Abstract
A system includes an excitation system configured to regulate one or more outputs of a power generating system. The excitation system includes data processing circuitry configured to obtain an electrical voltage measurement and an electrical current measurement associated with the power generating system, a transformer failure detection system configured to detect an abnormality associated with the electrical voltage and electrical current measurements as an indication of a possible transformer failure, and a failure detection deactivation system configured to deactivate the transformer failure detection system based at least in part on whether the abnormality comprises one of a first condition or a second condition.
Claims20
A system, comprising:
- an excitation system configured to regulate one or more outputs of a power generating system configured to provide power to an electrical power grid, comprising:
- data processing circuitry configured to obtain an electrical voltage measurement and an electrical current measurement from the power generating system;
- a transformer failure detection system configured to detect an abnormality associated with the electrical voltage and electrical current measurements as an indication of a transformer failure;
- and
- a failure detection deactivation system configured to deactivate the transformer failure detection system based at least in part on whether the abnormality comprises one of a first condition or a second condition.
A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions to:
- obtain an electrical voltage and an electrical current measurement from a power generating system configured to provide power to an electrical power grid;
- detect an abnormality associated with the electrical voltage and electrical current measurements as an indication of a transformer failure;
- and
- deactivate a transformer failure detection system based at least in part on whether the abnormality comprises one of a first condition or a second condition.
A system, comprising:
- an excitation system configured to regulate an output of a power generating system configured to provide power to an electrical power grid, comprising:
- a transformer failure detection system configured to detect an abnormality from an electrical voltage measurement and an electrical current measurement as an indication of a transformer failure;
- and
- a failure detection deactivation system configured to:
- calculate a magnitude of the electrical current measurement;
- and
- deactivate the transformer failure detection system when the magnitude of the electrical current measurement exceeds a predetermined current magnitude threshold.
