Real time sensing method of grounding resistance state in distribution network based on time series clustering algorithm

In order to ensure the operation safety of distribution network grounding resistance, it is necessary to detect and modify the node resistance fault value in time. A real-time sensing method of distribution network grounding resistance state based on time series clustering algorithm is proposed. Firstly, combining with the principle of feature acquisition, the admittance value of distribution network is collected and regulated. After removing the data interference information, the voltage sag value of distribution network grounding resistance is modified to ensure the real-time perception effect of distribution network grounding resistance state, realize the accurate collection of difference data, and complete the real-time perception of distribution network grounding resistance state. Finally, the experiment shows that the real-time sensing method based on time series clustering algorithm has higher accuracy in the practical application process and fully meets the research requirements.
