0358: Short Converging Intake Comparative Flow Rate Measurement Tests at Kootenay Canal

Hydroturbine efficiency testing is important for acceptance tests of new turbines, power and water sharing agreements, and optimal dispatch of generating units. The measurement of flow rate is a key component of efficiency testing. However, the major standard test codes do not allow any practical means for measuring flow rate in one of the most common hydroelectric configurations, the low-head Kaplan unit. These units are characterized by a short converging intake that lacks the long uniform wat

0339: CPF: On-Line Cavitation Monitoring

Cavitation erosion repairs require long periods of outages that limit hydropower generation. In a competitive marketplace, utility operators strive to maximize power and energy from every unit. Although current tendencies are to design new runners with lower cavitation, commercial operation is often far from optimal turbine efficiency. There are on-line cavitation monitoring technologies available on the market as well as others that have been developed in-house by utilities. These technolo

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

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

0370: CPF: Grounding and Bonding Best Practices

Hydraulic generating stations include features that call for special grounding considerations, in addition to those usually present at transformer stations. This report provides information on the design, construction, maintenance and system assessment of grounding systems in, and around, hydroelectric generating stations and associated switchyards. It also includes material to help staff review submissions for new and modified installations, whether designed by employees or others.&

0316: CPF: On-Line Monitoring Systems: Assessment Report

To survive in today’s challenging marketplace, you need access to the right information – at the right time. Shrinking margins, higher production costs and the expense of regulatory compliance all squeeze profits. Survivors find new ways to improve productivity and safety.One key to survival is an advanced on-line monitoring system. In fact, one of the most data-intensive activities in many hydro plants is gathering data on unit operating parameters.

0349: Identification of Hydro Performance and Production Problems Including Start-Stop Operations

As a result of a continually changing operating environment for hydroelectric generating (hydro) assets, the Hydraulic Plant Life Interest Group (HPLIG) and other groups have been monitoring the reliability and availability of assets within their purview, looking for a broader comparison of reliability reporting systems, potentially for standardization, and also looking for relative performance assessments of units on a broader comparative basis.Additionally, asset owners are keenly interested i

0355: Best Practice Guide for Planning and Executing Hydro Overhaul and Retrofit Projects/Optimization of Rehabilitation

Building new hydro plants has become increasingly difficult in many jurisdictions due to financial,social and environmental considerations. Existing hydropower, however, has gained a significantadvantage in new electrical markets as a flexible, low-cost and environmentally sustainable resource.Overhauling and retrofitting existing plants to extend life and increase output, where economicallyand technically feasible, often makes excellent business sense.Technical knowledge on overhauls and retrof
