Optimization of Structural Parameters for a New-Type Magnetic Integration Structure CRT Considering Loss and Cost

The optimization of structural parameters of controllable reactor of transformer type (CRT) is of great significance for improving its economic benefits. This paper takes the new-type magnetic integration structure CRT as the research object. Qualitative analysis is employed to explore the relationship between loss, cost and structural parameters of CRT. The optimization model of structural parameters is established with the objective of minimizing cost and loss. The genetic algorithm is used to optimize the structural parameters of CRT. Based on this, a new economic calculation method of CRT's structural parameters is proposed. The results show that the optimization of CRT's structural parameters aiming at minimizing cost and loss is essentially to optimize the cross-sectional area of iron core and the length of winding coil. A new method for calculating CRT's structural parameters based on genetic algorithm optimization has more reasonable calculation results. With the increase of CRT operating time, the proportion of CRT use costs caused by loss will gradually increase. The methods and conclusions used in this paper provide some theoretical guidance for the structural design and optimization of CRT.
