Method and system for power swing detection in a generator |
| 摘要 |
A generator protection device is provided. The generator protection device includes a safety factor estimation module configured to estimate a safety factor as a function of a terminal voltage (VS) of a source-end generator, and a swing center voltage (SCV) between the source-end generator and a receiving-end generator. The system further includes a comparison module configured to compare the estimated safety factor with a defined safety threshold limit, and a decision module configured to trigger an alarm or a generator circuit breaker trip action or both, based on the comparison between the estimated safety factor and the defined safety threshold limit. |

1. A generator protection device, comprising:
a safety factor estimation module configured to estimate a safety factor as a function of a terminal voltage (VS) of a source-end generator, and a swing center voltage (SCV) between the source-end generator and a receiving-end generator; a comparison module configured to compare an estimated safety factor with a defined safety threshold limit; and a decision module configured to trigger at least one of an alarm or a generator circuit breaker trip action, based on the comparison between the estimated safety factor and the defined safety threshold limit. |
