Novel multifunctional fault current limiting system based on optical storage technology and control method thereof

technical field [0001] The invention belongs to the technical field of electric power and new energy, and relates to a novel multifunctional fault current limiting system based on optical storage technology and a control method thereof. Background technique [0002] With the continuous development of the modern power system and the continuous expansion of the system scale, the short-circuit capacity of the system increases, resulting in an increase in the short-circuit current in the event of a fault, and the requirements for the capacity of the primary equipment are getting higher and higher. However, the primary side equipment manufacturing technology has not achieved gratifying results, causing the contradiction between the two to become increasingly prominent. At the same time, with the continuous connection of various nonlinear, shock and unbalanced loads to the power grid, the current and voltage waveforms of the power grid are distorted, resulting in voltage quality p...
