This session provides a baseline understanding of Smart Grid and the activities that it encompasses including interoperability standards, testing & certification, and cyber-security. It further explores how Smart Grid affects disaster recovery operations for grid operators and the rebuilding efforts in the wake of Hurricane Irene and Superstorm Sandy in the northeastern United States.
The power distribution industry is an ever increasing industry with a diverse array of equipment types and user environments. This presentation discusses the differences between the various types as well as recent advancements in the industry including relay protection, operator safety, maintainability, integrated controls and arc flash mitigation. The equipment types discussed include: medium voltage & low voltage metal-clad and metal enclosed switchgear, switchboards, power distribution centers, and skid mounted substations. The discussion on relay protection provides an overview of the advantages of different protection schemes including the use of solid state and microprocessor based multifunction relays. Operator Safety includes the use of remote racking devices, remote control panels, arc flash mitigation, as well as a discussion on the emerging need for integrated controls within. Maintainability concentrates on the differences between the types of equipment to determine the best fit for the end-user environment. Additional topics include Main Tie Main Auto Transfer schemes, paralleling switchgear and applicable codes and standards.
Power Factor Correction (Capacitive) systems on LV and MV systems have both economic and technical feasibility in today’s power systems. An overview of power factor, active/reactive/apparent power, is presented. Other topics include sizing of capacitor systems to achieve PF goals for maximum payback and system features. With the increased use of modern computer systems and power electronic drives, power quality and harmonic distortion have become real challenges for the grid. Harmonic filter designs and features will be discussed as well as an overview of different types of harmonic distortion.
As the Grid evolves, some are wondering what the role of GIS will be. GIS will define and maintain more accurate, complete network models and be an integral part of new Outage Management (OMS) and Advanced Distribution Management Systems (ADMS). GIS will provide the geographical organizational aspects of Business Intelligence (BI) and Data Analytics (DA) capabilities. Whether it is analysis of networks or display of Key Performance Indicators, the results will come from time-series simulations that much more nearly model real time network performance.
A strong and growing desire exists, throughout society, to consume electricity from clean and renewable energy sources, such as solar, wind, biomass, geothermal, and others. Due to the intermittent and variable nature of electricity from these sources, our current electricity grid is incapable of collecting, transmitting, and distributing this energy effectively. The "Smart Grid" is a term which has come to represent this 'next generation' grid, capable of delivering, not only environmental benefits, but also key economic, reliability and energy security benefits as well. Due to the high complexity of the electricity grid, a principle based System Architecture framework is presented as a tool for analyzing, defining, and outlining potential pathways for infrastructure transformation. Through applying this framework to the Smart Grid, beneficiaries and stakeholders are identified, upstream and downstream influences on design are analyzed, and a succinct outline of benefits and functions is produced.
We expect more and more from our electrical power systems even as we push them into longer and greater use than ever anticipated. We continue to put new demands on these systems – harmonic loads, distributed interconnections, contingency overloads, etc. Gone are the days of strictly central generation with dispatch uni-directionally toward loads centers. Historically, electrical power systems and their components were overbuilt, but today they are built to exacting standards based upon lowest first cost. As such, maintenance of old and new equipment alike is critical to their safe and reliable operation. Society has come to demand perfect power reliability, and worker safety has become paramount. An overview of some of the testing methods required to maintain electrical power equipment will be presented.
As this seminar answers the question “What does ‘Purging + Pressurization’ mean?”, we discuss the following topics: Primer on hazardous locations, Explosive environments, Classified areas; Methods of protection for electrical equipment & systems; North American and International standards; Types X, Y and Z purge systems for Class I gaseous locations & pressurization systems for Class II dust locations; Comparison of purge + pressurizing systems to “other” methods of protection (e.g. explosion proof, intrinsic safety, etc.); Leakage compensation vs. continuous flow purge systems, including major features & benefits; Applications in oil, gas, pharmaceutical, biotech industries and more; Pressurized Enclosures, motor purge systems and complete room pressurization systems.
Small modular reactors (SMRs) are defined as having electrical outputs of 300 MW or less. They have the advantage of requiring less capital outlay for a utility relative to the large nuclear power plants that are now being constructed. Furthermore, they are more in line with the grid in smaller markets. These advantages are discussed in this presentation along with how the vendors deal with the cost per kWh and safety issues. Examples of several designs called integrated pressurized water reactors are explained. The related activities of the Department of Energy, the Nuclear Regulatory Commission and interested electric utilities are also provided.
This course will discuss the basics of
designing and specifying power and control systems in pre-engineered
buildings. Major topics are:
Distributed power architectures replace multiple central power sources with a single bulk supply that is converted to the end-use voltages by DC/DC converters located at the point of need. Distributed power networks let engineers power all the subsystems from a single 28-volt bus and a central battery bank rather than running redundant wiring for each voltage level throughout the airframe. This presentation discusses the following topics: Assembly Layout, Reliability, Vibration & Thermal Management, Noise & Transients, Usage, Circuit Protection and Voltage Quality.
Several aspects of recycling facilities and how these complement the waste-to-energy process are explored. Topics include solid waste hierarchy, how waste is managed on Long Island, how recycling works, how recycling saves energy, and where recycling is going. I addition, an overview of the waste-to-energy industry is presented, how waste-to-energy works, a review the technology and details of it in LI.
The reduction of shipboard airborne emissions has been receiving increased attention due to the desire to improve air quality and reduce the generation of greenhouse gases. The use of a fuel cell could represent an environmentally friendly way for a ship to generate in-port electrical power that would eliminate the need to operate diesel-driven generators or use shore power. This presentation includes a brief explanation of fuel-cell theory, as well as a description of the various types of fuel cells in use today, together with advantages and disadvantages of each type. A review of the history of fuel cells in marine applications is also included. In addition, the presentation includes the results of a study conducted using computational fluid dynamics (CFD) to both optimize the configuration of a solid-oxide fuel cell and develop adjustment factors that permit single-cell CFD results to be modified to estimate the performance of stacks containing multiple fuel cells.
A distributed control system (DCS) refers to a control system of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each component sub-system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring. DCS is a very broad term used in a variety of industries, to monitor and control distributed equipment in industrial process and power plants. While instrumentation and control (I&C) systems comprise a very small fraction of a plant’s total costs, the impact on overall operations and asset management can be significant. Reaching and maintaining higher levels of plant availability, reliability and performance are today’s business drivers. This talk provides an overview of modern Distributed or Plant Control Systems (DCS/PCS) with a focus on specific features.

In 2003, a widespread blackout affected 50 million people in eight U.S. states and two Canadian provinces. The following year, the U.S. Department of Energy, Office of Electric Transmission and Distribution, formed a group of stakeholders in the electric industry to design "GRID 2030." The aim of this workshop was to develop a road map that represented the critical GRID architecture, accelerate technology acceptance, strengthen the electrical market, and develop private/public partnerships. This lecture also discusses the collaboration of private and public organizations, including those integrating renewable energies with commercial-off-the-shelf technologies.
Strategies are covered to minimize the carbon footprint in fuel production by maximizing carbon conversion from biomass.
This lecture covers efficient automation of the power distribution system, and reviewes a case study of electric power distribution systems. Alternative system designs are also reviewed.
Existing LI wind-power projects and plans for future projects, such as the one off the coast of Jones beech, are discussed. Site screening, avian avoidance, grid interconnections and numerous other installation considerations are explained. Also covered are the environmental benefits, aesthetics and costs.
The next great economic era will be powered by hydrogen pointed out Mr. Rifkin, the president of the Foundation on Economic Trends. Drawing on a variety of well-balanced research studies, his basic premise is that the world must switch from a fossil-fuel economy to a hydrogen economy. This must happen soon for three reasons: the imminent peak of global oil production, the increased concentration of remaining oil reserves in the Middle East one of the most politically and socially unstable regions of the world and the steady heating up of the world's atmosphere from fossil-fuel dependency. The Center for Fuel Cell Development at the Institute for Research and Technology Transfer (IRTT) of Farmingdale State University of New York has successfully developed new metal treated bipolar plates for PEM fuel cell power stacks. These power stacks are much safer, very robust and more economical than the graphite bipolar plates that are currently being developed nationwide. The metal bipolar plates provide at least a 12% savings in hydrogen consumption in comparison to graphite because of the lower ohmic resistance of metal.
Today, 21% of energy use is in lighting, and, perhaps, half of this energy or more can be saved by switching to efficient and cold solid-state lighting sources. Solid-state lighting will use visible and UV LEDs that are projected to reach lifetimes exceeding 100,000 hours. From traffic lights to road signs, from automobile taillights to outdoor displays, from landscape to accent lights, solid-state light sources have already arrived as harbingers of the next lighting revolution. However, the creation of appropriate sources of white light is the ultimate goal of the solid-state lighting technology. The efficiency of white LEDs using conversion of blue or UV light in ionic phosphors (now approximately up to 20 lm/W, already twice of that for incandescent lamps) is expected to reach 50 lm/W by year 2010. Polychromatic all-semiconductor lamps based on state-of-the-art red-to-yellow AlGaInP LEDs and blue-green AlInGaN LEDs with the quantum efficiencies in excess of 50% and 20%, respectively, can exhibit luminous efficiencies exceeding 100 lm/W and compete with any conventional white lamp. Optimization of such multi color LED modules is one of the most important problems of the emerging solid-state lighting technology. A dichromatic LED lamp can only provide a high efficacy with general Color Rendering Index close to zero. Trichromatic and quadrichromatic lamps are able to cover the entire range of reasonable general CRI values. |
