1. A power system comprising:

  • two generator sets connected in parallel to a common bus, each of the two generator sets having a switch between an output of each of the generator sets and the bus; and

    two modules, wherein each of the two modules is associated with one of the two generator sets and each of the two modules is configured to receive a signal from that module'"'"'s associated generator set when that module'"'"'s associated generator set is ready to energize the bus and to output a signal which allows that module'"'"'s associated generator set to connect to the bus, wherein the two modules are connected to each other;

    wherein the two modules are similarly configured such that when each of the two modules receives the signal that the module'"'"'s associated generator set is ready to energize the bus at substantially the same time, each of the two modules performs a similar method which provides that only one of the two modules is permitted to send the signal which allows that module'"'"'s associated generator set to connect to the bus.
