Title:
HIGH-VOLTAGE PHOTOVOLTAIC POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/232691
Kind Code:
A1
Abstract:
Disclosed is a high-voltage photovoltaic power generation system, belonging to the technical field of photovoltaic power generation. A plurality of photovoltaic assemblies are connected in series to form photovoltaic subgroup strings, each photovoltaic subgroup string is connected to an electrical isolation controller, and all the electrical isolation controllers are connected in series and are then connected to a photovoltaic inverter; and the electrical isolation controller comprises a maximum power point tracking module and an electrical isolation module, and the maximum power point tracking module is connected to the electrical isolation module. According to the present invention, a higher direct-current voltage level can be realized under the condition that the voltage-withstand level of a photovoltaic assembly is not improved, and at the same time, the series mismatching risk caused by long strings is avoided, the system cost is remarkably reduced, while the efficiency of the photovoltaic system is improved, and a good use prospect is achieved.
