论文题目：华润电力登封有限公司电气一二次部分设计
摘 要
工业高速发展的时代，电力是工业的动脉，而发电厂是电力系统的重要组成部分，也直接影响整个电力系统的安全与运行。在发电厂中，一次接线和二次接线都是其电气部分的重要组成部分。
在本次设计中，主要针对了一、二次部分的设计。一次部分对主接线方案的确定、发变组特性及选择到厂用电设备布置的设计做了阐述说明。二次部分则以发变组ECS设计为专题对电气设备逻辑做了深入细致的介绍并简单介绍与过电压保护与避雷设计。
华润登封本期工程规模为1200MW，安装2×660MW超临界燃煤汽轮发电机组并留有扩建的余地。本工程建成后，将成为河南电力系统的主力电厂，对电网的安全经济、稳定可靠运行具有重要作用。
论文根据原始资料，对华润登封电厂电气部分进行设计。发变组控制系统好比是电厂的大脑，稳定的控制系统，对发电机组的安全具有特别重要的意义。为保证机组在正常运行、启动、停机及故障情况下，避免机组及附属设备因厂用电源消失而损坏，提高厂供电的可靠性，经过可靠性、经济性、灵活性的比较，确定了主接线方案，从而确定设备，如变压器、断路器、隔离开关、导线、互感器及防雷设施，此次设计具有可靠性、经济性和实用性。

Abstract
Industry high speed development time, electric power is industrial artery, and the power plant is an important part of power system, but also directly affects the safety and operation of electric power system. In the power plant, a wiring and the two wiring is the important part of the electrical part.
In this design, mainly for the one or two part of the design. A part of the main wiring scheme, generator-transformer group characteristics and selection to the electric power plant equipment layout design was done elaborate description. The two parts is to generator-transformer group ECS design topic of electrical equipment logic to do in-depth and detailed introduction and a brief introduction and over voltage protection and lightning protection design.
China resources Electric power Dengfeng CO., Ltd this project scale of1200MW, mounting2 x660MW supercritical coal-fired turbogenerator and leave expansion. This project is completed, will become the main power plant in China resources Electric power system to power grid safety, economy, stable and reliable operation has an important role in.
According to the original data, the CR Dengfeng power plant electrical part design. Generator transformer group control system is the power of the brain, and stable control system, for generating unit''s safety is of particular importance. In order to ensure units in the normal operation, start, stop and under fault conditions, avoid units and ancillary equipment for power plant with disappear and damage, improve plant power supply reliability, reliability, economy, flexibility through comparison, identified the main wiring scheme, thereby determining device, such as a transformer, circuit breaker, isolating switch, wires, transformer and lightning protection facilities, the design is reliable, economical and practical
