The reactor can suppress voltage fluctuations in the power grid and improve power quality.During the operation of the reactor,a large amount of losses will be generated by the winding and core.If the heat generated by these losses cannot be discharged in time,it will affect the normal operation of the reactor and even cause damage to the converter.In this paper,by establishing an electromagnetic-thermal-fluid coupling simulation model,the heat dissipation performance of the integrated water and electricity reactor and the separated water and electricity reactor is studied.Multi-physics field coupling simulation can accurately obtain the size and distribution of reactor losses.It provides a basis for accurately calculating the overall loss inside the converter,reduces the design margin of the converter cooling system,and thus achieves the purpose of cost reduction and efficiency increase.The research results show that the proportion of cooling air heat exchange of the integrated water and electricity reactor is 1.2%,and the proportion of cooling air heat exchange of the separated water and electricity reactor is 13.6% .
