Title: RF Power and HOM Coupler Tutorial

Abstract

Radio frequency (RF) couplers are used on superconducting cavities to deliver RF power for creating accelerating fields and to remove unwanted higher-order mode power for reducing emittance growth and cryogenic load. RF couplers in superconducting applications present a number of interdisciplinary design challenges that need to be addressed, since poor performance in these devices can profoundly impact accelerator operations and the overall success of a major facility. This paper will focus on critical design issues for fundamental and higher order mode (HOM) power couplers, highlight a sampling of reliability-related problems observed in couplers, and discuss some design strategies for improving performance.

  • Neural network computational models offer significant promise for improving several aspects of power plant operation. This paper provides a brief but comprehensive review of neural networks. Various learning paradigms are discussed, as is the use of neural networks for solving optimization problems. Several applications relevant to the utility industry are described briefly. These include load forecasting, security monitoring, turbine backpressure optimization and process modeling. These are applications in which the ability of neural networks to learn complex mappings from training data is used to develop estimators or predictors of various properties of interest. Characteristics that a problem should possess formore » a neural network approach to be viable are also discussed.« less
  • This paper is intended as a tutorial overview of neural network applications that are relevant to industrial and commercial power systems. The paper is arranged to provide the practicing engineer with answers to the following questions: (1) why would a neural network be needed; (2) what is required to use a neural network; (3) how are neural networks superior to conventional methods; and (4) what type of results are produced by neural networks? Introductory knowledge needed for understanding the application of artificial neural networks is provided and numerous example applications are referenced. The paper is purposefully written without state-of-the-art terminologymore » for the benefit of practicing engineers in facilities today who may not be familiar with neural networks. This paper is expected to be the first in a series that will provide a similar presentation of expert and fuzzy logic systems.« less
  • As wind energy becomes a larger portion of the world's energy portfolio and wind turbines become larger and more expensive, wind turbine control systems play an ever more prominent role in the design and deployment of wind turbines. The goals of traditional wind turbine control systems are maximizing energy production while protecting the wind turbine components. As more wind generation is installed there is an increasing interest in wind turbines actively controlling their power output in order to meet power setpoints and to participate in frequency regulation for the utility grid. This capability will be beneficial for grid operators, asmore » it seems possible that wind turbines can be more effective at providing some of these services than traditional power plants. Furthermore, establishing an ancillary market for such regulation can be beneficial for wind plant owner/operators and manufacturers that provide such services. In this tutorial paper we provide an overview of basic wind turbine control systems and highlight recent industry trends and research in wind turbine control systems for grid integration and frequency stability.« less
  • A neural network is a data processing system consisting of a number of simple, highly interconnected processing elements in an architecture inspired by the structure of the cerebral cortex portion of the brain. Hence, neural networks are often capable of doing things which humans or animals do well but which conventional computers often do poorly. Neural networks have emerged in the past few years as an area of unusual opportunity for research, development and application to a variety of real world problems. Indeed, neural networks exhibit characteristics and capabilities not provided by any other technology. Examples include reading Japanese Kanjimore » characters and human handwriting, reading a typewritten manuscript aloud, compensating for alignment errors in robots, interpreting very noise'' signals (e.g. electroencephalograms), modeling complex systems that cannot be modelled mathematically, and predicting whether proposed loans will be good or fail. This paper presents a brief tutorial on neural networks and describes research on the potential applications to nuclear power plants.« less
