help on simulation of HVDC system

[MASALTA]

Dear Dr. Hanser,
Hi,

My name is Masood and I am currently trying to study the fault detection of HVDC systems. So I decided to look at a simple cases like disconnection of a load part (through break off a cable) and then isolation of the part by help an isolator and circuit breakers.
This example is brought up in an article (Figure 9) : https://www.sciencedirect.com/science/article/abs/pii/S0378779610002166
I am interested in modeling the the scenario of Figure 9 in that paper. That can help me a lot in understanding and modeling the scenarios in OpenModelica.
However as I am new to the simulation with OpenModelica I would like to ask you to help with that example.
This is very vital for my study.
I really appreciate if you could get back to me ASAP.

Many Thanks
Masood
