Introduction: To form a new policy for substation light current systems aimed at maintaining high availability and reliability of the transmission network by balancing the whole life-cycle risk, performance and cost of assets.

To develop a new architecture for substation secondary systems by introducing new technologies, targeting a quicker and easier approach for the installation and replacement of protection and control equipment beyond 2011.

Objectives: The project has defined the following objectives.

Review of current policy and practice:

To identity and understand the whole life cycle issues for the existing protection and control systems

Strategy document for substation secondary systems:

To develop a road map to show the strategy for the application of protection and control new technology in the short, medium and long term

Feasibility Study:

To investigate new technologies
To collaborate with major suppliers/Alliances to share information
To standardise Substation primary and secondary system interface
To benchmark with leading utilities

Trials and Pilot schemes:

To try the new approach in parallel with existing systems with outputs disabled ‘Piggy-back’ trials
To apply the new approach to some real projects as pilot schemes (Min 2)

New Policy:

To develop a new policy for the substation secondary system
To develop associated technical specifications.
