e-Battery for Energy Storage Systems

This paper presents the concept of electronic battery (c-Battery) for energy storage systems. The proposed c-Battery is a combination of ultra capacitor bank and power electronic converters. This paper looks at issues related to chemical batteries and proposes the concept of an e-Battery. The proposed e-Battery overcomes many of the drawbacks of a conventional chemical battery. The control strategy developed for the closed loop operation of the proposed e-Battery is also presented in this paper. The performance of the proposed e-Battery is verified through detailed time domain simulation in PSCAD/EMTDC. A hardware prototype is built to validate the performance of the proposed e-Battery experimentally

Interactive Simulation And Analysis Of Emission Reduction Systems In Commercial Boilers

In this paper we describe an interactive virtual environment developed to model an emission reduction system for commercial boilers. The interactive environment is used to optimize the performance of the reduction system through the spatial adjustment and spray reconfiguration of reagent injectors. We describe the three principal components of the system: a computational model for the particle dynamics, a three-dimensional display device and graphics environment, and the communication layer that allows the interaction of the user in the visualization environment with the computational model. Timing results for each component are given for three hardware configurations that demonstrate the real-time performance of this tool. INTRODUCTION The advent of distributed memory computing has enabled the rapid solution of increasingly complex numerical models for a wide variety of three-dimensional applications. Interactive visualization tools that allow scientists to effectively validate and ..

Interactive Computational Models of Particle Dynamics Using Virtual Reality

We discuss an interactive environment for the visualization, analysis, and modification of computational models used in industrial settings. In particular, we focus on interactively placing massless, massed, and evaporating particulate matter in computational fluid dynamics applications. We discuss the numerical model used to compute the particle pathlines in the fluid flow for display and analysis. We briefly describe the toolkits developed for vector and scalar field visualization, interactive particulate source placement, and a threedimensional GUI interface. This system is currently used in two industrial applications, and we present our tools in the context of these applications. We summarize the current state of the project and offer directions for future research.
