電力系統(tǒng)分析與設(shè)計

前言

　　很高興能再次為《電力系統(tǒng)分析與設(shè)計（英文改編版·原書第4版）》一書作序。本書第3版于2002年出版，于2004年在中國影印發(fā)行，受到了國內(nèi)外電力系統(tǒng)分析設(shè)計領(lǐng)域工程技術(shù)人員和高校師生的廣泛關(guān)注。這次在中國出版的第4版比第3版做了部分改動，使本書更加實用。本書主要介紹電力系統(tǒng)分析和設(shè)計的方法，并借助先進的電網(wǎng)可視化分析軟件，幫助學生深入理解電力系統(tǒng)的基本理論和分析方法?！　”緯闹饕攸c如下：　　1.對于電氣工程專業(yè)的大學生來說，本書內(nèi)容十分全面，這是美國教材不同于我國教材之處，對于本書的內(nèi)容，國內(nèi)一般是分成幾本教材來講述的。類似的教材，如《電力系統(tǒng)分析》、《電力系統(tǒng)》、《電能系統(tǒng)基礎(chǔ)》等，所涵蓋的知識點都沒有本書全面?！　?.編寫內(nèi)容新。本書是2008年出版的最新版，內(nèi)容反映了電力系統(tǒng)領(lǐng)域內(nèi)的最新問題和研究成果，包括電力市場環(huán)境下電力系統(tǒng)的一些問題。

《電力系統(tǒng)分析與設(shè)計（第4版）》由于知識點全面、系統(tǒng)，理論與工程實際聯(lián)系緊密，實用性強，在國內(nèi)外讀者中廣受贊譽，而成為電力系統(tǒng)分析設(shè)計領(lǐng)域的重要參考資料。    原書是基于美國國情而編寫的高等學校教學用書，為了使該書的內(nèi)容更為適用于廣大的中國讀者，應機械工業(yè)出版社之邀，編者在承擔本書中文版翻譯工作的同時，在綜合考慮知識內(nèi)容的適用性、連貫性和行文簡潔的基礎(chǔ)上，對原書內(nèi)容、結(jié)構(gòu)做了一些調(diào)整，形成了本英文改編版。    改編版相對原書作了如下調(diào)整：原書每章均包括“案例分析”和正文（包含“習題”和“課程設(shè)計”）兩個部分。改編版為保證全書的完整性，保持原書正文內(nèi)容不變，但從中國讀者的應用角度出發(fā)，去掉了原書各章的“案例分析”部分。同時，從刪除的“案例分析”中精選了10篇對國內(nèi)讀者較具代表性和借鑒意義的論文，組織在一起新增了第14章（Extended），為開闊讀者視野提供一個窗口，以使廣大讀者了解電力系統(tǒng)發(fā)展現(xiàn)狀及未來新方向。內(nèi)容涉及分布式發(fā)電、可視化電網(wǎng)、廣域安穩(wěn)控制系統(tǒng)、動態(tài)安全評估等電力系統(tǒng)前沿領(lǐng)域。    改編版的出版，是將外文教材引入、消化，使之適合中國讀者的一次有益的嘗試。原書內(nèi)容經(jīng)過調(diào)整后將更好地體現(xiàn)“實用性強、應用性強”的特點。期望本書能夠成為國內(nèi)電力系統(tǒng)專業(yè)教師、學生的優(yōu)秀參考教材。

章節(jié)摘錄

　　HISTORY OF ELECTRIC POWER SYSTEMS　　In 1878， Thomas A. Edison began work on the electric light and formulated the concept of a centrally located power station with distributed lighting serving a surrounding area. He perfected his light by October 1879, and the opening of his historic Pearl Street Station in New York City on September 4, 1882, marked the beginning of the electric utility industry （see Figure 1.1）. At Pearl Street, dc generators, then called dynamos, were driven by steam engines to supply an initial load of 30 kW for 110-V incandescent lighting to 59 customers in a I-square-mile area. From this beginning in 1882 through 1972, the electric utility industry grew at a remarkable pace——a growth basedon continuous reductions in the price of electricity due primarily to techno logical acomplishment and creative engineering.　　The introduction of the practical dc motor by Sprague Electric, as well as the growth of incandescent lighting, promoted the expansion of Edisons dc systems. The development of three-wire 220-V dc systems allowed load to increase somewhat, but as transmission distances and loads continued to increase, voltage problems were encountered. These limitatious of maximum distance and load were overcome in 1885 by William Stanleys development of a commercially practical transformer. Stanley installed an ac distribution system in Great Barrington, Massachusetts, to supply 150 lamps. With the transformer, the ability to transmit power at high voltage with corresponding lower current and lower line-voltage drops made ac more attractive than de. The first single-phase ac line in the United States operated in 1889 in Oregon, between Oregon City and Portland 21 km at 4 kV.
