【摘要】:电力系统是由发电厂、输电线路、变电站、配电线路和用户计量等设备组成的一个复杂的发供用电系统。变电站是电力系统的枢纽,担负着变换电能电压和分配电能的作用。随着我国经济的快速发展,各个地方对电力的需求也快速增长,特别是在工业聚集区、经济发达地区和人口密集地区尤其明显。而对电力需求大且集中的地区往往也是经济发达地区,土地资源十分宝贵,很难找到一块又方又大的能够建设传统变电站的地方,且传统变电站的建设周期长,有时很难满足这些地区突然增加的负荷需求。因此,急需一种能够快速部署且土地利用率高的新型变电站技术,配送式变电站正是在这种背景下产生的。它灵活的布置方式和快速部署的特点能够满足特殊地区对电力负荷的需求。论文首先介绍了配送式110千伏变电站的特点和建设背景,然后以广阳110千伏变电站为实例,来研究讨论配送式变电站的设计工作。通过计算电网潮流和短路电流,确定一次设备电气参数和二次设备、通信设备的配置方案;并对拟定的两个站址从水文、地质以及交通等情况进行调查分析,经过经济技术比较后确定站址位置;最后,根据前面的分析结果,进行变电站的各部分设计工作,并在论文最后进行了总结和展望。
[Abstract]:Power system is a complex power supply and supply system composed of power plants, transmission lines, substations, distribution lines and user metering devices. The substation is the hub of the power system, which is responsible for changing the power and voltage and distribution of power. With the rapid development of China's economy, the demand for electric power has also increased rapidly in various places. Not in the industrial agglomeration area, the economically developed areas and the densely populated areas are particularly obvious. And the areas with large and concentrated power demand are often also economically developed areas, and land resources are very valuable. It is difficult to find a place where traditional substations can be built, and the construction period of traditional substations is long and sometimes difficult to meet. There is a sudden increase in load demand in these areas. Therefore, a new type of substation technology is urgently needed for rapid deployment and high land utilization. The distribution type substation is produced in this context. Its flexible layout and rapid deployment features can meet the demand for power load in special areas. The paper first introduces distribution. The characteristics and construction background of the type 110 thousand volt substation, and then take the Guangyang 110 thousand volt substation as an example to study and discuss the design of the distribution substation. By calculating the power flow and short circuit current of the power grid, the electrical parameters of the equipment and the two equipment and the configuration of the communication equipment are determined, and the proposed two sites are from hydrology and geology. And the traffic and other conditions are investigated and analyzed, the location of the site is determined after the economic and technical comparison. Finally, according to the results of the previous analysis, the design of various parts of the substation is carried out, and the final summary and Prospect of the paper are also carried out.
