Abstract


Stand-alone unit with large domestic power plants were constructed , capacity and excitation capacity is increasing , especially in domestic Three Gorges Hydropower Plant 26 single 700MW hydroelectric generating successively put into operation a new de-excitation of the excitation system technology scientific and technological problems . We must have a large enough the deexcitation capacity , and also to have the shortest possible the deexcitation time , this is currently placed in the problems of of all hydropower technology workers before . The papers from engineering practice , the no-load running of large units with three-phase short , how to estimate a system's the deexcitation capacity , theoretically analyzed in detail , and pushed to the now ABB company for Three Gorges Left Bank Hydropower Plant hydraulic generator parameters , for example , made ??a practical engineering examples , can be seen from the example , the set computing theory has a strong practical value ; paper on the use of ZnO pressed the issue of how to shorten the time of deexcitation sensitive resistors as the deexcitation material can significantly shorten the time of deexcitation 's controversial view . Theoretically , itemized analysis ZnO electrical characteristics of ZnO and SiC on how to shorten the deexcitation time the actual engineering simulation can be seen from the simulation results with the simulation curve , ZnO is ideal deexcitation material the deexcitation time almost close to the ideal situation . How safe and reliable final thesis on the the large unit deexcitation system appear in the actual project failure , made ??a detailed analysis summary of the magnetic system on the the unreasonable technical issues have designed , made ??the corresponding improvement , which is a large unit off the operation made ??the theoretical analysis .
