The paper presents results from an application of series tuned harmonic filter banks to reduce voltage harmonic distortion in a large chemical plant. Harmonic field test data, harmonic analysis, and power flow analysis were used to properly design the filters. Power quality on the system, filter design factors and comparison of voltage distortion between simulations and the electrical system with installed harmonic filter banks are also discussed. Finally, various aspects of the project are documented, including harmonic field tests and application of the harmonic filters with large rectifier loads.
