摘要
Power quality is a compatibility issue between the supply systems and the connected loads. It is often considered as a customer-side problem as its significance depends primarily on the sensitivity of the affected equipment and its function. Improvement solutions are implemented by or on behalf of the customers only if the negative impact is causing great financial losses. However, as the reliance on electronic devices continues to increase unabatedly, the percentage of equipment being affected is expected to grow appreciably. In due course, the number of affected equipment could be so large that it is only practical and economical to implement universal solutions instead of individual solutions. This paper provides an early view of this scenario and explores the various elements necessary for reining in the poor power quality, widely expected to deteriorate further following deregulation of power industry. It attempts to use the free market oriented approach so that solutions implemented are justified on economical basis.
