Abstract

The invention discloses an expert system based transformer electromagnetic optimization design method and relates to an electrical data processing method of computer aided designs. The method comprises the following steps of: establishing an expert system of a transformer electromagnetic optimization design; determining a target function and an optimization variable of the transformer electromagnetic optimization design and establishing constituent parts of the expert system. The expert system of the transformer electromagnetic optimization design is used in a manner that a lot of expert knowledge and experience are applied to transformer electromagnetic optimization design work. According to the expert system based transformer electromagnetic optimization design method disclosed by the invention, many defects that mathematical algorithms are relatively complex, non-professional people are not easy to master, the randomness is big and local optimum is likely to occur in prior art because a mathematical algorithm based solution is introduced into the transformer electromagnetic optimization design field are overcome.

Description

technical field [0001] The technical solution of the invention relates to a computer-aided design electrical data processing method, specifically an expert system-based electromagnetic optimization design method for a transformer. Background technique [0002] In the power system, the transformer is responsible for the task of power conversion between the same frequency and different voltage levels, and is one of the most important power equipment in the power system. In recent years, with the acceleration of power grid construction, the power generation and power consumption are increasing day by day. At the same time, the demand for transformers is also increasing, and the transformer manufacturing industry is developing rapidly. With the increase of transformer manufacturing raw materials and the improvement of national energy saving and consumption reduction requirements, designers pay more and more attention to how to shorten the transformer electromagnetic design cycle...
