Embodiment Construction

[0022] Taking the mesh parabolic antenna carried by a certain type of satellite as an example, the mesh parabolic antenna carried by the satellite will block the solar cell array after being deployed in orbit. Based on the shading effect caused by the three parts of the suspension wire, the shading conditions of the antenna on the satellite solar wing are divided into three types: the truss strut shading condition, the mesh paraboloid shading condition, and the suspension wire shading condition.

[0023] According to the determined 3 kinds of solar wing shading conditions, the shading test under the ground natural light conditions is carried out, and the truss poles, mesh paraboloids, and suspension wires of the satellite antenna are respectively simulated at different distances and at different angles to the solar cell circuit. Under the shading state of the satellite solar wing, the loss of the output characteristics of the solar cell circuit relative to the unshading state u...

Abstract

The invention discloses a satellite solar wing occlusion testing method, comprising: determining, by an analysis, a test power curve after output power loss under a working condition that a variety of solar wings are occluded, storing an occlusion curve in the form of discrete points into a solar cell simulator, and completing solar wing occlusion testing project in combination with a matching ground testing device. The invention is suitable for a current situation that the structure of the satellite is complex and a large expandable antenna is applied to the satellite, makes compensation for satellite power system testing in the working condition of solar wing occlusion, enhances the comprehensiveness of the satellite power system testing, and thus has great application and promotion value.

Description

technical field [0001] The invention relates to a test method for satellite solar wing shading, which is suitable for obtaining the performance index of the satellite power supply system under the working condition of solar wing shading during the test process of the satellite power supply system, and belongs to the field of satellite testing. Background technique [0002] With the development of satellite payload technology, the aperture of the antenna on the satellite is getting larger and larger. With the rotation of the solar wing and the change of the sun angle, at certain moments, the antenna will block the solar wing, and celestial bodies will sometimes block the solar wing during the operation of the satellite. of occlusion. Shading reduces the intensity of sunlight projected on the surface of some cells, leading to a decrease in the output current of the entire solar cell array and attenuation of the output power of the solar cell array, which is a test of the stab...
