### I'd like to know how to adjust the firing angle in the monopole HVDC transmission system Cigre Benchmark in pscad?

Hello dear all

I'd like to know how to adjust the firing angle in the control system of Cigre benchmark, Monopolar LCC HVDC system . I'm actually using cigre benchmark model that is pscad with my parameters. Unfortunetely, the simulation results are diffrerent than my calculation results. I've seen the place to introduce the value of gamma minimum which is the extension angle but in terms of firing angle I didn't see anything. Can anyone help me. The value of the firing angle is 18 degrees.
