Low-impedance generator differential protection is commonly used for detecting stator phase and ground faults in medium-voltage applications. An offshore platform started experiencing sporadic generator differential protection trips during the start-up of a newly commissioned, large water-injection pump (WIP) motor rated at 4,100 kW. The main power sources on the platform are three 16.25-MVA gas turbine generators (GTGs). The GTGs are connected to the 11-kV main electrical distribution system switchgear, which also supplies the low-inrush WIP motor, which is direct-online (DOL)-started.

海上平台上的发电机差动继电器跳闸

低阻抗发电机差动保护通常用于检测中压应用中的定子相位和接地故障。在新调试的额定功率为 4,100 kW 的大型注水泵 (WIP) 电机启动期间,海上平台开始出现偶发的发电机差动保护跳闸。平台上的主要电源是三台 16.25-MVA 燃气轮机发电机 (GTG)。GTG 连接到 11 kV 主配电系统开关设备,该开关设备还为直接在线 (DOL) 启动的低涌流 WIP 电机供电。
