1 Sistemi di telecontrollo fotovoltaici Photovoltaic remote control systems

2 la soluzione integrata ESUN è una soluzione completa per il telecontrollo degli impianti fotovoltaici. Il sistema permette di memorizzare i dati dagli inverter, dai sensori meteo, dai contatori GSE e da altri dispositivi presenti in campo per poi trasferirli via LAN, GPRS o seriale RS-232/ RS-485 tramite protocollo MODBUS RTU. ESUN è in grado di rilevare anomalie e disservizi, comunicando direttamente con gli inverter installati, e inviare direttamente dalla centralina un report giornaliero mediante SMS o . La trasmissione dati utilizza un canale di backup basato su file ftp, così da aumentare l affidabilità della trasmissione. Il sistema può gestire diversi tipi di sensori, come solarimetri, sonde di temperatura, piranometri, anemometri, pluviometri, ecc..). è disponibile nella versione con display, tastiera e batteria di backup per il rilevamento della mancanza di alimentazione. logger ESUN ESUN, logger appartenente alla famiglia delle apparecchiature CPL CONCORDIA, è il cuore del sistema di telemisura e telecontrollo di impianti fotovoltaici. Con un unico apparato è possibile comunicare con il centro dati e con altri dispositivi locali quali pannelli sinottici, PLC, reti Ethernet.

3 servizi ESUN mailing giornaliero Prevede la raccolta dei dati forniti da ogni singolo Inverter. Si può quindi rilevare la potenza istantanea e la potenza totale erogata per ogni inverter, oltre ai parametri generali di tensione e potenza istantanea e totale dell impianto, con un aggiornamento giornaliero. I dati pubblicati sul WEB possono essere visualizzati sia in forma grafica che tabellare oppure essere esportati in file di Excel per una loro successiva analisi. Una mail giornaliera informa il gestore sullo stato dell impianto al giorno precedente. meteo Il servizio meteo è fondamentale per poter gestire al meglio il proprio impianto fotovoltaico. CPL CONCORDIA propone il servizio per la rilevazione dell irraggiamento solare al metro quadro, delle temperature (temperatura esterna, temperatura dei moduli fotovoltaici, temperatura del locale tecnico). Questi dati sono importanti per poter effettuare una prima stima di efficienza dell impianto sulla base dell irraggiamento reale. Performance e ombreggiamento L analisi del funzionamento dell impianto può essere ulteriormente dettagliata fino a rilevare la corrente della singola stringa di pannelli fotovoltaici. è quindi possibile valutarne la performance e il tasso di ombreggiamento, oltre alla possibilità di rilevare il danneggiamento o furto del pannello. meteo Plus In aggiunta al servizio meteo base è possibile rilevare la direzione e la velocità istantanea del vento, oltre che la quantità di pioggia caduta nel giorno. è possibile collegare diversi tipi di sensori alla centralina tramite ingressi seriali, analogici e digitali. telelettura contatori fiscali Per una più precisa analisi economica è fondamentale poter acquisire i dati della potenza ed energia, ceduta al gestore, letti direttamente dal contatore fiscale. Se il contatore è predisposto per la telelettura sarà possibile ottenere una più precisa previsione dei ricavi derivanti dalla effettiva vendita dell energia elettrica, oltre alla possibilità di monitorare costantemente il rendimento economico dell impianto, e quindi un preciso flusso di cassa. Nei grandi impianti in cui è presente un contatore (dedicato o GSE), è possibile acquisire i dati per quantificare con esattezza l importo degl incentivi ricavati nel flusso di cassa. I dati letti dai contatori GSE possono inoltre essere confrontati coi dati di produzione degli inverter, ottenendo un controllo più completo delle funzionalità dell impianto. analisi ProDuzione energetica Sul portale web è possibile visualizzare l energia prodotta in un arco temporale orario, giornaliero, mensile e annuale. L energia reale può essere confrontata con quella teorica calcolata in base all irraggiamento reale e teorico. Utilizzando infine il dato di Performance Ratio calcolato dal sistema, risulta possibile analizzare il degrado dell impianto anno per anno. alert Servizio di Alert sullo stato degli inverter e degli altri componenti predisposti (dai pannelli ai teleruttori) con l invio di sms ed direttamente ai tecnici reperibili. Gli allarmi vengono spediti direttamente dall apparato così da garantire una sorveglianza 24h su 24h. antintrusione ViDeosorVeglianza Il logger ESUN dispone di ingressi dedicati al telecontrollo delle centraline di videosorveglianza, così da garantire ridondanza e avvertire nel caso di malfunzionamento del sistema di allarme principale. Il sistema è compatibile con gli impianti di sicurezza realizzati da CPL CONCORDIA e non solo. telecomandi Servizio avanzato di telecontrollo: grazie a teleruttori motorizzati o servocomandi è possibile intervenire per accendere o spegnere le luci nei locali o presso gli impianti di videosorveglianza, attivare ventilatori o attuare il riarmo dei teleruttori principali senza recarsi sul posto. DisPlaY locale Forma di monitoraggio dell andamento della produzione di energia elettrica realizzata attraverso la predisposizione di pannelli sinottici a messaggi variabili in prossimità dell impianto. Si visualizzano la potenza erogata istantanea, i kwh erogati e la quantità di CO2 non emessa in atmosfera. monitoraggio Via Web Fornisce le informazioni in tempo reale sullo stato dell impianto e sul suo rendimento. Si visualizzano informazioni sullo stato della produttività dei pannelli, dell energia immessa in rete dall inverter, sulla lettura dei contatori fiscali e sullo stato diagnostico dei dispositivi. HelP H24 Servizio di manutenzione con addetti CPL CONCORDIA reperibili 24 ore su 24. I messaggi di allarme per guasti vengono inviati direttamente al personale CPL e/o al personale che gestisce l impianto. contact center Servizio di segnalazione guasti e malfunzionamenti fornito da CPL CONCORDIA. Operatori di telecontrollo specializzati possono ricevere le segnalazioni dalle centraline e chiamare i reperibili assicurandosi che la comunicazione venga recapitata. training Attività di formazione, svolta da tecnici CPL CONCORDIA, per la gestione e la manutenzione degli impianti fotovoltaici.
