The Space Lab is in the Low Earth Orbit (LEO), in which space environment is complex and varied. The plasma effect of the High Voltage Solar Array (HVSA) is outstanding in the environment. In order to adopt the HVSA, the plasma effect and protection are the key technical challenges. The LEO plasma environment is analyzed, and the mechanism and effect of the arcing discharge for the HVSA are studied. The test for simulating the LEO plasma environment is carried out, which validates the adaptability of semi-rigidity solar array and flexible solar array in the space environment.
