摘要
目前,变电站采用的双充双电直流电源系统供电方式在电网和蓄电池同时故障时将导致变电站控制和保护电源失电,从而影响变电站电网设备的安全运行。因此,提出了一种基于双向DC/DC变换器的智能型母联装置,使两段直流母线互为备用,提高了变电站直流系统的可靠性,保证电网安全运行。
At present,the power supply mode of the dual-charged dual-DC power supply system used in the substation will cause the substation control and protection power supply to lose power when the grid and battery are faulty at the same time,thus affecting the safe operation of the substation power grid equipment. Therefore,an intelligent bus device based on bidirectional DC/DC converter is proposed to make two DC bushels standby to each other,improve the reliability of DC system of substation and ensure the safe operation of power grid.
