摘要
在变电站的直流电源系统中,传统的蓄电池核容维护放电方法需要在离线条件下进行,影响变电站设备安全运行。通过研究并联型直流供电系统自动在线核容控制策略,针对大功率并联型直流供电系统提出了蓄电池自动在线全容量核容方法,其中的并联型蓄电池控制模块可以在对蓄电池完成在线核容维护放电工作的同时,保证直流电源系统中的蓄电池不脱离母线。通过Simulink仿真软件搭建电路与控制模块的仿真模型,验证了核容方法的有效性。本研究可为变电站蓄电池的自动在线全容量核容提供参考。
In the DC power supply system of the substation,the traditional battery capacity maintenance and discharge method needs to be carried out offline,which affects the safe operation of the substation equipment.By studying the automatic online capacitance checking control strategy of parallel DC power supply system,this paper proposes an automatic online full capacity checking method for high-power parallel DC power supply system.The method employs parallel battery control module to complete the online capacity maintenance and discharge of the battery,while ensuring that the battery in the DC power system is not disconnected from the busbar.Simulink simulation software is used to build a simulation model of circuit and control module,which verified the effectiveness of the proposed method.The results can provide a reference and theoretical basis for the automatic online full capacity checking of batteries in substations.
