MATLAB含大规模风电的配电网电压稳定特性分析

Abstract Today's population growth and economic development caused many of the world's countries and regions of energy security, environmental protection and promote social sustainable development concerns.  As the industry for wind power generation is constantly developed and progress, society gradually emerged in the large-scale wind farm and wind farm group. So the special properties of wind power enable distribution network have appeared thereupon many adverse effects, so as the construction and development is restricted of large-scale wind farm. The main task of this article is to study the voltage stability of distribution network with large wind power. The main contents are as follows:

First of all, according to the theory of wind farms the foundation of described model is analyzed. Structure analysis of wind speed and air dynamics model and its component, and then the wake effect theory is analyzed. And then expounds the basic theory of induction generator and doubly-fed generator characteristics, analysis and study of wind farm equivalent problem. To contain the voltage stability of the distribution characteristics of large-scale wind power provides the theory basis for analysis and research.
In the end, based on MATLAB software PSAT is introduced and then use the software PSAT distribution system of large-scale wind power is established and time domain simulation. Through the comparative analysis of the simulation results, paper containing different types of turbine wind farm connected to the distribution network voltage stability of system caused by the adverse effects, and simple analysis of system voltage stability characteristics of is impacted of some of the main reasons.
Keywords: Wind power synchronization;   Wind turbine generator;   PSAT;   Voltage characteristic
