How to create a variable resistor as a function block in PSCAD V4.5?
Hello, I need to design a system with a variable resistor. I have a system of variable resistance that includes a mathematical function. In v4.5, I could not define this function with blocks containing only input and output. 1- Is there a ready-made block for PSCAD v4.5? 2-Or how can I do it? Thanks.
