Vetrne turbine - 25-3. del: Komunikacije za spremljanje in nadzor vetrnih elektrarn - Modeli za izmenjavo informacij

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 tej skupini standardov.
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 model vetrne elektrarne, (2) model za izmenjavo informacij in (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, npr. »hitrost rotorja vetrne turbine« ali »skupna proizvodnja energije v določenem časovnem intervalu«, se modelira in postane dostopna. Informacija, ki se modelira skladno s skupino standardov IEC 61400-25, je opredeljena v standardu 61400-25-2;
– 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 opredeljuje samo način modeliranja informacij, izmenjavo informacij in preslikavo v določen komunikacijski protokol. Skupina standardov IEC 61400-25 ne določa, kako in kje je treba izvesti komunikacijski vmesnik, programski vmesnik in priporočila za izvajanje. Vendar je cilj skupine standardov IEC 61400-25 omogočiti dostop do informacij posamezne komponente vetrne elektrarne (kot na primer vetrne turbine) prek ustrezne logične naprave.
Ta del standarda IEC 61400-25 določa vmesnik storitve za abstraktno komunikacijo, ki opisuje izmenjavo informacij med odjemalcem in strežnikom za:
– dostop do podatkov in njihov priklic;
– nadzor naprave;
– poročanje o dogodku in beleženje;
– samoopis naprav (slovar podatkov o napravi);
– vrste podatkov in odkrivanje vrste podatkov.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61400-25-3 has been prepared by IEC technical committee 88:

Wind turbines.

• Reduction of overlap between standards and simplification by increased referencing.

This edition includes the following significant technical changes with respect to the previous

edition:
a) Add subscription and remove subscription services have been removed.

b) Tables in Clause 9 indicating expected services have been replaced by tables in a new

Annex D including ACSI conformance statements for clients and servers.

c) Technical issues (“Tissues”) for IEC 61850-7-2 edition 2 have been considered and

changes have been made accordingly.

Technical issues (“Tissues”), as collected by the IEC 61400-25 users group USE61400-25,

have been considered, but no technical issues were registered for edition 1.

A list of all parts of the IEC 61400 series, under the general title Wind turbines, can be found

on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION

The IEC 61400-25 series defines communications for monitoring and control of wind power

plants. The modeling approach of the IEC 61400-25 series has been selected to provide

abstract definitions of classes and services such that the specifications are independent of

specific protocol stacks, implementations, and operating systems. The mapping of these

abstract classes and services to a specific communication profile is not inside the scope of

this part (IEC 61400-25-3) but inside the scope of IEC 61400-25-4.

This part of IEC 61400-25 defines services of the model of the information exchange of

intelligent electronic devices in wind power plants. The services are referred to as the abstract

communication service interface (ACSI). The ACSI has been defined so as to be independent

of the underlying communication systems.
The information exchange model is defined in terms of
– a hierarchical class model of all information that can be accessed,
– information exchange services that operate on these classes,
– parameters associated with each information exchange service.

The ACSI description technique abstracts away from all the different approaches to implement

the cooperation of the various devices.

These abstract service definitions are mapped into concrete object definitions that are to be

used for a particular protocol. Mapping to specific protocol stacks is specified in

IEC 61400-25-4.

NOTE 1 Abstraction in ACSI has two meanings. Firstly, only those aspects of a real device (for example, a rotor)

or a real function that are visible and accessible over a communication network are modelled. This abstraction

leads to the hierarchical class models and their behaviour defined in IEC 61400-25-2. Secondly, the ACSI abstracts

from the aspect of concrete definitions on how the devices exchange information; only a conceptual cooperation is

defined. The concrete information exchange is defined in IEC 61400-25-4.

NOTE 2 Performance of the IEC 61400-25 series implementations are application specific. The IEC 61400-25

series does not guarantee a certain level of performance. This is beyond the scope of the IEC 61400-25 series.

However, there is no underlying limitation in the communications technology to prevent high speed application

(millisecond level responses).

WIND TURBINES –
Part 25-3: Communications for monitoring
and control of wind power plants –
Information exchange models
1 Scope

The focus of the IEC 61400-25 series is on the communications between wind power plant

components such as wind turbines and actors such as SCADA systems. Internal

communication within wind power plant components is outside the scope of the IEC 61400-25

series.

The IEC 61400-25 series is designed for a communication environment supported by a client-

server model. Three areas are defined, that are modelled separately to ensure the scalability

of implementations: (1) wind power plant information models, (2) information exchange model,

and (3) mapping of these two models to a standard communication profile.

The wind power plant information model and the information exchange model, viewed

together, constitute an interface between client and server. In this conjunction, the wind power

plant information model serves as an interpretation frame for accessible wind power plant

data. The wind power plant information model is used by the server to offer the client a

uniform, component-oriented view of the wind power plant data. The information exchange

model reflects the whole active functionality of the server. The IEC 61400-25 series enables

connectivity between a heterogeneous combination of client and servers from different

manufacturers and suppliers.

As depicted in Figure 1, the IEC 61400-25 series defines a server with the following aspects:

– information provided by a wind power plant component, e. g., “wind turbine rotor speed” or

“total power production of a certain time interval” is modelled and made available for

access. The information modelled in the IEC 61400-25 series is defined in
IEC 61400-25-2;

– services to exchange values of the modelled information defined in IEC 61400-25-3;

– mapping to a communication profile, providing a protocol stack to carry the exchanged

values from the modelled information (IEC 61400-25-4).

The IEC 61400-25 series only defines how to model the information, information exchange

and mapping to specific communication protocols. The IEC 61400-25 series excludes a

definition of how and where to implement the communication interface, the application

program interface and implementation recommendations. However, the objective of the

IEC 61400-25 series is that the information associated with a single wind power plant

component (such as a wind turbine) is accessible through a corresponding logical device.

This part of IEC 61400-25 specifies an abstract communication service interface describing

the information exchange between a client and a server for:
– data access and retrieval,
– device control,
– event reporting and logging,
– self-description of devices (device data dictionary),
– data typing and discovery of data types.
