摘　　要：针对可分离变压器气隙和漏磁较大等特点,采用耦合电感理论分别建立无补偿、一次侧补偿及双侧补偿时的状态空间数学模型,同时在MATLAB/Simulink中也建立相应的仿真模型,分析了运行频率及绕组补偿对可分离变压器运行性能的影响。仿真结果验证了所建模型的正确性和有效性,表明了双侧补偿技术可以大大提高可分离变压器的电能传输能力。Aiming at the characteristics of detachable transformer, such as large air gap and flux leakage, this paper, adopting coupling inductance theory, establishes separately mathematical models of state space with no compensa- tion ,primary side compensation and bilateral compensation, and at the mean time establishes relevant simulation models in MATLAB/Simulink to analyze the influences of operation frequency and winding compensation on opera- tion performance of detachable transformer. The simulation result proves the correctness and effectiveness of the models established and the ability of bilateral compensation technology to enhance energy transmission of detachable transformer.
