Title:
STATE MONITORING SYSTEM AND WIND GENERATOR SYSTEM WITH THE SAME
Document Type and Number:
Japanese Patent JP2017173076
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain oscillation measurement data with sufficiently reduced noise in a state monitoring system which monitors a state of a wind generator system.SOLUTION: A first oscillation sensor 110 measures oscillation of a bearing 60. A second oscillation sensor 120 is provided to measure background noise received by the first oscillation sensor 110 and is installed so as not to receive the oscillation of the bearing 60. A data collection device 80 receives a first signal being a measurement signal of the first oscillation sensor 110 and a second signal being a measurement signal of the second oscillation sensor 120 and outputs a third signal obtained by subtracting the second signal from the first signal, as data indicative of the oscillation of the bearing 60.SELECTED DRAWING: Figure 2
