Reliability Analysis and Design Guidelines for LV AC Auxiliary Systems

This article is a summary of the activates of CIGRE WG B3.42 (Reliability analysis and design guidelines for LV AC/DC Auxiliary Systems). The group produces two technical brochures on the LV AC auxiliary system and LV DC auxiliary system respectively. In this technical brochure (TB) on the LV AC auxiliary system, we primarily focus on the AC auxiliary system in substations, converter stations, thermal power plants and hydropower plants.

Substations and electrical installations

This Technical Brochure has been created by a Working Group from the CIGRE Substations and electrical installations Study Committee which is one of CIGRE's 16 domains of work.
Study Committee B3 addresses a wide range of topics that are applicable to the entire life-cycle of substation assets; from conception, through research, development, design, production, deployment, maintenance, operation, and finally, end-of life and disposal. Our activities address all stages of asset life and include not only technical aspects but also safety, economic, environmental and social aspects. All issues of performance, specification, testing, monitoring and the application of diagnostic testing techniques are within scope, with a specific focus on the impact of changing demands for substations due to continued evolution of the power system. Safety and life cycle condition assessment techniques, health indexing, risk management techniques, education and training are also important topics for our work.
