摘　　要：随着油田智能配网的不断发展,因切换网络重构方式而导致继电保护定值频繁改变的问题日益凸显。另外,油田配网感应电机负荷众多,负荷电磁暂态特性对网络保护的影响也亟待研究。针对上述问题,仿真分析了感应电机故障暂态电流特点。提出一种油田智能配网不同重构方式统一定值保护方案,建立某油田智能配网模型。通过仿真与整定计算,验证该方案的正确性。With the development of the oilfield smart distribution grid, the problem of frequent change of the relay protection setting caused by switching network reconfiguration mode becomes increasingly prominent. In addition, as induction motor loads are numerous in the oil field, effects of the electromagnetic transient characteristics of the induction motor loads on network protection need to be studied urgently. Aiming at solving these problems, this paper firstly simulates and analyzes the characteristics of the induction motor fault transient current, and then proposes a kind of unified value protection scheme under different reconstruction methods in oilfield smart distribution grid. Finally, it establishes the model of an oilfield smart distribution network and verifies correctness of the pro- posed scheme by simulation and setting calculation.
