Pub Date :2004-10-01 Pages: 650 Publisher: China Electric Power Press title: power system electrical equipment selection and practical calculation of the original price: 63.00 yuan Author:… the Fu Zhi Lan compiled Press: China Electric Power Press Publication Date: 2004-10-1ISBN: 9.787.508.323.220 Words: 941.000 yds: 650 Revision: 1 Binding: Paperback: Editor's Summary This book is based on the relevant national standards. industry standards. and professional documents collected in recent years. and this direction Chinese and foreign information and compiled from the combination of a wealth of practical experience. The book is set in accordance with the classification of the power equipment chapter. the book is divided into 12 chapters. including practical calculation of short-circuit current. electrical equipment selection and checking transmission lines. substation bus parameters calculated instance. enclosed bus. neutral grounding device selection. compensation devices. electromagnetic parameters and the temperature rise of the turbine generator. asynchronous motor electromagnetic parameters and electromagnetic parameters and failure analysis of transformer insulation of high-voltage circuit breakers. breaking with the closing of the isolation switch. power engineering with sealed maintenance-free lead-acid battery technology data capacity. Each chapter has a calculation example. provided data and calculation methods are practical and accurate principle. The book is available for reference use in power system design. grid scheduling with running. power equipment operation and maintenance. and other professional engineering and technical personnel. and also can be used as a practical reference for universities and students. Practical calculation of short-circuit current of Contents Preface Chapter first short-circuit current of the purposes of the calculation. the non-periodic component of the three-phase short-circuit current assumptions and calculation steps Section II of the network simplifies the fourth quarter and the equivalent the Section III three-phase short-circuit current cycle component Section VI Section V three-phase short circuit current impact of current and full current of short-circuit current section VII of the thermal effects of asymmetric short-circuit current calculation section VIII of the asynchronous motor feedback current section IX of the three-phase short-circuit current instance selection of electrical equipment and checking Section 6 of Section 5 bare conductor of the first section turbogenerator select second transformer capacity to choose the general provisions of Section III power plant electrical the main wiring the fourth quarter mentor and electrical equipment selection power cable section VII. section X of the high-pressure high-voltage circuit breaker Section VIII pressure isolation switch section IX. SF6 enclosed electric fuses Section XI of current limiting reactors Section XII the voltage of section 13 of the current transformer transformer section XIV of insulators and wall bushing section XV. equipment selection and checking instance Chapter transmission lines. substation bus parameters calculated with the instance of the first section of transmission line parameters calculated Section 2 Transmission Line frequency parameters Measurement Section III transmission line substation bus parameters calculated the lightning overvoltages use parameters in section IV Section 5 Chapter flowing through the the substation grounding device into the short-circuit current estimates enclosed bus the first section of the whole company from closed the busbar section II. the whole company away from the fixed value of the phase enclosed bus and main technical requirements the third quarter closed bus parity Section IV 200MW. 300MW and 600MW generator main enclosed bus (self-cooled) checksum.
