Embodiment Construction
[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0024] The present invention aims at the problem that the existing wind turbine state monitoring method cannot monitor the specific inclination degree of the tower, and provides a wind turbine overturning monitoring system. Simultaneously conduct real-time vibration monitoring in the same direction, and conduct real-time analysis and statistics on the detected data to find out whether there is any inclination of the tower beyond the normal range. In the following, for the convenience of description, the direction of the main shaft of the wind turbine is collectively referred to as the X-axis direction, and the direction perpendicular to the main shaft of the wind turbine is collectively referred to as the Y-axis direction.

The invention provides a wind turbine generator toppling monitoring system which comprises a statistic analysis and calculation unit, two first vibration monitoring units and two second vibration monitoring units. The two first / second vibration monitoring units are arranged on two preset test points of a tower in the X-axis / Y-axis direction respectively, and used for carrying out vibration monitoring on the preset test points in the X-axis / Y-axis direction in real time, and sending X-axis / Y-axis vibration data of the preset test points to the statistic analysis and calculation unit. The statistic analysis and calculation unit is used for analyzing and calculating the received X-axis / Y-axis vibration data of the two preset test points to obtain toppling data of the tower. The X-axis direction is the direction of a main shaft of a wind turbine generator, and the Y-axis direction is perpendicular to the direction of the main shaft of the wind turbine generator. The wind turbine generator toppling monitoring system can monitor the toppling data of the tower in real time, bring convenience to management and examination for a manager, and effectively prevent the tower from toppling down.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind turbine overturn monitoring system. Background technique [0002] In recent years, with the continuous shortage of coal, oil and other energy sources, new energy power generation, especially wind power generation, has become a major research focus in the power industry. Wind turbines are key equipment in wind power generation systems and need to be maintained continuously during use. For a long time, the method of planned maintenance has been adopted for wind turbines, that is, routine maintenance is performed on wind turbines after a certain period of operation. This maintenance method cannot fully and timely understand the operation status of the equipment, and this kind of after-the-fact maintenance is due to insufficient preparation in advance, resulting in long maintenance work and serious losses. [0003] The tower is the main supporting device in the...
