“…For example, to improve the efficiency of a generator, the numerical simulation and the response surface methodology (RSM) are combined to optimize the stator slot structure of the alternator [14]; the CFD and the genetic algorithm are adopted to optimize the mutual configuration of the winding and cooling channel, resulting in dramatic decrease in the hot spot temperature of the dry-type transformer [15]; the temperature distribution is obtained based on the design parameters of the dry-type reactor, and the amount of metal conductors in the coil is optimized by particle swarm optimization, thus verifying the correctness of the optimization method [16]. In addition, the orthogonal test method is also applied in combination with numerical simulation to optimize the structure of dry-type air core reactors [17,18].…”

In this paper, the CFD (computational fluid dynamics) model is established for the low voltage winding region of an oil-immersed transformer according to the design parameters, and the detailed temperature distribution within the region is obtained by numerical simulation. On this basis, the RSM (response surface methodology) is adopted to optimize the structure parameters with the purpose of minimizing the hot spot temperature. After a sequence of designed experiments, the second-order polynomial response surface and the SVM (support vector machine) response surface are established respectively. The analysis of their errors shows that the SVM response surface can be better used to fit the approximation. Finally, the PSO (particle swarm optimization) algorithm is employed to get the optimal structure parameters of the winding based on the SVM response surface. The results show that the optimization method can significantly reduce the hot spot temperature of the winding, which provides a guiding direction for the optimal design of the winding structure of transformers.

“…Orthogonal experimental design is a scientific method to study and deal with multifactor experiments. Its main advantage is that it can select a few representative experimental schemes from many experimental schemes and infer the optimal scheme by analyzing the results of these experimental schemes (Yuan et al , 2021). Based on the design results of the ACT’s windings structure in Section 3, the orthogonal experiment method is used to conduct the magnetic shielding design.…”

Purpose The purpose of this paper is to study the multi-objective optimization design method of high-power high-frequency magnetic-resonance air-core transformer (ACT). Design/methodology/approach First, this paper studies the interleaved winding technology, the process of modeling and simulation, the calculation method of high-frequency loss of Litz wire and the design of magnetic shielding in detail. Second, the multi-objective optimization design process of high-frequency magnetic-resonance ACT is established by parametric scanning method and orthogonal experiment method. Findings An ACT model of 2 kV/100 kW/81.34 kHz was designed. The efficiency, weight power density and volume power density are 99.61%, 21.6 kW/kg and 5.1 kW/kg, respectively. Finally, the multi-physical field coupling simulation method is used to calculate the port excitation voltages and currents and temperature field of ACT. The maximum temperature of the ACT is 95.5 °C, which meets the design requirements. Originality/value The above research provides guidance and basis for the optimization design of high-power high-frequency magnetic-resonance ACT.

Bridge arm reactor is widely used in voltage sourced converter based HVDC transmission projects, whose temperature distribution is the critical factor determining its operating life. However, the prevailing methods cannot effectively address the pending problem of excessive hot‐spot temperature. In this paper, a radial layered structure is proposed, and each encapsulation is layered according to the ‘Huke curve’, reducing the overall temperature rise and metal consumption of the reactor significantly. Further, a combined‐constraints‐based optimization (CCBO) methodology is proposed with combined advantages of the isothermal rise method and the equal resistance voltage method. A joint solution model for the electrothermal parameters of multiple encapsulations is established. The optimal parameters combination is obtained through iterations, and the temperature rise distribution tends to be balanced. The calculation example for an 800‐kV bridge arm reactor with the radial layered structure shows that the hot spot temperature rise is 33.9% lower than that of the traditional structure, and the metal consumption decreases by 61.5%. Through the CCBO methodology, the temperature difference among encapsulations reduces by 12.5% in comparison with the isothermal rise method. From this work, encapsulations’ temperature rise distribution and their metal consumption become balanced and less, which will improve the reactors’ operation reliability.
