Abstract
Solar photovoltaic power generation is an important mode of solar developing and utilization. Existing solar power generation mainly comprises an off-grid type power generation system and an in-grid power generation system, and relevant technologies are mature. A photovoltaic power generation system lead a solar battery board to form integration through a series mode and a parallel mode to form a direct current power supply, and then, direct current power is converted into alternating current power or other types of power through a power electronic device. In order to improve the integral efficiency of the solar power generation system, solar battery array voltage is high, and as increasing of power of the solar power generation system, system circuit networks are more complex. In view of actual demands of the solar power generation system, the utility model provides a design method of a novel photovoltaic power generation system bus box, the novel photovoltaic power generation system bus box achieves basic the function of connecting a plurality of solar battery arrays in parallel and outputting, each branch circuit is independently controlled, and two-level relay control is adopted, thereby guaranteeing personal safety of operators. Each branch circuit is provided with an anti-reverse connection device, a lightening protection device and a voltage and current detection device, thereby being convenient for on-site construction and subsequent maintenance.
