Power Quality Studies, Harmonic Analysis & Solutions
"Power Quality (PQ) is a highly newsworthy issue"
Increasing use of semiconductor based electronic equipment & non-linear loads (such as SMPS used in computers & their peripherals, data servers, variable speed drivers (VFD), arc furnaces, LED lights etc.) and rapid integration of non-conventional energy sources into grid network throws new challenges for the PQ environment.
The characteristics of electricity like frequency, magnitude, waveform, and symmetry are subject to variations during the normal operation in a supply system due to changes of load, disturbances generated by certain equipment and the occurrence of faults which are mainly caused by external events. Sometimes the equipment installed at the premises of an electricity user can inject disturbances (e.g. harmonic or inter-harmonic distortion, voltage fluctuations etc.) into the distribution networks.
These power quality issues may affect end users, equipment & system manufacturer, designers of plants & installations, electricity distributors, public authorities and the public. The outcome of some surveys has revealed significant losses to industries due to poor power quality. Variation in voltage & frequency and waveform distortion (in other words harmonics) are the critical power quality issues.
Emicon offers a broad range of engineering services in power quality such as:
1. Site surveys, on-site power quality data logging using Fluke instrument, harmonic analysis and recommendations.
2. Detailed study of reactive power, power factor and existing harmonic pattern in the electrical system.
3. Design & recommend optimal solutions based on measured project data. Simulation of the electrical network, the system using ETAP software and carrying out harmonic penetration studies.
4. Solutions to improve power factor and mitigate harmonics as per IEEE 519 standards.
5. Implementing the recommended solutions and verifying the results by doing re-analysis to ensure optimized system performance with the fastest payback.
6. Turnkey PQ project; design, installation, programming, testing and commissioning of harmonic mitigation equipment such as active and passive harmonic filters, SVG’s etc.
7. Review, approval and procurement advice of different manufacturers’ PQ equipment such as AHF, SVG, Capacitor Bank etc. including comparison study by meeting the requirements of the project, client and local authority’s regulations and Int’l standards.
