Method for determining sheltering of solar cell array during in-orbit running of satellite and application of method
2012
The invention relates to a method for determining the sheltering of a solar cell array during the in-orbit running of a satellite and the application of the method. The method comprises the following steps of: making researches on solar illumination angle annual average change rules of a satellite orbit and the conditions of change of solar elevation along with the latitude during the in-orbit running of the satellite, judging whether the solar cell array of the satellite is sheltered or not by star, combining the configuration characteristics of the satellite, calculating a sheltered area, and obtaining the change trends of the sheltered area within one orbit and a year, so that the problem of abnormal charging array current caused by the sheltering of the solar cell array during the in-orbit running of the satellite can be solved according to results, and the problem of the optimal design of a cell distribution mode for solar cells of the satellite is also solved. The configuration design rationality of a spacecraft such as the satellite adopting the solar cell array as a main energy supply is improved, the utilization efficiency of the solar cells is improved, and good effects are achieved. The application has the advantages of lowering the cost of the cells of the spacecraft, improving the effective power supply capability of the spacecraft, improving the performance of the spacecraft, and the like.
