IEEE Columbus Power & Energy Society January 19th Program

Date:   Thursday, Jan. 19th, 2017                       Refreshments:  5:30 to 6:00 PM

Presentation:  6:00 to 7:00 PM                         Earn 1.0 CPD Hours

Location:  AEP Ohio Office, Conference Room 2G, 700 Morrison Road, Gahanna, Ohio 43230

Title:  “More Accurate and Optimized Substation Grounding Study Methodologies”

Abstract:  This seminar will introduce hands-on solid modeling experience of the safe, optimal ground grid design for a large Extra High Voltage (EHV) substation.  The optimized ground grid meets the IEEE-80 standards for safety without compromising on step or touch potential thresholds.  The ground grid has been designed in CDEGS software using fault current flow concepts, with multiple injection points simulating the actual conditions and fault currents at the substation.  In addition, the new clearing time analysis and grounding study safety assessment strategy are implemented.  The method focuses on substation specific data to perform substation grounding studies and does not assume the fault current split factors, or utilize the IEEE-80 curves. The method is conceptually correct, meets safety requirements, and leads to copper savings. Thus, a safe and cost-optimized ground grid for an EHV station is achievable.

AP-MTT Mtg (Dec 5)

Columbus IEEE AP-MTT Chapter Presents: 

 apmtt.png Solution of Extremely Large Forward and Inverse Problems

in Computational Electromagnetics: BIG DATA Aspects

 

Prof. Levent Gürel, IEEE Distinguished Lecturer

ABAKUS Computing Technologies, Adjunct Professor, ECE, UIUC

Date: 12:00 – 01:00 PM, Monday, December 5th, 2016 

Place:  ElectroScience Lab, The Ohio State University, MRC Conference Room #132, 1330 Kinnear Road, Columbus, OH 43212

Abstract: As we solve some of the largest problems in the interdisciplinary domain of computational electromagnetics, we have to deal with various aspects of big-data issues routinely. Most recently, we have achieved the solutions of larger than 1,500,000,000×1,500,000,000 (1.5 billion!) dense matrix equations! This achievement is an outcome of a multidisciplinary effort involving physical understanding of electromagnetics problems, novel parallelization strategies (computer science), constructing parallel clusters (computer architecture), advanced mathematical methods for integral equations, fast solvers, iterative methods, preconditioners, linear algebra, and big data. Solving such large problems on a regular basis requires the generation, representation, storage, processing, analysis, transfer and communication, visualization and interpretation of extremely large data sets in the order of multiple terabytes. Accurate formulations of real-life electromagnetics problems with integral equations necessitate the solution of extremely large dense matrix equations. Solutions of such tremendously challenging problems cannot be achieved easily, even when using the most powerful computers with state-of-the-art petascale computing capabilities. Instead, we have been solving some of the world’s largest integral-equation problems in computational electromagnetics by employing fast algorithms implemented on parallel computers. To achieve optimal management of multiple large data sets, we design and implement the handling of data in various levels of cache, memory, and disk, leading to meticulously designed out-of-core (OoC) schemes. That way, we enable the solution of unprecedentedly large problems with limited amounts of DRAM. In order to avoid decelerating the solution, we optimize communications among CPU cores, among processors, among nodes, from CPU to disk (and back), and in the case of heterogeneous architectures, we carefully control the data traffic to/from GPUs. Furthermore, we employ MPI and OpenMP simultaneously in a parallelization strategy designed to reduce data duplications among processes so that vast numbers of cores can be efficiently utilized without requiring extra memory.

I will present fast and accurate solutions of large-scale electromagnetic forward and inverse problems involving three-dimensional geometries that are larger than 1000 wavelengths using the multilevel fast multipole algorithm (MLFMA) and parallel MLFMA. Solving the world’s largest computational electromagnetics problems has important implications in terms of obtaining the solutions of future grand-challenge problems in imaging, (subsurface), optics, nanotechnology, bioelectromagnetics, metamaterials, remote sensing, as well as plethora of other disciplines of science, e.g., acoustics, elastics, quantum mechanics, astrophysics, molecular dynamics, electro-statics, fluid dynamics, thermodynamics.
