Problems solved by technology
[0006] (1) Only estimate the change of the basic network parameters of a single power line. In fact, the change of the channel transfer function is often caused by the simultaneous change of the basic network parameters of multiple power lines. The existing methods are not comprehensive enough in the monitoring information of the power line ;
[0007] (2) It is only suitable for qualitative analysis and cannot quantitatively reflect the change degree of power line status and basic network parameters

The present invention relates to a multi-parameter estimations based power line state monitoring method, including channel attenuation measuring, channel modeling, channel monitoring, channel state analyzing and result reporting. The multi-parameter estimations based power line state monitoring method does not need additional arrangement of a data acquisition device and a communication system, uses power line carrier communication equipment to collect, analyze and transmit the power line state monitoring information, and effectively utilizes the rich resources available to the power line. All these save costs substantially.
Description
technical field [0001] The invention relates to the technical field of power line state monitoring, in particular to a power line state monitoring method for multi-parameter estimation. Background technique [0002] Power lines, an important part of the grid, are a key part of the efficient transmission of electrical energy. Improving the reliability of power cables is crucial to ensure the safe and stable operation of the power grid. Therefore, it is necessary to effectively monitor the state of the power line in order to detect potential problems and hidden dangers in time. [0003] At present, power line condition monitoring methods are divided into two categories: intrusive and non-intrusive. The traditional intrusive method mainly collects information such as current and voltage flowing through the power line network, and connects special sensors in the power line network, senses and records relevant physical quantities through the deployed complete sensor network, an...
