An Assessment of Distribution System Power Quality is the most extensive distribution system power quality monitoring study ever commissioned. The project, commonly referred to as the {open_quotes}DPQ Project{close_quotes}, was begun in the fall of 1989. Its primary goal was to collect, analyze, and report on distribution system power quality data at a national level with a degree of statistical importance. The twenty-seven month monitoring effort resulted in the collection and processing of over thirty gigabytes of power quality data, that now reside in the primary product of the project, the DPQ Database. Additional findings include guidelines for monitoring and modeling distribution system power quality events, and a library of monitoring case studies. Power quality is one of the most important concerns facing electric utilities today. The increasing dependence on sophisticated electronic controls and automated manufacturing within customer facilities is resulting in a requirement for higher levels of reliability and power quality than were ever previously needed. The problem is compounded by the fact that customer equipment has become more sensitive and is now interconnected in extensive networks and processes. The result is that variations in the power quality that were never a concern can now be very expensive in terms of process shut-downs and equipment malfunctions.
