3203: Development of a Protective Coating Maintenance Strategy for the Above Ground Portion of Galvanized or Painted Steel Transmission Towers

Based on an industry survey of major international electric utilities and a review of relevantliterature, a state of the art of the current practices used for maintaining the above ground portion ofgalvanized or coated steel transmission structures is determined. Present methods for evaluatingtowers’ galvanizing and coating conditions are discussed. A software tool for estimating the cost ofapplying a protective coating system to a steel transmission tower considering different scenarios i

33144: Numerical Simulations of Cascade and Mitigation by Load Control and Load Reduction Devices (LCD and LRD)

The primary objective of the present research work is to develop a “user friendly software” based on numerical models to study the transient response of the conductor and its effect on the tower after a break. The transient response will be simulated with and without the load reduction (LRD) and load control (LCD) devices. At least several of these devices including sliding clamps will be considered in developing the model and response evaluations. The numerical model will be validated by using

03104: CPF: Establishing a Standard Methodology to Evaluate Start/stop and Cycling Costs and Impacts

Volume 1The following document describes a methodology to estimate the cost of increased starts and stops and other forms of variable operation at hydroelectric plants. This methodology was based on CEATI Report T152700-0391, titled “Effects on Hydropower Equipment from Variable Operations, with a Focus on Start/Stop,” which was supplemented over the course of this project (Greisen & Norlin, 2016). A methodology for estimating costs of starts and stops and other forms of variable ope

3249: CPF: Guide to Optimizing Transmission Line Asset Replacement

T133700-3249-1Due to the aging infrastructure of the power transmission grid, utilities are required to invest significantly in their assets to maintain the ability to provide uninterrupted power to their customers. Prior to committing their funding, utilities need to understand the financial impact of their investment, regardless of whether or not it requires the refurbishment or replacement of the aging asset. The primary criterion used in the evaluation of the value of each investment is dire

3272: CPF: Guidelines for Managing Transmission Line Clearances

The management of electric transmission line and rights-of-way clearances is a critical component of the safe and reliable operation of the North American power grid. It is also in the interest of national security in both the United States and Canada. Both ratepayers and stockholders are concerned with cost effective management and regulators are interested in maintaining one hundred percent system reliability 24/7. The utilization of industry best management practices is crucial for meeting th

0246: CPF: Translation of Structural Safety of Cracked Concrete Dams

The question regarding how state assessments of cracked concrete structures should be performed has since long been very interesting for the Dam Safety R&D program at Energiforsk. This report builds upon the project “Investigating the structural safety of cracked concrete dams” which was conducted by CEATI’s Dam Safety Interest Group (DSIG) in 2015, a project that the program proposed and supported.This study aims to develop a Swedish guideline for assessing status as well as c

3808: Monitoring the Operation of Mass Penetration Small Scale DER

Energy generation systems are in a transitional phase from traditional, centralized generation to decentralized, complex, customer-owned, and variable energy resources. As this transition occurs, visibility of small-scale distributed energy resources (DER) (which is defined as 5kW to 500 kW forthis study) becomes critical for utilities to maintain their key requirements of resiliency, reliability, safety, and affordability while adapting to emerging technologies. This report summarizes the best

3265: Transmission Line Switch Maintenance Strategies and Maintenance Requirements

Some transmission experts have concluded that the transmission line switch is the weakest link on the transmission grid; if they are not carefully installed and maintained, they will fail. Transmission-line switch maintenance is necessary and important for a reliable transmission system. Lack of maintenance can result in and increased number of failures and more costly repairs. At the same time, maintenance can frequently not be scheduled since transmission operational constraints do affect main
