Abstract: A wind farm supervision monitoring system includes: a data collection unit configured to collect data about a status monitoring of each wind turbine from at least one site server; an abnormality status detection unit configured to detect an abnormality status of each wind turbine based on the collected data about the status monitoring and issue an alarm; a wind data management unit configured to early detect a fault of each wind turbine and or monitor performance of each wind turbine based on the data about the status monitoring or the data about the abnormality status; and a supervision unit configured to manage a turbine operation status and operation and maintenance of each wind turbine and provide information for establishing an operation and maintenance plan for the detected abnormality status of the wind turbine.

Abstract: A compressor includes a compressor screen mounted on the outer circumferential surface of a compressor disk or the inner wall of a compressor casing. The compressor screen is positioned between a row of compressor blades and a row of compressor vanes to stabilize airflow by regulating the amount of air flowing in the compressor. The compressor screen is formed of annular plate having openings through which the compressed air flows, arranged in a pattern to smoothly regulate the flow of air. The compressor screen may be variously configured, for example, to facilitate installation or to guide the flow of air using a tapered surface or a directionality of the openings or a flow guide. A gas turbine includes a combustor, a turbine, and a compressor employing the compressor screen.

Abstract: A gas turbine comprises a strut assembly including an inner ring; an inclined member including a first end connected to the inner ring, a second end positioned opposite the first end, and a flange extending radially inward from the second end; an oil sump mounted to the second end or the flange; a thrust bearing fixed to the oil sump; and a thrust collar extending radially from a rotor, wherein the inclined member has an aperture portion formed therein, the aperture portion is positioned in an upper portion of a region between the thrust bearing and a journal bearing, and the aperture portion has a width and a circumferential length greater than at least the journal bearing. The gas turbine has the feature that the journal bearing is easily withdrawn and the total weight of the gas turbine is reduced.
