Title: Distribution System Power Quality Assessment: Phase II: Voltage Sag and Interruption Analysis Role: Project Manager Published: March, 2003 Description: The quality of electricity service required by customers of all classes is increasing. This requirement for increasing quality is due to many factors, including increasing sensitivity of the devices used by customers and their awareness of the impacts of small variations in the quality of the electricity supply. In the early 1990s, EPRI initiated a project called the Distribution Power Quality (DPQ) Project, which resulted in power quality monitoring at 277 distribution sites statistically chosen throughout the United States to gain valuable knowledge regarding the frequency and severity of power quality events. This report presents the finding of a follow-on project, referred to as DPQ II, which was conducted in 2001 and 2002. This project resulted in characterizing power quality in terms of short-duration variations such as voltage sags, voltage swells, and voltage interruptions. The characterization was based on analysis of data from 480 power quality monitors at different locations in a power system spanning a date range from August 30, 1993 through December 12, 2002. The results of the analysis that are presented in this report provide a unique opportunity to understand the electrical environment in terms of short-duration variations and further validate the findings of DPQ I.

Title: Evaluation of Wireless Communications Technologies for Improved Power Quality Data Transfer Role: Project Manager Published: February, 2003 Description: Traditionally, power quality data transfer has been done using serial connections either direct or via modems. While the rest of the world has been caught up in a communications revolution, PQ monitoring data transfer has not kept up with communication technology. Wireless data communications have become ubiquitous during the last several years. Delivering anywhere, anytime access to vital information, wireless technologies such as IEEE 802.11 are reshaping the way data is transferred and shared. This reports attempts to show that adapting wireless communications to power quality monitoring is both practical and desirable.

Title: Power Quality Monitoring Data Mining for Power System Load Modeling Role: Investigator Published: December, 2003 Description: This report describes the potential for mining power quality (PQ) monitoring data to develop parameters that utilities can use in power system load modeling. The topics covered in this report include a brief overview of emerging load characteristics, PQ monitoring data characteristics and their applicability for use in load modeling, and methodology for using PQ data to evaluate parameters for static load modeling. The report also describes the concept of a fast voltage collapse index (FVCI) to identify potential weak locations in a power system with significant air-conditioning loads, and an algorithm to compute site-specific FVCI using RMS variation data available from a PQ monitoring system.

Title: Premium Power Grades: Developing Site Selection Criteria for DPQ Phase II Role: Project Manager Published: February, 2002 Description: With the proliferation of embedded processors and other sensitive digital loads, the need for increased understanding of power quality (PQ) event characteristics in electrical power systems has never been greater. Since the completion of the EPRI Distribution Power Quality (DPQ) project in 1995, several utilities have implemented system-wide PQ monitoring programs both in distribution and transmission systems. The wealth of data collected since the DPQ project provides a unique opportunity to synthesize meaningful information regarding variability of grid power -- specifically on voltage sag rates -- based on system characteristics. It also presents a unique opportunity to compare DPQ project results with data from these monitoring programs. This report develops the framework for conducting a second-round DPQ project, using existing data collected by utilities with permanent power quality monitoring systems.

Title: Power Quality Data Interchange Format (PQIF) Software Verification and Demonstration Test Bed for Power Quality and Advanced Revenue Meters Role: Project Manager Published: November, 2001 Description: The power quality data interchange format (PQDIF) is a digital file format developed to provide a standard for exchanging power quality data, independent of manufacturer. PQDIF is a proposed Institute of Electrical and Electronics Engineers (IEEE) standard (P1159.3). Manufacturers of power quality monitors and other metering devices are working to conform to this standard by providing PQDIF data export capability in their equipment. Both manufacturers and potential users of PQDIF have expressed interest in a test procedure that could verify and validate the ability of the power quality monitoring system suppliers' software and/or hardware to produce valid PQDIF files. This EPRI project provides a test procedure and an independent test facility for verifying and validating PQDIF files.

Title: Survey Methodology for Statistically Valid Sampling Procedure: Monitoring Residential Power Quality Role: Princiapl Investigator Published: September, 2000 Description: A majority of work performed in the power quality arena has focused on utility power quality and its effects on industrial and large commercial customers. Monitoring projects have been undertaken to characterize power quality levels at the utility distribution level and to some extent the industrial customer level. Due to the advances in electronic consumer products and the new digital market place, more and more residential customers are purchasing computer-based appliances. Many of the traditional residential loads such as heating and air-conditioning equipment, washers and dryers, stoves and cook tops, and audio/video equipment now have microprocessor-based technology incorporated into their designs. These microprocessor-based appliances require a better grade of power than their predecessors. Utilities, appliance manufacturers, and residential customers have all expressed a need for information relating to residential power quality. This report describes the process used to develop a methodology for performing a system-wide residential power quality monitoring project. It addresses the need for power quality data as well as the process that must be undertaken to ensure a statistically valid data set. Information pertaining to the types of power quality events that affect customers is presented along with information on where, how, and when to measure power quality at a residential facility.

Title: Transmission Power Quality Benchmarking Method Role: Principal Investigator Published: December, 2000 Description: In 1990, EPRI initiated a power quality monitoring project at the distribution level known as the EPRI DPQ Project. During this project, twenty-four utilities monitored power quality levels on their distribution circuits. Nearly 300 sites were monitored for a period of approximately two years. The data gathered were characterized and analyzed to form a baseline of power quality on U.S. distribution circuits. As interest in the results of the DPQ Project grew, utilities around the world began to participate in national and individual studies to benchmark power quality at the distribution level. However, considerably less effort has been directed at benchmarking power quality at the transmission level. Several reasons among many for this situation include the relative proximity to the end user, the additional costs of monitoring at the transmission level, and the fact that transmission-level events are indirectly included in distribution assessments. The practice of serving large, influential customers from transmission systems continues to grow, and the traditional vertically integrated utility is unbundling into three companies: generation, transmission, and distribution. Utilities, therefore, have become aware of the need to benchmark the power quality performance of the transmission system separately from the performance of the distribution system.
