Problems solved by technology

[0004] At present, there is a lack of clear and unified rules for the matching relationship between solar wing arrays and SADA slip rings. Multiple 100V differential pressure gaps are easily formed between SADA power slip rings, and multiple 100V differential pressure gaps increase the risk of power supply safety.

Embodiment Construction

[0026] An optimization method for sub-array and SADA matching to reduce the pressure difference between the rings, such as figure 1 ,Proceed as follows:

[0027] (1) Divide the north and south solar wings into arrays. According to the number of PCU shunt stages and the number of SADA slip ring power rings, the division of north and south solar wing arrays is completed, so that the number of north (south) solar wing arrays is equal to the number of north (south) SADA power rings, and avoids empty SADA power rings. ring, so that the total number of north-south solar arrays is equal to the total number of PCU shunt stages;

[0028] (2) Establish the corresponding relationship between the north and south solar wing arrays and the PCU shunt stages, so that the array number is equal to the shunt stage number, the north solar wing corresponds to the odd number shunt stages, the south sun wing corresponds to the even number shunt stages, and the shunt numbers are from the inner panel...

Abstract

The invention relates to an optimization method for sub-array and SADA matching for reducing pressure difference between rings, which belongs to the technical field of communication satellites. The present invention comprises the steps of: dividing the north-south solar-wing sub-array; establishing the one-to-one correspondence relationship between the north-south solar-wing sub-array and the PCU distribution level; through (2) the one-to-one correspondence relationship between the north-south solar-wing sub-array and the PCU distribution level , establish the matching relationship between the south and north solar wing sub-arrays and the SADA power rings on the south and north solar wing sail drive mechanisms, and control the number of gaps in the SADA power rings to the minimum; the gap is between two adjacent power rings The potential difference is not zero, so that the number of 100V differential pressure gaps of the SADA slip ring is minimized, so as to reduce the risk of power supply safety caused by the differential voltage between the rings.

Description

technical field [0001] The invention relates to a sub-array and SADA matching optimization method for reducing pressure difference between rings, and belongs to the technical field of communication satellites. Background technique [0002] Each sub-array of the solar wing is connected to the shunt regulator (S3R) in the PCU through the SADA power slip ring, forming a one-to-one correspondence between the sub-array-SADA power slip ring-S3R. When the solar array works in the shunt state, the array is connected to the entire star ground, and the corresponding SADA power slip ring potential is 0V; when the solar array works in the power supply state, the array supplies power to the entire star load, and the corresponding SADA power The slip ring potential is 100V. When one of the two adjacent SADA power slip rings is at 0V potential and the other is at 100V potential, a 100V potential difference will be formed between the rings. The 100V differential pressure gap has certain ri...
