UNDERSTANDING AND APPLYING THE SPIRIT OF IEEE 519-2014
Energy efficiency should remain at the core of all power system designs. This fundamental principle has been lucidly explained and forms the spirit of the latest guideline on harmonics published by the IEEE. The older recommendations set in IEEE 519-1992 was confusing and subject to different interpretations, depending on one’s background and responsibility. The latest document rightly stresses energy efficiency. Reading in between the lines, one gets a feeling that the document encourages one to strive to reduce the overall carbon footprint of a given system. The introduction of statistics in the latest rendering of the IEEE 519 document is extremely important because by introducing the concept of time in the measurement method forces one to think about long term effects of current harmonics and poor power factor on energy wastage and plant efficiency. The point in the power system where statistical data should be measured and collected has also been clearly described without any ambiguity. This point, often referred to as the Point of Common Coupling (PCC) is clearly defined to be a point on the public utility system and not in front of a specific individual power converter. The webinar hopes to bring out the salient points in the new IEEE 519-2014 document and will try to contrast it with the older IEEE 519-1992 document wherever possible. The reasons and technical justifications for the much improved IEEE 519 document will be given. The webinar will also discuss some smart and cost effective ways of improving the overall system power factor, reducing input current and voltage harmonics and reducing system losses so as to help achieve the intent set forth in the new IEEE 519-2014 guideline.
