Objectives A desired result of this project is to help facilitate the connection of £50bn of renewable generation (25GW) onto the network, through understanding the level and impact of transient voltages that will arise from these types of connections to renewable generation and designing solutions to mitigate or neutralise their occurrence. Failure to do this could, in the worst case, lead to substation equipment failure. The ability to provide a better-informed specification could possibly result in an avoided loss of supply through damaged cables or transformer resulting in £1-2m repairs. The focus of the project will be on the Electro Magnetic Transient (EMT) modelling of components (transformers, cables, circuit breakers, instrument transformers etc. ) to provide best practice and expert opinion on their interaction with the power system. The project will: Develop component models to characterise the range of phenomena associated with transient conditions Examine the network architecture Validate EMT models in different simulation packages Disseminate the results and models to the partners
Abstract The future power system is going to be highly complex, integrating renewable generation, smart grids, voltage upgrades, increasing usage of long cables and HVDC. Successful implementation will require extensive computer simulations during all the planning and engineering phases. Existing simulation tools have limited accuracy for representing some critical components such as transformers and cables. The project will produce models that are sufficiently accurate and compatible with available circuit simulators, and make use of the models in system simulation studies in order to pinpoint bad configurations. There is also limited understanding of these interactions, such that development project and designers do not know what can cause the problems and how to avoid designing potential problems. Research The method that has been proposed for this project is as follows; Validated component models in various simulation package formats. Recommendations on component incompatibilities Set of real case studies to validate that the issues are real.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
