Abstract

In this paper

in order to improve the insulation reliability of the module

and achieve its optimized design

the method of insulation test on flexible HVDC converter valve power module is studied

and the electric field simulation analysis method of the flexible HVDC converter valve power module is proposed.The calculation model of power module is established through analyzing the working principle of the power module.Then according to the insulation test of the flexible HVDC converter valve power unit and electric field simulation method

the corresponding boundary conditions is settled.Afterwards utilizing the electric field simulation software Elec Net

the electric field distribution characteristics in the internal of the power unit are calculated under insulation test voltage.Thus the position of the maximum electric field intensity and the corresponding maximum values of the electric field intensity are obtained.The validity and correctness of the method are verified by comparing the results of the insulation test.It is proved that this method can guarantee the safety and reliability of the power module through the insulation test.
