Harmonic Analyses Study at OPD, Psychiatry
Building, PEC, Wakrah Dialysis and FBJ Dialysis Center in Hamad Medical Corporation Hospitals, Qatar

The project addresses power quality effects on the distribution system facilities within considered Hamad Medical Corporation (HMC) hospitals. The project activities site survey, measurements of power quality parameters and report on the power quality effects on the hospitals’’ distribution system facilities.

he site survey included review of existing electrical equipment and facilities. Relevant information, data and drawings has been collected from the visited sites. Operating status of installed equipment has been assessed. Available statistical data from the service records has been compiled (load demand records, missing equipment data, etc.). Interviews with relevant personnel, responsible for operation and service of distribution system, has been carried out during site survey activities. This helped Energoprojekt ENTEL to determine actual status of considered distribution system as a basis for further study activities. Based on the collected information and other data ENTEL established collective data base including all relevant information necessary for study execution.

Harmonic measurements have been conducted using a power quality analyzer (HIOKI 3196) so as to determine harmonic spectrum at the site. The power quality analyzer recorded various system (power quality) parameters such as power factor, total voltage/current harmonic distortion, particular voltage/current harmonics, active power, reactive power, apparent power, voltage and current. Based on obtained results further measurements have been conducted for a shorter time but greater sampling rate at particular locations in downstream network.  The results of measurements are used as common input for study of harmonic distortion within considered network.

Based on all of the above, Energoprojekt ENTEL prepared the Study of power quality effects to the distribution system, caused by existing equipment installed. Analysis of harmonics and other power quality parameters along with necessary calculations have been carried out. These values have been compared with limits prescribed by international regulations and standards defining permitted levels. In addition, a detail report with recommendations for solving the problems was prepared.
