Problems solved by technology

With the continuous development of the power system measurement system, the current power system data is composed of multi-source heterogeneous massive dynamic data such as D-PMU, SCADA, distributed power supply, flexible load, and electricity marketing system. The amount of synchronized data is large, and it can be obtained from The amount of extracted information has brought huge challenges to the real-time requirements of power system operation status visualization and data analysis. Simple data text display or visualization without processing can no longer meet the requirements of power industry applications

Description

technical field [0001] The invention relates to a high-frequency power flow data visualization system, which belongs to the technical field of power systems. Background technique [0002] Power system operation status monitoring is an important part of power dispatching, which directly affects the efficiency and quality of dispatching, and power system visualization technology can intuitively display the system operating status. With the continuous development of the power system measurement system, the current power system data is composed of multi-source heterogeneous massive dynamic data such as D-PMU, SCADA, distributed power supply, flexible load, and electricity marketing system. The amount of synchronized data is large, and it can be obtained from The amount of extracted information has brought huge challenges to the real-time requirements of power system operation status visualization and data analysis. Simple data text display or unprocessed visualization can no lon...
