Wind turbines - Part 25-2: Communications for monitoring and control of wind power plants - Information models

IEC 61400-25-2:2015 specifies the information model of devices and functions related to wind power plant applications. In particular, it specifies the compatible logical node names, and data names for communication between wind power plant components. This includes the relationship between logical devices, logical nodes and data. The names defined in the IEC 61400-25 series are used to build the hierarchical object references applied for communicating with components in wind power plants. Main changes with respect to the previous edition consist of: - harmonization with newer editions of IEC 61850 standards; - reduction of overlap between standards and simplification by increased referencing, - extension of data objects for operation of smart grids, - extended and enhanced semantics for existing data objects, etc.

Windenergieanlagen - Teil 25-2: Kommunikation für die Überwachung und Steuerung von Windenergieanlagen - Informationsmodelle

Eoliennes - Partie 25-2: Communications pour la surveillance et la commande des centrales éoliennes - Modèles d’information

L'IEC 61400-25-2:2015 spécifie le modèle d'information des dispositifs et des fonctions liés aux applications des centrales éoliennes. Elle spécifie notamment les noms de noeud logique compatible et les noms de données utilisés dans la communication entre les composants des centrales éoliennes, y compris la relation entre les dispositifs logiques, les noeuds logiques et les données. Les noms définis dans la série IEC 61400-25 sont utilisés pour établir les références à un objet hiérarchique s'appliquant dans le cadre de la communication avec les composants des centrales éoliennes. Cette nouvelle édition comporte les changements importants suivants par rapport à l'édition précédente: - l'harmonisation avec de nouvelles éditions de la série IEC 61850, - la réduction de l'écart entre les normes et la simplification par un référencement amélioré, - l'extension des objets de données pour fonctionnement des réseaux intelligents, - l'extension et l'amélioration de la sémantique pour les objets de données existants, etc.

Sistemi generatorjev vetrne turbine - 25-2. del: Komunikacije za spremljanje in nadzor vetrnih elektrarn - Informacijski modeli

Skupina standardov IEC 61400-25 se osredotoča na komunikacije med komponentami vetrnih elektrarn, kot so vetrne turbine, in elementi, kot so sistemi SCADA. Komunikacije znotraj komponent vetrnih elektrarn niso zajete v skupini standardov IEC 61400-25.
Skupina standardov IEC 61400-25 je zasnovana za komunikacijsko okolje, ki ga podpira model odjemalec-strežnik. Opredeljena so tri področja, ki so oblikovana posebej, da se zagotovi nadgradljivost uporabljenih različic:
1) informacijski modeli vetrnih elektrarn,
2) model za izmenjavo informacij,
3) preslikava teh dveh modelov v standardni komunikacijski profil.
Informacijski model vetrne elektrarne in model za izmenjavo informacij skupaj sestavljata vmesnik med odjemalcem in strežnikom. Informacijski model vetrne elektrarne se uporablja kot okvir za interpretacijo dostopnih podatkov vetrne elektrarne. Strežnik uporablja informacijski model vetrne elektrarne, da odjemalcu ponuja enoten pregled podatkov vetrne elektrarne, ki je osredotočen na komponente elektrarne. Model za izmenjavo informacij predstavlja aktivne funkcije strežnika. Skupina standardov IEC 61400-25 omogoča povezljivost med raznolikimi odjemalci in strežniki različnih proizvajalcev in dobaviteljev.
Kot prikazuje slika 1, skupina standardov IEC 61400-25 opredeljuje strežnik z naslednjimi vidiki:
– informacija, ki jo posreduje komponenta vetrne elektrarne, na primer »hitrost rotorja vetrne turbine« ali »skupna proizvodnja energije v določenem časovnem intervalu«, se modelira in postane dostopna;
– storitve za izmenjavo vrednosti modelirane informacije so opredeljene v standardu IEC 61400-25-3;
– preslikava v komunikacijski profil, kar zagotavlja sklad protokolov za prenos izmenjanih vrednosti iz modelirane informacije (IEC 61400-25-4).
Skupina standardov IEC 61400-25 opredeljuje samo način modeliranja informacij, izmenjavo informacij in preslikavo v določen komunikacijski protokol. Standard ne določa, kako in kje je treba izvesti komunikacijski vmesnik, programski vmesnik in priporočila za izvajanje. Vendar je cilj standarda omogočiti dostop do informacij posamezne komponente vetrne elektrarne (na primer vetrne turbine) prek ustrezne logične naprave.
Standard IEC 61400-25-2 določa informacijski model naprav in funkcij, povezanih z aplikacijami vetrnih elektrarn. Določa zlasti imena združljivih logičnih vozlišč in imena podatkov za komunikacijo med komponentami vetrne elektrarne. Sem spada razmerje med logičnimi napravami, logičnimi vozlišči in podatki. Imena, določena v skupini standardov IEC 61400-25, se uporabljajo za izdelavo hierarhičnih sklicev na predmete, ki se uporabljajo za komunikacijo s komponentami v vetrnih elektrarnah.
Ta del standarda IEC 61400-25 določa običajne vrste atributov in običajne razrede podatkov, povezane z uporabo vetrnih turbin. Določa zlasti običajne razrede podatkov za:
• vrednost nastavitvene točke,
• vrednost stanja,
• alarm,
• ukaz,
• štetje dogodkov,
• časovno načrtovanje stanj,
• stanje nastavitve alarma.
Naprave, v katerih se uporablja informacijski model, opisan v tem delu, izberejo enega ali več logičnih vozlišč, kot zahteva aplikacija.
OPOMBA 1: Skupina standardov IEC 61400-25 se osredotoča na skupne informacije, ki niso vezane na določenega prodajalca. Te elemente informacij, ki se običajno zelo razlikujejo glede na uporabo, značilno za določenega prodajalca, je mogoče na primer določiti v dvostranskih pogodbah ali s strani skupin uporabnikov.
OPOMBA 2: V tem delu izobraževalno gradivo ni na voljo.
