摘　　要：大化水电站开关站迁移改造后,原有继电保护配置方案的外部条件改变,处于规范要求的边缘,存在不满足技术要求的可能性。为了适应该项目的建设,笔者对原方案是否满足技术要求和新方案的适用性进行了分析,通过详细计算,综合考虑项目建设的因素,从技术经济方面对2个继电保护配置方案进行比较,得出原方案可以满足技术要求,该项目可以维持采用原方案的结论。After the migration and transformation of the switch station of Dahua Hydropower Station, the external conditions of the original relay protection configuration scheme change, which is on the edge of the specification requirements, and there is a possibility that it does not meet the technical requirements. In order to adapt to the construction of the project, the author analyzes whether the original scheme meets the technical requirements and the applicability of the new scheme. Through detailed calculation, considering the factors of project construction, the two relay protection configuration schemes are compared from the technical and economic aspects. It is concluded that the original scheme can meet the technical requirements and the project can maintain the original scheme.
