project agreement for the above committed project is reached. It is envisaged under the

Infrastructure Agreement that the TSO will issue a committed project parameter (CPP) to the

TAO. The TAO will develop a project implementation plan (PIP) from this CPP and submit to

the TSO for approval. Once the CPP is finalised and the PIP is determined or agreed to be

satisfactory, then the Project Agreement shall be prepared.

1.2.4 220 KV REMOTE S TATION WORKS

1.2.4.1 B ALLYVOUSKILL 220 KV S TATION

The protection requirements associated with the Ballynahulla 220kV bay (previously known

as the Kiskeam 220kV) at Ballyvouskill 220kV station have been specified as part of CP0650

and should not be scoped as part of this project.

1.2.4.2 K NOCKANURE 220 KV S TATION

The protection requirements associated with the Ballynahulla 220kV bay (previously known

as the Kiskeam 220kV) at Knockanure 220kV station have been specified as part of CP0500

and should not be scoped as part of this project.

1.2.5 110 KV REMOTE S TATION WORKS

The protection requirements associated with the Ballynahulla 110kV bay at Cordal 110kVstation will be catered for under a separate CPP and should not be scoped as part of this

project.

1.3 220 KV & 110 KV CIRCUIT DESIGN

1.3.1 220 KV OHL DESIGN

The station is to loop in to the existing Clashavoon – Tarbert 220kV circuit. This will result in

two new 220kV circuits;

• Ballynahulla - Ballyvouskill 220kV station

• Ballynahulla – Knockanure 220kV station

This will require the installation of two 220/110kV line interface towers.

1.3.2 220 KV & 110 KV C ABLE DESIGN

The 220kV connections to the new Ballynahulla 220/110kV GIS station will occur by means of

underground cable.

The 220kV cables required as part of this project are to have a rating equivalent to 600mm 2

HTLS conductor at 80 0C. This is due to the uprate of the Clashavoon Tarbert 220kV line as

part of CP0763. The line will be uprated from 600mm 2 ACSR @ 80 0C to a rating consistent

with 600mm 2 HTLS conductor at 80 0

A 110kV cable circuit to the new Cordal station is required to be installed as part of this

Title: Protection Requirements for Ballynahulla 220 kV / 110 kV Transmission StationCPP: CP0651Revision: 1.7Date: 07/03/2014

1. Summary

Ballynahulla is a new 220 / 110 kV transmission station that will be constructed along the path ofthe existing Clashavoon – Tarbert 220 kV line.

This specification is based on the SLD XDN-SLD-CP0651-F-BYH-001. Rev05

The following is assumed for Ballynahulla 220 kV GIS busbar:

220 kV GIS double busbarOne 220 kV transformer bay T2102 (250 MVA)Two 220 kV line bays (Ballyvouskill and Knockanure)One spare 220 kV transformer bayFour spare 220 kV line baysTwo 220 kV wing coupler bays (K1 and K2)Two 220 kV sectionalising circuit breaker bays (SA1-2 and SB1-2)

The following is assumed for Ballynahulla 110 kV GIS busbar:

110 kV GIS double busbarOne110 kV transformer bays T2102 (250 MVA)One spare 110 kV transformer bayOne110 kV line bay (Cordal)Five spare 110 kV line baysTwo 110 kV wing coupler bays (K1 and K2)Two 110 kV sectionalising circuit breaker bays (SA1-2 and SB1-2)

It is assumed that the new station will be equipped with a SCS as per the current term contract.The protection for the spare bays will not be specified as part of this project.

2. Ballynahulla Protection Communications Requirements:

The protection at Ballynahulla will require access to the fibre network for Differentialcommunications and for Impedance protection teleprotection signalling. As access to thefibre network in this region is limited, the communication requirements, as outlined in thefollowing sections, must be given consideration at the earliest point in the design process.

3. Ballynahulla Protection Relay Requirements:

The GRL100 relays for this station have been specified with the additional backup distanceprotection function to cater for the phased provisioning of FO based protectioncommunications. The communications infrastructure in this region will be built as part of theBallyvouskill, Kilpaddoge, Knockanure and Ballynahulla projects. As the timeline for thecompletion of each project is not clearly defined at this stage, the backup distance function inthe GRL will allow the lines to be operated with duplicate impedance protection until such timeas the communications infrastructure is completed. A modified protection elementary will berequired for these relays and must be requested at the earliest possible stage in the designprocess.

4. Ballynahulla Bus Zone / Circuit Breaker Failure Protection:

4.1. Install a combined BZP/CBF scheme for the new 220 kV busbar. The scheme must bespecified to cater for the initial development of the busbar and have adequatecapacity for any future bays.

4.2. A 220 kV Bus Zone Protection trip should block local auto-reclosing and initiatetransmission of PTT and auto-recloser block signals to the relevant remote stations (2second signal duration).

4.3. Stage 1 operation of the 220 kV circuit breaker fail protection scheme should result in:o Attempted triple pole tripping (trip commands to both sets of trip coils) of the

failed CBo The blocking of the local auto-recloser (Line Bays only)o The transmission of PTT and auto-recloser block signals to the remote end (2

second signal duration)4.4. Install a combined BZP/CBF scheme for the new 110 kV busbar. The scheme must be

specified and designed to cater for the initial development of the busbar and for anyfuture bays.

4.5. A 110 kV Bus Zone Protection trip should block local auto-reclosing and initiatetransmission of PTT and auto-recloser block signals to the relevant remote stations (2second signal duration).

4.6. Stage 1 operation of the 110 kV circuit breaker fail protection scheme should result in:o Attempted triple pole tripping (trip commands to both sets of trip coils) of the

failed CBo The blocking of the local auto-recloser (Line Bays only)o The transmission of PTT and auto-recloser block signals to the remote end (2

second signal duration)

5.5.3. The SCS should provide a facility to locally select “Control Sync” mode. 5.5.4. The CB to be “Control Sync” closed should be selectable locally via the SCS HMI.5.5.5. When a CB has been s elected for “Control Sync” the SCS shall:
