Abstract
Provided is an electric machine health monitoring system that includes an electric machine, a data acquisition component, a local transmitter, a communications network, and a remote diagnostic unit that is configured to receive the time sequenced operational information, asset performance, and health status indicators from a local transmitter. The remote computational unit comprises software that is configured to perform diagnostic analysis of time sequenced operational information to determine the asset performance and health status of the electric machines.
Claims20
A health monitoring system for an electric machine, comprising:
- a first electric machine;
- a first local diagnostic unit connected with the first electric machine, wherein the first local diagnostic unit includes a local computational unit which is configured to receive a high bandwidth first set of operational data from the first electric machine and perform a first local diagnostic test on the high bandwidth first set of operational data to generate a first local diagnostic test result;
- and
- a remote diagnostic unit coupled with the first local diagnostic unit, wherein the remote diagnostic unit includes a remote computational unit which is configured to receive the first local diagnostic test result from the first local diagnostic unit, wherein the remote computational unit is further configured to perform a remote diagnostic test using the first local diagnostic test result to obtain an electric machine health status indicator;
- wherein a low bandwidth requirement maintains a data fidelity during a transmission of the first local diagnostic test result from the first electric machine to the remote diagnostic unit.
A method for determining performance and health status of an electric machine, comprising:
- acquiring a high bandwidth first operational data set from a first electric machine using a first local diagnostic unit connected with the first electric machine;
- performing a first local diagnostic test on the high bandwidth first operational data set using the first local diagnostic unit to generate a first local diagnostic test result;
- transferring the first local diagnostic tests result generated by the first local diagnostic unit from the first local diagnostic unit to a remote diagnostic unit coupled with the first local diagnostic unit;
- and
- performing a remote diagnostic test on the first local diagnostic test result using the remote diagnostic unit;
- wherein a low bandwidth requirement maintains a data fidelity during a transmission of the first local diagnostic test result from the first electric machine to the remote diagnostic unit.
