企业输电线路抑制噪声干扰的可行性研究

Research on the Feasibility of Anti-Interferer in the Power Line of Enterprise

在企业输电线路在线监测系统的数据采集过程中,不可避免地混入了各种噪声干扰,为了有效识别和抑制信号奇异性及白噪声,需要采用适当的滤波算法来分析原始信号,并还原其真实信号。分析输电线路监测中可能遇到的多种干扰类型,并根据当前普遍采用的抗干扰方法,设计出数学形态法与小波变换法相结合的抗干扰方法,并设计新的阈值,对该方法进行仿真分析和现场数据试验,取得较好的效果。

In the power line of enterprise online monitoring system,data collection process is very important,it will inevitably mixed with a variety of noise interference.In order to effectively identify and inhibit the signal singularity and white noise,requires appropriate filtering algorithm to analyze the original signal,and restores its true signal.The subject of the power line monitoring may encounter a variety of disturbance and interference based on the current methods commonly used to design Morphological and Wavelet Transformation on the combination of Anti-Interference methods,and designs a new threshold,makes the method of simulation analysis and field data test,and achieves good results.
