METHODS AND SYSTEM FOR BALANCING TURBINE ROTOR ASSEMBLIES
First Claim
1. A balancing system for use in balancing a rotatable member, said system comprising:
- a plurality of vibration sensors positioned to sense vibrations of the rotatable member;
a controller assembly communitively coupled to said plurality of vibration sensors, said controller assembly configured to;
receive data from said plurality of vibration sensors; and
determine an imbalance in the rotatable member based on the received data; and
a balancing assembly coupled to the rotatable member, said balancing assembly configured to wirelessly communicate with said controller assembly, said balancing assembly configured to modify a weight distribution of the rotatable member in response to a command transmitted from said controller assembly.

Abstract
A balancing system and method for reducing imbalance in a rotatable member of a machine is provided. The system includes a plurality of vibration sensors positioned about a stationary portion of the machine, a controller assembly communitively coupled to the plurality of vibration sensors, and a balancing assembly coupled to the rotatable member, said balancing assembly configured to wirelessly communicate with said controller assembly, said balancing assembly configured to modify the weight distribution of the rotatable member in response to a command wirelessly transmitted from the controller assembly. The controller assembly is configured to receive data from the plurality of vibration sensors and determine an imbalance in the rotatable member using the received data.
