I220kV 电网输电线路继电保护与自动装置的设计摘 要电力在现代生产生活中是必不可少的，没有电能社会生活和生产不能正常进行。鉴于电能对社会发展的重要作用，维护电能显得格外重要，继电保护则是电力系统能否正常工作的关键所在。继电保护可以保证电力系统的正常运转，也可以迅速排除故障部分，保证无故障部分迅速恢复工作；不仅确保了社会生活和经济的正常运转，还可以维护人们生命财产的安全。本设计对 220kV 电网进行了继电保护和自动装置整定计算，包括对电气主接线设计及主要电气设备的选择、系统运行方式的制定和变压器中性接地点的选择系统、最大负荷的潮流分布继电保护装置的整定计算及校验,根据本电网的特点和运行要求，在满足继电保护“四性”要求的前提下，求得最佳方案，分别配置了零序、距离、高频以及横差保护，最后对全套保护进行了评价。关键词：继电保护；220kV；整定计算IIDesign Of Relay Protection And Automatic Device For 220kV Transmission LineABSTRACTElectric power is essential in modern production and life. Without electric energy, social life and production can not be carried out normally. In view of the important role of electric energy in social development, the maintenance of electric energy is particularly important, and relay protection is the key to the normal operation of the power system. Relay protection can ensure the normal operation of the power system, can also quickly remove the fault part, and ensure the rapid recovery of the fault free part; not only ensure the normal operation of social life and economy, but also maintain the safety of people's lives and properties. In this design, the setting calculation of relay protection and automatic device for 220kV power grid is carried out, including the design of main electrical connection, the selection of main electrical equipment, the formulation of system operation mode, the selection of neutral grounding point of transformer, the setting calculation and verification of th...
