摘要

Converting existing synchronous units into variable speed is an expedient and cost-effective solution to increase power regulation capabilities for plant operators. It also facilitates the integration of intermittent renewable energy generation into the electrical grid. However, some constraints and limitations must be fully assessed before such a conversion may be undertaken. Constraints coming from civil structures or the hydraulic circuit would be the most difficult and most costly to overcome. EDF and Alstom, based on their respective experience in pumped-storage plant design and operation, have made such an assessment in order to upgrade a 270 MVA existing unit into a 300 MVA variable speed machine.
