摘要水泥厂余热电站发电机与水泥厂配电网并网运行，余热电站发电机中性点接地方式要与水泥生产线配电网匹配，满足接地电流允许值要求。依据国内发电机接地故障电流允许值要求，对发电机中性点不接地方式（即经避雷器接地）和经消弧线圈接地方式进行了分析、计算。通过算例阐述了国内水泥厂余热电站发电机中性点接地方式的选择和计算方法。

Abstract: The waste heat recovery power station generator of cement plant is connected with the electrical distribution network of cement plant. The neutral grounding mode of waste heat recovery power station generator needs to be matched with the electrical distribution network of cement plant, to meet the requirements of grounding current. According to the domestic standard allowable value of grounding current of generator fault, the non-grounding mode of generator neutral point (i.e., grounding by lightning arrester) and grounding by arc suppression coil are analyzed and calculated. The selection and calculation method of neutral grounding mode of waste heat recovery power station generator in cement plant are illustrated by examples.

Key words: neutral point ground mode arc suppression coil waste heat recovery power station
