Filed:

Oct 28, 2002

Appl. No.:

10/281883

Inventors:

Jason Neely - Albuquerque NM, US
Steven Pekarek - Salem MO, US
Jason Banaskavich - Manchester MO, US
Daniel Stutts - Rolla MO, US

Assignee:

The Curators of the University of Missouri

International Classification:

G01L003/02

US Classification:

073/862333

Abstract:

A torque ripple sensor and method for torque ripple sensing and/or mitigation. A piezoelectric sensor is positioned relative to a motor so that torque fluctuations due to torque ripple of the motor are transmitted to the sensor, resulting in strain of a piezoelectric element. A resulting signal can be amplified and conditioned for determining a magnitude of the torque ripple and/or fed into a feedback loop for applying current control or a counter-torque to the motor for torque ripple mitigation.

Abstract:

Systems and methods for identifying an island condition in a power distribution system and disconnecting distributed generators in the case of islanding. The systems and methods are used to enable reliable detection of island formation with high false-trip immunity, for any combination of distributed energy resources, and for distributed energy resources using grid support functions.
