CIGRE B1 - Composition 3 Advisory Groups 18 Working Groups 2 preparatory Task Forces 4 Joint Working Groups with participation of 535 experts. 2020 Virtual Study Committee Update Meeting November 6
Highlights of SC B1 Study Committee (SC) B1 is responsible for AC and DC insulated power cable systems for power transmission, Distribution and generation connections on land and in submarine applications, As well as for power cable systems associated with micro-grids and the integration of distributed resources. Within its technical field of activity, Study Committee B1 addresses theory, design, applications, manufacture, installation, testing, operation, maintenance and diagnostic techniques 2020 Virtual Study Committee Update Meeting November 6
Highlights of SC B1 SC B1 is also engaged to actively follow the four strategic directions given by the Cigr Technical Committee. Thus paying attention: to prepare the electrical power system of the future, to make the best use of existing system, focusing on environment and sustainability and communication on power system issues for decision makers. Power Systems of the Future and Best Use of Existing Systems remain the main focus of most of the work. Newly discussed topics are often around environmental and sustainability aspects. 2020 Virtual Study Committee Update Meeting November 6
STUDY COMMITTEE SC B1 Preferential Subjects PS 1 : Learning from experiences Design, manufacturing, installation techniques, maintenance and operation Quality, monitoring, condition assessment, diagnostic testing, fault location, upgrading and uprating methodologies and relevant management Lessons learnt from permitting, consent and implementation PS 2 : Future functionalities and applications Innovative cables and systems, exploring the limits Role and requirements of power cables in tomorrow s grids Prospective impacts from the Internet of Things, Big Data and Industry 4.0 on power cable systems PS 3: Towards sustainability Environmental challenges impacting current, planned and future cable systems Safety considerations, cyber and physical security, including case studies Projects and initiatives to promote access to affordable, reliable, sustainable distribution and transmission cable lines for all 2020 Virtual Study Committee Update Meeting November 6
