Assessment of Distributed Generation on the Efficiency of Single Wire Earth Return Systems

Abstract:

Single-wire earth-return (SWER) systems are low capital and maintenance cost distribution systems, which have been chosen and widely built in many rural parts of the world. While low load density is main cause of over voltage phenomenon, voltage drop problems caused by continuously increasing electricity consumption is more common and requires urgent attention in order to enhance system capacity and reliability of aging SWER systems. This paper will investigate potential alternatives for given problem, include conventional solution such as capacitor bank compensation. Case studies on the Wambo Creek SWER system are used to assess the impacts of integration of renewable or distributed generation against other mitigations and the issues are discussed.
