1. 摘 要
由發(fā)電、變電、輸電、配電和用電等環(huán)節(jié)組成的電能生產(chǎn)與消費系統(tǒng)。它的功能是將自然界的一次能源通過發(fā)電動力裝置轉(zhuǎn)化成電能，再經(jīng)輸、變電系統(tǒng)及配電系統(tǒng)將電能供應(yīng)到各負荷中心。
電氣主接線是發(fā)電廠電氣設(shè)計的首要組成部分，也是構(gòu)成電力系統(tǒng)的重要環(huán)節(jié)。主接線的確定對電力系統(tǒng)整體及發(fā)電廠本身的運行的可靠性、靈活性和經(jīng)濟性密切相關(guān)。并且對電氣設(shè)備選擇、配電裝置配置、繼電保護和控制方式的擬定有較大的影響。本次設(shè)計的供熱式火電廠電廠，將從經(jīng)濟性、可靠性以及靈活性幾方面予以選擇主接線方式、主變壓器、短路電流的計算及電氣設(shè)備的選擇，同時將安全性作為繼電保護規(guī)劃、配電裝置的規(guī)劃及防雷規(guī)劃設(shè)計的基本準則，并還須兼顧經(jīng)濟性方面的考慮。
供熱式火電廠電氣一次部分設(shè)計為畢業(yè)設(shè)計課題，通過本次設(shè)計，可以鞏固大學(xué)所學(xué)的專業(yè)知識，同時既鍛煉了我獨立分析和解決電力工程中的設(shè)計問題的能力，也為將來的工作和學(xué)習(xí)奠定了良好的基礎(chǔ)。

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.

Key words heating-power plant the electricity lord connects line the calculation of short-circuit current selection and check of equipment
