A conceptual framework for computer-directed monitoring, assessment and control of spacecraft power system is presented. The five principal operating modes are defined. The basic structure is divided into the functions that will monitor and assess the power system, the functions that will control the power system and the functions that will diagnose the power system both before and after equipment failures. The basis for these functions is the extensive experience with monitoring, assessment and control of terrestrial power systems with energy management systems. All applications are computer-based. However, some manual intervention may be required for degraded operation. A statement of the function methodology, the expected computer requirements, the expected periodicites and the operating restrictions are provided. The difference between power management for spacecraft power systems and energy management for terrestrial power systems are compared for each major function. The initial software development status of a power management system (PMS) for spacecraft power systems is presented for each major subsystem.
