摘要
本文重点研究了利用小波变换方法检测电力系统中暂态电能质量扰动的原理,并对短时电压变动和电磁暂态等暂态电能质量扰动进行了仿真。理论研究和仿真分析证明,该方法能够实现对暂态电能质量扰动快速又准确的检测,为暂态电能质量扰动的评估和治理提供了依据。
This paper analyzes the detection principle of transient power quality disturbances of power net- work by wavelet transform, makes a simulation research on the power quality disturbances, such as the short-term fluctuation of voltage and the electromagnetic transient. The theoretical analysis and simulation research show that transient power quality disturbances can be detected roundly, real-timely and accurate- ly by the wavelet transform, to provide the basis for the assessment and management of transient power quality disturbances.
