Need for greater regulatory intervention in ensuring quality of power supply and adherence to standards have been under consideration of India’s FORUM OF REGULATORS (FOR).APQI commends FOR for bringing out a comprehensive report on “Power Quality of Electricity Supply to the Consumers” along with prescribed “Model Regulation on Power Quality for State – Applicable for Distribution System”.
Electric power quality (PQ) disturbances can have significant economic consequences for many different types of facilities. Although power quality is widely recognized as an important issue in Europe as well as in the USA, there is limited knowledge of PQ in Southeast Asia (SEA).
International Copper Association India (ICAI) with the support of KEMA presented a report on power quality (PQ) in India and to increase the awareness of policy makers and regulators. Assessment of current power quality level in India. Provided that sufficient relevant data is available, the level should be preferably expressed in grade based power quality categories.
To capture the impact of power quality problems on Indian industries, a survey questionnaire was prepared and sent to different industrial sectors which are electricity intensive such as Textile, Chemical and Fertilizers, IT sector, Iron and steel, Paper and pulp, Metallurgy, Manufacturing sector for electronic goods, universities/ institutions, Commercial sectors such as banks, hospitals and shopping malls.
Power quality is gaining importance due to increased usage of power electronic technology.Many power converters are being used for control of machines and drives, energy conservation, power conversion for heating & welding applications and also for electronic appliances like computers, television and other medical electronic systems.
In this paper, the main Power Quality (PQ) problems are presented with their associated causes and consequences. The economic impacts associated with PQ are characterized. Finally, some solutions to mitigate the PQ problems are presented.
