A new paper submission to EPQU magazine. Download paper in review.

The growth in power electronics has impacted many loads that traditionally were considered linear in nature. As a result, the number of nonlinear loads has increased and is expected to increase dramatically in the years ahead. With increasing quantities of non-linear loads being added to electrical systems, it has become necessary to establish criteria for limiting problems from system voltage degradation.

This paper presents the power quality problems, issues and related international standards. The presentation is done with giving a thorough knowledge of harmonics, power quality indices, parameters effecting electric power etc. Latest research work in giving different international standards for different type of power quality problems is also been given. This is important for design engineers and researchers in power quality to know the international standards used for power quality.

Design and Analysis of Supercapacitors Energy Storage System for Energy Stabilization of Distribution Network Design and Analysis of Supercapacitors Energy Storage System for Energy Stabilization of Distribution Network Hans De Keulenaer Supercapacitors are the devices which can be store significant amounts of energy and quickly release it, their main application is for short term power compensation application where they can release a large amount of energy quickly and then can be recharged with smaller current. In this paper the use of supercapacitors bank is explored for energy stabilization and maintaining the voltage profile of the distribution system at the load point. The proposed supercapacitor bank is designed to improve the voltage profile of a distribution system by supplying the energy in case of demand and recharging the supercapacitors bank in valley period. The designed bank is of 50 kWh(180 MJ) of energy, 440 V voltages and peak power of 30 kW capacities for supply of energy in case of instantaneous need. The result shows that the SCESS can supply the instantaneous power for the back up the loads even though the voltage may drop up to 100 V; this SCESS can back up the load from 1.60-9.9974 hours depending upon the power demand while maintaining the minimum discharge voltage ratio and availability of useful energy

Transcript

1. Membership

  • remove 3 dormant members from the board
  • ask for replacement candidates (Italy, FYROM via Jovica, Slovenia (A Gubina), India (IIT Mumbai))

2. New EPQU website

3. Plan for issue 4/1

  • Expert interview Helge on PQ regulation @ distribution level
  • EN 50160 measurement campaign – problems with flicker, IEC 61000-4-30 (discussion webinar)
  • chindris: we could send a paper regarding some experimental measurement in a plant in Romania

4. Ideas for issue 4/2

  • Approach CIRED on PQ session (find CIRED participant from Board, or ask for CIRED recommendation)

5. Any other topics

  • 20 take-ways in 20 minutes
  • Technical aspects about res deployment; deep versus shallow charging; network reinforcement

6. Next meeting

Monday, June 22, 15h30 – 16h30

Next EPQU editorial board session (all timings GMT+1 – Brussels)
( polls)

Next EPQU editorial board session (all timings GMT+1 – Brussels)
( surveys)

  1. The editorial board is comfortable with the current setup and processes of EPQU Magazine.
  2. To justify the effort, the number of subscribers (currently around 1,500) needs to be increased. Also, a survey will be organised to characterise current readership and ask for their expectations.
  3. Ideas for volume 4 – issue 1 are listed below. The board will work over the coming months to identify topics & authors for the issue. This process will run in parallel with the call for papers. By middle of February, we should have an outline for the issue. Papers should be submitted by end of March at the latest. Volume 4 Issue 1 closes end of April.
  4. The next webmeeting of the editorial board will be February 2009, to discuss the outline of the next issue, and the outcome of the reader survey.
