Embodiment 1

[0028] figure 1 It is an exemplary schematic diagram showing a system for monitoring the state of a tower of a wind power generating set according to Embodiment 1 of the present invention.

[0029] refer to figure 1 , the system for monitoring the state of the tower of the wind power generating set in the embodiment of the present invention includes a first satellite signal acquisition device 110 , a plurality of second satellite signal acquisition devices 120 - 1 - 120 -n and a satellite signal processing device 130 .

[0030] The first satellite signal acquisition device 110 is set at a predetermined position in the wind farm, such as the aforementioned reference station. Preferably, the first satellite signal acquisition device 110 is set in a lightning protection area of ​​the wind farm to prevent it from being struck by lightning.

[0031] In addition, the site selection of the reference station (correspondingly, the first satellite signal acquisition device 110) has th...

Embodiment 2

[0069] Figure 5 It is a flow chart showing the method for monitoring the state of the tower of the wind power generating set according to the second embodiment of the present invention.

[0070] combined reference Figure 5 and figure 1 , in step S510, the first carrier signal transmitted by the specified satellite is received by the first satellite signal acquisition device 110 arranged at a predetermined position in the wind farm, a first reference signal is generated with reference to the first carrier signal, and the first carrier signal and The first reference signal is sent to a predetermined satellite signal processing device; and the designated satellite is received synchronously with the first satellite signal collection device through the second satellite signal collection devices 120-1~120-n respectively arranged on the nacelle of the wind power generating set The transmitted second carrier signal is used to generate a second reference signal with reference to th...

Abstract

The invention relates to a system and a method for monitoring a state of a tower cylinder of a wind turbine generator system. The system comprises first satellite signal acquisition equipment, second satellite signal acquisition equipment and satellite signal processing equipment. As the satellite signal acquisition equipment is arranged on an observation station and a reference station, and the real-time phase differential treatment is performed for acquired satellite carrier signals, the shape change of the tower cylinder is monitored with high precision in real time; and meanwhile, one satellite signal acquisition equipment only needs to be installed on the observation station, so that the wind power plant construction fund is saved.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a system and method for monitoring the state of a tower of a wind power generating set. Background technique [0002] With the continuous increase of human demand for resources and the decrease of non-renewable energy such as coal and oil, the development and utilization of renewable resources has become the general trend. As a renewable resource, the status of wind energy in human life has gradually increased. It has become the main way for human beings to develop wind energy on a large scale. [0003] The wind turbine mainly includes a tower, a nacelle on the tower, a generator in the nacelle, and blades installed on the generator. As the supporting structure of the entire wind turbine unit, the tower plays a key role in the safe and stable operation of the unit. Swing, the swing of the tower will cause problems such as tower radial displacement and foundation settlement, ...
