III.  DATA COLLECTION AND EXPERIMENTAL RESULTS
3 数据采集和实验结果
The data selection should meet the requirement of the analysis and evaluation for a PV system. The functions of the monitoring and test system should be verified by an on-site test in grid-connected PV system. 
对光伏系统而言,数据的选择应满足分析和评价的要求。监测系统的功能应在光伏并网系统的现场试验中验证。
A.  Data Collection 
3.1 数据采集
The parameters to be measured by the monitoring system in real time are shown in table 1. The parameter selection is based upon the standard IEC 61724 and within the framework of the International Energy Agency Photovoltaic Power System (IEA PVPS) Program Task . The sampling interval for parameters is set as 5 seconds and stored as 1 minute average. All parameters will be continuously measured during the specified monitoring period at a common rate.
实时监测系统中需要测量的参数如表1所示,参数的选择参照于IEC 61724标准和国际能源机构的光伏发电系统(IEA PVPS)计划任务书中的框架。参数的采样间隔设置为5秒,并且每1分钟存储1次,因而所有的参数将在指定的监测期间以同种速率被连续测量。
TABLE I.   PARAMETERS TO BE MEASURED IN REAL TIME
表1  实时测量参数
Various derived parameters related to the PV system’s energy and performance may be calculated from the recorded monitoring data using sums, averages, maxima, minima, and ratios over the measuring period τ, (such as days, weeks, months and years) by the data acquisition software. Derived parameters are shown in table 2. 
与光伏发电系统性能相关的的各种衍生参数可由数据计算采集软件计算,具体计算方法有:求和,平均,取最大值及最小值,和测量周期τ比率(例如天,周,月和年)。所导出的参数示于表2。
