TECHNOLOGIA MARSTON
Turbina łączy ruch mechaniczny, decyzje sterowania i przekształcanie elektryczne. Poznaj powiązania funkcji, role elementów i interfejsy określające sprzęt dla projektu.
01ELEKTRYCZNY OBRÓT GONDOLI
Obrót gondoli zmienia orientację gondoli i wirnika względem wieży. W układzie elektrycznym ruch wykonuje silnik w odpowiedzi na polecenie sterowania. To inna funkcja niż regulacja kąta łopaty wokół jej własnej osi.
Istotne pytanie techniczne dotyczy współpracy pomiarów, ruchu i stanu pracy. Sam kierunek wiatru nie stanowi pełnej specyfikacji sterowania: ważne są czas wydania polecenia, warunki dopuszczające ruch i reakcja na brak sygnału.
FD14-50 kW / KONFIGURACJA
W obecnej konfiguracji FD14-50 kW mechanizm obrotu gondoli napędza silnik elektryczny. Platforma 50 kW ma trójłopatowy wirnik 14 m i bezszczotkowy generator z magnesami trwałymi oraz napędem bezpośrednim.
Wewnątrz platformy 50 kW
Wskaż sygnał kierunku wiatru i jego punkt odniesienia. Lokalizacja czujnika, poprawność sygnału i zapis pomiaru pomagają wyjaśnić polecenie obrotu gondoli.
Określ, kiedy poruszać gondolą, a kiedy czekać. Opis sterowania powinien wiązać błąd kierunku, stan pracy i kryteria ruchu wybranego modelu.
Napęd elektryczny obraca gondolę. Oceń sposób zatrzymania ruchu, sprawdzania położenia i dostępu serwisowego do napędu.
02PRZEKSZTAŁCANIE ENERGII
Generator, sterownik i przekształtnik pełnią różne role. Wspólny dobór oznacza dopasowanie parametrów elektrycznych i wymagań pracy, a nie tylko mocy znamionowej.
Generator przekształca moc mechaniczną wirnika w energię elektryczną. Jego parametry są punktem wyjścia do doboru urządzeń za generatorem. FD14-50 kW wykorzystuje generator z magnesami trwałymi i napędem bezpośrednim; zaciski generatora i wyjście AC przekształtnika to odrębne punkty specyfikacji.
Warstwa sterowania łączy pomiary z decyzjami operacyjnymi. Przydatny opis wskazuje wejścia, wyjścia, zmiany stanów i odpowiedzialność urządzeń. Pokazuje też funkcje sterownika turbiny oraz te należące do przekształtnika.
Przekształcanie przygotowuje energię do planowanego połączenia. Zacznij od parametrów wejścia od generatora, potem określ napięcie, częstotliwość i układ wyjściowy. Przeanalizowana konfiguracja sieciowa FD14-50 kW określa 380 V międzyfazowo na wyjściu przekształtnika; inne wymagania projektu wymagają odrębnego doboru.
Śledzenie punktu mocy maksymalnej to metoda sterowania poszukująca użytecznego punktu pracy przy zmiennych warunkach. W systemach wiatrowych obciążenie elektryczne i zachowanie wirnika są powiązane. Zapytaj, które urządzenie realizuje strategię i jakie limity modelu obowiązują; MPPT nie jest uniwersalnym oznaczeniem zgodności.
03STANY PRACY
Hamulec jest elementem sprzętowym. Sekwencja ochronna opisuje zdarzenie, zadaną reakcję i warunki powrotu do pracy. Obecny FD14-50 kW wykorzystuje hamowanie hydrauliczne tarczowe obok elektrycznego napędu obrotu gondoli. Poniższe zagadnienia stanowią ramy oceny wybranego sprzętu, nie uniwersalną listę wyposażenia.
Oddziel ruch wirnika od generacji elektrycznej. Określ warunki wejścia w stan generacji i pomiary, które go potwierdzają. Prędkość wiatru uruchamiająca wirnik sama nie wyznacza progu użytecznej generacji.
Udokumentuj urządzenie zlecające zatrzymanie oraz koordynację turbiny, obciążenia elektrycznego i hamulca. Uwzględnij stan końcowy i potwierdzenie zakończenia.
Rozpatruj wspólnie wielkość mierzoną, czas uśredniania, próg i opóźnienie. Wartość prędkości wiatru bez stanu pracy i warunków resetowania nie opisuje kompletnie zabezpieczenia.
Prześledź reakcję na brak sieci, odbioru lub zasilania pomocniczego. Wskaż urządzenia, które pozostają zasilane, i element odpowiedzialny za wynikowy stan turbiny.
Odróżnij niedostępny pomiar od prawidłowej wartości. Dla każdego wymaganego sygnału lub połączenia określ wykrywanie, reakcję i dane zachowywane do diagnostyki.
Określ, które warunki muszą ustąpić przed ponownym rozruchem i czy potwierdzenie jest lokalne czy zdalne. Dopasuj inspekcje, odłączenie i dostęp serwisowy do dokumentacji dostarczonego modelu.
04INTEGRACJA SYSTEMU
Generacja sieciowa, odbiór izolowany i system hybrydowy stawiają różne wymagania interfejsowi elektrycznemu. Zacznij od miejsca wykorzystania energii, następnie przejdź wstecz przez przekształcanie, sterowanie i turbinę. Schemat jednokreskowy pokazuje punkty połączeń i granice urządzeń.
