Spacecraft orbit control load power consumption autonomous control method

Abstract

The invention relates to a spacecraft orbit control load power consumption autonomous control method, which comprises the following steps: taking a satellite-borne computer with a flight management function as a core for autonomously controlling load power consumption during spacecraft orbit control, and operating an autonomous control strategy to set corresponding limit power and control the power-on and power-off states of an electric load; enabling the satellite-borne computer to autonomously generate an instruction for controlling the power-on and power-off of the electric load and send the instruction to the power distribution equipment with a power-on and power-off control function on the electric load; and enabling the power distribution equipment to receive and respond to the instruction to set an electricity load power-on and power-off switch state. According to the method, time-sharing work autonomous scheduling and power consumption limit autonomous control of short-term loads or pulse loads such as an orbit control engine, an attitude control engine, a heater and load equipment in the spacecraft orbit control period are achieved, and the problems that in the spacecraftorbit control period, the load power consumption is too high or changes too much are solved, and the problem of power utilization safety of the spacecraft is prevented.

Description

technical field [0001] The invention relates to the electrical field of spacecraft, in particular to a method for autonomously controlling power consumption of spacecraft orbit control loads. 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 is strong, and the working sequence is becoming more and more complex. The requirements for the power supply and distribution system of the spacecraft are getting higher and higher. . Spacecraft equipment can usually be divided into long-term load, short-term load and pulse load according to the characteristics of power consumption. Long-term loads refer to loads whose power basically does not change during flight, such as attitude control computers, gyroscopes, measurement and control transponders and other electrical equipment. Short-term loads refer ...

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
