Efficiency analysis and heating structure design of high power electromagnetic thermal energy storage system

It is an important way to relieve environment problems by using wind, solar and other clean energy sources. The paper takes 24 kHz/100 kw electromagnetic thermal energy storage system as the research object. 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, use Ansoft-Maxwell to get the magnetic induction intensity of the electromagnetic induction heating model in eddy current field, analyze the relation between current penetration depth and the current frequency. Then use Ansys/Fluent to analysis the fluid temperature field of the electromagnetic induction heating model and analyze the characteristics of temperature. Use temperature characteristics to do different test in order to get the best scheme. Finally, prove the validity of simulation by experiment, the research provides a theoretical basis for the development and application of electromagnetic thermal energy storage system.
