Objectives To address the above problem this project will carry out research into hardware and software architectures and technologies that will enable the virtualisation and centralisation of substation protection automation and control functions and enable all functions to be hosted on a common real time hardware platform. Based on the findings, the requirements for hardware and software components will be defined such that the system can meet the requirements of a transmission substation in terms of performance, scalability, security, dependability and cyber security requirements. The requirements will be documented and will provide the specification for a proof of concept prototype implementation of such a system. A detailed test plan will be developed to validate the performance of the system. Apart from the above technical aspects the project will also investigate the economic aspect of this technology, i.e. better protection of investment into software through platform independence, investigation of open source solutions and the creation of an open source ecosystem providing opportunities to reduce and share development cost.Data Quality Statement (DQS):​The project will be delivered under the NIA framework in line with OFGEM, ENA and NGGT / NGET internal policy. Data produced as part of this project will be subject to quality assurance to ensure that the information produced with each deliverable is accurate to the best of our knowledge and sources of information are appropriately documented. All deliverables and project outputs will be stored on our internal sharepoint platform ensuring access control, backup and version management. Relevant project documentation and reports will also be made available on the ENA Smarter Networks Portal and dissemination material will be shared with the relevant stakeholders. Measurement Quality Statement (MQS): ​The methodology used in this project will be subject to our suppliers own quality assurance regime. Quality assurance processes and the source of data, measurement processes and equipment as well as data processing will be clearly documented and verifiable. The measurements, designs and economic assessments will also be clearly documented in the relevant deliverables and final project report and will be made available for review. In line with the ENAs ENIP document, the risk rating is scored 6 = low.TRL Steps = 1 (2 TRL steps)Cost = 3 (>£1M)Suppliers = 1 (1 supplier)Data Assumption = 1 (clearly defined assumptions and principles) The scope of the project covers 3 phases. The first part of the project will focus on research and optioneering. Suitable technologies and innovative HW and SW architectures will be investigated with regards to their potential to be developed into a system that can deliver all PAC functions for a transmission substation. Capabilities and requirements with regards to performance, environmental and cyber security will be investigated. Standardisation, portability and interoperability will be some of the key principles used during development and evaluation of potential concepts. The key findings and options will be reported as part of the first phase of the project.Based on the findings in phase 1, phase 2 of this project will deliver a review of available options and design optimisation in order to provide a requirements and design specification for a centralised PAC solution. The work will also cover lifecycle management for such solutions including the engineering process, design, delivery, maintenance and replacement. As part of the delivery, testing of such systems will be essential and in particular the interaction between software and hardware resources as the systems are scaled up for large substations. The methodology for testing will consider scalability as well as interoperability.The final phase of the project will use the requirements specification and build a (small scale) proof of concept demonstrator that complies with these requirements and principles outlined in the project. The test plan developed in phase 2 will be used to evaluate the performance of the demonstrator. Based on the learning from the project an updated assessment of potential benefits to consumers and energy networks is also included in the work. The objective of this project is to develop the technologies required for centralised protection, automation and control systems in transmission substations. This includes research into software and hardware platforms and architectures interacting with a digital substation process bus network. The project aims at delivering a state of the art of current capabilities in this area and developments in the near future concerning virtualisation of functions and real time hardware platforms suitable for centralised PAC. New and emerging technologies will also be investigated. The solutions need to allow virtualisation of substation functions and allow portability between platforms to enable separate management of software and hardware lifecycles. Based on the findings a requirements specification and functional design specification will be produced. The project will also aim to develop the engineering, design, delivery, maintenance and replacement methodology in order to cover the full life cycle of centralised PAC systems. Specifically testing and commissioning requirements and plans will be developed. Based on these outputs the project will develop, build and test a reduced scale proof of concept system that can demonstrate the required functionality and performance.
Abstract The capability and versatility of protection hardware platforms has significantly increased over recent years opening opportunities for more centralisation and virtualisation of functions. This has been recognised and preparations for future standards, requirements are currently in preparation as part of CIGRE working groups and current innovation projects. The proposed solution aims to take the next step in this development by delivering a demonstrator for a centralised substation platform. The solution will consist of Merging Units, process bus network and centralised PAC platform.The project will include an assessment of current HW capability, SW architectures, development of specifications and requirements for scalable, open, cyber secure transmission substation solution, test methodology and a demonstrator for laboratory-based evaluation
