针对电力电子化电网电气量的宽频特征,设计了多功能宽频测量装置。基于高速同步采样优化,该装置集成宽频振荡检测、同步相量测量和宽频(间)谐波测量等功能。该装置综合运用暂态量、相量、有效值等算法模型,可提高对于不同信号结构宽频电气量的监测能力,兼顾平稳和非平稳工况,实现0~2 500 Hz范围内工频、非工频分量和振荡功率的全面检测,为宽频电气量的产生机理、传播路径、分析控制等研究提供针对性的数据。文中实现的多功能宽频测量装置已通过测试并试点应用。

this paper designs a multi-functional wide-frequency measurement device. Based on high-speed synchronous sampling
the device is optimized to integrate such functions as wide-frequency oscillation detection
synchrophasor measurement and wide-frequency (inter)harmonics measurement. The algorithm models of transient variables
phasors and effective values are synthetically used to improve the monitoring and detection ability of wide-frequency electric variables with different signal structures. Considering both stable and non-stable conditions
the comprehensive detection of power frequency
non-power frequency components and oscillation power in the range of 0~2 500 Hz is realized
which provides targeted data for the research of generation mechanism
propagation path
analysis and control method of wide-frequency electric variables. The multi-functional wide-frequency measurement device realized in this paper has passed the test and been applied in pilot projects.
