set is the 12 hour calibrated capacity after environmental correction (it should be noted that it may vary due to differences in altitude, atmospheric pressure, and air humidity). Its power should be able to meet the total calculated load of emergency electricity, and it should be verified according to the generator capacity that can meet the requirements for starting a single maximum capacity generator in the first level load. In this way, it is easy to determine the required capacity of the unit.

2. Clearly specify the number of units that need to be purchased

Determine how many emergency generator sets are needed to provide sufficient power supply during emergencies based on one's own needs. At this time, if there are multiple backup generator sets, usually only one emergency generator set is set up. From the perspective of reliability, two units can also be selected to run in parallel for power supply. The number of emergency generator sets should usually not exceed 3.

When multiple diesel generators are selected, the units should try to choose complete sets of equipment with the same specifications, capacity, and similar pressure and speed regulation characteristics. The properties of the fuel used should be consistent for operation, repair, maintenance, and shared spare parts. When there are two generator sets for emergency supply, the self starting device should enable the two units to be mutually backup, that is, after a delay confirmation of the power failure of the mains power supply, a self starting command should be issued. If the first unit has difficulty starting for three consecutive times, an alarm signal should be issued and the second unit should be automatically started.

3. Performance and brand of emergency diesel generator set selection

Cummins generator sets used for emergency purposes should generally choose high-speed, turbocharged, low fuel consumption, high reliability, and diesel generator sets of the same capacity. High speed turbocharged diesel generators have a large single unit capacity and occupy a small space. Diesel generators are equipped with electronic or hydraulic speed control devices, which have good speed control performance. It is recommended to choose synchronous generators with brushless excitation for reliable operation, low failure rate, and convenient maintenance and inspection; At the same time, when selecting emergency diesel generator sets, it is also necessary to choose the right brand. Currently, domestic brands Yuchai and Shangchai are good choices. If you want to purchase imported brand generator sets, Dingbo Electric recommends choosing international big brands such as Cummins and Volvo. These brand generator sets have superior performance, compact layout, accurate and rapid combustion organization, good transient response performance, strong loading capacity, large power reserve, strong power, energy-saving and environmental protection, and can provide safe, stable and reliable power guarantee. They are the better brand choices for purchasing emergency diesel generator sets.

Dingbo Power 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 sales@dieselgeneratortech.com we will pay highly attention on your question.
