摘要

1 q& H8 L' ~% ?, g  `1 u风能作为一种绿色能源，开发利用已有较长的历史和较成熟的技术，造价上也开始具备与化石燃料能源竞争的条件。同时风电的飞速发展也使得人们不得不考虑风力发电对电网稳定性的影响，由于电力网络的复杂性和数据量巨大，采用人工分析和研究是十分繁琐的，因此必须借助于计算和仿真软件来实现。
本次设计从风的研究出发，对风进行了评估分析，从风到风力机再到风力发电机，实现了从机械能到电能的转化，用数学的语言描述各部分的组成，然后进行模拟仿真。对电力系统的分析从不同的角度进行考虑。非线性的方法进行分析计算，对含有风电场的电力系统进行动态的潮流计算，然后对风电场节点的电压、频率进行一定的分析。研究风电场对系统的频率、及电压的波动进行分析，得出结果。
本文也详细阐述了MATLAB和电力系统分析综合程序的原理和建模方法为风模型的建立﹑风力发电机模型的建立及风力发电并网后进行潮流计算提供了工具。

Abstract

$ `4 i. p4 W& |% D# F! h( Z2 ~As a clean and renewable energy's development and utilization have gone through a long period , and the technology has become more and more perfact . in recenty years , it has been able to compete against other fossil fuel for its cost . On the other hand , with wind power developing ,people have to conside impact to power system stability when wind power brings in grid .Because of complexity and huge date ,power system analysis cannot be proceeded by manual method ,but by analysis and simulation soft to carry out .

This design sets out from the research of the breeze, proceeding to the breeze the valuation analyze, arriving again the fan driven generator from breeze to the wind force machine, realizes from mechanical energy to the conversion of the electric energy, describe each part ofconstitutive enzymes with the language of the mathematics, then proceed the analog simulation. Consider to the analyse of the electric power system from the different angle progress.The method progress analyse of
nonlinear computes, to dynamic tide current in progress in system in electric power calculation that contain the breeze electric field, then to the voltage, frequency progress of the breeze electric field nodal point certainly of analyse, study the breeze electric field to the frequency of the system, and the wave motion progress of the voltage analyzes, getting a result.

In this essay ,the principle and idea of MATALAB and POWER
