Abstract

The invention provides a method and system for online parameter adjustment of an electrical network state detection system. The method comprises: first of all, obtaining set parameters of an electrical network state estimation system, performing online acquisition of electrical network operation state parameters after access into an electrical network, then calculating the correction parameters of the electrical network state estimation system, making a comparison between the electrical network operation state parameters and the correction parameters of the electrical network state estimation system and preset standard parameters of the electrical network state estimation system, and determining an assessment effect of the current electrical network by the electrical network state estimation system. According to the invention, in a whole parameter adjustment process, through on-line acquisition of real electrical network data and correction parameters of the electrical network state estimation system and through making a comparison between the data, the correction parameters and the preset standard parameters of the electrical network state detection system, the parameters of the electrical network state detection system can be accurately adjusted, the accurate electrical network operation sate detection by the electrical network state detection system can be ensured, and the safety of electrical network operation is ensured.

Description

technical field [0001] The invention relates to the technical field of power grid systems, in particular to a method and system for online adjustment of parameters of a grid state detection system. Background technique [0002] Energy Management System (EMS) is a computer-based comprehensive automation system for modern power grid systems. The application of EMS makes the scheduling of power grid system dispatchers from experience to analysis, which can effectively improve the safety and reliability of large-scale power generation and ultra-high voltage transmission system of power grid system. [0003] In order to cooperate with the EMS system and better control the power grid system, there are usually multiple grid status detection systems in the power grid. The grid status detection system is used to detect the current status of the power grid. [0004] The power grid state detection system needs to adjust the parameters of the power grid state detection system when dete...
