Project Title: High-Voltage Equipment Design Tool
SkyBlue Research, Delmar, NY
BACKGROUND
In all but the smallest power plants, generators produce electric power
between 13.8 and 28 kV. It is then "stepped up" with a generator
step-up transformer (GSU) to transmission voltages ranging from 69 kV
to 765 kV. Estimates are that the GSU contributes as much as 0.5% to
2% of the overall generating plant efficiency losses. These losses can
be eliminated with generators designed to operate at transmission voltages.
In order to design such high-voltage generators, a design tool is required
to calculate and predict electric and magnetic fields inside the complicated
generator geometry.
OBJECTIVE
The project objective is to develop a computer software package that
will enable the calculation of high-voltage electric and magnetic fields
in equipment with complex geometries.
DESCRIPTION
SkyBlue Research will work together in developing a three-dimensional
electromagnetic analysis software for designing high-voltage generators
and other electrical equipment. The analysis software will enable designers
to ensure that electric fields remain below critical levels in coil
insulation and the surrounding space. The software will analyze fields
in three dimensions in the presence of materials with non-linear electrical
properties or complex geometries. The analysis will account for resistive,
capacitive, and inductive effects.
BENEFITS
High-voltage generators can improve electric generation efficiency by
an estimated 0.5 - 2%, with a concomitant reduction in emissions. The
availability of this high voltage design tool will help electrical equipment
manufacturers design generators that are competitive on the world market,
and retain jobs in New York State. High-voltage generators will reduce
the cost of electricity to consumers.
SCHEDULE AND STATUS
In addition to the kick-off meeting, the contractor held several meetings
with a potential manufacturer to determine specific equipment design
requirements needed to develop the analysis tool computer code.
