A typical emergency power system once consisted of a single generator and distribution equipment, but more facilities are realizing the benefit of using multiple smaller generators in parallel to address emergency load requirements, according to a blog on the Electrical Construction & Maintenence by Krista Biason, HGA Architects & Engineers.
Paralleling generators are an excellent design alternative when funds are limited, acccording to the blog.
"Instead of purchasing a standalone 'right fit' gen-set, which may not have the capacity for expansion, or oversizing the generator to accommodate both current and future loads, a multiple generator approach is a good choice," Biason wrote.
A paralleled system with paralleling gear with bussing suitable for the desired target load can be more a cost-efficient and flexible design.
