中文摘要：
主要比较了国内外常用的光伏发电与风力发电的并网技术标准,分别从并网方式,电压偏差、电压波动和闪变、频率、谐波、直流注入等电能质量指标,保护与控制以及风电场低电压穿越等方面进行了详细的分析。指出了国内现有标准存在的不足,在并网技术标准的制定过程中,应综合考虑并网容量以及接入电网的电压等级等因素。
英文摘要：
The standards of grid-connection technology commonly used at home and abroad for photovoltaic and wind power generations are compared.The grid-connection mode,the power quality indicators including voltage deviation,voltage fluctuation and flicker,frequency,harmonics and DC injection,the protection and control and the low-voltage ride-through of wind farm are analyzed in detail.The inadequacies of existing domestic standards are pointed out and it is suggested that the output capacity of grid-connected system,the voltage level of grid and other factors should be considered during the development of grid-connection technology standards.
