摘　　要：本研究量化了变电站接地电位升高与输电极接地电位升高的关系,以帮助设计师根据极接地电位上升量来计算变电站接地电位上升,以确保输电线路接地系统在变电站故障情况下始终满足安全标准。通过实例验证了通过测量极接地电位升高来估算变电站接地电位升高的方法。This paper quantifies the relationship between the rise of the ground potential of the substation and the rise of the ground potential of the transmission electrode,to help the designer to calculate the rise of the ground potential of the substation according to the rise of the pole ground potential,and to ensure that the grounding system of the transmission line always meets the safety standards in the event of a substation fault.Finally,an example is used to verify the method of estimating the rise of the ground potential of the substation by measuring the rise of the pole ground potential.
