<div class="htmlview paragraph">A family of Electrical Power System (EPS) analysis tools that is generic in nature have been developed to perform EPS analyses to evaluate the design and operation of a space vehicle from an electrical power perspective. The tools were developed by the Electrical Systems Analysis Task of McDonnell Douglas Space Systems Company, Houston Division (MDSSC-Houston) under the Applications and Analysis Support Contract (AASC) in support of the Systems Engineering Division/ET at NASA/Johnson Space Center (JSC) within the Engineering Directorate. To date the tools have been used to analyze the power systems on the Space Station Freedom (SSF), Orbital Maneuvering Vehicle (OMV), and Assured Crew Return Vehicle (ACRV), but are adaptable to any space vehicle.</div>
