A device and method for use in detecting anomalies in wind turbines is provided. The method includes monitoring data acquired by at least one sensor in a first wind turbine, wherein the data is calculated to produce a value for a predetermined amount of time, monitoring data acquired by at least one sensor in a grouping of wind turbines similar to the first wind turbine, wherein the monitored data corresponds to the monitored data of the first wind turbine and is combined for a predetermined amount of time, and comparing the monitored data of the first wind turbine with the monitored data of the grouping of wind turbines. The method also includes generating a sensor error if the monitored data of the first wind turbine deviates more than a predetermined amount from the monitored data of the grouping of wind turbines, and displaying the results of the comparison of the monitored data.

System and method for detecting anomalies in wind turbines

In one embodiment, a packing seal has a plurality of lands that align with annular teeth. Each land has opposite axial sides relative to a rotational axis of a rotary component. Each land also has a recess in at least one of the opposite sides.

Packing seal rotor lands

A steam turbine includes a shaft operatively connecting a first turbine section and a second turbine section. A packing assembly is positioned about the shaft. A first conduit is fluidly connected to the packing assembly. The first conduit is configured to introduce a flow of low temperature, low pressure steam to the packing assembly. A second conduit is also fluidly connected to the packing assembly downstream from the first turbine section and upstream from the first conduit. The second conduit receives a portion of the high temperature, high pressure steam passing into the packing assembly from the first turbine section. A valve is fluidly connected to the second conduit. The valve is configured to be selectively operated so as to allow the high temperature, high pressure steam to mix with the low pressure, low temperature steam in the second conduit.
