TECNOLOGIA MARSTON
Una turbina eolica combina movimento meccanico, decisioni di controllo e conversione elettrica. Scopri come si collegano queste funzioni, il compito di ogni componente e le interfacce che definiscono la fornitura per il progetto.
01IMBARDATA ELETTRICA
L’imbardata modifica l’orientamento della navicella e del rotore attorno alla torre. In una configurazione elettrica, un motore esegue il movimento in risposta a un comando. È una funzione diversa dal passo, che cambia l’angolo della pala attorno al proprio asse.
La questione tecnica è come interagiscono rilevamento, movimento e stato operativo. La sola direzione del vento non definisce una specifica completa di controllo: contano i tempi del comando, le condizioni che consentono il movimento e la risposta all’assenza di un segnale.
FD14-50 kW / CONFIGURAZIONE
Nella configurazione attuale FD14-50 kW, un motore elettrico aziona il meccanismo di imbardata. Questa piattaforma da 50 kW dispone di un rotore tripala da 14 m e di un generatore brushless a magneti permanenti ad azionamento diretto.
All’interno della piattaforma da 50 kW
Identifica il segnale di direzione del vento e il suo riferimento. Posizione del sensore, validità del segnale e misura registrata aiutano a spiegare un comando di imbardata.
Definisci quando muoversi e quando attendere. La descrizione del controllo deve collegare errore di direzione, stato operativo e criteri di movimento del modello scelto.
Un azionamento elettrico ruota la navicella. Valuta come si arresta il movimento, come si verifica la posizione e come si accede all’azionamento per la manutenzione.
02CONVERSIONE DELLA POTENZA
Generatore, controllore e convertitore hanno ruoli diversi. Selezionarli insieme significa abbinare caratteristiche elettriche e requisiti operativi, oltre alla sola potenza nominale.
Il generatore converte in elettricità la potenza meccanica del rotore. Le sue caratteristiche elettriche sono il punto di partenza per selezionare le apparecchiature a valle. Il FD14-50 kW usa un generatore a magneti permanenti ad azionamento diretto; morsetti del generatore e uscita AC del convertitore sono punti di specifica distinti.
Il livello di controllo collega i segnali misurati alle decisioni operative. Una descrizione utile identifica ingressi, uscite, cambiamenti di stato e responsabilità delle apparecchiature. Chiarisce inoltre quali funzioni appartengono al controllore della turbina e quali alla conversione.
La conversione prepara l’uscita elettrica per la connessione prevista. Parti dalle caratteristiche di ingresso del generatore, quindi definisci tensione, frequenza e collegamento di uscita richiesti. La configurazione FD14-50 kW connessa alla rete esaminata specifica 380 V tra le fasi all’uscita del convertitore; requisiti diversi richiedono una selezione separata.
L’inseguimento del punto di massima potenza è un approccio di controllo che ricerca un punto operativo utile alla generazione al variare delle condizioni. Nei sistemi eolici, carico elettrico e comportamento del rotore sono collegati. Chiedi quale apparecchiatura applica la strategia e quali limiti del modello valgono; MPPT non è un’etichetta di compatibilità universale.
03STATI OPERATIVI
Il freno è un componente hardware. Una sequenza di protezione descrive l’evento, la risposta comandata e le condizioni di ritorno al funzionamento. La configurazione attuale FD14-50 kW usa la frenatura idraulica a disco insieme all’azionamento elettrico di imbardata. I temi seguenti costituiscono un quadro di verifica per le apparecchiature selezionate, non un elenco universale di funzioni installate.
Distingui il movimento del rotore dalla generazione elettrica. Definisci le condizioni per entrare nello stato di generazione e le misure che lo confermano. La velocità del vento di avviamento del rotore non stabilisce da sola la soglia di produzione elettrica utile.
Documenta quale dispositivo richiede l’arresto e come vengono coordinati turbina, carico elettrico e freno. Includi lo stato finale e l’indicazione che conferma il completamento.
Valuta insieme grandezza misurata, periodo di media, soglia e ritardo. Un valore di velocità del vento privo di stato operativo e condizioni di ripristino è una descrizione incompleta della protezione.
Ricostruisci cosa accade quando rete, carico o alimentazione ausiliaria non sono disponibili. Identifica le apparecchiature ancora alimentate e il dispositivo responsabile dello stato risultante della turbina.
Distingui una misura non disponibile da un valore normale. Per ogni segnale o collegamento necessario, definisci rilevamento, risposta e informazioni conservate per la diagnosi.
Definisci quali condizioni devono cessare prima del riavvio e se la conferma è locale o remota. Abbina ispezione, isolamento e accesso alla manutenzione alla documentazione del modello fornito.
04INTEGRAZIONE DEL SISTEMA
La generazione connessa alla rete, un carico isolato e un sistema ibrido pongono requisiti diversi all’interfaccia elettrica. Parti dalla destinazione dell’energia, quindi risali attraverso conversione, controllo e turbina. Uno schema unifilare rende visibili punti di collegamento e confini della fornitura.
AMBITO DELLA FORNITURA
MARSTON può valutare separatamente la fornitura di turbina, controllore e convertitore, coordinandosi con il fornitore della torre quando necessario. Per progetti ibridi, identifica apparecchiature solari, accumulo e supervisione di terzi prima di valutarne le interfacce. MARSTON attualmente non offre un prodotto di accumulo proprio.
