Selection criteria of diesel generator set
2021-10-08
1、 Main factors to be considered in the selection of diesel generator set
The factors to be considered in the selection of diesel generator set mainly include mechanical and electrical performance, purpose of the unit, load capacity and variation range, automation, static speaker, mobile power station and other functions.
1. Purpose of the unit. Since the diesel generator set can be used in three situations: common, standby and emergency, the requirements for diesel generator set for different purposes are different.
2. Load capacity. The load capacity and load variation range shall be selected according to different purposes, and the single unit capacity and standby diesel generator capacity of diesel generator set shall be determined.
3. Operating environmental conditions of the unit (mainly referring to altitude and climatic conditions).
4. The unit is designed with advanced control system and special program controller, which can automatically start the unit and put it into operation for power supply in case of mains power loss, phase loss and undervoltage; In case of fault, the audible and visual alarm device will automatically alarm, memorize the fault point, and automatically unload and shut down to ensure the safety of the unit. The control screen adopts full Chinese fluorescent display screen and soft touch switch, which has the characteristics of good hand feeling, clear display and reliable action. At the same time, the control panel for automatic grid connection of more than two units can also be designed for users. The Japanese Mitsubishi programmable controller PLC is used as the main control unit, and the Japanese variable pulse width and variable pulse interval software is used to design the speed regulation, so that the regulation process is very fast, accurate and stable, and the performance is stable and reliable. The automation system can be selected according to their specific requirements
5. Some enterprises have high requirements for silence, such as schools and communities, which requires a quiet speaker.
6. The excitation mode of diesel generator set also needs special attention.
2、 How to choose diesel generator set
Some diesel generator sets need to be continuously operated for a certain period of time or often for a long time to serve as the common power supply for power load. This kind of generator set is called common generator set. For towns, islands, forest farms, mines, oil fields and other areas or industrial and mining enterprises far away from the large power grid, diesel generators need to be installed in order to supply power for local residents' production and living. Such generator sets should be installed continuously at ordinary times.
However, after the power failure due to the destruction of the municipal power grid due to earthquake, typhoon, war and other natural disasters or human factors, the set standby generator set shall be started quickly and carried out continuously for a long time, so as to ensure the continuous power supply to the power loads of these important projects. This standby generator set also belongs to the type of common generator set.
The performance and quality of the selected diesel generator set must meet the requirements of relevant standards. Therefore, when you buy enough, you must consider carefully, ask the supplier clearly, and choose the most suitable diesel generator set.
