The invention discloses a modeling method of a source load decoupling model for an independent power system with a pulse load, and relates to the technical field of motor control models. The method comprises the following steps: constructing a coupling equivalent model of a synchronous generator and a pulse load by utilizing a simplified equivalent model of the synchronous generator; introducing three bridge arm switching functions of a rectifier to derive a source load coupling relation between the alternating current and direct current side voltage and current of the coupling equivalent circuit model of the synchronous generator and the pulse load; enabling the power supply to be equivalent to an ideal voltage source by enabling the internal impedance of the alternating current side to be equivalent to the direct current side, and constructing a source-borne decoupling model. The method not only can reflect the influence details of the source-load coupling on a DC side operation mechanism, but also can reduce the analysis difficulty.
Description
technical field [0001] The invention relates to the technical field of motor control models, in particular to a source-load decoupling model modeling method of an independent power system with pulse loads. Background technique [0002] The current research on the operating characteristics of PL-IPS (IPS refers to an independent power system: Isolated Power System, PL-IPS refers to an independent power system with a pulsed load: IPS with Pulsed Load), is all about the source (generator set) Or the load terminal (rectifier pulse load) is modeled and analyzed separately, without in-depth consideration of the mathematical correlation and coupling law between the source and load. The source-load coupling relationship of PL-IPS will not only affect the power output and performance of the pulse load itself, but also affect the operating characteristics and stability of the system and power supply. However, considering the source-load coupling will increase the difficulty of theore...
