Intertie protection of consumer-owned sources of generation, 3 MVA or less: summary report of an IEEE working group report

Abstract

A special publication, "Intertie Protection of Consumer-Owned Sources of Generation 3 WVA or Less," has been recently prepared by the Power System Relaying Committee to assist those people involved in the installation, application, and operation of interconnected Dispersed Storage and Generation (DSG) systems. The purpose of this paper is to highlight protection considerations, other than surge protection, associated with the connection of small, dispersed sources of generation to utility distribution lines. Primary emphasis is given to detection of system disturbances or conditions that would require generator separation. Background information on the various types of utility distribution systems and small generators is provided to facilitate communication between utility engineers and owners of small generation sources.Protection of the DSG facilities, including the generators, power delivery systems, and auxiliary equipment, was not within the scope of the special publication and is not discussed in this summary.
