This letter introduces a novel approach to prevent ice formation on transmission lines during ice storms. First, weather forecast is used to calculate minimum currents needed to raise the conductor temperature above the freezing point. Then, a preventive unit commitment model is developed to enforce those minimum limits. Simulation studies are conducted on the three-area RTS-96 system. The results confirm the effectiveness of the developed model in preventing ice formation, through adjustment of generation dispatch and slightly increasing the cost. Limitations of the work are also discussed.

变速箱除冰预防性调度

这封信介绍了一种防止冰暴期间输电线路结冰的新方法。首先，天气预报用于计算将导体温度提高到冰点以上所需的最小电流。然后，开发了一个预防性单位承诺模型来强制执行这些最低限度。对三区域 RTS-96 系统进行了模拟研究。结果证实了所开发模型通过调整发电调度和略微增加成本来防止结冰的有效性。还讨论了工作的局限性。
