Analysis on the Improvement Strategy of Substation Standby Power Supply with New Energy Access
This paper expounds the operation mode of the distributed new energy generation system connected to the 10kV busbar of the substation,and improves the segmented backup automatic switching logic to reduce the probability of cutting off new energy while ensuring the correct operation of the backup automatic switching.It analyzes the influencing factors of voltage and frequency changes in new energy grid connection points and proposes a new backup and self switching scheme.
