Resumen:
The number of substations with breaker-and-a-half configuration have significantly increased over the last decades due to their flexibility and high reliability. When the linebreaker is in maintenance, the electricity is supplied through the middle-breaker. When a fault occurs on the line during the previous operating state, the fault is isolated by opening the middlebreaker. However, there is no auto-reclosing algorithm implemented to automatically reclose this middle-breaker, and continue the normal operation of the system. Therefore, this paper introduces an effective, and implementable algorithm for auto-reclosing the middle-breaker in a substation with breaker-and-a-half configuration, when the line-breaker is in maintenance. The control algorithm uses only binary signals from both switches on both the line-breaker and the middle-breaker. These signals can easily be …
