专利汇可以提供Control system for starting up and synchronizing a plurality of generators and method of operation专利检索，专利查询，专利分析的服务。并且An electrical control system for starting up and synchronizing a plurality of alternating current generators, such as emergency power generators, and a method of operation thereof. The plurality of generators are simultaneously connected to a common busline, and motive power is simultaneously applied to each of the generators. As the generators begin to supply power, synchronizing circuits monitor the power developed by each generator and cause the generators to maintain substantially identical speeds as the generators are brought up to a normal operating speed. Accordingly, when the speed of the generators reaches the normal operating speed, the generators are in synchronization. The common busline may then be coupled to the main voltage supply line to thereby energize the main supply line.，下面是Control system for starting up and synchronizing a plurality of generators and method of operation专利的具体信息内容。
