Transformer Load Simulator (TLS) Software
The transient behaviour of transformer load
versus the various temperatures and other life reducing parameters is of
increasing concern to utilities because of loading, security of supply
and life expectancy reasons. These conflicting requirements can only be
satisfied with increasingly complex analysis. The degree of complexity
required is well illustrated in AS 2374.7 (IEC 354), devoting three
parts out of four to methods, which simplify the required calculations
just to avoid the use of transient equations.
Utilities need to assess transformer capabilities above nameplate rating when;
A proprietary program of Wasinger Transformers Pty. Ltd. determines
transient temperatures in accordance with the previous and present
Australian standards. It comprises separate databases for the
transformers, load- and ambient temperature profiles, which can be
freely combined to suit a particular set of circumstances. It further
caters for two cooling modes, which permit switching at half-hourly
intervals just as the transformer cooling is switched from the
transformer winding temperature indicator. The output routines calculate
ambient-, oil - and winding hot spot temperatures and also life
consumption over a daily cycle either as input or scaled to user-defined
limits. Different routines are provided to permit solutions to various
problems. Comprehensive help screens are provided and all output tables
as well as the transformer databases can be printed hard copy.
A free-issue CD is available for demonstration purposes. Full Licences cost $A1900 plus GST for installation on the first PC with subsequent licences half price.
