A C++ SIGNAL PROCESSING CLASS LIBRARY FOR POWER SYSTEM TRANSIENTS

摘要

The modelling of power system components using experimental system identification algorithms is a promising technique for overcoming a lack of detailed manufacturer information. For that reason, a C++ signal processing class library has been developed and is here presented. That enables the user to program various algorithms in an intuitive, object-oriented way. Moreover, this work shows two sample applications of the library usage: a comparison of frequency response analysis (FRA) determination in frequency and time-domain studies possible sources of errors and a transient recovery voltage calculation on a transformer from FRA data shows the application of a new technique for gaining circuit-breaker dimensioning parameters.
