Hi Dear Mohammad

I think DIgSILENT PowerFactory (14.1.3)  is the best for your simulation

Currently I am using Matlab simulink association with SimPow system and DigSilent Power factory.

besides Matlab, the PSCAD a good option for simulating HVDC, for instance, with better transmission line models.

Pscad/emtdc

For simulation of part head end - DC line - head end is Simplorer ideal.

If you want to see whole process and transient in HVDC system, PSCAD/EMTDC is the best choice. You can make your own user defined model through Fortran and C and This process has already been verified many HVDC system.

For simulation of part head end - DC line - head end is also Portunus ideal.

Yet another vote for PSCAD/EMTDC here. This is _the_ tool that all the major HVDC manufacturers are using for most transient studies in real projects.

PSCAD/EMTDC.

dear all

thank you for your ans 

Dear Mohammad

you can try MATLAB, PSCAD, EMTP-rv, Neplan

good luck
