Doubly-fed wind power control system based on single chip design and research
Abstract
Wind power is a kind of new energy sources,and it is inexhaustible, Because it comes from nature.there is no harm to nature, so the wind will have brilliant prospects.On the basis of previous studies, this essay adopted a new type of doubly-fed motor no-load grid-connection excitation control strategy and did a research on doubly-fed motor penecontemporaneous no-load grid-connection of excitation controller.
This essay has carried on the comprehensive analysis and researched on the doubly-fed wind power generator excitation control system. First of all, based on the analysis of wind turbine characteristics and working principle of doubly-fed induction generator,Using vector transform technology, the doubly-fed motor power generation system is given by coordinate transformation in the mathematical model of the two-phase static coordinate system and based on the stator flux dynamic mathematical model of the synchronous rotating coordinate system. Then we analyzed the quasi-synchronizing parallel control strategy of doubly-fed motor,we established the fine tuning frequency regulating voltage of the machine quasi-synchronizing parallel control method of phase Angle.And then we designed the doubly-fed generator excitation control system hardware.

1.1 课题的研究意义
随着社会的发展，人们需要的能源也越来越多，地球上的一些能源已经满足不了人类的发展，例如重要的能源煤炭和石油，由于现在地球上有限的存储，在传统能源枯竭和生态环境恶化的双重压力下，新能源开发和利用已经成为全世界科学家的热点话题。风力发电作为地球上一种丰富和无尽，无污染的绿色能源已引起越来越多的人的关注[1]。
