| description | The invention provides an inverter I-GBT redundancy design and control method and system for an unattended photovoltaic power station. The method comprises the following steps: step 1, calculating the number of I-GBT redundancy required by an inverter of a target photovoltaic power station; step 2, the obtained redundant IGBTs are distributed to a DC-DC conversion module and a DC-AC conversion module in the inverter; step 3, the DC-DC conversion module and the DC-AC conversion module which are distributed with the redundant IGBTs are controlled; according to the invention, the redundant IGBT can be used for standby at any time for replacement, the equipment reliability is improved, the power generation loss caused by poor accessibility after a fault can be reduced, the reliability of an unattended photovoltaic power station inverter in the prior art is further improved, the fault rate is reduced, and the power generation amount is improved.
