多台分散独立供电柴油发电机组并网改造

为解决广西水电工程局安哥拉公司巴亚营地建设初期采用近20多台柴油发电机组分散独立供电带来的高污染、高能耗、高成本问题，提出了三种柴油发电机组并网发电改造方案并进行运行成本分析比较，结合库存材料情况，选择了较优的集中并网发电方案，并运用负荷中心算法和结合实际选定了中心发电房位置。实施改造及并网发电后，营地发电成本降低37%，并为日后引入市电做好准备。

On-grid Transformation of Multiple Scattered Independent Power Supply Diesel Generators

In order to solve high pollution, high energy consumption and high cost problems caused by about 20 diesel generators ,which were introduced during the initial construction period,at Puerto camp of Guangxi Hy-dropower Engineering Bureau-Angola Company, three kinds of on-grid transformation schemes for these diesel gen-erators were proposed. The optimal integrated on-grid scheme was selected based on the materials in stock, and the location of central powerhouse was determined by using of load center algorithm based on the actual situation. The generation cost at the camp decreases 37%after the on-grid transformation, which is ready for connecting to the main electric supply system in the future.
