A GENERATOR SYSTEM AND METHOD OF OPERATING SUCH A GENERATOR SYSTEM

摘要

A generator system comprising a local a.c. generator (14) that is operable to be connected to a utility power line (L1, L2 and L3) and a load (12), a current sensor (S1, S2 and S3) for sensing instantaneous current demanded by the load (12) and a controller (15) for varying the output of the local a.c. generator (14) to cause it to supply a pre-determined fraction of the instantaneous current demanded, preferably substantially all of the current demanded.
