Research on Real-Time Data and State Acquisition Methods for Low Voltage Grid Nodes
Aiming at the shortcomings of low automation degree of grid node data collection and poor condition monitoring ability of traditional methods,the real-time data and state acquisition method for low voltage grid nodes based on power terminal account is researched.Firstly,the collection and monitoring architecture including terminal account module and server monitoring module is constructed.Then,the terminal account module configured at the substation end is used to acquire real-time data of grid nodes;the server monitoring module located at the control center is used to call and acquire real-time data of the grid.Finally,the T-type gray correlation is applied to extract the nodes to be calibrated,and the direct trend similarity between the nodes to be calibrated and the rest of the nodes is measured by the Pearson correlation coefficient,and the obtained abnormal grid node data are corrected back to within the correct threshold,thus completing the state monitoring of the real-time data of the low voltage grid nodes.The experimental results show that the method can accurately complete the information acquisition and state monitoring of the grid nodes with high smoothness.The overall acquisition and monitoring performance is best of this method when the threshold is set at 0.4.
