Wind generating set load online monitoring and active load shedding control method

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...

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 of manpower and material resources, which increases the operation and maintenance costs of the unit. This method is not advisable for long-term real-time online monitoring of the overall load of the unit.

Similarly, more reliable fiber grating strain gauge sensing equipment can be used for load monitoring, but the cost is relatively expensive, and it is not suitable for mass production.
