配电系统的校准可分为两个不同的任务，即收集和分析现场数据。现场数据的收集可进一步分为物理数据和操作数据的收集。为了建立和确认计算机模型的基础数据文件，需要收集物理数据，如线尺寸、长度、条件、高程等。校准需要操作数据。应收集运行数据，如系统需求、现场压力测量、现场泵曲线开发、现场流量测量、储罐液位、消防流量测试、C系数测试等，以便在特定时间点记录和分析每个部件。在开发配电系统的校准计算机模型时，使用了各种方法、工具和工作水平。

The calibration of a distribution system can be separated into two distinct tasks, the collection and the analysis of field data. The collection of field data can be further separated into the collection of physical and operation data. The collection of physical data, such as line sizes, lengths, conditions, elevations, etc., is necessary to establish and confirm the base data file for the computer model. The operational data is required for calibration. The operation data, such as system demands, field pressure measurements, field pump curve development, field flow measurements, tank levels, fire flow test, C-factor tests, etc., should be collected such that each component can be recorded and analyzed at specific points in time. A variety of methods, instruments, and levels of effort are utilized in developing a calibrated computer model for a distribution system.
