The sensitive industrial loads and critical commercial operations suffer from harmonics problems which can cost significant loss per incident based on process down-time, loss production, idle work forces and other factors. To overcome such problems, utility companies have made efforts to improve the quality and reliability of their electric power by introducing distribution static compensator (D-STATCOM). However, up to now, many research are going on D-STATCOM control scheme, suitable pulse and transformer design, dc capacitance effect and involvement with many power quality problems. This paper deals with the modelling and simulations of D-STATCOM model focus with the pulse selection, transformer design configuration and test distribution system. The issue of harmonics in the D-STATCOM is addressed by considering a 24-pulse so as to eliminate the generated harmonics. The harmonics eliminating performance of the D-STATCOM in 12-pulse, 24-pulse and 48-pulse are also investigated.
W artykule opisano budowę modelu i symulacje kompensatora statycznego D-STATCOM. Przedstawiono zagadnienie liczby pulsów, konfiguracji transformatora oraz przeprowadzono testy systemu energetycznego. Analizie poddano zagadnienie eliminacji wyższych harmonicznych w układach 12-, 24- oraz 48-pulsowym.
