【摘要】 为了解决大型风电场并网后带来的诸多电能质量问题,在综合分析了风电场电能质量特点的基础上,研究了一种基于虚拟仪器和MATLAB的风电场电能质量模拟监测系统,对风电场的电网电压波动、闪变、电压偏差、频率、谐波、三相不平衡度进行监测。使用LabVIEW Simulation Interface Toolkit与MAT-LAB/Simulink的结合,通过仿真验证了该系统的正确性、可行性,具有一定的推广价值。更多还原

【Abstract】 To solve some power quality problems after connection of large wind plants to power grid,considering characteristics of power quality of wind power plants,this paper studies a wind plant’s simulation monitoring system of power quality based on virtual instruments and MATLAB.This system supervises fluctuations,flicker,voltage deviation,frequency,harmonic wave and three-phase imbalance of voltage.Combining LabVIEW Simulation Interface Toolkit with MATLAB/Simulink,the simulation proves that the system is valid,feasible,and worthwhile to popularize.更多还原
