Study on Optimization of Small-Scale and Simplified Models for Air-Core Reactors

Some large-sized electrical equipment of the power system has been approximately simulated by the equivalent small-scale model. And the method has great practical value in the power system simulation and scientific study. However, the common small-scale model of reactors can't simulate the EMI (Electromagnetic Interference) for other electrical equipment just because of only taking electrical parameters such as its impedance into consideration. In this paper, the simplified model is made to simulate the PFMF (Power-frequency Magnetic Fields) around air-core reactors. The model provides theories and technologies for the forecast of PFMF around air-core reactors. Besides, the optimal structures of bicyclic and tricyclic simplified models are made by analyzing small-scale experiments and simplified models. And the annlytical result is verified by making models in the laboratory.
