1. 摘 要
由发电、变电、输电、配电和用电等环节组成的电能生产与消费系统。它的功能是将自然界的一次能源通过发电动力装置转化成电能,再经输、变电系统及配电系统将电能供应到各负荷中心。
电气主接线是发电厂电气设计的首要组成部分,也是构成电力系统的重要环节。主接线的确定对电力系统整体及发电厂本身的运行的可靠性、灵活性和经济性密切相关。并且对电气设备选择、配电装置配置、继电保护和控制方式的拟定有较大的影响。本次设计的供热式火电厂电厂,将从经济性、可靠性以及灵活性几方面予以选择主接线方式、主变压器、短路电流的计算及电气设备的选择,同时将安全性作为继电保护规划、配电装置的规划及防雷规划设计的基本准则,并还须兼顾经济性方面的考虑。
供热式火电厂电气一次部分设计为毕业设计课题,通过本次设计,可以巩固大学所学的专业知识,同时既锻炼了我独立分析和解决电力工程中的设计问题的能力,也为将来的工作和学习奠定了良好的基础。

2. Abstract
The production ofenergy and consumption systems are consisted of ower generation, substation, transmission, distribution and consumption of energy. Its function is to the natural world through the power of the primary energy into electrical energy power plant, then the substation and distribution system will supply electricity to the load center.
Electrical wiring is the main electrical power plant component of the primary design, but also constitute an important part of the power system. Determination of the main cable on the power system and power plant itself, the overall operation of the reliability, flexibility and economy are closely related. And choice of electrical equipment, power distribution device configuration, relay protection and control of the formulation has a greater impact. The design of the heating-type thermal power plant power plants, from the economy, reliability and flexibility to select the main aspects of connection mode, the main transformer, short-circuit current calculation and selection of electrical equipment, as well as the safety relay protection planning, distribution planning and lightning protection devices of the basic criteria for planning and design, and must take into account economic considerations.
Heating-power power plant is designed to graduate the first part of the design issues, through the design, can be learned by the consolidation of the University of expertise, both at the same time exercise my independent analysis and solution of electrical engineering design problems, but also for the future work and study has laid a good foundation.
