Embodiment Construction

[0013] The present invention provides a comprehensive control system for large-scale wind power generators, which is characterized in that it includes:

[0014] Wind group data acquisition unit, data analysis model, self-tuning controller, feedback controller and feedforward controller;

[0015] The wind group data acquisition unit is used to collect wind field data; the data analysis model can analyze wind field resources; the self-tuning controller performs self-tuning by obtaining online I / O data; In the wind speed range, there are optimal power point tracking and minimum mechanical action of the transmission system, and the multi-objective function with optimal output power and minimum control variation is calculated; the feed-forward controller is used to predict the wind field conditions in advance and compensate for wind speed disturbances.

[0016] Further, the wind field data acquisition unit includes wind speed, wind direction data, power, airflow intensity, vibratio...

Abstract

The invention provides an integrated control system for a large wind power generating unit. The integrated control system is characterized by comprising a wind group data acquisition unit, a data analysis model, a self-tuning controller, a feedback controller and a feedforward controller; and by using wind field data, the integrated control system controls fan power, and the system control capability is optimized.

Description

technical field [0001] The invention relates to a wind power generation system, in particular to a large-scale wind power generating set integrated control system and a preparation method thereof. Background technique [0002] Environmental protection is a major issue facing mankind now, and it is an important guarantee for the sustainable development of a country and national economy. Wind energy is one of the important clean energy. As the source of the power system, wind power is actually not very stable. At the same time, it is accompanied by low energy density, uneven distribution, randomness, intermittent and uncontrollable characteristics. The voltage control and active power dispatching caused by large-scale wind power grid connection And system stability and other issues are becoming more and more prominent. At present, most wind turbine controllers are based on model control, but the disadvantages are that the mathematical model is difficult to establish accurate...
