Grid voltage monitoring and prediction system and method based on geographic information system

Abstract

The invention provides a grid voltage monitoring and prediction system and method based on a geographic information system and belongs to the field of grid voltage monitoring technologies. The system comprises a basic information setting module, a map service module and a voltage monitoring and prediction module. The method includes the steps that monitoring data are preprocessed according to historical voltage data of a monitored object and current voltage monitor running status parameters; a voltage prediction model is established; according to the voltage prediction model, the voltage change trend of a monitoring point within future requested time is predicted, if the prediction result exceeds the upper limit range and the lower limit range of voltage of the monitoring point, an alarm prompt is displayed at the position, on a map view, of the monitoring point, and the alarm prompt is also displayed at a corresponding position of a thematic layer where a monitoring point administrative department to which the monitoring point belongs is located. Mapping of grid voltage monitoring and visualization of operating data are achieved, effective early warning is provided for grid voltage abnormities, and grid equipment can be conveniently adjusted, overhauled and scheduled before the abnormities occur.

Description

technical field [0001] The invention belongs to the technical field of grid voltage monitoring, in particular to a grid voltage monitoring and forecasting system and method based on a geographic information system. Background technique [0002] With the rapid development of my country's economy and society, the emergence of high parameters, large capacity, ultra-high voltage and the popularization and application of a large number of new electrical equipment with microelectronic processors and power electronic devices have a great impact on the power supply voltage quality and power supply reliability of the power system. Sexual demands are getting higher and higher. However, due to the access of a large number of nonlinear loads and impact loads, the safety, reliability, and economy of the power system have been greatly affected. Economical and high-quality operation has brought major challenges, and the problem of voltage quality has become an important issue faced by powe...

Problems solved by technology

However, the current traditional voltage monitoring and analysis system only displays the monitoring and analysis results through text or simple graphics, and fails to effectively use the geographic location information of the power grid, resulting in low system visualization, poor information performance, and low management efficiency.
