【摘要】：通过对具体的电力系统进行分析计算,我们可以了解到其各个配置是如何起到保护系统的作用,由此可以得到一个定值,在这个定值以内工作即可达到保护装置的系统运行要求,这就叫做继电保护的整定计算。整定计算在继电保护工作中起到十分重要的作用。通过精细的整定计算,系统中的每个保护装置才能在一起安全地进行工作。本文根据所要设计的110kV变电站的电力负荷资料,按照有关规定和规范,对110kV变电站进行继电保护的配置和整定计算,包括主接线设计和继电保护的配置,短路电流计算以及继电保护装置的选型等。设计中首先根据变电站的资料,通过进行技术比较和经济比较对变压器进行选型,进而确定110kV电气主接线图,其次分别在最大运行方式下和最小运行方式下进行了短路电流计算,对变压器和线路也分别进行继电保护配置设计。
[Abstract]:Through the analysis and calculation of the specific power system, we can understand how each configuration plays the role of protecting the system, and thus we can get a certain value. The system operation requirement of the protective device can be achieved by working within this fixed value, which is called the setting calculation of the relay protection. Setting calculation plays an important role in relay protection. Each protection device in the system can work safely together by careful setting calculation. According to the power load data of the 110kV substation to be designed, the configuration and setting calculation of the relay protection for the 110kV substation are carried out according to the relevant regulations and specifications, including the main wiring design and the configuration of the relay protection. Short-circuit current calculation and relay protection device selection and so on. In the design, according to the data of substation, the transformer is selected by technical comparison and economic comparison, and then the main wiring diagram of 110kV is determined. Secondly, the short-circuit current is calculated under the maximum operation mode and the minimum operation mode, and the relay protection configuration is designed for the transformer and the line respectively.
