Real experience using power quality data to improve power distribution reliability

Reliability has always been the central focus of network operators. However, today they must also focus on sustainability and efficiency. The ever increasing use of intermittent renewable energy sources and the need to reconfigure the network based on efficiency seem to counter the quality of supply standards set forth by regulators. Maintaining the balance between quality, reliability and efficiency requires new tools for the network operator. This paper describes a system that utilizes various methods for monitoring and reporting power quality information to help utilities maintain the balance of quality, reliability, and efficiency. Examples of real-world uses are given as well as quantified benefits where available.
