Autonomous Control Method of Spacecraft Orbit Control Load Power Consumption

Abstract

The invention relates to a method for autonomous control of load power consumption in spacecraft orbit control, using an on-board computer with flight management function as the core for autonomous control of load power consumption during spacecraft orbit control, and setting the corresponding limit power in the operation autonomous control strategy And control the power-on and power-off status of the electric load; the on-board computer independently generates the command to control the power-on and power-off of the electric load, and sends it to the power distribution equipment with the function of controlling the power on and off of the power load; the power distribution equipment receives and responds to the command Set the status of the electric load plus power off switch. The method of the present invention realizes the autonomous scheduling of time-sharing work and the autonomous control of the electric power limit for short-term loads or pulse loads such as orbital control engines, attitude control engines, heaters, and load equipment during the orbital control period of the spacecraft, and solves the problem during the orbital control period of the spacecraft. Problems such as excessive load power consumption or excessive changes can prevent the safety of spacecraft power consumption.

Description

technical field [0001] The invention relates to the field of spacecraft electrical, in particular to an autonomous control method for the power consumption of a spacecraft orbit control load. Background technique [0002] With the rapid development of aerospace technology, the performance of spacecraft has been greatly improved, the equipment and power consumption on the spacecraft have increased sharply, the load equipment has become more intense and the working sequence has become increasingly complex, and the requirements for the power supply and distribution system of the spacecraft have become higher and higher. . Spacecraft equipment can usually be divided into long-term load, short-term load and pulse load according to the power consumption characteristics. Long-term load refers to the load whose power basically does not change during the flight, such as the attitude and orbit control computer, gyroscope, measurement and control transponder and other electrical equip...

Problems solved by technology

On the other hand, we should also pay attention to the pulse load working conditions, such as the working condition of the engine, which may cause the instantaneous peak power to increase by hundreds of watts or thousands of watts. Such extreme conditions may cause large transient voltage fluctuations on the power supply bus, exceeding the normal operation of the equipment. range, there are potential safety hazards in electricity use
