Method and device for determining out-of-step operation of a synchronous condenser
By acquiring the status data of the synchronous condenser, the ultimate reactive power and ultimate terminal voltage are calculated and compared to determine the operating status of the synchronous condenser. This solves the problem of synchronous condenser running out of sync and achieves convenient detection and cost reduction.

AI Technical Summary
Existing technologies are insufficient to effectively determine the out-of-synchronization operation status of synchronous condensers. Prolonged out-of-synchronization operation may lead to equipment damage and require additional equipment, increasing costs.
By acquiring the preset state data of the synchronous condenser, the reactive power, terminal voltage and excitation electromotive force are calculated, the limiting reactive power and limiting terminal voltage are calculated and compared, and the operating state of the synchronous condenser is confirmed based on the comparison results, thus realizing the out-of-synchronization judgment without the need for additional equipment.
It enables convenient detection of synchronous condenser out-of-synchronization operation status, reduces costs, and is applicable to synchronous condenser out-of-synchronization determination.
