5139: State of the Art Sensors Suitable for Distribution Automation Applications

Growing service quality expectations make the Distribution Automation (DA) processes increasingly imperative for power utilities and may trigger the next major step in the evolution of the distribution system. A successful distribution system management activity, such as DA, hinges on the information collected from the network using an integrated monitoring system. It enables real-time monitoring of grid conditions for distribution system operators and allows automatic reconfiguration of the net

5122: Survey and Assessment of Techniques for Locating the Sources of Voltage Sag Disturbances

This report documents a comprehensive survey and assessment of the methods for locating the sources of voltage sag disturbances. Its objective is to determine the performance characteristics of the most promising sag source detection methods through independent theoretical analysis and case studies. The findings will serve as a guide for utility engineers to choose proper methods for voltage sag problem diagnosis. Based on the extensive survey conducted for this project, four most promising me

0363: CPF: Quantifying the Non-Energy Benefits of Hydropower

North American hydro power owners have historically been competing in a world of relatively inexpensive carbon-fuelled electricity from coal and gas. New U.S. energy policies on the licensing and operation of hydro plants have been increasingly trading energy and ancillary benefits of hydro for non-energy benefits including difficult-to-monetize benefits for endangered species and fish passage. Many small hydro projects have non-energy benefit costs that exceed the value of the energy generated.

0407: Evaluation of the Shallow Water Ice Profiling Sonar for Measuring Frazil Ice

The Shallow Water Ice Profiling Sonar (SWIP) is an upward looking sonar that was designed for studying river ice, specifically designed to investigate suspended frazil ice, formation of ice pans and seasonal ice cover.The objectives of this project were to expand and improve the measurement capabilities of the SWIP for the measurement of frazile ice through laboratory testing of the correlation between between the amplitude of the backscatter acoustic pulses and the frazil ice concentration.

0542: Leveraging Fast-Ramping Capabilities Beyond Frequency Regulations

Increasing adoption of distributed energy resources (DERs) and grid-scale variable renewable energy is resulting in a growing demand for technologies that can rapidly ramp up and ramp down electricity generation to match electricity demand. Although various mature and upcoming technologies that provide these ancillary services are currently part of market mechanisms and have well-defined physical as well as economic characteristics, fast-ramping capabilities available in some of these technologi

0206: Static Ice Loads On Hydro-Electric Structures - Summary Report, Ice Load Design Guide, and Ice Load Prediction Computer Program

A ten-year project was undertaken in which field programs were conducted over a nine-year period from 1991-92 to 1999-00 to: (a) measure the loads in the ice sheet near the dam; (b) measure the load distribution between a gate and pier, and: (c) compare the loads on wooden and steel stoplogs. Parallel work was conducted to develop analytical predictors for ice loads. An environmental model was developed which compares well to the measured data. An Ice Loads Design Guide was produced, synthesizi

0205A: Investigation of Geophysical Methods for Assessing Seepage and Internal Erosion in Embankment Dams: A Parameter Study for Internal Erosion Monitoring

T992700-0205A. A Parameter Study for Internal Erosion MonitoringThis volume marks one of a series of reports on the subject of geophysical methods and their usein assessing seepage and internal erosion in embankment dams. These reports are available both separately and as a package.The objective of dam monitoring is to obtain key information about the dam safety status and itis therefore essential for dam owners. The most common monitoring methods are seepage and pressure, which sometimes d

0535: PEV Deployment: Policy Paper from Utility Perspective

The introduction of a large number of PEV loads to the Canadian electricity grid could lead to a number of technical bottlenecks ranging from localized to utility-scale effects. Many policymakers and stakeholders in the utility industry are seeking to understand these potential effects and to assess the risks associated with them before a large-scale roll-out of PEVs occurs in their regions. Although the physical effects of PEVs on the electricity grid are important to examine in detail, appropr

3043: Review and Summary of Key Standards and Guides for Station-Class Power Transformers

This project was developed to help utility engineers quickly identify and review the key standards and guides applicable to specific topics being faced by utility staff. Key standards and guides related to station liquid-filled power transformers have been identified and summarized. Key topics and sub-topics relevant to power transformers have been developed and related to each of the summarized standards (using a relevance matrix). A comparison of North American and worldwide standards has been

5030: Improved Performance of Switched Capacitor Banks

A review of available technologies was undertaken to determine if there are economical methods for monitoring and detecting out-of-service capacitor banks in non-SCADA equipped systems, and whether the installation of such systems can be economically justified.
