DC Power Supply and Maintenance of Substations in the New Era Power System
The maintenance of DC power sources in substations has become a key factor in ensuring the stable operation of the power grid.As an indispensable part of the substation,DC power supply bears significant responsibility for power supply reliability and safety.Starting from elaborating on the DC power supply system in substations and its common problems,this paper delves into the operation and maintenance measures of DC power supply in substations in the new era,covering key aspects such as the reasonable selection of battery packs,standardized operation of DC power supply,regular inspection and maintenance of the system,strengthened training of personnel skills,and optimization of control methods.Through these analyses,the aim is to provide some reference for the efficient operation and reliable maintenance of DC power supply in substations,and promote the optimization,upgrading,and sustainable development of DC power supply in power system substations.
