A method and device for evaluating the effect of AC-DC coordinated control based on multi-source data

Abstract

The present invention relates to a method and device for evaluating the effect of AC-DC coordinated control based on multi-source data, including: monitoring and obtaining the action information of the safety and stability control device in real time; At the receiving time t of the action information, the AC / DC line measurement data from t-2 to t and the AC / DC line measurement data from t to t+3 are extracted from the relational database; the action strategy table file corresponding to the action information is obtained and Analyzing, obtaining the action start condition, control start value and control data; judging whether the action of the safety and stability control device satisfies the action start condition according to the AC / DC line measurement data; obtaining the evaluation result by comparison; the method provided by the invention can convert the power grid model information , WAMS measurement information, security control action information, and security control device strategy table file information are analyzed comprehensively after data integration, so as to form a scientific evaluation conclusion on the effect of AC and DC coordination control.

Description

technical field [0001] The invention relates to the technical field of power system dispatching, in particular to a multi-source data-based AC / DC coordination control effect evaluation method and device. Background technique [0002] At present, the power transfer under the condition of large-scale power flow faults in the power grid has a wide range of influence, and is under great pressure to limit the scale of load shedding in the National Document No. 599. It is necessary to understand and master the operating status of the main AC and DC channels, and to master and coordinate the power transfer of the regional power grid. After measures are taken, the power grid is in a stable state. The basic function of online monitoring of the status information of the safety control device has been realized in the currently running system, but the evaluation of the AC-DC coordination control effect in the AC-DC system has not yet been realized. Contents of the invention [0003] A...

[0002] The power transfer under the condition of large-scale power flow faults in the current power grid has a wide range of influence, and is under great pressure to limit the scale of load shedding in the national document No. 599. It is necessary to understand and master the operating status of the main AC and DC channels, and to master and coordinate power transfer in regional power grids After the measures are taken, the power grid is in a stable state. The basic function of online monitoring of the status information of the safety control device has been realized in the currently running system, but the evaluation of the AC-DC coordination control effect in the AC-DC system has not yet been realized.
