Research on Data Processing Algorithm of the Same Time Section in Substation Based on Time Scale Information Transmission

Due to the complex operating conditions of the actual power system, non-convergence cannot be avoided in the state estimation, and it is difficult to reproduce the results of the section in the inversion. When the measurement and parameter are adjusted, the fluctuation of the qualification rate index will be caused, and the stable operation of the real-time network analysis application system will also be affected. In order to make up the gap in the measurement of the same section of the data in the substation, a method to measure the same section of the time of the power can be studied by using the curve fitting technology and the power balance of the power grid, and at the same time, what kind of faults of the bus line can be judged and the error range of the estimated data can be estimated according to the data. According to the power balance of the power system and the rated power of the node, the data error is judged, and the curve fitting is used to change the data of each node into the curve on the two-dimensional plane. By setting the time interval, the same section measurement of the power data of each node can be realized intuitively.
