摘要

大多数相关的PQ干扰研究都是通过先进的数学概念来解决的,没有可能在合成信号上测试这些技术。本文介绍了一个在MATLAB中实现的新应用程序,该程序可以设置不同的合成信号、PQ干扰和白噪声。然后计算FT、STFT、CWT、DWT和去噪信号。此外,应用程序可以通过RESTful web服务连接到任何设备,并查询存储在智能传感器中的数据。这种应用的新颖之处在于它允许连续监测FT, STFT, CWT, DWT和去噪信号。

Simulation of power quality disturbances through the wavelet transform
Most of the related PQ disturbances studies are addressed exclusively through standing advanced mathematical concepts without possibility to test these techniques over synthetic signals. This paper presents a new application implemented in MATLAB that has been developed to set up different synthetic signals, PQ disturbances and white noise. Afterwards, FT, STFT, CWT, DWT and denoised signals are calculated. Moreover, the application can connect to any device via RESTful web service and query for data stored in smart sensors. The novelty of this application lies in the fact that it allows to monitor FT, STFT, CWT, DWT and the denoised signals continuously.
