Abstract

In HVDC system

the AC filter will produce larger inrush current during switching

which will cause damage to the filters

protection misoperation and threat to DC system security.To solve the problem

a simulation based on Monte Carlo algorithm and PSCAD user-definition model has been come up with.Make a lot of simulations about inrush current and the zero sequence current which stands for three-phase unbalanced inrush current at the inverter side.Based on these results

some methods which solve the effect of inrush current has been come up with

like erecting POW

locking the unbalanced protection temporarily.
