摘　　要：本文以24k Hz/100k W的电磁热储能系统为研究对象,系统采用电磁感应加热的方式,将由新能源发电系统产生的清洁电能转化成为热能,并将这些热能加以利用或者存储在水中。首先应用Ansoft-Maxwell对感应加热模型进行涡流场仿真分析得到磁场分布,利用得到的磁感应强度计算流体场热源。然后应用Ansys/Fluent对感应加热模型进行三维流体温度场仿真分析。感应加热系统的电源设计在电磁热储能系统中有着至关重要的地位,应用Matlab/Simulink对感应加热电源串联谐振电路进行建模仿真分析,得到谐振状态下的电路特性曲线,给出了PLL锁相环信号、PWM全桥逆变触发信号等波形,为电磁热储能系统的感应加热电源的研究和开发提供了一定理论依据。24k Hz/100 k W electromagnetic thermal energy storage system is took as the research object in the paper. The system turn the clean electrical energy from the new energy power generation system into heat by electromagnetic induction heating, and the heat will be used or stored. Firstly, Ansoft-Maxwell is used to get the magnetic induction intensity of the electromagnetic induction heating model in eddy current field. Then Ansys/Fluent is used to analysis the fluid temperature field of the electromagnetic induction heating model. The power supply design of induction heating system plays a vital role in the electromagnetic thermal energy storage system. Matlab/Simulink is used to model and simulate the series resonance circuit of electromagnetic induction heating power source, the circuit characteristic curve of the resonance condition is got. The simulation shows the PLL phase-locked loop signal, the PWM full bridge inverter trigger signal. The research provides a theoretical basis for the induction heating power supply of electromagnetic thermal energy storage system.
