摘　　要：不同型号发电机的并网有助于提升设备的使用率,纾解矿山项目基建施工期电网容量小、大功率设备启动困难的用电难点。通过充分考虑技术经济可行性,结合工程实例,探索出将不同电压等级、接地形式和容量的柴油发电机并网的技术路径。通过增加升压变压器、装设专用接地变等技术手段,实现低压与高压发电机电压一致、接地方式一致,从而满足并网的先决条件。The grid connection of different types of generators helps to improve the utilization rate of equipment and relieve the power consumption difficulties of small power grid capacity and difficult start-up of high-power equipment during the construction period of mine project infrastructure.By fully considering the technical and economic feasibility,combined with engineering examples,the technical path of grid con nection of diesel generators with different voltage levels,grounding forms and capacities is explored.By add ing step-up transformers and installing special grounding transformers,the voltage and grounding mode of low-voltage and high-voltage generators are consistent,so as to meet the prerequisites for grid connection.
