Impact of Cycling on Large Electrical Motors

Conventional power plants in many parts of the world are increasingly required to operate flexibly to facilitate both larger penetration of renewable energy and commercial considerations of operating in peak demand periods. Cyclic operation including two-shifting, operating at minimum load, and fast ramp up/down have all become normal for many power plants, even from quite an early stage of plant life. Operational flexibility is crucial for the commercial success of power plants.

Power generation and electromechanical energy conversion

This Technical Brochure has been created by a Working Group from the CIGRE Power generation and electromechanical energy conversion Study Committee which is one of CIGRE's 16 domains of work.
The SC covers all aspects of electromechanical energy conversion equipment, rotating electrical machines for power generation, grid support, and energy conversion within industrial applications. This includes research, development, design, manufacture and testing of power generation and electromechanical energy conversion equipment and their associated auxiliaries, commissioning, operation, condition assessment, maintenance, life extension, refurbishment, upgrades, efficiency improvement, conversion, storage and de-commissioning.
