| 摘 要： | 磁暴是源自太阳磁场剧烈变化的地球空间效应，随着电网规模的增大和电压等级的增高，磁暴灾害已经成为诱发电网故障风险的威胁之一.研究电力系统磁暴灾害风险的影响因素可为预防与控制其引发的电网事故提供重要参考.在分析历史典型磁暴事件的基础上，剖析了磁暴诱发电力系统故障的机理，阐述了故障传播与电力系统响应的过程，总结了近年来关于影响电力系统的地磁感应电流水平及其产生的变压器无功损耗方面的研究成果，从磁暴本身的特点和电力系统的参数与结构两方面将影响因素分类.以GIC标准模型，通过改变磁暴扰动环境和电力系统参数，说明了各因素对电网磁暴灾害风险的影响程度，并比较了不同因素影响后果的差异，最后指出了尚未解决的问题和可能的研究方向.

| Abstract: | Geomagnetic storm is the effect on the earth derived from the dramatic changes in the solar magnetic field and has become a severe threat inducing the power failure risk with the increase of the grid size and voltage level. Studying the influencing factors of storm disaster risks on the power system can provide important references for preventing and controlling the accident due to geomagnetic disturbance. On the basis of analyzing the typical power system disaster resulted from geomagnetic storm, firstly, we analyzed the mechanism of storm-induced power system fault and explained how the breakdown transmits and the power system responses,then summarized the researches in recent years about the influence factor of the GIC level and the consequent loss of reactive power, and finally classified these factors according to the intrinsic characteristics of the geomagnetic storm and the topology of power system. We took the GIC benchmark model as an example to indicate the influencing extent of the factors on the power system geomagnetic storm disasters risk by changing the magnetic storm disturbance environment and electrical system parameters, and compared the differences of the different factors. At last, the unresolved issues and possible research directions are proposed. |
