Guide for Identifying and Improving Voltage Quality in Power Systems

This guide discusses ways to identify and improve power quality in electric power systems. Furthermore, the guide provides references to publications in this area. The guide includes the following: a) Power quality levels on electric power systems from benchmarking studies; b) Factors that affect electric power system power quality; c) Mitigation measures that improve electric power system power quality; and d) References to current relevant in-depth IEEE standards and other documents. This guide addresses power quality topics in depth where no other IEEE standard does so. It is an introductory document for power quality topics in electric power systems.

IEEE Guide for Identifying and Improving Voltage Quality in Power Systems

The use of some electrical equipment attached to typical power systems creates power quality concerns. There is an increasing awareness that some equipment is not designed to withstand the surges, faults, distortion, and reclosing duty present on typical utility distribution systems. Traditional concerns about steady-state voltage levels and light flicker due to voltage fluctuation also remain. These concerns are addressed by this guide by documenting typical levels of these aspects of power quality and indicating how to improve them. Other documents that treat these subjects in more detail are referenced.

IEEE Guide for Voltage Sag Indices

Appropriate voltage sag indices and characteristics of electrical power and supply systems as well as the methods for calculating them are identified. Methods are provided for quantifying the severity of individual voltage sag events, for quantifying the performance at a specific location (single-site indices), and for quantifying the performance of the whole system (system indices). Multiple methods are presented for each. The methods are appropriate for use in transmission, distribution, and utilization electric power systems.

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
