Design Challenges for Numerical SSR Protection

摘要：

　　We report on the development of a modern numerical SSR protection to replace an existing analogue relay that no longer could be adapted to changing operating conditions.The development is based on knowledge gained from field recordings of SSR events at the prospective site.From this and some theoretical considerations,it was possible to design a new protection function that is more reliable than previous generations of SSR relays.
