IDS based automatic generation method for spacecraft electric simulation model

Abstract

The invention discloses an IDS based automatic generation method for a spacecraft electric simulation model. The method comprises the following steps: based on an established power supply and distribution professional model library, extracting device connection relationships from an IDS set to generate a system model framework, and traversing devices in the model library according to IDS device information and corresponding device connection relationships of models in the power supply and distribution professional model library; judging whether homonymic models exist or not in the model library; and connecting generated model instances to model interfaces and layering the models to finish the automatic generation of the electric simulation model. According to the method, the conversion from IDS to a Modelica simulation model is realized, a power supply and distribution system simulation model framework can be automatically generated, and the power supply and distribution system framework design is evaluated in combination with the model library; and quick simulation verification of a design result is supported to achieve the purposes of verifying and optimizing a power supply and distribution system design scheme and improving the power supply and distribution system performance.

Description

technical field [0001] The invention relates to a technology for automatically generating a simulation model, in particular to an IDS-based method for automatically generating an electrical simulation model of a spacecraft. Background technique [0002] At present, based on the design of the power supply and distribution system of the spacecraft, each model is remodeled in China, and the parameters of the solar array and the battery are redesigned and selected, and how to choose the appropriate power system is determined by manual calculation or based on experience; parameters After the design is completed, only by building a circuit-level model for simulation analysis. There is a lack of a way to quickly and accurately conduct energy strategy analysis and electrical interface verification for the entire on-orbit operation of the spacecraft to verify the rationality of power supply, power distribution, electrical signal transmission, and interface design. Due to the large n...
