摘要: 针对传统变电站蓄电池核容效率低、故障影响范围大等问题,提出一种基于分组并联架构与双向LLC谐振变换技术的在线核容系统。将108节2 V串联电池组重构为9组12 V独立模组,经双向LLC谐振变换器并联接入母线,实现充放电控制与故障隔离;结合边缘计算终端开发动态容量模型及并行核容策略。110 kV变电站验证表明:双组并行核容时间缩短90%,故障隔离成功率100%,年均运维成本降低50%,核容报告自动生成准确率100%。该系统通过分组架构与边缘计算协同,实现了蓄电池核容从人工操作向全自动智能在线转型,为智能变电站建设提供关键技术支撑。

Abstract: Targeting the inefficiencies in storage battery capacity verification and large-scale impact of faults in conventional substations, an online capacity verification system based on a grouped parallel architecture and bidirectional LLC (Inductor-Inductor-Capacitor) resonant conversion is proposed. The system reconfigures a 108-cell (2 V each) series battery bank into nine independent 12 V modules, which are then connected in parallel to the DC bus via bidirectional LLC resonant converters to achieve charging and discharging control and fault isolation. A dynamic capacity model and parallel capacity verification strategy are developed in conjunction with edge computing terminals. Validation at a 110 kV substation demonstrates 90% reduction in capacity verification time with dual-group parallel operation, 100% success rate in fault isolation, 50% decrease in annual average operation and maintenance costs, and 100% accuracy in automated capacity verification report generation. By synergizing the grouped architecture with edge computing, this system achieves the transition of storage battery capacity verification from manual operations to fully automated and intelligent online operation, providing critical technical support for smart substation construction.
