0359: CPF: Hydraulic Station Headgate Testing Protocols

The ability to shut off flows at hydroelectric generating power stations is necessary for safe and reliable facility operation. While most hydroelectric stations have wicket gates as the primary operating turbine water shut off device, the majority also have headgates that allow dewatered turbine maintenance. Many of these headgates also serve as a backup if the turbine wicket gates fail to properly close.Testing the gates and their operating and control equipment is one of the best methods of c

3396B: Corrosion Manual on Steel Towers and Grillage Foundations

While structural material degradation due to corrosion is inevitable in aging electric utility structures, it is crucial to identify corrosion-related issues and select and apply proper corrosion mitigation methods before corrosion damage compromises the structural integrity of the assets. Considering the increasing competition within the energy market, corrosion management ― among other asset maintenance efforts ― has emerged as a major financial challenge for electric utilities that own and ma

0250: Enhanced Surveillance and Monitoring Techniques for Concrete Dams: Performance-Based Testing and Analysis of Mossyrock Dam – Identifying Behavioral Characteristics and Performance Indicators

This two-part report provides details on the use of flow-induced monitoring (FIM) and Performance-based Testing (PBT) techniques using behavioural characteristics of Mossyrock Dam as a case study/example. Report one is specific to the work, investigations, and analyses carried out at Mossyrock Dam; the second report uses the findings from Mossyrock as a guide to help dam owners improve their ability to monitor, track, and detect existing and changing conditions in their dams.Descriptions of the

3501: Practices & Products for Securing the Perimeter of Electrical Transmission Stations

Perimeters of stations containing high voltage apparatus are secured to protect the public from high hazard areas and to protect valuable station assets from theft, vandalism, mischief and sabotage. The electrical utility industry has made good progress towards improving perimeter security as threats and risk have increased. New developments in perimeter security systems and practice are continually assessed with a view to applying appropriate solutions to further improve the security of electri

0543: How Low Can the Cost of Solar PV Go?

This report provides a literature review and analysis into potential changes in the cost of solar PV between a 2017 base year and the year 2030. The key question that this study answers is whether falling PV system costs are likely to make load and/or grid defection from existing utilities economically attractive. This analysis is conducted via an excel workbook that includes a wide range of assumptions on the cost and performance of a typical PV system deployed in four (4) North American locati

50154: Innovative Techniques to Reduce O&M Costs

The pressure to reduce costs and improve utility operations is ever present. Innovative concepts are regularly presented, and each comes with the same question: “Does this apply to us?” This report examines some of the innovative techniques currently being evaluated by utilities.Innovations are often presented from a vendor or service provider point of view with little evidence of effectiveness from utility experience. Therefore, there is a need for utilities to share experiences wit

3078: Station Equipment Condition Parameters

This report presents the results of a bench marking survey prepared by the LCMSEA Interest Group of CEATI International. The survey is intended to identify the non-condition and condition based assessment indicators member utilities are using for condition assessment of station equipment including the relative weighting applied to each indicator used in their condition assessment programs.Assessing the condition of the equipment in a station is a crucial component of a utility’s maintenanc

3103: Commitment Techniques for Combined-Cycle Generating Units

The purpose of this document is to present the optimization methodologies that are currently suggested to solve the Security Constrained Unit Commitment (SCUC) problem, and the ways of considering combined-cycle units when using those methodologies.The report summarizes the major techniques used for the SCUC, including Lagrangian Relaxation, Bender Decomposition and Mixed Integer-Linear programming. A summary of operating characteristics of the combined-cycle generating units (CCGU) is presente

50152: Detecting High Impedance Faults on Overhead Distribution Systems

High impedance faults (HIFs) are short-circuit faults that do not produce sufficient fault current and are thus not detectable by traditional overcurrent protection schemes. Research on HIF detection has been ongoing since the 1970s. Unfortunately, progress has been slow due to the complexity of HIF characteristics. This project conducted a comprehensive survey on the characteristics of HIFs and various HIF detection techniques. The techniques can be broadly classified into three types: 1) techn

03102B: CPF: Guide to Ensuring Quality for Manufacturing and Installation of Hydroelectric Plant Equipment: Equipment Application

This guide provides a basis for an owner’s quality assurance program for the supply and installation of electrical and mechanical equipment for hydroelectric plants. It does not include quality information for civil works.Part A described the need for and basics of a quality program for equipment supply and installation for a typical hydroelectric project. It outlines the processes and systems needed for a quality assurance program. A quality assurance program involves both supply and inst
