Harmonic Studies

Harmonic studies of utility systems determine the effects of harmonic-producing devices such as furnaces, large adjustable-speed drives, static VAR compensators, and HVDC rectifiers on other equipment in the system, to determine potential resonance issues. These studies are typically associated with the installation of capacitor banks or reactors, and for designing and evaluating the performance of harmonic filter banks.

Harmonic studies of industrial, commercial, and institutional facilities evaluate harmonic voltage and current distortion at the point of common coupling with the utility to ensure compliance with IEEE Standard 519, and also evaluate the effectiveness of harmonic filter banks.

Harmonic studies are performed using CYME International’s Power System Analysis Framework-Harmonics or the Alternative Transients Program, which is the PC version of the Electromagnetic Transients Program. Analysis is based on the recommendations in IEEE Standard 519-1992, Recommended Practices and Requirements for Harmonic Control in Electric Power Systems.
