1. Introduction
(a) These Generating System Design Data Sheets and Generating System Setting Data
Sheets (“Data Sheets”) are made in accordance with clause S5.5.7(a) and (b) of the
National Electricity Rules (Rules), which states:
"NEMMCO must, subject to paragraph (b), develop and publish by 1 March 2008, in
accordance with the Rules consultation procedures:
(1) a Generating System Design Data Sheet describing, for relevant technologies, the
generating system design parameters of generating units and generating systems
including plant configurations, impedances, time constants, non-linearities, ratings
and capabilities, to be provided under clauses S5.2.4 and this schedule 5.5;
(2) a Generating System Setting Data Sheet describing, for relevant generation and
control system technologies, the protection system and control system settings of
generating units and generating systems including configurations, gains, time
constants, delays, deadbands, non-linearities and limits, to be provided under
clauses S5.2.4 and this schedule 5.5; and
(3) Generating System Model Guidelines describing, for relevant generation and control
system technologies, NEMMCO’s requirements when developing mathematical
models for generating units and generating systems, including the impact of their
control systems and protection systems on power system security,
and there must be a Generating System Design Data Sheet, Generating System Setting
Data Sheet and Generating System Model Guidelines in place at all times after that
date."
This document contains both of the Data Sheets described in S5.5.7 above.
(b) These Data Sheets commence on 29 February 2008.
(c) These Data Sheets may only be amended in accordance with clause S5.5.7(c) of the
Rules which states:
"Any person may submit a request (with written reasons) to NEMMCO to amend the
Generating System Design Data Sheet, Generating System Setting Data Sheet or the
Generating System Model Guidelines and NEMMCO must conduct the Rules
consultation procedures in relation to the request."
(d) If there is any inconsistency between these Data Sheets and the Rules, the Rules will
prevail to the extent of that inconsistency.
2. Purpose
The purpose of developing and publishing the Data Sheets is set out in S5.5.7(b) which
states:
© AEMO
Prepared by: Planning Department Document No: 118-0010 Version No: 1.0
Effective Date: 29/02/2008 Status: Final
Page 7 of 78
"When developing and publishing the Generating System Design Data Sheet, Generating System Setting Data Sheet and Generating System Model Guidelines under paragraph (a), NEMMCO must have regard to the purpose of developing and publishing the sheets and guidelines which is to:
(1) allow generating units and generating systems to be mathematically modelled by
NEMMCO in load flow and dynamic stability assessments with sufficient accuracy to
permit:
(i) the power system operating limits for ensuring power system security to be
quantified with the lowest practical safety margins;
(ii) proposed access standards and performance standards of generating units and
generating systems to be assessed; and
(iii) settings of control systems and protection systems of generating units,
generating systems and networks to be assessed and quantified for maximum
practical performance of the power system; and
(2) identify for each type of data its category in terms of clause S5.5.2."
The Rules also contemplate that Network Service Providers and AEMO will use the data
obtained from the Data Sheets for their own purposes. For example S5.2.4(a) allows a
Network Service Provider or AEMO to request all data specified in Schedule 5.5 (which
includes the Data Sheets) from a Generator or person who is negotiating a connection
agreement.
3. Application of the Data Sheets
Clause S5.2.4 sets out that:
"A Generator or person who is negotiating a connection agreement with a Network Service Provider must promptly on request by NEMMCO or the Network Service Provider provide all data in relation to that generating system specified in schedule 5.5."
and clause S5.5.4 of Schedule 5.5 states that:
"The documents and schedules applicable to each class of Registered Participant are as follows:
(a) Generators: the Generating System Model Guidelines, Generating System Design
Data Sheet and Generating System Setting Data Sheet. "
Subsets of the data in the Data Sheets are required at various stages, based on the data
category. Data categories are described in clause S5.5.2, which states:
"…Data is coded in categories, according to the stage at which it is available in the build-up of data during the process of forming a connection or obtaining access to a network, with data acquired at each stage being carried forward, or enhanced in subsequent stages, e.g. by testing.

Preliminary system planning data
This data is required for submission with the application to connect, to allow the Network
Service Provider to prepare an offer of terms and conditions for a connection agreement
and to assess the requirement for, and effect of, network augmentation or extension
options. Such data is normally limited to the items denoted as Standard Planning Data (S)
in the Generating System Model Guidelines, Generating System Design Data Sheet,
Generating System Setting Data Sheet and in schedules 5.5.3 to 5.5.5.
The Network Service Provider may, in cases where there is reasonable doubt as to the
viability of a proposal, require the submission of other data before making an offer to
connect or to amend a connection agreement.
Registered system planning data
This is the class of data which will be included in the connection agreement signed by
both parties. It consists of the preliminary system planning data plus those items denoted
in the attached schedules as Detailed Planning Data (D). The latter must be submitted by
the Registered Participant in time for inclusion in the connection agreement.
Registered data
Registered Data consists of data validated and agreed between the Network Service
Provider and the Registered Participant, such data being:
(a) prior to actual connection and provision of access, data derived from manufacturers'
data, detailed design calculations, works or site tests etc. (R1); and
(b) after connection, data derived from on-system testing (R2).
All of the data will, from this stage, be categorised and referred to as Registered Data; but
for convenience the schedules omit placing a higher ranked code next to items which are
expected to already be valid at an earlier stage."
In interpreting the requirement for on-system testing for the purpose of deriving „R2‟
parameters:
the normal requirement is that each generating unit must be tested to derive „R2‟
parameters; or
“type-testing” 1 of plant 2 is permissible, where the Generator can demonstrate that:
– the plant tested is representative of other plant items in the same generating system
– this includes, for example, plant such as synchronous machines or asynchronous
1 site tests to verify parameters for a single generating unit that are representative for all generating
units for plant with the same design.
2 plant items could be, for example, synchronous machines, asynchronous machines, control systems
within a generating unit, limiters within a generating unit’s control systems, etc.

machines with identical design and manufacture, but excludes plant that has settings
that can be applied on-site; or
– for plant that can have settings applied on-site (e.g. control systems, limiters, etc.)
the plant must be digital and the software version and parameters must be identical.
Clause 5.3.3(c) describes the data required with a connection application:
"(c) Within 20 business days after receipt of the connection enquiry and all such additional
information (if any) advised under clause 5.3.2(b) or, if the Connection Applicant has
requested the Local Network Service Provider to process the connection enquiry
under clause 5.3.2(d), within 20 business days after receipt of that request, the
Network Service Provider must provide to the Connection Applicant written advice of
all further information which the Connection Applicant must prepare and obtain in
conjunction with the Network Service Provider to enable the Network Service Provider
to assess an application to connect including:
…
(3) a list of the technical data to be included with the application to connect, which
may vary depending on the connection requirements and the type, rating and
location of the facility to be connected and will generally be in the nature of the
information set out in schedule 5.5 but may be varied by the Network Service
Provider as appropriate to suit the size and complexity of the proposed facility to
be connected;
…”
The data forms part of the Connection Agreement (clause s5.5.1) and if there is any
inconsistency between it and what was previously advised, it must be updated, as described
in clause 5.4.2:
“(a) At any stage prior to commissioning the facility in respect of a connection if there is an
inconsistency between the proposed equipment and the connection agreement
including the performance standards, the Registered Participant or the person
intending to be registered as a Generator must:
(1) advise the relevant Network Service Provider and, if the inconsistency relates to
performance standards, NEMMCO, in writing of the inconsistency; and
(2) if necessary, negotiate in good faith with the Network Service Provider any
necessary changes to the connection agreement."
Clause S5.2.4(b) also provides guidance on when model information needs to be provided:
"(b) A Generator, or person required under the Rules to register as the Generator in
respect of a generating system comprised of generating units with a combined
nameplate rating of 30 MW or more, by the earlier of:
(1) the day on which an application to connect is made under clause 5.3.4(a);

Prepared by: Planning Department Document No: 118-0010 Version No: 1.0
Effective Date: 29/02/2008 Status: Final
Page 10 of 78
(2) the day on which amendments to performance standards are submitted under
clause 5.3.9(b);
(3) three months before commissioning of a generating system or planned alteration
to a generating system; or
(4) 5 business days before commissioning of a generating system alteration that is
repairing plant after a plant failure, if plant performance after the alteration will
differ from performance prior to the plant failure,
must provide:
(5) to NEMMCO and the relevant Network Service Providers (including the relevant
Transmission Network Service Provider in respect of an embedded generating
unit) the following information about the control systems of the generating
system:
(i) a set of functional block diagrams, including all functions between feedback
signals and generating system output;
(ii) the parameters of each functional block, including all settings, gains, time
constants, delays, deadbands and limits; and
(iii) the characteristics of non-linear elements,
with sufficient detail for NEMMCO and Network Service Providers to perform load
flow and dynamic simulation studies; and
(6) to NEMMCO, model source code associated with the model in subparagraph (5)
in an unencrypted form suitable for at least one of the software simulation
products nominated by NEMMCO and in a form that would allow conversion for
use with other software simulation products by NEMMCO."
Clause S5.2.4(d) further requires that model information is updated following commissioning
or testing in accordance with clause 5.3.7:
"(d) The Generator must update the information provided under paragraph (b) within 3
months after commissioning tests or other tests undertaken in accordance with clause
5.7.3 are completed."
4. Definitions and interpretation
(a) In this document, a word or phrase in this style, has the meaning set out opposite that
word or phrase in the Glossary (Schedule 1) of this document.
(b) If a word or phrase in this style is not defined in the Glossary, the term has the same
meaning as given to that term in the Rules.
(c) In this document, unless the context otherwise requires, this document shall be
interpreted in accordance with Schedule 2 of the National Electricity Law.

5. How to complete the Data Sheets
This document serves the purpose of both Data Sheets by including, for each plant item that
is part of the generating system, the data requirements for the Generating System Design
Data Sheet under a heading of “Design Data Sheet” and the Generating System Settings
Data Sheet requirements under a heading of “Setting Data Sheet”.
Generators are required to provide information on all plant components that are relevant to
their generating system. These Data Sheets provide data provision requirements for each
component.
In the case of generating systems comprising multiple types of generating units, the
Generator should complete information for
the generating system;
each type of identical generating unit, detailing to which generating units the data
applies;
each identical plant component, detailing to which generating units the data applies.
The following tables provide a guide to which Data Sheets should be selected for most
typical generating systems. These are a guide only. Other combinations of plant might be
envisaged (for example, a steam turbine driving an asynchronous machine), in which case
the appropriate plant Data Sheets should be substituted for those listed in the table.
Where a generating system consists of multiple identical generating units (or several types of
identical generating unit) only one data set need be completed for each distinct generating
unit type.
Where possible, specific data requirements have been listed, based on typical
implementations of the technology. For some newer technologies, requirements have been
requested in a general manner – once the technologies become more established, the
general requirements will be replaced with more specific ones.
In the Data Sheets, there are a number of references to the provision of a „functional block
diagram‟. The functional block diagram should show:
functional structure;
mathematical model details within each block (gains, time constants and non-linear
elements);
input and output quantities for each function block where this interfaces with any other
plant item; and
units for functional block diagram input and output quantities (if per-unit, specify base).
In relation to control systems, protection systems and plant limits relevant information must
be provided for a range of types of power system analysed from load flow, transient stability,
oscillatory stability and medium and long term stability studies. Therefore, information on any

Effective Date: 29/02/2008 Status: Final
Page 12 of 78
control systems, protection systems and plant limits that may affect the performance of plant
over a range of timeframes must be provided – i.e. .from “instantaneous” performance to up
to 10 minutes.
5.1 Variation Request
In some cases, a particular Generator’s plant may not “fit” the data provision requirements of
the Data Sheets, or provision of the data according to the required format may be misleading
(e.g. if certain critical data is missing). Under these conditions, a Generator must advise the
relevant Network Service Provider and AEMO, providing suitable technical evidence, and
seek their approval in writing to adjust or augment the data required by the Data Sheets.
Where a Generator or connection applicant has sought and obtained AEMO’s approval to
provide an alternative model under Rule S5.2.4(c)(2), the Generator or connection applicant
must also seek and obtain approval for variations to the Data Sheets.

Notes:
1. The „R2‟ data provision is not necessary, provided that „R1‟ data is available that is derived from an off-site test that is the application of a fault, where the:
fault applied is a 2 phase-ground or 3-phase fault equivalent to what might be experienced by the generating unit installed on-site;
post-fault fault level is reasonably representative of, or lower than, the post-fault fault level that the generating unit would experience on-site (assuming all generating units of the generating system operated the same way);
generating unit tested is identical to the ones being installed on-site;
generating unit tested has identical control system settings to the ones being installed on-site, or the difference in settings can be translated into appropriate model parameter values applicable to the generating unit being installed on site; and
test and associated documentation clearly demonstrate the features and settings of the fault-ride through control system.
