本指南的读者将找到有关识别和改善电力系统电能质量的方法的讨论，以及该领域出版物的参考资料。更具体地说，本指南包括以下内容: a） 基准研究得出的电能质量水平 b） 影响电力系统性能的因素 c） 改善电力系统性能的缓解措施 d） 参考当前相关的深入IEEE标准和其他文件 本指南仅针对没有其他电能质量参考文献的主题进行深入探讨。这是a吗？网关？电能质量文件，为该领域的其他文件指明了方向。

The reader of this guide will find discussions of ways to identify and improve power quality in power systems, as well as references to publications in this area. More specifically, this guide includes the following: a) Power quality levels from benchmarking studies b) Factors that affect power system performance c) Mitigation measures that improve power system performance d) References to current relevant in-depth IEEE standards and other documents This guide only addresses subjects in depth where no other power quality reference does so. It is a "gateway" document for power quality that points the way to other documents in this field.
