Abstract

The invention relates to a combination on-orbit energy management method based on energy balance analysis. The method comprises the steps that S1. a spacecraft model is constructed and connected as acombination model, and the flight scheme of the combination model is acquired; S2. a power generation capacity curve is acquired according to the combination model and the flight scheme, and a load working curve is acquired according to the flight scheme; and S3. the energy balance state of the combination model is assessed based on the power generation capacity curve and the load working curve. The volt-ampere characteristics of all the battery strings on the sailboard can be accurately calculated through the algorithm of introducing the combination model and the flight scheme to be combinedto acquire the shielding shape of the sailboard in the flight process to obtain the power generation capacity, and the energy balance situation can be accurately analyzed through combination of the load demand and the energy system design so that the power generation capacity error caused by conventional average shielding or the shielding rate can be eliminated, and the power generation capacity of the sailboard can be accurately predicted.

Description

technical field [0001] The invention relates to an energy management method, in particular to an on-orbit energy management method for an assembly based on energy balance analysis. Background technique [0002] During the in-orbit flight of the combined spacecraft in orbit, the sailboards have many shapes and large shapes, and the sailboard control mode and attitude control mode are complex, resulting in large changes in power generation capacity. The energy balance analysis method of a traditional single spacecraft can no longer meet the energy balance analysis requirements of an on-orbit combined spacecraft, especially the power generation capacity calculated by the average shading or shading rate in the traditional method is difficult to accurately make the calculated power generation capacity and the actual The power consumption of the load is matched, so that there is a large error in the calculated power generation capacity, which leads to an increase in the error of e...
