【摘要】：电网规划是电力系统规划的重要组成部分,其任务是根据规划期间的负荷增长及电源规划方案确定相应的最佳规划结构,以满足经济可靠地传输电力的要求。因此做好电力工程建设的前期规划工作,落实本体工程的建设条件,协调其建设进度,优化其设计方案,其意义尤为重大。本课题根据春风采油厂排601区块近五年的产能规划及负荷发展概况,分别从带载能力、供电可靠性等方面对其供电电源35kV春风变电站的运行现状进行深入分析,进而阐述了春风变电站升压扩建的必要性;结合现场实际,设计完成春风变电站升压扩建总体方案,然后根据总体设计方案,选取110kV供电电源点,确定主变容量,完成断路器、隔离开关、电流互感器等重要一次设备的选型;在此基础上对主变和线路进行保护配置研究,并针对所选主变、线路保护设备原理特性,选择相应算法对系统进行定值整定。此外,本文还对现场综合自动化系统的相关配置进行了施工方案设计,实现对主要设备的自动监视、测量、控制、保护以及远动信息传递,提高全站的安全运行水平。论文结合工程实践,对春风变电站升压扩建工程中设备选型和保护配置等实际应用问题展开了深入研究,课题具有一定的普遍性和实践性。
[Abstract]:Power network planning is an important part of power system planning. Its task is to determine the optimal planning structure according to the load growth and power planning scheme during the planning period in order to meet the requirements of economic and reliable transmission of power. Therefore, it is of great significance to do well the preliminary planning of electric power engineering construction, to implement the construction conditions of ontology engineering, to coordinate its construction progress and to optimize its design scheme. According to the production capacity planning and load development of Block 601 in Chunfeng Oil production Plant in recent five years, the operation status of its power supply 35kV Chunfeng Substation is analyzed from the aspects of load capacity, power supply reliability and so on. Then it expounds the necessity of the booster expansion of the Chunfeng substation, designs and completes the overall scheme of the booster expansion of the Chunfeng substation, then selects the power supply point of 110kV according to the overall design scheme, determines the main transformer capacity, and completes the circuit breaker. The main transformer and line protection configuration are studied on this basis, and the corresponding algorithm is selected to set the value of the system according to the selected main transformer and the principle characteristics of the line protection equipment. In addition, the related configuration of the field integrated automation system is designed to realize the automatic monitoring, measurement, control, protection and telecontrol information transmission of the main equipment, so as to improve the safe operation level of the whole station. Combined with engineering practice, the paper deeply studies the practical application problems such as equipment selection and protection configuration in the booster expansion project of Chunfeng substation, and the subject has certain universality and practicality.
