| Summary: | An Automated Transfer System (ATS) is to provide automatic
power transfers to groups reloading loads from common sources, such as
utility services, to alternative sources, such as standby generation, in the
event of a normal source failure. The project aims to develop a new design
of an automatic power transfer system for the 11kV switchgear. Using the
basic building blocks of utility power, system topology, on-site generation,
and uninterrupted power supply, the basic role of the automatic transfer
system can now be determined.
In this role, the Automatic Transfer System (ATS) must achieve two
goals. First, the system must be stable where it should operate, even under
abnormal power systems, without human intervention. Equally
important, it must be able to distinguish when the system conditions do
not guarantee transfer to alternate sources. Second, it must be able to
control the switchgear as required and, in addition, be able to deliver
accurate signal to the required alternative power sources (for example, to
initiate start signal to the generator as soon as possible). |
