This paper describes the construction and test of a software model of a weak rural distribution network containing embedded water turbine driven synchronous generators (EGs). The characteristics of the network and its influence are related by development of the universal power circle diagram. The delivery of active and reactive power when the EG is operated purely in automatic power factor control (APFC) is compared with that when operated in automatic power factor control modified by voltage control (AVPFC). It is shown that this combined control enables increased EG dispatch within statutory network conditions.
