Problems solved by technology
[0002] With the development of wind power generation technology, wind power pitch control technology is developing rapidly. Although there are special drive controllers for horizontal axis wind turbines on the market, this type of drive technology is only controlled by a few domestic and foreign companies, and the procurement cost is extremely high. High, and because the technology is monopolized, the maintenance cost in the later stage is also extremely high, and because the general-purpose drive has a lot of room for choice in terms of cost, model, technical barriers, and brand, the general-purpose drive Pitch control technology is an effective and feasible technical solution. If feasible, this solution can simultaneously expand the range of different types of drives used in the field of wind power pitch control technology

The invention provides a fan pitch control system based on a universal servo driver. As the fan pitch control system adopts the conventional universal servo driver, the cost of the whole fan pitch control system can be effectively reduced. Besides, under the condition of ensuring the stable and safe running of the fan pitch control system, a novel solution is provided for the fan pitch control system, and the application range of the universal servo driver is enlarged.
Description
technical field [0001] The invention relates to the field of pitch control of wind power generation blades, in particular to a fan pitch control system based on a general servo driver.
