Problems solved by technology

Most of the current load monitoring is carried out by means of load strain gauges. The strain gauges can effectively measure the load of the parts to be tested, but the overall load of the unit cannot be evaluated. To effectively measure and evaluate the overall load, you need A large number of strain gauges, but the strain gauges are consumables, and the installation requires a lot o

Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples.

[0020] The method for on-line load monitoring and active load reduction control of a wind power generating set provided in this embodiment includes the following steps:

[0021] 1) Data collection and processing

[0022] Install the Beidou positioning system on the unit, use the Beidou positioning system to collect the displacement, speed and acceleration of the unit cabin in the front and rear directions, and then output it to the main control system (PLC) of the unit, and the main control system calculates the thrust in the front and rear directions of the tower f x , where the calculation formula is as follows:

[0023]

[0024] In the formula, M, D, and K are the mass, damping, and stiffness coefficients of the unit tower, respectively; x are the acceleration, velocity and displacement values ​​in the front and rear directions of the nacelle, respectively;

[0025]...

Abstract

The invention discloses a wind generating set load online monitoring and active load shedding control method. The method comprises the steps that 1, a Beidou navigation system is installed on a set, set engine room forward and backward displacement, speed and acceleration information is collected, and output to a set main control system, and forward and backward thrust Fx of a tower is calculatedthrough the main control system; 2, according to the calculated thrust Fx, the load applied to the set is evaluated, and active load shedding control is conducted. Accordingly, the applied load monitoring scheme is easy to apply, maintenance is facilitated, operation load of the set can be monitored online in real time, effective load shedding control can be conducted according to the monitored set operation load, the phenomenon that the set operates under high load for a long time is prevented, and then the set operation safety and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of load monitoring and load reduction of a wind power generator set, in particular to an online load monitoring and active load reduction control method of a wind power generator set. Background technique [0002] Since clean energy is an environmentally friendly renewable energy, the state has given great support to its development in recent years, and its proportion of consumption in the energy industry has increased year by year, showing a strong momentum of development. As a kind of clean energy, wind power has also maintained a steady growth in its installed capacity. With the deep mining of wind resources, especially the vigorous development and utilization of offshore resources, the unit capacity of the unit continues to increase, and the diameter of the impeller is also getting longer and longer. Under the development trend of wind and fire at the same price, it is imperative to reduce the cost of t...
