When a small generator is connected to the distribution system, the voltage at the point of interconnection is determined largely by the system and not the generator. This paper examines the effect on the generator, on the load voltage and on the distribution system of a number of voltage control strategies. Synchronous generators with three kinds of exciter control are considered, as well as induction generators and constant extinction angle inverters, with and without capacitor compensation. Operation with a constant slightly lagging power factor is shown to have some advantages.
