Abstract

The invention relates to a distributed power generation system with circuit protection. The system comprises a photovoltaic array, an inverter and a power grid, wherein the inverter comprises a digital signal processor (DSP) controller. Safe and high-efficiency grid connection of the inverter can be achieved by a protection circuit in the DSP controller, the randomness and the indirectness of electric energy generated by a weapon on the power generation system are timely controlled, impact damage to the power grid is prevented, and the protection function of the circuit is achieved.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a distributed power generation system with circuit protection. Background technique [0002] Under the general trend of global energy saving, environmental protection and sustainable development, distributed power generation devices such as wind power generation and photovoltaic power generation have gradually become an effective way to meet the demand of load growth, reduce environmental pollution, improve comprehensive energy utilization efficiency and power supply reliability. Distributed power generation refers to a system that arranges power systems near users in a small-scale and decentralized manner, and can independently output electric energy. Since the large power grid system cannot flexibly track load changes, local accidents are easy to expand and cause large-scale power outages. Using distributed grid-connected power generation can effectively solve this ...
