IEEE 1409

Description / Abstract: This guide introduces and defines the emerging technology of custom power. This technology involves devices and circuit configurations of power electronic equipment used in utility power distribution systems rated 1 kV through 38 kV for the purposes of mitigating problems associated with power quality. This guide also includes definitions, general need guidelines, performance objectives, electrical environments, input/output criteria, performance measurements, case studies, bibliography, and engineering trade-offs. The proposed document addresses power assessment techniques as specified by IEEE Std 1250^TM-2011¹, which defines power quality terms and phenomena, and IEEE Std 1159^TM-2009, which provides a recommended practice for measuring power quality.

Purpose

This document provides guidelines and performance expectations for the application of power electronicbased equipment on utility distribution systems to improve power quality and control in these distribution systems. It can be a resource to utilities as they enter into the marketplace, providing detailed information about custom power devices as options to solving power quality problems.
