基于暂态录波数据的负荷建模方法研究

文章提出了一种基于暂态录波数据的负荷建模方法,首先导入故障录波器录到的录波文件,分析录波文件的数据有效性,然后对有效的录波文件进行负荷建模,辨识负荷模型参数。负荷建模系统能够对五种负荷模型进行参数辨识,得到最优负荷模型,并通过动模实验验证了负荷建模方法的正确性。最后简单的介绍了负荷建模软件,软件采用QT编程,功能完善,包括基本信息配置、模型辨识、曲线拟合、模型验证和数据导出等功能,并提供与电力系统仿真软件BPA的数据接口。

Load Modeling Method Research Based on Transient Wave Record Data

This paper proposes a load modeling method, based on transient recorded wave data. First import the recorded fault wave file, analyze the file data validity. Then load modeling for effective recorded wave file, identify load model parameters. Load modeling system can carry on the parameter identification of five kinds of load model, get the optimal load model, and through dynamic model test results verify the accuracy of load modeling method. Finally introduces the load modeling software simply, the software use QT programming, function is perfect, including basic information configuration, model identification, curve fitting, model validation, data export and other functions, and provide data interface with BPA.
