CONVERTER TRANSFORMER ON-LOAD TAP-CHANGER SWITCHING TOPOLOGICAL STRUCTURE DESIGN METHOD

The present application relates to a converter transformer on-load tap-changer switching topological structure design method. The method comprises the following steps: designing an on-load tap-changer basic branch library; selecting a basic branch from the on-load tap-changer basic branch library to construct a topological structure of an on-load tap-changer; determining whether the topological structure satisfies a performance requirement according to the selected basic branch; if the performance requirement is satisfied, obtaining a final topological structure of the on-load tap-changer, and if the performance requirement is not satisfied, reselecting a basic branch to construct a new topological structure of the on-load tap-changer, and repeating the steps of the method. The present application, when designing an on-load tap-changer, provides a converter transformer on-load tap-changer switching topological structure design method which has a simple method, and is easy to evaluate and highly efficient, ove
