Photovoltaic power generation system and photovoltaic power generation system control method

摘要

A photovoltaic power generation system, wherein electrical power generated by multiple photovoltaic power generator units is gathered in a single unit group power collection control section and, in addition, supplied (transferred) to a single power converter corresponding to a single unit group power collection control section. The photovoltaic power generation system comprises generator unit groups formed by arrangement of multiple photovoltaic power generator units and unit group power collection control sections, which are connected with the photovoltaic power generator units through unit cables, and collect and control the electric power generated by the photovoltaic power generator units.

主权项

1. A photovoltaic power generation system control method comprising forming generator unit groups by arranging a plurality of photovoltaic power generator units having solar cell modules and a tracking drive section imparting tracking drive to the solar cell modules, controlling the tracking driver section via a unit group power collection control section collecting the electrical power generated by the generator unit groups, and effecting the power conversion of the generated electrical power collected by the unit group power collection control sections using power converters,
the method comprising: identifying a photovoltaic power generator unit exhibiting power generation malfunction based on a power generation state of each photovoltaic power generator unit and correcting the power generation malfunction of the identified photovoltaic power generator unit via the unit group power collection control section.
