Technology Development Institute
Southwest Technology Development Institute (SWTDI) installs Data
Acquisition Systems (DASs) at proposed sites for renewable energy
systems. The data from these DASs are used to perform
resource assessment for wind energy, solar energy-photovoltaic (PV),
and solar-thermal systems.
instrumentation is used to monitor
remote, engine-driven, small and medium
sized electrical grids and hybrid energy systems (up to about 250 kW)
assessments of loads and harmonic distortion. Data
systems are used to
store and transmit data for months and years.
and Fluke equipment are used for short-term
(hours and days) power quality
measurements on various PV systems, inverters, and loads associated
with PV systems.
SWTDI helps purchasers write
specifications for PV systems of any size.
Emphasis is on compliance with the National Electrical Code
practices. SWTDI also assists purchasers in evaluating
proposals for PV
systems of all sizes. SWTDI assists purchasers of
systems by designing and
specifying the components for the entire electrical balance of systems
other than the modules and array size) for PV systems of any size.
SWTDI performs electrical design reviews of any
size PV system with emphasis on
National Electrical Code compliance and good engineering
practices. Such design
reviews are best accomplished in the procurement process after the
vendor design has been
completed but before any hardware purchases are authorized.
performs acceptance testing and electrical
inspections on PV systems to include
good installation practices, code compliance, PV system dc and ac
performance, wet and dry
insulation tests, and system functioning test.
