How can i adjust input parameter in MMC_HVDC example Model (nominal Frequency) Hello. I am studying ptp mmc hvdc example model. However, I am having a problem adjusting the parameters and I am asking a question The example model has its base frequency set to 50 Hz, so we are trying to change it to a 60 Hz system. In the case of the'MMC NLC' block among the converter blocks, it is applied by changing the input parameter to 60Hz, but in the case of the control block, even if an input is given at 60Hz, the value of 'Freq' measured internally is 50Hz and does not change.
So, when I check, enter the value of'Norminal frequency (Freq)' as 60 in'Edit parameters' of'control block', press the save button, and check again, the rated frequency is changed back to 50Hz. In'Edit Definition' of the control block, set both the upper and lower limits of'Norminal frequency (Freq)' to 60Hz and change the input value to 60Hz to perform the simulation, then'Input parameter (freq=50) is below range (min =60).' A warning message appears.
In summary, even if the frequency input parameter of the control block is entered at 60Hz, pressing the save button causes the problem to return to 50Hz again. I need help. Before save (Frequency is set 60Hz)
After save (again 50Hz)
