电气工程及其自动化专业毕业设计

摘要：发电厂电气一次部分设计内容主要包括发电厂电气主接线的设计，发电

厂电气系统主要电气设备的选择及其短路电流计算。

本设计针对发电厂电气部分设计中的重中之重——发电厂电气主接线设计做了重点阐述，其中包括电气主接线的基本要求、基本设计原则，电气主接线形式的分类，发电厂主变压器的选择设计以及发电厂电气主接线图的设计、绘制等。然后谈到了发电厂主要电气设备的选择以及为其选择设计做准备的短路电流计算。为了发电厂的正常运行还要对电气设备的校验，并且对防雷保护做了规划。最终做到了充分的考虑和精心的设计，保证了该电厂能够可靠、灵活、经济的运行。

design content of the main electrical wiring, including power plants in the design, the main electrical power plant equipment electrical system and the choice of short-circuit current calculation.

Electric power plants are designed for some of the most important tasks - the main electrical power plant wiring done a focus on design, including the electrical wiring of the main basic requirements, the basic design principles, electrical wiring the main form of classification, the main power plant transformer design and the choice of main electric power plant wiring diagram of the design, drawing, and so on. And then talked about the main electrical power plant equipment and the choice of design for their choice to prepare for the short-circuit current calculation. The electrical equipment should be checked to the normal operation of power plants, and the protection of mine should be planned. Eventually fully and carefully consider the design to ensure that the plant can be reliable, flexible and economic operation.
