Monitoring system and method for monitoring running performance of power grid system in real time

Abstract

The invention provides a monitoring system and method for monitoring running performance of a power grid system in real time. The system comprises one or more monitoring computers used for receiving mass data flow including synchronization phasor measurement values of second-level timestamps, used for storing running performance data of an electric power system, configured to monitor reliability indexes, power gird operation indexes, electric power production indexes and electric power transmission indexes of a wide-area interconnected network, configured to monitor events in data flow of the wide-area interconnected network in real time and analyze and predict future operation conditions, configured to execute event logic detection, and configured to display event analysis results. The method includes the first step of receiving the mass data flow from the wide-area interconnected network, the second step of detecting data in the received data flow, the third step of conducting event analysis, the fourth step of conducting performance evaluation on the grid system, and the fifth step of visually displaying event related measurement results and event analysis results. By means of the system and the method, the managing and scheduling capacity of the whole electric power system can be remarkably improved, and running reliability of the electric power system is effectively ensured.

Description

[0001] technical field [0002] The invention relates to the field of electric power technology, in particular to a monitoring system and method for real-time monitoring of the operating performance of a grid system. [0003] Background technique [0004] In many industries, it is necessary to be able to monitor, track and predict in real time. These industries include power systems, natural gas pipelines, water supply systems, transportation systems, chemicals, industrial process control, infrastructure protection, safety monitoring, etc. [0005] In the power industry, electricity is provided to users through four typical stages: production, transmission, distribution and final use. The transmitted electricity is usually distributed by the utility or the utility company that manages the electricity distributed locally. Transmitting and distributing power systems require multiple devices for power management and control of the power system, including dynamic voltage sup...

Problems solved by technology

Although all these organizations at different levels are involved in the production, transmission, distribution, and supervision and control of the power grid, there is no unified integrated system for real-time monitoring and management of the entire power system, resulting in low efficiency of management and scheduling of the power system and accidents. The hidden danger investigation rate is low...
