System and method for synchronous machine health monitoring

摘要

A method, system and computer program product for monitoring health of a synchronous machine is provided. The method includes receiving (402) a plurality of phase voltage values and a plurality of phase current values. The method then computes (404) a negative sequence voltage (Vn) based on the plurality of phase voltage values. The method also computes (406) one or more operating parameters based on at least one of the plurality of phase voltage values and the plurality of phase current values. The method retrieves (408) from a data store, one or more known Vn based on the one or more operating parameters. The method then computes (410) a machine health indicator based on the computed Vn and the one or more known Vn, and raises (412) an alarm based on the machine health indicator.
