摘　　要：在光伏发电项目的前期规划设计过程中,项目的装机规模及无功补偿容量配置往往会存在偏差,导致工作量大幅增加。提出对光伏发电系统进行有功功率/无功功率(P/Q)分析的方法,以求有效确定光伏发电项目装机容量和无功补偿容量。以境外某地面集中式光伏发电项目为例,在确保其能够满足并网点的功率要求,且具备调整功率因数的能力的前提下,进行P/Q分析,将基于项目损耗计算得到的并网点功率与实测值进行对比后发现,此方法得到的结果的精准率接近99.5%,证明了项目配置的合理性和准确性。In the early planning and design process of PV power generation projects,there are often deviations in the installed capacity and reactive power compensation capacity configuration,resulting in a significant increase in workload.This paper proposes a method for analyzing the active power/reactive power(P/Q)of PV power generation systems,in order to effectively determine the installed capacity and reactive power compensation capacity of PV power generation projects.Taking a centralized PV power generation project overseas as an example in this paper,while ensuring that it can meet the power requirements of the grid-connected point and has the ability to adjust the power factor,P/Q analysis is conducted.After comparing the grid-connected point power calculated based on project losses with the measured values,it is found that the accuracy of the results obtained by this method is close to 99.5%,proving the rationality and accuracy of the project configuration.
