Abstract

The design of Space Station Freedom´s electric power system (EPS) is reviewed, highlighting the key design goals of performance, low cost, reliability, and safety. The EPS design is divided into three separate areas: power generation and storage, power distribution, and power management and control. Both photovoltaic and solar dynamic power generation and storage systems are used. Tradeoff study results that illustrate the competing factors responsible for many of the more important design decisions are discussed. Reliability and maintainability, as well as verification and testing, are addressed.<>
