摘要：
In this paper we present the importance of upgrading power stations with numerical protection relays. We will study the gravity and the economic impact of a power system fault when it appears and it is not cleared by old protection devices. Also we will compare how an old protection scheme works when it clears a power fault with how modern numerical protection relays work. The trip decision and the actual circuit breaker open times will be compared and analyzed.
