Condition monitoring and fault detection of wind turbines generator

Wind turbine monitoring alarm device consists of sensing unit, data acquisition module, storage unit and comparison unit. The sensing unit is mounted inside the wind turbine to measure first data including temperature, velocity and acceleration. The data acquisition module is electrically connected to the sensing unit for receiving the first data and configured with a transmitter for transmitting the first data. The storage unit is electrically connected to the data acquisition module. The storage unit is provided with a receiver for receiving the first data transmitted by the transmitter and saves the first data as a warning value. The comparison unit is electrically connected to the sensing and memory unit. The unit compares the second data measured by the sensing unit with the first data used as the warning value. The warning indicator issues a warning if the second data is outside the warning range. The alarm indication relating to the fan monitoring alarm described in the comparison unit gives an alarm via audible and visual alarms.
