Power Plant Design and Simulation

Design and Simulation represents two different areas, but they are connected through the same processes, i. e., an excellent understanding of system functions and integration.

A plant design modification means any change to a current design that will fix a problem or improve the function, or a change that creates a new product design.  Plant design occurs in three phases; 1) the conceptual phase is the "system analysis" phase where the theoretical designs and/or changes are created and the pros and cons of the design are established.  Feasibility studies and cost evaluations are also performed in this phase. The final products of the system analysis are the proposed new design(s) and/or design change(s), which have the best cost and benefit to the customer.  In some cases, a conceptual design has already been developed and the first phase is not required.  If the conceptual design is already developed, it is always wise to review the design for possible flaws and correct them before you proceed.; 2) the "detailed design" phase produces the final design product.  The conceptual design is developed into a final detailed design package. All facets of engineering are involved in the detailed design development.  The detailed design package includes design specifications, design drawings, design procedures, design requirements, quality assurance requirements, start-up specifications and requirements, and, if required, regulatory requirements; and 3) the "design implementation" phase takes detailed design package and provides an implementation plan which includes purchase of materials and/or equipment, start-up and/or retest requirements and procedures, and an implementation schedule which includes estimated construction costs and schedules.

The processes that may be used during a plant design evolution are:

Computer Simulations
Computer simulations include the simulation of processes such as fluid flow, equipment performance, structural performance, combustion, optimum process design, heating, ventilation, air conditioning, and heating (HVAC), control room, and fire/fire protection.

Power plant simulation requires the understanding of human, equipment, and system behavior.  The understanding of human behavior is necessary to ensure that correct and timely actions are model correctly.  The understanding of equipment behavior is required to model the response of the equipment to other associated elements, i. e., the change in pump performance because of changes in pressure drop or electrical load.  The understanding of system behavior and system integration is required since a number of systems are usually interrelated and the performance change in one system will change the performances of other associated systems.  The understanding of all these elements will result in a successful simulation and design change, if necessary.  Typically, a simulation uses a computer software package that is compatible to the application being simulated.  For example, a steady-state fluid flow problem may be solved with a piping simulation program, such as KYPIPE, or a transient two-phase situation may be simulated with a more elaborate program, such as RELAP5, and a structural simulation may be accomplished with ANSYS or ALGOR software.  All these efforts have one thing in common; the user must be familiar with the software and know how to model the application.  EDA has the experience in developing detailed models of many different situations with validated computer programs, which will help the user solve his or her problem.  Other methods may be used, i.e., see calculations, to analyze certain aspects of the design.

Design Audits
Design audits consist on reviewing the procedures and processes for conducting design changes and design change implementation. Audits are conducted based on an audit plan, which has been devised by EDA and approved by the client.

Analysis Verification
Analysis verification may consist of several processes depending on the clientís needs.  Review of analysis procedures may be part of this review.  Typically, analysis verification is the review of previously performed analyses.  A detailed review of each detail of the analysis may be performed or a more general review may be performed which inspects the results and the input for consistency, accuracy and realism. Alternatively, a more rigorous independent verification may be conducted which uses a completely independent approach to arrive at the solution and a comparison of the results is made to ensure agreement.

Computer Support
EDA provides a wide range of computer support activities.  The computer aided design (CAD) groups provides all software and hardware support for designing structures and systems.   EDA provides expertise in designing web layouts and graphic design.  EDA can provide evaluation of your network layout and propose optimum enterprise solutions for your company.

Design Review
A full range of design review capabilities is provided by EDA.  A detailed comprehensive design can be provided by EDA or a design review can be provided according to customerís specification. In addition, quality assurance audits can be provided.

Project Management
Complete project management is provided by EDA.  Initial conceptual design and cost estimates, PERT charts and scheduling are provided.  EDA can provide individual project management as needed.  Project management training can also be provided.

Financial Review
Financial analyses are provided for all projects.  These analyses provide break even, cash flow and go or no go projections.

Quality Control and Assurance

EDA personnel have many years of successful experience in the areas of quality assurance and control.  The goal is to perform the work correctly the first time and this is ensured through the quality assurance process.  All calculations and design changes are performed with quality and timeliness in mind.  It is believed that quality work provides the less expensive approach to completing the project.  To accomplish this, the quality control and assurance must be managed properly and EDA provides this service as part of their standard engineering support services.
