Performance evaluation of distribution network - power quality approach

In the modern era power quality has become a serious issue due to ever increase in use of Non linear loads i.e. variable speed drives, power electronics gadgets etc. The IEEE 519 guidelines deliberates the concept of powering equipment in a manner that is suitable to the operation of that equipment. This paper explains details of quality of power supplied and handled by the equipments at the distribution substation, to know the status of the substation equipment; which are mainly responsible for the power quality, The reality check of substation losses and the compatibility of distribution network with standard of performance for reliability improvement of electrical system and network. Means adopted for loss reduction, Overview of various power quality parameters. The best possible solutions to the power quality problems are discussed and their practicable functioning is discussed. The solutions present in the field are explained and field results are presented. Emphasis has been given to explain that by using proper technology a various power quality problems can be addressed.
