33115: Innovative Visual Designs of Transmission Structures for Better Public Acceptance

The authors of this report evaluate the relationship between the inclusion of innovative new, visually-pleasing structures to improve public acceptance of constructing new transmission lines. Opposition to the construction of new transmission lines can negatively impact the project’s schedule, routing, in-service date and costs. This report characterizes and evaluates one factor motivating public opposition: the aesthetic value of transmission structures and the role it plays in public acc

0375: CPF: Hydraulic Unit Excessive Headgate Leakage Measurement, Prevention Methods and Materials

Safe work practices for working within a water passage, or on a generating unit, rely on intake and draft tube gate integrity. Gates should be able to seal well enough for the drainage system to maintain a safe water level without the use of sealing agents. For work to be carried out safely, the gate seal must be maintained for the duration of the work.To ensure the safety of personnel working within a confined space, methods must be in place to assess and control the volume of leakage past the

3240: CPF: Composite Poles in Transmission & Distribution - Experience and Issues

The Guide for the Use of Composite Poles, Cross Arms and Braces provides a comprehensive reference for the design, use and testing of fibre reinforced composite components such as structural poles, cross-arms and braces applicable for use in the electric power industry. As an integrated resource, the guide was first published in 2008 describing the general requirements for the manufacturing, design, assembly, erection and testing of composite structural shapes and connections for electrical tran

3510: Managing Cyber Security Risk and a Review of Protocols Used in Distributed Energy Resources

Cybersecurity for utility communications with distributed energy resources (DER) systems hasbecome increasingly critical for power system resilience as DER facilities proliferate andcommunications between DERs and utilities become necessary for planning and real-time gridsupport. Managing cybersecurity risks – whether from deliberate attacks or inadvertent errors orequipment failures – can be very complex, since DER systems are usually owned and operated bythird parties (aggregators

3347: Optimum Design Return Period of Overhead Lines Considering Line Failure Costs –A Guide for Utility Engineers

A simple optimization model is presented for a radial line configuration to compute the optimum return period. The optimization is done by balancing the initial line cost against the present value of the cost of losses due to line failures. The failure cost consists of two components: (1) expected cost of line replacement and (2) the expected cost of energy not supplied. It is shown clearly that the optimum design return period is significantly influenced by the duration of the line repair once

0330: Improved Flow Measurements for the Hydroelectric Power Industry

Hydroelectric power utilities and water resource agencies need accurate flow measurements to determine the unit efficiency characteristics that are fundamental to effective water resource management and economical operations. However, because the majority of hydro plants in North America are low head with short, convergent intakes, there is a gap between this need and ability in that neither the ASME test code nor the IEC test code currently deals specifically with the application of flow measur

0385: Electrical Overhaul Guide for Hydroelectric Turbine Generators

Increased demand for electric power, accompanied by environmental and financial constraints for new construction, inevitably calls for the full utilization of existing power generation assets. In the present socio-economic climate, water power is generally viewed as one of the most optimal renewable resources; being highly efficient, flexible, reliable, durable, and cost effective. However, despite the extended equipment life of hydro plants, roughly every twenty five years there is a need for r

5016: Evaluation of Refurbishment Options to Optimize Pole Replacement

Three types of steel stubs were evaluated through destructive testing for their effectiveness in groundline refurbishment of distribution size wood poles. The effectiveness of the mechanism for banding and bolting the stubs to the poles in the transferring load was examined. Destructive testing was carried out to investigate the impact of woodpecker damage on the load-carrying capacity of distribution size poles. Three repair products were applied and evaluated, testing the structural integrity

0135: Impact of Cycling/Two shift Damage on the O&M Cost and Reliability of Natural Gas-Fired Combined Cycle (NGCC) Power Plants

The on-going privatization of electricity generation across the world, competition, and demand by shareholders for higher profits, stricter regulations on environmental impacts and the increasing penetration of non-dispatchable energy have resulted in an increasing need for larger energy generators to operate as non base-load units. As a result, Natural Gas-Fired Combined Cycle (NGCC) Power Plants are increasingly being subjected to load-following and/or cyclic operation. However, cyclic operati
