Description

technical field [0001] The invention relates to a superconducting energy pipeline applied in the field of energy Internet. Background technique [0002] The distribution of resources and users in our country does not match, and both fuel and electric energy need to be transmitted over long distances. With the large-scale development and utilization of renewable energy, this mismatch is further exacerbated, and the national interconnected power grid will play a more important role in the new generation of power systems. important role. By adopting a more flexible and optimized operation mode, the cross-regional interconnection grid can achieve a dynamic balance between power supply and demand across the country, which will effectively promote the consumption and utilization of a high proportion of new energy. Although UHV transmission technology has great advantages over traditional high-voltage transmission methods in terms of large capacity and long-distance transmission, ...
