Alternative Methods for Testing the Pole-to-ground Insulation of Thyristor Valves in Uhvdc Systems
In the design of DC system, more than one MVU tower may be used between pole-to-neutral voltages. This is especially common for UHVDC systems. The insulation design of these MVU’s need to be verified by dielectric type tests as specified by international standards. However, the application of several MVU’s in series makes the test set-up complicated. One straightforward solution is to install a...
متن کاملExternal Insulation Design of Converter Stations for Xiangjiaba - Shanghai ± 800 kV UHVDC Project
-External insulation is one of the critical aspects in the HVDC equipments and converter station design. Especially for UHVDC converter stations, the long creepage and clearance required has significant impact on the equipment and station design. The external insulation design of DC yard, valve hall, and for converter valves is presented. It is the intention of this report to review and summari...
متن کاملElectrostatic Field Analysis of 1200 Kv Testing Transformer by Boundary Element Method
Design of a 1200 kV power transformer is a real challenge for designer from dielectric point of view. It is possible to design a more compact transformer meeting even higher insulation levels with lesser insulation content. This has been possible with the introduction of sophisticated Computer-Aided Electrostatic Field Analysis. Analysis of the Lead Exit assembly of 1200 kV HV is presented. Two...
متن کاملislanding detection methods for microgrids
امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولUsing PCR and culture methods for Mycoplasma testing
Mycoplasma contaminants can be considered important not only for their roles as pathogens but also they may indicate that insufficient care has been taken during vaccine manufacture or quality control. The purpose of this study was to test the poliomyelitis vaccines for Mycoplasma by culture and polymerase chain reaction (PCR) methods. During 2008 to 2009, a total of 47 lots of oral poliomyelit...
