Problems solved by technology

Among them, the passive type does not require external energy input, and has a better suppression effect on some small vibrations, but the suppression effect on relatively large vibrations is not obvious
The active system has the best vibration reduction effect, but requires the input of external energy, and the cost is high

Abstract

The invention provides a suspended vertical-axis wind driven generator set which comprises fan blades, a wind driven generator set, a suspended platform and a cable rope. The suspended platform is fixed on the seabed through the cable rope. The wind driven generator set is installed inside the suspended platform. The fan blades are installed on a generator rotation shaft of the wind driven generator set. The wind driven generator rotation shaft is perpendicular to the sea level. The suspended vertical-axis wind driven generator set is characterized in that a hybrid vibration reduction control device and a measurement and control system are further installed in the suspended platform. The hybrid vibration reduction control device consists of a passive vibration reduction device and an active vibration reduction device. The measurement and control system tests an included angle formed by the suspended platform and a horizontal plane or the vibration frequency of the suspended platform, the passive vibration reduction device performs individual vibration reduction on the generator set when a measurement value is smaller than a control amplitude value, and the active vibration reduction device and the passive vibration reduction device are kept cooperative during working and jointly perform vibration reduction on the generator set when the measurement value is larger than the control amplitude value.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a suspended vertical axis wind power generator set. Background technique [0002] Wind energy is a kind of renewable energy, and its utilization has many forms, among which wind power generation is the most important form of wind energy utilization. Today, when traditional energy sources are being exhausted, wind power generation has been widely valued all over the world. my country's "Twelfth Five-Year Plan" clearly states that it will vigorously develop wind power, especially offshore wind power. It can be seen that the construction of offshore wind power will open up new growth points for the development of renewable energy. [0003] Offshore wind turbines are mainly suspended, mainly because they are relatively simple to install and easy to move and manufacture. And compared with the tower unit, the cost is relatively low. As a kind of offshore wind turbine...
