Abstract

The invention discloses a wide-area-measurement-system (WAMS)-based power grid safety and stability visualization method. The method comprises the following steps of: converting data to operations of angle stability visualization, voltage stability visualization, dynamic stability visualization, frequency stability visualization, thermal stability visualization, stability three-dimensional visualization and comprehensive stability visualization through a computer graphical display technology; effectively carding and integrating wide area measurement, monitoring, analysis, early warning and decision results so as to display the results to a dispatcher by visual means; and monitoring, actively early warning, actively analyzing and actively providing auxiliary decision results in real time, and providing key information needed by the dispatcher so as to realize a multi-angle multi-dimensional intuitive and visualized data display mode. Therefore, control over power grid operating conditions is strengthened by the dispatcher, existing abnormal or potential accident potentials are penetrated timely, and scheduling operation is developed from an experience type to analysis and intelligent types.

Description

Technical field: [0001] The invention relates to a visualization method, in particular to a visualization method for power grid security and stability based on a wide-area measurement system (WAMS). Background technique: [0002] With the continuous progress of the Three Gorges Project and the national Internet and other projects, the scale of the power grid has become larger and larger, and the operation mode has become more and more complex. How to strengthen the reliability of the large power grid has become a concern. Wide-area measurement technology is one of the most active fields in the frontier technology of power system in recent years. Wide Area Measurement System (WAMS) is a system based on synchrophasor measurement technology, with the support of modern high-speed communication network, to monitor and analyze the operation status of the power system in a wide area, and to serve the real-time control and operation of the power system. The wide-area measurement sy...
