The invention relates to a high-coupling split reactor modeling method and device, computer equipment and a medium. The high-coupling split reactor modeling method comprises the following steps: establishing an ideal coupling reactor sub-model; determining a fourth-order admittance matrix of the high-coupling split reactor according to the frequency characteristic parameters of the four ports of the high-coupling split reactor in the preset frequency range; determining a fourth-order admittance matrix of the ideal coupling reactor sub-model; determining a fourth-order admittance matrix of thehigh-frequency module submodel according to the difference between the fourth-order admittance matrix of the high-coupling split reactor and the fourth-order admittance matrix of the ideal coupling reactor submodel; according to the fourth-order admittance matrix of the high-frequency module sub-model, adopting a four-port pi-shaped equivalent circuit, and obtaining the high-frequency module sub-model through image method fitting; and connecting the high-frequency module sub-model with the ideal coupling reactor sub-model in parallel to obtain a high-coupling split reactor model. The high-coupling split reactor modeling method provided by the invention is high in accuracy.
Description
technical field [0001] The present application relates to the technical field of power electronic circuit simulation, in particular to a modeling method, device, computer equipment and medium for a highly coupled split reactor. Background technique [0002] In recent years, with the rapid development of the power system, the short-circuit current level of the system has increased sharply, and the continuous increase of the short-circuit current level has caused serious consequences to the power grid and restricted the development of the power system. Therefore, effective measures must be taken to limit the short-circuit fault current. [0003] The fault current limiter based on high-coupling split reactor has the advantages of low loss in current sharing condition, strong current limiting capacity, and excellent economy, and has important applications in limiting short-circuit fault current in power systems. [0004] The core component of the fault current limiter based on ...
