VARIABLE SPEED DRIVE ARRANGEMENT |
| 摘要 |
A variable speed drive arrangement including: a load; a gearbox to supply mechanical drive to the load; a converter electrically coupled with a power grid. Also a primary electrical machine to supply mechanical power to the gearbox and to receive electrical power; and a secondary electrical machine mechanically coupled to the gearbox and electrically coupled to the converter. An electrical circuit breaker to selectively electrically couple the primary electrical machine to the secondary electrical machine or to the power grid; wherein the secondary electrical machine is adapted to supply or extract mechanical energy from the gearbox and to receive or deliver electrical energy to the converter. Also a control method for the arrangement including a starting mode and a running mode. |

1. A variable speed drive arrangement comprising:
a load; a gearbox to supply mechanical drive to the load; a converter electrically coupled with a power grid; a primary electrical machine to supply mechanical power to the gearbox and to receive electrical power; a secondary electrical machine mechanically coupled to the gearbox and electrically coupled to the converter; and a first electrical circuit breaker to selectively electrically couple the primary electrical machine to the secondary electrical machine or to the power grid; wherein the secondary electrical machine is adapted to supply or extract mechanical power from the gearbox and to receive or deliver electrical power to the converter. |
