2X300MW火力发电厂第一期工程电气部分初步设计 计算说明书（论文）+任务书+开题报告+小论文+CAD图纸
中 文 摘 要
随着时间的推移，社会的进步，人们的生活水平日益提高，人们对周围设施的要求意识也逐渐提高起来。本设计是2X300MW凝气式发电厂电气部分的初步设计。综观世界电力系统发展的趋势，本设计中的电厂容量并不算大，但这种中小型电厂对于沿海地区及一些偏僻落后地区的供电仍有明显的帮助。
在本设计中通过对任务书的详细分析，并根据设计规程手册中的要求，首先确定了发电厂的变压器容量，并通过比较选择了主接线的形式。在进行完短路计算后，根据计算结果选择了设计中所需的各种器件，并进行了校验。通过所学的课本中的知识和翻阅资料确定了本设计中发电厂的配电系统，自动装置及继电保护系统。最后根据配电系统画出本设计中的主接线图，断面图和平面图，并根据所查尺寸设计出防雷保护，画出防雷保护设计图纸最终完成本次设计。

Abstract
Along with time passing, society's progress, people's living standard enhances day by day, the people also gradually enhance to the periphery facility request consciousness. This design is 2X300MW congeals is mad the type power plant electricity partial preliminary designs. Comprehensive survey world electrical power system development tendency.
In this design power plant capacity does not calculate in a big way, but this kind of middle and small scale power plant still had the obvious help regarding the coastal area and some remote back wardness areas power supplies. In this design through to project description multi an alysis, And the basis designs in the regulations handbook the request, first has determined the power plant transformer capacity, and has chosen the host wiring form through the comparison. After carries on short-circuits the computation, has chosen each kind of component according to the computed result which in the design needs, and has carried on the verification. Through in the textbook knowledge which studies and glances through the material to determine in this design the power plant electrical power distribution system, automatic device and relay protection system. Finally draws in this design according to the electrical power distribution system the main wiring diagram, sectional drawing and horizontal plan, and the basis looks up the size to design the anti-radar protection, draws the anti-radar protection design paper to be final a cost design.
Key words: power plant, transformer, automatic device, relay protection, anti-radar protection
