PHOTOVOLTAIC GENERATION SYSTEM USING PARALLEL INVERTER CONNECTED GRID

摘要

PURPOSE: A solar power system using a parallel inverter connected to a system is provided to prevent harmonic distortion by reducing the deterioration of photovoltaic modules due to stray current. CONSTITUTION: A photovoltaic module converts solar energy into DC electrical energy. Inverters(412,422) convert the DC electrical energy into AC electrical energy. LC filters(413,423) remove noise included in the AC electrical energy. Capacitor groups(414,424) are connected between a reactor of the LC filter and the other part of the photovoltaic module. The capacitor group lowers stray current.
