摘要
对变电站直流系统失压原因进行分析,发现交流配电单元设计不合理、交流电源运行方式不合理、空开级差配合不当、蓄电池组开路、母联并列开关设计不合理等是引发直流系统失压的主要因素。针对发现问题,从提高充电机的可靠性、完善直流系统接线设计、加强蓄电池科学运维等方面提出解决措施,有效确保了直流系统安全稳定运行。
The causes of loss-of-voltage of the DC system in substations were analyzed.It was found that the unreasonable design of AC power distribution units and AC power supply operation mode,the improper stage difference coordination of air switches,the open circuit of storage batteries,the unreasonable design of bus tie switch and so on were the main factors that caused loss-of-voltage of the DC system.In response to the problems found,solutions are proposed from aspects of improving the reliability of the charger,the connection design of the DC system,and the science-based operation and maintenance of the storage batteries,so as to ensure the secure and stable operation of the DC system.
