摘要
本設(shè)計主要是針對焦作電廠的110kV一次系統(tǒng)，概述了焦作電廠設(shè)計的基本過程和基本方法。第一章概括介紹了國內(nèi)外電力工業(yè)的研究及發(fā)展現(xiàn)狀和焦作電廠的基本情況，為后幾章提供所需的基本資料。第二章是電氣主接線和電氣設(shè)備的選擇，根據(jù)焦作電廠的原始資料擬定了主接線方案，確定發(fā)電機、主變壓器、高壓廠用變壓器和高備變壓器的容量和型號。發(fā)電廠電氣主接線是發(fā)電廠電氣設(shè)計的主體，與電廠運行的可靠性、經(jīng)濟性要求等密切相關(guān)，對電器選擇和布置，繼電保護和控制方式等都有較大的影響。第三章對焦作電廠一次系統(tǒng)做了短路電流計算，為后面設(shè)備的選型提供了依據(jù)。第四章是一次系統(tǒng)電器設(shè)備的選擇，并在正常工作條件下和短路條件下對其進行校驗。第五章是針對配電裝置的設(shè)計，同時也是對前幾章內(nèi)容的綜合概括。
隨著國民經(jīng)濟和科學(xué)技術(shù)的發(fā)展，發(fā)電機單機容量在不斷擴大，這就對電廠的主接線形式和配套設(shè)備提出了更高的要求，同時也要求發(fā)電廠做到可靠、經(jīng)濟、合理地運行，滿足人們對電能的基本需求。

Summary
This design is to aim at making one subsystem of Jiao Zuo power station 110 kV mainly.Chapter 1 has generalized to introduce research of domestic and international electric power industry and present conditions and basic circumstance of Jiao Zuo power station that is basic data needed by several chapters later . Chapter 1 is a choice that connects line and the electricity equipments.According to the original data of Jiao Zuo power station to draft connect line form, capacities andt model numbers of generators, main transformers,the transformer the high pressure used by an factories, high the capacity transformers used in case.Connects the line is body of designs the power plant,.Credibility and economy standard of power station is closely related,it has bigger influence to choice and arrangement of the electric appliances, to the way of protection and control, etc.According to the technique data of chapter 2, do the short-circuit electric current calculation of subsystem in chapter 3, provides basises for the behind equipments. The choice of the subsystem in Chapter 4, it's carry on check electric of appliances equipments under the condition of normal hort-circuit condition. Chapter 5 is aim to the design of the配電裝置

Also is the synthesization of before part.
Along with the development of science and technology, single machine capacity of generator is extending continuously,it needs higher requests to connected the line form and the kit equipmentses of the power station, also request the power plant to attain the credibility, economy, reasonable movement, also satisfy the people's basic need that is the electric power.
Keywords：the subsystem，forms of main connected lines, short-circuit calculation，electricity equipments.
