Breaker node overvoltage after breaker open to clear fault
I am simulating a fault in offshore grid interconnected wind farm. After the fault is cleared by breakers the nodes asscociated with the breakers sees a very high voltage and gradually the voltage is beconing zero instead of zero after the breaker open. Can any boday help how to fix this problem. The voltage seen after breaker opening is also not sinusoidal wave shape. The voltage plot is attached for reference.
