摘要
构网型变流器凭借自身独特的运行优势,不仅能够以逆变器模式在弱电网正常运行时实现电力的双向高效流动,而且在弱电网遭遇故障或异常状况时,可以迅速切换至整流器模式,有效吸收过电压、过电流等故障信号,从而显著提升电力系统的稳定性与安全性,这种灵活的双模式切换能力使其在提升电网整体性能方面具有不可替代的价值。文章以构网型储能变流器的工作原理和结构特点为切入点,分析了其对弱电网电压的具体控制策略和优化策略,以期为相关人员的具体实践工作提供有效参考。
Grid type inverters,with their unique operational advantages,can not only achieve efficient bidirectional power flow in inverter mode during normal operation of weak grids,but also quickly switch to rectifier mode when weak grids encounter faults or abnormal conditions,effectively absorbing fault signals such as overvoltage and overcurrent,thereby significantly improving the stability and safety of power systems.This flexible dual-mode switching capability makes it irreplaceable in improving the overall performance of the power grid.The article takes the working principle and structural characteristics of grid type energy storage inverters as the starting point,and deeply analyzes specific control and optimization strategies,in order to provide effective reference for relevant personnel’s practical work.
