A real-time data quality analysis method and application for power systems based on balance calculation

Abstract

The large-scale real-time data of the entire network provides complete and reliable basic data for global analysis and decision-making business scenarios, improves the accuracy of online analysis and calculation, and supports the integrated online analysis and decision-making of the large power grid. In the actual operation process, due to various reasons such as model parameter maintenance errors, abnormal equipment operation, and delayed startup of new equipment, data quality levels fluctuate, affecting the accuracy and real-time performance of calculation results. To further improve the quality of real-time data, balance analysis and calculation tools are used to accurately evaluate the quality of basic data in various power grids through real-time balance calculations and statistical analysis of calculation results for equipment such as power plants, topology buses, lines, and main transformers. This provides technical support for operation and maintenance personnel to promptly identify data quality issues and make targeted corrections.
