This paper is the first of a series of publications detailing the development an AI-based adaptive autoreclosing algorithm. In part 1, a detailed model of the Scottish 132kV Network has been constructed on a real time digital simulator. The system model is discussed, including the network topology, line and source modelling and the DFIG-based wind farm model. An initial investigation on penetration of harmonics from local wind farms is conducted using short circuit faults on two transmission lines in the network. This is necessary to ascertain to what extent wind farms may interfere with the adaptive autoreclosing scheme. As well as validating the model, the results suggest that penetration of harmonics is only significant on lines adjacent to the wind farms.
