EDD

• EDD is a consulting and software development firm that provides model-based design and analysis services for large scale, critical, inter-dependent infrastructures.
• EDD has more than 10 years of industry experience improving operational performance, planning future requirements, and implementing next generation designs.
• EDD provides software development, training, and support for the Distributed Engineering Workstation (DEW).
• EDD has provided DEW solutions for Electrical Power Utilities, the U.S. Army, the U.S. Navy, EPRI, as well as various national laboratories, colleges, and universities.

DEW

• DEW is a multidiscipline, open-architecture environment, where new applications can be developed quickly and cost-effectively.
• DEW uses a single-model approach to support real-time analysis, system reconfiguration, operational planning and design updates.
• DEW solves systems that contain millions of nodes and can simulate cascading failures.
• DEW records SCADA measurements and system events, enabling historical restoration and analyses.
• DEW introduces a new paradigm for rapid analysis of large, reconfigurable systems through its use of Graph Trace and Generic Analyses.

More about Generic Analysis and GTA

Generic Analysis is an extension of Graph Trace Analysis (GTA), which was originally developed by EDD in the early 1990's, for integrated design and supervisory control of reconfigurable power systems. Benefits of the EDD/GTA approach include:

• Using a shared model that graphically corresponds to an engineering schematic or isometric diagram for all analyses and operational functions;
• Derives functional, spatial, and temporal relationships directly from the shared model;
• Performs design and control analyses consistently with needs of engineering design, operations, and planning groups;
• Collaboratively structures steady-state, discrete event, and transient analysis across multiple system types;
• Eliminates the need for manipulating large matrices;
• Simplifies data and analysis integration for multi-domain problems, as all data relates to shared model;
• Reduces data collection and storage requirements;
• Executes analysis fast enough to support real-time supervisory control of systems with millions of nodes and thousands of switching devices;
• Naturally compatible with distributed processing techiques.
