摘　　要：码头电网出现次同步振荡引发电压波动会导致设备故障甚至运营中断。新能源储能抑制装置能够检测系统所需的无功功率,并迅速提供相应大小、相反性质的无功功率,实现系统的动态无功补偿,有效解决码头电网电压震荡问题,保障设备的运行安全和码头作业效率。Sub-synchronous oscillations in port power grids can cause voltage fluctuations,leading to equipment failures and even operational disruptions.New energy storage suppression devices can detect the reactive power required by the system and rapidly provide reactive power of corresponding magnitude and opposite polarity,achieving dynamic reactive power compensation for the system.This effectively resolves voltage oscillation issues in port power grids,ensuring the safe operation of equipment and the efficiency of port operations.
