Design and evaluation of a new type of protection for wind farms

EMTDC is a nonreal time transient simulator designed by the Manitoba HVDC Research Centre. It incorporates a user-friendly, CAD style interface called PSCAD that allows the user to model a network by interconnecting pre-defined graphical icons that represent the components of the power network. This approach ensures that it is unnecessary to write any direct code, provided the existing models within the EMTDC libraries are acceptable. However, this does not preclude the user from defining their own custom models as graphical icons in an EMTDC component library. This paper indicates how the relative flexibility and userfriendliness of EMTDC, has allowed a new protection for wind farms to be modelled and tested within a simulator
