Description

technical field

[0001] The invention relates to the field of wind power generation, in particular to a wind farm electrical system with a simple structure that adopts a switched reluctance generator that directly outputs direct current electric energy as a wind power generator, full direct current electric energy convergence and direct current transmission. Background technique

[0002] With the large-scale development of one-time petrochemical resources such as oil and coal, the energy crisis and environmental degradation have become increasingly serious. The only way to solve this problem is to accelerate the development of sustainable resources. Among the existing renewable energy, wind energy is one of the highest resources regardless of scale or availability, and wind energy does not consume mineral resources in the process of utilization, and does not emit harmful substances. It is regarded as clean, green and environmentally friendly. of energy.
