Controlled Switching for Overvoltage Mitigation by Sultan Al-Saiari is a document available to read on EtoBox.
What is Controlled Switching for Overvoltage Mitigation about?
The document discusses a controlled switching strategy to mitigate switching overvoltages in transmission lines by optimizing the circuit breaker contact opening and closing instants. Specifically: 1) Controlled switching aims to find the optimal circuit breaker contact opening/closing instants when the voltage across the contacts is zero to minimize overvoltages. 2) A simple zero crossing algorithm is used to determine the optimal instants and control the circuit breaker operation accordingly. 3) Case
