Description

technical field [0001] The invention relates to a method for graphene capacitor design and capacitor capacity control based on an intelligent algorithm. Background technique [0002] In the power system, the compensation method is commonly used to improve the power factor. Among the existing compensation methods, the "power capacitor plus composite switch, and the parallel connection of intelligent capacitors" have great advantages and are widely used. However, for places with low power consumption, due to limited space and large configuration capacity of a single unit, only roughly graded compensation ranging from 10 to 40kvar per level can be done. Due to the comprehensive consideration of existing compensation, research on thin film materials for power capacitors has become the focus of modern power grid operation and management. [0003] Due to its unique structure, strong mechanical properties and excellent conductivity, graphene nanosheets have a good development in t...
