【摘要】：配电规划是根据某一地区今后用电负荷发展的预测,同时根据地理环境、电源布局等条件,对该地区的配电系统作出的规划。配电规划的质量直接影响供电可靠性。港口作为城市发展的重要枢纽,在城市经济建设中发挥重要的作用。随着港口的快速发展,港口设备也向着大型化、自动化、多样化发展,尤其是危险品类港口,由于其设备和供电需求的特殊性,对配电规划工作提出了更高的要求。本文针对某新建的石化码头的用电负荷及其今后发展的预测,做出与之相适应的配电规划研究工作。本文的主要工作如下:1.介绍本论文所研究的石化码头的概况,详细阐述了主要用电负荷的资料和其在码头的分布情况。2.在需要系数法与统计综合法的技术理论基础上,分别对主要用电负荷进行了负荷预测研究。从保证供电可靠性的角度出发,选取最优解作为负荷预测的结果。对变电所的选址进行了规划,依据电压损失的技术理论,对单变电所方案进行评估,并提出解决方案。3.依据国家标准及变电所建设理论,对变电所内部变压器、高、低压系统等进行规划研究。并以单个泊位为例,对码头前沿用电负荷进行配电规划。4.阐述了本论文涉及的一级负荷概况,以负荷预测的结果作为依据,提出了以柴油发电机作为备用电源的规划方案。在供电可靠性评估的理论基础上,对此方案进行了供电可靠性分析,并论证了该方案对一级负荷的供电可靠性的影响。
[Abstract]:Distribution planning is based on the forecast of the future power load development in a certain area and the planning of the distribution system in that area according to the conditions of geographical environment and power supply distribution. The quality of distribution planning directly affects the reliability of power supply. As an important hub of urban development, port plays an important role in urban economic construction. With the rapid development of the port, the port equipment is developing towards the large-scale, automation and diversification, especially for the dangerous goods port. Because of the particularity of its equipment and power supply demand, the power distribution planning work has put forward higher requirements. According to the load of a new petrochemical wharf and the forecast of its development in the future, this paper makes the research work of distribution planning corresponding to it. The main work of this paper is as follows: 1. The general situation of petrochemical wharf studied in this paper is introduced. The data of main electric load and its distribution in wharf are described in detail. Based on the technical theory of the demand coefficient method and the statistical comprehensive method, the load forecasting of the main electric load is studied separately. In order to ensure the reliability of power supply, the optimal solution is selected as the result of load forecasting. The location of substation is planned. According to the technical theory of voltage loss, the scheme of single substation is evaluated, and the solution is put forward. According to the national standard and the theory of substation construction, the internal transformer, high and low voltage system of substation are planned and studied. Taking a single berth as an example, the distribution planning. 4. 4. Based on the results of load forecasting, the planning scheme of diesel generator as backup power supply is put forward. Based on the theory of power supply reliability evaluation, the power supply reliability of this scheme is analyzed, and the influence of this scheme on the power supply reliability of first class load is demonstrated.
