During the Docking procedures Space station and cargo spacecraft can be connected to the grid for power generation…According to the Eighth Academy of Aerospace Science and Technology, after the core cabin is successfully docked with the cargo spacecraft, in the combined flight mode, in order to ensure the power generation capacity of each cabin and the cargo spacecraft, the core cabin and the cargo spacecraft The cargo spacecraft will be connected to the grid for power supply. At that time, the core cabin can provide up to 2,000 watts of power to the cargo spacecraft. Although compared with the “big family” of the core cabin, the cargo spacecraft has only one third of the power supply capacity of the core cabin, but at critical moments, the cargo spacecraft can also provide about 1,000 watts of power to the core cabin.
“The core cabin supplies power to the cargo spacecraft, mainly considering that the cargo spacecraft is installed at the stern of the core cabin, and the cargo spacecraft’s solar battery wings are small in size and are easily blocked by other combinations of the space station. The cargo spacecraft supplies power to the core cabin for the purpose of Responding to the very few special situations that may occur in the future space station, this also demonstrates the flexibility and reliability of the power supply of the entire space station assembly.” Wang Zhenxu, chief designer of the power supply subsystem of the cargo spacecraft, introduced. In order to receive the 2000 watts of power gift from the core cabin, the cargo spacecraft itself needs to undergo a high-voltage grid-connected adaptation process. In response to the above problems, the developers of the Eighth Academy of Aerospace Science and Technology conducted a series of verification experiments to ensure that the normal operation requirements of the cargo spacecraft are met.
When the cargo spacecraft is connected to the core cabin for power supply, how to deal with the excess electricity? Developers have their own methods. Wang Zhenxu introduced that in the Tianzhou No. 2 cabin, a shunt regulator is installed, through which the excess electricity of the solar battery wing can be shunted. In the future, there will be the challenge of joint power supply of multiple combinations, but the power sub-system can always adapt. This is the intelligent management of the power sub-system in the space station era.
The newly advance variant of the Long March –Chang Zheng 7 Carrier Rocket has more than 130 improvements to make its performance better] This mission is the third launch of the Long March 7 carrier rocket. 4 years have passed since the Long March 7 Yao-2 launches.
