摘要： In connection with a wind power generator, it is desirable to safely operate a wind turbine without stopping even when a failure occurs in a measurement sensor such as an aerovane, while a power generation loss is avoided before the completion of the replacement or repair. A remote monitoring system includes a plurality of wind power generators located in the same site, each measuring a status of a peripheral environment by a measurement sensor; and a remote monitoring unit collecting data related to the peripheral environment of each wind power generator. When detecting a occurrence of a trouble in the measurement sensor of at least one wind power generator out of said plurality of wind power generators, the remote monitoring unit transmits data related to the peripheral environment measured by the measurement sensor of a different wind power generator other than the wind turbine generator for which the trouble occurs in said measurement sensor out of the plurality of wind turbine generators, to the wind turbine generator for which the trouble occurs in the measurement sensor. The wind power generator for which the trouble occurs in the measurement sensor continues to operate by using the data related to the peripheral environment which are transmitted from the remote monitoring unit.

摘要： The invention relates to a wind energy installation comprising a rotor (2) provided with rotor blades (21), the angle of attack of said blades being variable by means of a pitch adjusting device. A servomotor (45) connected to a pitch circuit (4) and an emergency circuit (5) is provided for the adjustment of the rotor blades (21), the rotor blades (21) being actuated by means of the pitch circuit (4) during normal operation and by means of the emergency circuit during emergency operation. The emergency circuit (5) comprises an electrical energy accumulator (50), a switching device (51), and connection lines (52) to the servomotor (45). According to the invention, a protection device is provided with a power flow detector module (60) designed to determine whether electrical power flows to or from the servomotor (45), and a discharge module (69) designed to limit the voltage and/or current in the emergency circuit (5) in the event of a power flow from the servomotor (45). The invention enables electrical energy generated from the servomotor (45) to be derived and consumed as a result of a sliding state during emergency operation. In this way, the electrical energy accumulator (50) of the emergency circuit (5) is protected from an unwanted high current charge. This not only extends the service life of the electrical energy accumulator (50) but also improves the system characteristic of the emergency circuit.
