System Nominal Voltage

In this paper, the application of a series grid-side converter (SEGSC) connected to a wind-turbine-driven doubly fed induction generator (DFIG) is introduced. The setup allows the wind turbine system an uninterruptible fault ride-through of voltage dips. The SEGSC can compensate the faulty line voltage, while the DFIG wind turbine can continue its nominal operation as demanded in actual grid codes.

This publication deals primarily with small and medium-sized induction motors which are the most common type of alternating current motor. The combination of new materials and more sophisticated methods for calculation, design and production have made the modern three-phase induction motor a robust and reliable prime mover.

The City of Naperville operates a Department of Public Utilities, which includes a municipal electric utility. Naperville’s electrical distribution system is nearly 90% underground, except in older areas of town where overhead facilities are still utilized. The nominal voltage of the system is 12.47kV transformed from 34.5kV and 138kV. There are 6 points of service on the 138kV transmission system from bulk power providerComEd. The City does not have generation capability at this time.
