A diesel generator is an electro-mechanical machine that produces electricity. It consists of a diesel engine coupled to the alternator. It’s primary purpose is to provide power when the electrical grid is not available due to many factors (remote areas, grid stability, fault). Growing nations have grids that are not stable and therefore have a sizable use of diesel generators. In developed nations grid source is generally stable thus the applications are constrained to areas such as critical power (hospitals, data centres, airports), commercial where loss in power will get significant costs and distant areas (mines, communities) where grid supply is no. Other applications include military services, marine and telecom. Diesel Generator Brands
The type of diesel electrical generator required will be centered on several factors such as:
– Prime or Standby Electrical power
– Operating Conditions
One of the opposite ends of the generator spectrum in conditions of type is as follows. The first application is perfect for a mine site in a remote control area in extreme conditions (heat, dust) operating more than 8 hrs a day and downtime may cause significant financial loss. The other application in comparison is to provide standby electric power in a stable main grid located in a building where it is to provide power to operate essential services. The first application would desire a quality product that is proven in such applications and the second a typical off the shelf product where price will be the key criteria.
The ideal diesel engine generator would have the following features:
– High performance
– Local knowledge
– Competitive pricing
– User friendly
There may be a sizable range of generator manufacturers in the market place. The top-tier are the large diesel engine engine companies based in the United States with power generation divisions. The mid-tier a mostly European and Chinese companies who put together generators meeting international criteria. Low-tier are generally Far east companies using local brand name components to Chinese ideals.
Top-tier companies will use components made within the company that could be lacking in certain areas. A good example their engine may be ideal but alternator is not reliable or the other way round. Another example is that they may have a controller that is complex and requires costly call out to company technicians. Design deviation to suit applications is limited as the acceptance process within these firms is onerous and triggers inefficiencies in production. Prices is at the expensive leveraging off their personalisation and global presence.
Mid-tier companies provides all the features of an excellent diesel powered generator. They are not linked with any particular brand of component given them scope to put collectively the best components to generate a quality diesel generator. Since of their large plant life they have scalability and can acquire components at competitive pricing. Designs can be flexible to accommodate different applications. Pricing on the whole can be up to thirty percent below top-tier generators.
