风电场内集中无功补偿容量的设计与研究

风力发电的间歇性导致风电场电压波动较大,需要装设足够的无功补偿装置。目前对于风电场内集中无功补偿的计算和分析少有涉及,风电场接入系统设计,均是按照相关并网准则要求进行。提出风电场内各环节无功损耗的计算和分析方法,通过算例验证所提方法的有效性;依据风电场无功补偿相关技术规定所确定的风电场内集中无功补偿装置容量,在具体工程应用中具有一定的局限性。

Design of Centralized Reactive Power Compensation Capacity of the Wind Farm

Due to the great voltage fluctuation resulted from wind power intermittence, adequate reactive power compensation needs to be installed. At present the reactive power compensation calculation and analysis for the wind farm are rarely conducted, and the grid-connection design of wind farms is carried out in accordance with related guides. This paper presents the calculation and analysis method of the reactive power loss of the wind farm, and proves the effectiveness of the method through case study. It has some limitations to determine the reactive power compensation capacity of the wind farm according to related technical requirements.
