Modeling method, system and equipment of dynamic reactive power compensation device and medium

Abstract

The invention discloses a modeling method, system and equipment for a dynamic reactive power compensation device and a medium. The modeling method comprises the following steps of: constructing an initial stable model, calculating to obtain actually measured power data according to data corresponding to an actually measured waveform, and adjusting transient parameters of the initial stable model by adopting actual controller parameters to obtain an intermediate stable model; and operating the intermediate stable model in a voltage ride-through fault scene, outputting fault power data, and if the fault power data is not equal to the actually measured power data, adjusting the transient parameters to obtain a target stable model corresponding to the dynamic reactive power compensation device. The technical problems that the modeling mode of the existing dynamic reactive power compensation device is based on a universal theoretical model, verification of actual operation data is not passed, the actual operation characteristics of the dynamic reactive power compensation device cannot be accurately simulated, and the applicability of the generated dynamic reactive power compensation device model is low are solved. A target stable model with high applicability can be constructed according to the actually measured waveform and the actual controller parameters corresponding to the power grid end.
