Based on the response of large grid-wide trend line integrated quantitative evaluation method

The present invention provides a power grid based on the response of the whole trend line integrated quantitative evaluation method, comprising: S1, from the SCADA system, EMS system to obtain network topology configuration information, and establish a correspondence between the grid elements of the system WAMS; S2, from SCADA system, EMS acquires the current system, or system operating mode WAMS data flow or to obtain various power flow or transient failure envisioned time domain data from the DSA system; S3, from the perspective of the response data track is divided into macro-steady state (or quasi steady-state) and transient (or dynamic) two operating scenarios, online-oriented manner on the grid nodes statically stable situation assessment, by way of the online unit of the grid for transient stability assessment of the situation. When starting configuration are static and transient comprehensive assessment element from stage heat stability, an acceptable range and the amount of the electric system-level stability three angles, and improve the comprehensive assessment of the whole situation of reasonable indicators; tasks using parallel method for improving the whole situation integrally assessment efficiency.
