A satellite ground power supply and distribution test equipment generalization design method relates to the satellite ground power supply and distribution test equipment design field. A largest envelope which makes that equipment resource configuration reaches demands of all the researched-satellite-to-ground power supply and distribution test equipment is included. Enough redundant backups and extensible resources are reserved and a construction rule of various kinds of resources in the equipment is made. Aiming at different requirements of different satellites to a cell on-off interface circuit and the like, a driving power supply in the power supply and distribution test equipment and a passive contact point of an electromagnetic relay are simultaneously led out to an equipment output interface, and each satellite can complete control mode conversion through a special design of a cable plug according to a detailed design of a satellite power supply controller. The test equipment can be applied to a subsequent satellite without any reconstruction. Material resource cost is greatly reduced and rapid interchange of the test equipment among the different satellites is realized. Simultaneously, a processing unit can realize production line type development and a development period of the equipment is greatly shortened.
