Problems solved by technology
On the other hand, the status monitoring data of the distribution network and even the power transmission and transformation equipment have the characteristics of slow change. It is difficult to ensure high measurement accuracy in complex on-site conditions. There will inevitably be noise and noise in the measurement results. Uncertain factors (such as operation, short-term channel error, etc.), so the analysis and diagnosis of its real-time value is of little significance, and the trend analysis of its long-term data is an effective means to reflect its insulation status. However, there is still a lack of data basis for trend analysis of long-term data in the existing technology

The invention relates to a multi-dimensional monitoring data processing and analysis method and device. The method comprises the steps: carrying out the data compression processing of a large amount of multi-dimensional monitoring data generated by a power distribution network intelligent sensor through a dimension reduction method, extracting useful data information on the premise of guaranteeing the data trend, deleting redundant data, and reducing the dimension of the data; carrying out data reduction and data curve fitting on the data subjected to dimension reduction; and finally, performing trend analysis on the restored data. According to the method, compression and data trend analysis are performed on the on-line monitoring data through the data processing method aiming at the characteristics of large on-line monitoring information amount, information redundancy and data gradual change of the power distribution network, so that rapid processing and effective utilization of the power distribution network data are realized, and powerful data support is provided for state evaluation of power distribution network equipment.
Description
technical field [0001] The invention relates to the technical field of on-line monitoring of distribution network data, in particular to a method and device for processing and analyzing multi-dimensional monitoring data. Background technique [0002] The on-line insulation monitoring technology of distribution network power equipment is one of the important technical means to ensure the safety of distribution network equipment and improve the reliability of power supply. The application of large-scale sensing equipment has brought about a large accumulation of distribution network operation data. At the same time, the online monitoring data of the distribution network contains a large amount of interference noise. deal with. On the other hand, the status monitoring data of the distribution network and even the power transmission and transformation equipment have the characteristics of slow change. It is difficult to ensure high measurement accuracy in complex on-site condit...
