| Objectives | The project intends to explore and trial the use of the SuperTapp SG relay currently installed at the majority of ENWs 11kV primary substations – ENWs standard AVC relay and which has already demonstrated its capability to provide frequency-based responses - to provide a more granular LFDD service, thereby reducing the size of any individual load block. In addition, by using the relays in conjunction with additional network monitoring and measuring equipment, the direction of the power flows at a substation could be taken into account through a dynamic approach to providing LFDD, allowing sites which are net exporters to remain connected. The project will carry out the following:Design and test firmware updates for the SuperTAPP SG relays to allow provision of the LFDD functionDesign a number of variations of LFDD schemes around the relay that takes levels of generation into accountCarry out a set of test installations at a number of Electricity North West primariesTest the functionality of the relays in situ, using methods which do not put customers at risk, i.e. using accepted protection testing methods such as secondary injection with the trip links removedCarry out a desktop study to show the costs and benefits of rolling out this approach network wideInvestigate the possibility of using a centralized LFDD response scheduler application to adjust the number of sites required for each LFDD block, including consideration of how these adjustments might be made Demonstrate the ability of the relay to provide a LFDD response that complies with required standards for operationIdentify a scheme design that provides the appropriate response whilst accounting for power flowsTest this scheme on real world installations at around six primary substations fed from a common BSP and which have high levels of connected generation.Identify future possible improvements to the scheme and a next phase of this project | |
