ABB ja aurinkosähkö

Centralized vs Distributed topology

October 6, 2017 Slide 5

DistributedBenefits:• High number of MPPTs• Modular & redundant• Easy for O&M

Challenges:• AC cabling, cable losses• Controlling large PV plants• High number of commissioning

Note:Depending on grid owner - typically demandsstep-up 0,4/20 kV, Up to 2 – 5 MWpeak max.

CentralizedBenefits:• Long track record on HW & SW• Reactive power compensation• Easy to administrate• Fast and easy commissioning

Challenges:• More DC cabling• Indoor design

Note:- Long term track record

Rocof (rate of change of frequency) suojaus:

• Jos taajuuden muutosnopeus on suurempi kuin 2 Hz/svähintään 0,15 sekunnin ajan, suoritetaan laitoksen irrotusverkosta, tämä valvonta on osana anti-island-toiminnallisuutta

• Voi olla osana keskusinvertterin toiminnallisuutta tailiityntäpisteessä erillisellä suojareleellä

Keskeisiä yksityiskohtia:

• Mahdollisimman varhaisessa vaiheessa yhteyssähköverkkoyhtiöön

• String monitoroinnilla voidaan tarkemmin seuratatuotantoa – PV- paneeleiden toimintaa, edellyttää AC jaModbus kaapelointia

• Pyörivän generaattoritehon suhde tulee olla 1,5 kertainenPV tehoon nähden

• Isommissa > 100 kWp PV-voimaloissa voi verkkoyhtiöedellyttää esimerkiksi ROCOF–suojausta ja nopeampaaAnti-islanding toimintoa (*

• yli 5 MWp voimaloiden kytkeminen 20 kVkeskijänniteverkkoon tuo mukanaan joitain tarkennuksialiityntäehtoihin

(* valvotaan verkkotaajuuden muutosnopeutta (rocof, rate ofchange of frequency)

October 6, 2017 Slide 38

Keskeisiä yksityiskohtia:

• Kiinteissä asennuksissa PV-paneelien mitoituksessasuositellaan optimi tai ylimitoitusta kertoimella 1.2 – 1.4 xinvertterin AC teho

• Mitoituksen arviointiin voidaan käyttää PVsize ohjelmaa,asennuksen yhteydessä tulee asentaa Matlab-tiedostoohjeen mukaan

• Keskusinverttereillä voidaan tuottaa loistehonkompensointia 24/7

• Pääkomponenttien toimitusajat voi olla 10-16 viikkoa

• Tyypillisesti 2 MWp blokkeina

• Keskitetty topologia kustannustehokkaampaatelineasennuksissa >1 MWp PV-voimaloissa
