Standardization of Harmonic Levels

3.1    Introduction

The most widespread standards for harmonic control worldwide are due to the Institute of Electrical and Electronics Engineers (IEEE) in the United States and the International Electrotechnical Commission (IEC) in the European Union. In 1981, the IEEE issued standard 519-1981,1 which aimed to provide guidelines and recommended practices for commutation notching, voltage distortion, telephone influence, and flicker limits produced by power converters. The standard contended with cumulative effects but did little to consider the strong interaction between harmonic producers and power system operation.

The main focus of the revised IEEE 519 standard in 19922 was a more suitable stance in ...
