Power distribution network characteristic analysis system based on PMU data

Abstract

The invention discloses a power distribution network characteristic analysis system based on PMU data. The system comprises a real-time dynamic data acquisition unit which acquires power grid real-time operation data through a PMU; the real-time dynamic data receiving unit is used for receiving real-time power grid measurement data and integrating the data through the real-time dynamic data integration unit to form input data and files of the dynamic performance evaluation module; the dynamic performance evaluation unit comprises a multi-level partition module, a weight distribution module and a performance evaluation module; the dynamic cooperative control unit performs power distribution network dynamic characteristic optimization control through the cooperative controller based on the evaluation result; meanwhile, the integrated data is sent to the historical data storage unit and is presented through the man-machine interaction unit and the visualization unit; based on wide-area measurement dynamic data provided by the PMU device, the time delay problem is eliminated, meanwhile, a multi-level evaluation architecture is adopted, the data analysis process is simplified, simple and rapid online analysis and evaluation are achieved, and the evaluation speed and efficiency are improved.
