CONNECTING A PRIME MOVER DRIVEN ALTERNATOR TO A CIRCUIT WITH AN EXISTING ALTERNATING CURRENT

摘要

Apparatus and method are provided, for connecting prime mover driven alternator (102) to circuit (104) that has an existing alternating current. Alternator (102) is connected to circuit (104) when minimum current flows to or from alternator (102). The actual current is measured by controller (142) following connection and the value of this current is used to determine the optimal connection conditions when alternator (102) is next connected. Alternator (102) is disconnected by controller (142) by running down prime mover (103), monitoring the current and stalling prime mover (103) when the current flow is at a minimum.
