Development of an emulation platform for synchronous machine power generation system using a nonlinear functional level model
PublicationThe article presents the Power Hardware in the Loop (PHIL) approach for an autonomous power system analysis based on the synchronous generator model incorporating magnetic saturation effects. The model was prepared in the MATLAB/Simulink environment and then compiled into the C language for the PHIL platform implementation. The 150 kVA bidirectional DC/AC commercial-grade converter was used to emulate the synchronous generator....

Zastosowanie modułu symulacji dynamicznej programu Autodesk Inventor do badań właściwości dynamicznych odbieraków prądu
PublicationW pracy przedstawiono wybrane zagadnienia komputerowego modelowania 3D podzespołów kolejowego odbieraka prądu typu 160 EC oraz jego złożenie jako integralnej konstrukcji w programie Autodesk Inventor. Omówiono sposób implementacji modelu 3D odbieraka w Module Symulacji Dynamicznej (MSD). W symulacji komputerowej badano proces unoszenia się odbieraka pod wpływem zadanego momentu obrotowego. Pokazano wybrane wyniki symulacji dynamicznej...

Wpływ parametrów tarcia w przegubach modelu odbieraka prądu na jego właściwości dynamiczne
PublicationJednym z istotnych podzespołów elektrycznego pojazdu szynowego jest odbierak prądu. Pogorszenie parametrów odbieraka skutkuje jego niewłaściwą współpracą z siecią jezdną, co przyspiesza zużycie obydwu tych elementów układu odbioru prądu, generując znaczne koszty eksploatacyjne. W niekorzystnych warunkach może prowadzić do uszkodzenia sieci jezdnej, co z reguły wywołuje znaczne zaburzenia w ruchu pociągów i generuje duże koszty....

Badania dynamiki ruchu odbieraków prądu z wykorzystaniem programu Autodesk Inventor
PublicationRozwój kolei dużych prędkości stawia coraz wyższe wymagania w zakresie konstrukcji i utrzymania sieci trakcyjnych oraz odbieraków prądu. Głównym problemem technicznym jest konieczność zapewnienia ciągłości styku pomiędzy przewodem jezdnym a nakładkami stykowymi ślizgacza. Współpraca pomiędzy elementami zestyku ślizgowego zależy w istotnym stopniu od zastosowanej konstrukcji odbieraka i wartości parametrów, zwłaszcza tych, które...

Lagrangian model of an isolated dc-dc converter with a 3-phase medium frequency transformer accounting magnetic cross saturation
PublicationThis article presents a nonlinear equivalent circuit model of an isolated dc-dc converter with a 3-phase medium frequency transformer. The model takes into account the magnetic cross saturation of the 3-phase core-type magnetic circuit. The model is suitable in detailed electromagnetic transient simulations of power systems involving isolated dc-dc converters. The model is developed using the Lagrange energy method. It involves...

High Q-factor Microwave Fabry-Perot Resonator With Distributed Bragg Reflectors
PublicationZrealizowany został rezonator Fabry-Perot pracujący na częstotliwości 39 GHz i wykorzystujący dwie pary ćwierćfalowych kwarcowych reflektorów Bragga. Dla fali o długości 98.26 mm otrzymano dobroć ok. 560,000, co oznacza 4.3-krotny wzrost w porównaniu z identycznym rezonatorem bez reflektorów Bragga. Analizę problemu wykonano przy pomocy metody różnic skończonych w dziedzinie częstotliwości (FDFD) i porównano z uproszczonym rozwiązaniem...
