We are having a schoolproject were we are going to implement the functionality of some Components of a Hydro Power station directly in the PLC. The Project is mainly to implement the generator breaker synchronisation. To do this we have to compare the line/bus-voltage with the generator voltage. The frequency, phase and voltage have to be the same. We are Programming Structured Text. Does anyone have some tips on how to solve this problem?
I'm not sure this has something to do directly with a PLC, but I'm sure you will need a dedicated PLC Api.
And, No, I didn't understand the purpose of your question.
