Coupling of environmentally-induced discharge transients into space power distribution systems

The mechanism of space-plasma-induced discharge and its coupling with a large space power system are discussed. Data from both ground and flight experiments are reviewed to obtain an expected basis for the interactions. These concepts were applied to the space station solar arrays and distribution system. The effect of discharges was found to be a function of the discharge site. For most sites in the array, discharges would not seriously impact performance. A location at the negative end of the array where discharges could couple to the charge stored in system capacitors was identified. This latter case could impact performance
