Abstract

The present application provides a noise self-adaptive method and equipment in the process of collecting electricity information data. The method includes: collecting current signals at multiple frequency points; wherein, the current signals include power consumption information and communication signals; testing each of the current signals to obtain the split ratio of each of the current signals and the corresponding frequency point information; select a current signal that satisfies the preselection principle according to the split ratio and the frequency point information, and obtain a target current signal; extract a noise signal corresponding to each of the target current signals, and determine the corresponding noise signal according to the noise signal Amplitude; according to the amplitude, the frequency point of the target signal is determined by using an adaptive principle. In the embodiment of the present application, through the principle of self-adaptation, starting from the minimum noise amplitude, the frequency points corresponding to the preset number of noise signals are used as the target signal frequency points, so as to reduce the influence of the background noise collected by the power consumption information on the signal injected into the power system. influences.

Description

technical field [0001] The present application relates to the field of power line carrier communication, in particular, to a noise adaptive method and device in the process of collecting electricity information data. Background technique [0002] The power grid refers to the whole composed of substations of various voltages and transmission and distribution circuits in the power system, including power transformation, transmission and distribution, and its main task is to transmit and distribute electric energy. At present, in order to reduce the erection and operation costs of communication lines, a communication scheme using existing power lines is proposed in grid communication technology, and reliable narrowband or broadband communication is realized by means of power line carrier communication technology. [0003] However, because the power line itself is not a special line tailored for communication, there are strong interference signals and sudden interference noise i...
