subject: Secure Your Power Supply by Having a Backup Generator to Compliment UPS Power Protection [print this page] It is not uncommon however for power supplies to fail for prolonged period of times and often in these situations the UPS systems battery will beexhausted. It is in this situation where a standby generator and fuel supply is necessary in order to maintain a power supply. It is not enough to have any backup generator as they do not come online automatically unless they are paired with the correct UPS system. There are many varieties of backup generators and UPS systems meaning that matching the two is vital.
The UPS and generator must be matched correctly because if they are not they can create problems for each other. The most common problems are that a generators frequency range can sometimes be too wide for a UPS system to handle or that the generators slew rate is to fast for the UPS system to safely follow. This issue can be overcome by installing an electronic governor to the backup generator which will manage its output by limiting the frequency. A further issue is the UPS can also interfere with how the generators control power as they often include rectifier charge control circuits which enforce notches on the power feed.
As well as the backup generator being matched to the UPS it must also be sized correctly with relation to the load the UPS is capable of taking on. The generator must be able to fulfil all of the duties that the UPS system fulfils as well as extra loads. For example there is little point in ensuring that all of the computer systems in a building work if the air conditioning which maintains an optimum temperature for them to work at is not functioning.
