In a larger data center room, several or even more than 10 diesel generators parallel operation of the situation more and more. In the power outage, the diesel generators in addition to the fastest time can start from the start, but also should maximize the response to the emergency load of start-up and power supply capacity requirements, if the capacity of the small choice, the motor starting voltage drop too large, the capacity of the election is too large, the operating economic benefits. This paper discusses how to choose the capacity of single diesel generator, and selects several diesel generators to meet the system's emergency requirements, and does not cause the waste of capacity.
The diesel generator is one of the internal combustion generators, it takes diesel as an energy source, the diesel engine is the original motive, it has the following characteristics:
① fuel price is cheap, easy to save;
② simple structure, less auxiliary equipment;
③ start fast, with load and downtime of the short time;
④ operation maintenance is simple and convenient.
It is precisely because of the above characteristics, the use of diesel generators in the data center is also more and more widespread. With the gradual enlargement of the data center room scale, the data center room of the high level distribution system is also in the proportional increase, because the level a computer room requires the power system not to interrupt, so in the larger data center room, several even more than 10 diesel generators parallel operation situation more and more. In the power outage, in addition to the fastest time to start from the start, but also should maximize the response to meet the emergency load of start-up and power supply capacity requirements, if the capacity of small selection, the motor starting when the voltage dropped too large. The capacity is too large, the economic performance is poor. So how do you choose the capacity of a single diesel generator? Using several diesel generators to meet the system's emergency requirements, without causing a waste of capacity?
