| Abstract: | The cause of loss of synchronism protection RXZK malfunction when a phase to phase fault took place on the HV busbar in Beilun Power Plant was analyzed. The method to solve the problem was given. It was pointed out that the effect of system faults on the measurement criteria of the protection of the generator during abnormal condition should be fully considered to avoid malfunction of the protection. |
