Objectives The objectives of the work is as follows: Improve accuracy and detail of information available on the condition of the HVDC networks Increase ability to carry out preventative maintenance Reduce the number of cable and insulation failures and as a result the outages and downtime Allow more accurate determination of where the faults in the cables have occurred and thus reduce costs of repairs. This project will be deemed successful if the maintenance costs can be reduced and the reliability of the supply of electricity increased so as to reduce the cost and for UK consumers and the quantity of maintenance trips required.
Abstract High Voltage Direct Current (HVDC) subsea export cables and interconnectors are critical to the development of a European electricity transmission “supergrid”. The proposed Round 3 large UK offshore wind farm installations (including the four largest at Dogger Bank - 9. 0GW, Norfolk - 7. 2GW, Irish Sea -4. 2GW and Hornsea - 4. 0GW) will add up to 25GW to the 8GW of offshore wind power that the Rounds 1 and 2 will provide. The big difference with the larger Round 3 wind farms is that due to the cost of high AC transmission losses to their more remote locations, they will all look to use offshore HVAC/DC substations and HVDC export cables back to land over the longer distances involved (of 100km+). The UK Government (DECC) have stated that they require the (presently high) operational and maintenance costs to fall by 25% by 2020 to make this offshore renewable electricity more affordable to the UK consumer. At present the service reliability and the accuracy and detail of the state, condition and performance of the HV networks is not satisfactory. As a result the operating and maintenance costs are too high to allow this source of renewable energy to meet the DECC targets. To address the market need for improved maintenance information HPVD and our partners are developing an integrated high voltage network management system (OLPD-HVDC) that will address the emerging industry demand for the holistic condition monitoring of these critical subsea HVDC cable networks. The system will provide early warning of faults and therefore allow direct preventative maintenance to help improve operating efficiency through the use of holistic condition monitoring (CM) technology solutions and a corresponding, robust condition based management (CBM) approach to managing these assets. The monitoring technology will be able to indicate insulation defects along with cable faults ahead of failure to allow for preventative maintenance interventions. This will prevent the need for unplanned outages and downtime which as a result improves the security of supply and reduces operation and maintenance costs.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
