论文摘要
电力系统模型的质量和准确性对于基于模拟的研究至关重要,尤其是研究大型系统中的实际稳定性问题。随着广泛监测系统(WAMSS)的部署,高报告利率频率测量为验证频率响应研究中的模型提供了值得信赖的地面真相。本文记录了基于称为FNET/GRIDEYE的WAMS的美国电力系统模型进行检查,调整和验证的努力。四个指标用于定量比较仿真结果和实际测量,包括频率nadir,rocof,沉降频率和沉降时间。在调整了调速器的死胡同和调速器比率之后,模型频率响应显示出显着的改进,并且与事件测量数据匹配。这项工作是调整和验证大型电源系统模型的示例。
The quality and accuracy of power system models is critical for simulation-based studies, especially for studying actual stability issues in large-scale systems. With the deployment of wide-area monitoring systems (WAMSs), the high-reporting-rate frequency measurement provides a trustworthy ground truth for validating models in frequency response studies. This paper documented an effort to check, tune, and validate the U.S. power system model based on a WAMS called FNET/GridEye. Four metrics are used to quantitatively compare the simulation results and the actual measurement, including frequency nadir, RoCoF, settling frequency and settling time. After tuning governor deadband and the governor ratio, the model frequency response shows significant improvement and matches well with the event measurement data. This work serves as an example for tuning and validating large-scale power system models.
