Problems solved by technology

[0003] At the same time, with the deepening of design verification, it is necessary to establish simulation models according to different stages to meet the needs of simulation verification at different levels. However, under normal circumstances, a simulation model can only be used for simulation verification of a single design stage. For differe

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] A method for constructing a spacecraft energy system model based on the Modelica model, which includes the following three parts:

[0022] 1) Design decomposition of the energy system model;

[0023] The energy system is an extremely important physical system in a spacecraft. It undertakes the task of supplying power to the entire spacecraft and involves all the electrical equipment on the spacecraft. The equipment is modeled separately, and the workload will be extremely large. Through research and analysis, it can be found that many components of the aerospace energy system have the same characteristics, different types of equipment can be classified according to certain rules, and different types of energy system structures can also be combined according to certain models.

[0024] For the interface, such as: a battery pa...

Abstract

The invention discloses a Modelica model-based spacecraft energy system model construction method. The method comprises the following steps of: 1, carrying out design composition on an energy system model; 2, constructing a Modelica language-based energy system model library; and 3, demarcating and verifying the Modelica language-based energy system model library. The spacecraft energy system model construction method is oriented to objects and equations and has favorable reusability and hierarchy; and through applying the method, the difficulty of model development can be greatly reduced, the reusability of models can be remarkably improved, the energy system design period can be effectively shortened, the dynamic design ability can be enhanced and the design efficiency can be improved.

Description

technical field [0001] The present invention relates to the design field of spacecraft energy system (also called power supply and overall circuit system, power supply and distribution system, hereinafter referred to as energy system), and mainly relates to a construction method of spacecraft energy system based on Modelica model. Because there are many types of spacecraft energy systems, the model library described here only involves the energy system of battery-solar array combination. Background technique [0002] At present, the design of spacecraft energy systems, especially in the overall design stage, generally adopts the method of combining empirical formulas and typical parameters to perform static energy balance and power flow calculations. However, under normal circumstances, the power generation and load power of the energy system change dynamically. , and is closely related to task scheduling and the design of other subsystems, its dynamic design is extremely ...
