B5 Protection and automation
Purpose
To facilitate and promote international advancements in engineering, exchange of information, and expansion of knowledge in the field of protection and automation, focused on protection, control, monitoring, metering and fault locating, and aims to cover the whole power system, from transmission, to distribution systems, including generation. To add value to this information and knowledge by means of synthesizing state-of-the-art practices, identifying and evaluating technological and functional evolutions and developing recommendations.
Study Committee B5 covers power system protection, substation control and automation, fault location, remote control systems and equipment, metering systems and equipment.
Within its technical field of activity, Study Committee B5 addresses topics throughout the protection, control, monitoring, metering, and fault locating devices and systems management life-cycle phases; from conception, through research, development, design, engineering, configuration, production, deployment, operation, and end-of life. At all stages, technical, safety interactions with, and integration into, the evolving power system and the operating environment are addressed. All aspects of performance, specification, testing and the application of testing techniques are within scope, with a specific focus on the impact of changing interactions and demands due to technology evolution and changing the power systems. Life cycle assessment techniques, risk management techniques, education and training are also included.
