Method and system for constructing electromagnetic transient IGBT (Insulated Gate Bipolar Translator) real-time model

Abstract

The invention discloses an electromagnetic transient IGBT real-time model construction method and system, and relates to the technical field of low-frequency power transmission, and the method comprises the steps: obtaining the structure data and training data of a to-be-constructed IGBT, carrying out the data preprocessing of the training data, generating corresponding training feature data, carrying out the simplified solving of a preset gate pole switch delay model through the structure data, and obtaining a real-time model of the to-be-constructed IGBT. The method comprises the steps of obtaining a target gate pole switch delay model, training a preset electromagnetic transient model by adopting training feature data to generate a target electromagnetic transient model, and constructing an electromagnetic transient IGBT real-time model corresponding to an IGBT to be constructed by adopting the target gate pole switch delay model and the target electromagnetic transient model. The technical problem that an existing IGBT transient simulation model needs to consume a large number of computing resources and is not suitable for a real-time simulation scene, and consequently the practicability of the IGBT transient simulation model is low is solved.
