5164: Power Quality Reference Brochure (Guide) – For Customers and Utility Representatives

This brochure is intended to serve as a quick reference guide for utilities and their customers on identifying common power quality problems and their causes, and how to select appropriate power conditioning measures. This guide includes a review of some of the most important power quality phenomena, including voltage unbalance, voltage sags and swells, momentary interruptions, transients, switching surges, harmonics, notching, and voltage flicker.A section on best practices for characterizing a

3803: Interfacing DMS/OMS/SCADA Systems with Enterprise Business IT Systems for IT/OT Integration in Smart Grid.

In recent years, several utilities have implemented a Distribution Management System (DMS), SCADA, and undertaken new installations or upgrades to their Outage Management System (OMS). With the primary goals of achieving distribution system automation, reliability improvement and faster restoration times, these projects have led to significant efforts in integrating Operations Technology (OT) and Information Technology (IT) systems. This so-called IT-OT integration has presented challenges that

3219: Life Cycle Cost Analysis

In order to stay competitive, electric utilities are required to invest in the upgrade and expansion of their infrastructures to provide services to an increasing customer base. Since these projects require significant investments, utilities are increasingly interested in accurately identifying the initial construction cost and maintenance costs in order to determine the lowest life cycle cost and the total cost of ownership. In this report, an integrated model is presented which consistently

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

3116: CPF: Dynamic Loading of Power Lines to Increase Transmission Network Capacity

Transmission network capacity is limited by line voltage and by the ability of the conductors to carry current, known as ampacity. While system voltage tends to be fixed, the line currents are inherently dynamic with fluctuations in response to customer loads and internal system configuration. Additional transmission network capacity can be obtained in some cases by increasing the ampacity of lines through the use of improved survey and monitoring methods. Some utilities have more than twenty ye

0150: Optimization of Natural Gas Fired Combined Cycle Gas Turbines CCGT Power Plant Modifications to Improve Cyclic Performance

The study provides information on plant improvements for 20 to 25-year-old 2x1 F-class type CCGT facilities that were originally designed for base load operation and are now cycling daily or twice daily. Emphasis is on steam turbine (ST) and HRSG improvements that reduce cyclic failure mechanisms that cause component failures. Recommendations are provided on groups of improvements based on OEM or third person specialize contractor (OEM-TP) involvement, balance of plant (BOP) improvements, cost o

5144: Using Distributed Generation in Power Quality Configurations

This report provides new perspectives on how distributed generation (DG) can be applied in ways that enhance both power quality (PQ) and reliability, given the right situations and configurations. To support these new perspectives, the report outlines the background and the methodology needed to understand and quantify distributed generation value propositions, by evaluating the power quality enhancement benefit afforded by such technologies and then describing the best options to achieve these

3420: HPFF Joint Casings Corrosion Protection Aging Test

High-pressure fluid-filled (HPFF) cables are the most widely used pipe-type electrical transmission line, accounting for 80% of all underground transmission lines [1-4]. Corrosion is a primarily concern for pipe-type cable systems, specifically regarding the cable pipe. Steel pipelines can corrode if they come into contact with water and salts in the soil. If the surface of the pipeline is damaged, corrosion is likely to occur, resulting in the leak of the fluid contained between the pipeline an
