1、 临洪西抽水站电气及微机监控设计临洪西抽水站电气及微机监控设计 摘要 该设计是根据有关资料对临洪西抽水站的电气和微机监控系统设计。首先根据泵站 的规模、特点、运行方式和地区电网情况，及泵站电气负荷的统计计算，主接线方案经 济技术性比较，确定了电气主接线方案。通过计算泵站在各种运行情况下特征点的短路 电流，通过对主电动机的起动计算，选择其起动方式。接着选择主要电气设备包括断路 器、隔离开关、高压熔断器、母线、电流互感器、电压互感器和开关柜等，并对泵站进 行电气设备的总体布置、控制室布置和屋内配电装置。对主电动机、母线和主变压器整 定计算,装设相应的继电保护。而二次部分主要对断路器控制回路、电气测

2、量系统、泵站 中央信号系统、操作电源系统等系统进行了接线设计。还对泵站的变配电设备、高压电 动机和泵房建筑物的防雷措施和接地装置进行了布置。最后通过设计实现了泵站微机测 量、控制和保护。 关键词：泵站；电气设计；电气设备；继电保护；二次接线；微机保护 Abstract The design is based on the information right set of the west pumping station of Linhong， and it is about the electrical parts and computer protection system. First，a

3、ccording to the pump station the size, characteristics, mode of operation, the regional power grid, the statistical calculation of pumping station electrical load and main connection program technical economic comparison ，can identify the main electrical wiring program. Then calculate the short-circ

4、uit current of the various operations, calculate the main motor starter, and choose their starting way. The main electrical equipment is choiced, including circuit breakers, isolation switches, high voltage fuse, busbars, current transformers, voltage transformers and switchgear, etc. Arrange the overall layout of pumping station electrical equipment, the control room layout and distribution equipment inside. Install the corresponding relay to the main motor, bus and main transformer. And the
