Problems solved by technology
With the increase in the complexity of satellite technology, the requirements for the satellite power supply and distribution test system are also getting higher and higher. It is obviously very uneconomical to configure a specific power supply and distribution test system for each satellite. Although the current test system The internal printed boards have been interchangeable between systems, but the change of the satellite interface leads to the need to re-modify the test system before it can be applied to the power supply and distribution test of other types of satellites. The construction period of the test system is long and the transformation cost is also high.
[0003] The utility model "a satellite ground power supply and distribution test system" with the application number of 200720173870.4 discloses a satellite ground power supply and distribution test system developed by using PLC technology. Develop different PLC control programs according to different task requirements

Embodiment Construction
[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0014] The output characteristic of a single solar cell is a curve similar to a parabola, and its open circuit voltage is V when the sun shines vertically oc , the short-circuit current is I sc , the operating point voltage is V mp , the operating point current is I mp , the output power of the solar cells is maximum at the operating point. The design of the power supply and distribution test system takes into account the various conditions of the solar cell array and the sun's incident angle, and the various test curves of the satellites that the power supply and distribution test system actually needs to simulate are obtained through the following calculations. First of all, each solar cell array adopts the method of connecting m cells in series and n cells in parallel. When the sun shines vertically, the index of a single solar cell array ...
