1) Modelling TCSC with detailed control and protection systems in RTDS

The aim of this work package is to build the detailed FACTS device model in RTDS. The model will be represented in close to the practical TCSC from National Grid’s Hutton project.

2) Power system performance studies of the detailed FACTS-integrated power network

The aim of this work package is to evaluate the performance FACTS-integrated network in steady-state and dynamic conditions for identification of potential risks in terms of control system and develop effective method(s) to manage those risks.

3) Testing protective relays in RTDS-based closed-loop testing platform

The aim of this work package is to test the performance of physical protective relays for the FACTS-integrated and adjacent circuits for identification of potential risks in terms of protection system and develop effective method(s) to manage those risks. The simulation results from Package 2 & 3 will be validated against real data from Hutton project.

For National Grid (and other utilities), to develop a new independent methodology which can be repeatedly and effectively applied to assess: 1) the impact on P&C systems for future applications of power electronic devices; 2) post-delivery circumstances in the future when the networks adjacent to existing power electronic devices change as a result of customer behaviour (e.g. new generation or demand applications).   

In general, a successful project will see a cost-effective methodology being established to assess the impact of power electronic devices on the performance of existing P&C systems of power networks and to reduce the associated risks as well as see in-house skills and capabilities being developed to understand and manage P&C systems for future complex network conditions which involves power electronics devices.

According to Scope of Work, three specified work packages need to be completed on time with key deliverables as follows:

  1. Project progress report for WP1 (Feb, 2016)

  2. Project progress report for WP2 (Aug, 2016)

  3. Project progress report for WP3 (Feb, 2017)
