| 摘 要： | 将概率论中相关性分析方法应用到不同功率下电能质量的相关性研究中。通过搭建风电场接入系统的仿真模型并进行相关性分析，表明新能源并网节点的电压偏差程度主要是由系统的电压运行水平、新能源注入功率和负荷大小决定的。在系统运行背景不变的条件下，风电场接入抬高并网节点电压的程度与风电场注入系统的功率有很大的相关性。在此基础上，本文...

| Abstract: | In this paper,correlation in probability theory is applied to the correlation study of power quality under different sizes of power.Based on the simulation model of a wind farm accessed into system and correlation analysis,it shows that the voltage deviation at grid node of distribution network is mainly determined by the system normal operation level,the input power of new energy source and the size of loads,and there is a very strong correlation between the raising voltage caused by accessing wind farms a... |
