Abstract
An energy supply system adapted for supplying energy to equipment on a high voltage platform. The system includes a fuel cell and an effectuating capacitor. The system also includes an intermediate storage and supply unit. This unit stores energy from the fuel cell and supplies energy to the effectuating capacitor via an electric transforming unit. A high voltage platform including the energy supply system. An electrical network including the platform. A method for supplying energy to equipment on a high voltage platform.
Claims22
An energy supply system adapted for supplying auxiliary electric energy to an equipment on a high voltage platform along a high voltage transmission line, wherein the equipment is connected to the high voltage transmission line, the energy supply system comprising:
- at least one effectuating capacitor for supplying auxiliary electric energy to the equipment as needed,
- an intermediate storage and supply unit for recharging the effectuating capacitor when the capacitor needs to be recharged, and
- a fuel cell for recharging the intermediate storage and supply unit when the voltage across intermediate storage and supply unit decreases.
A high voltage platform a long a high voltage transmission line, wherein equipment on the high voltage platform is connected to the high voltage transmission line, the high voltage platform comprising:
- an energy supply system comprising at least one effectuating capacitor for supplying auxiliary electric energy to the equipment as needed, an intermediate storage and supply unit for recharging the effectuating capacitor when the capacitor needs to be recharged, and a fuel cell for recharging the intermediate storage and supply unit when the voltage across intermediate storage and supply unit decreases.
An electrical network, comprising:
- at least one high voltage platform a long a high voltage transmission line, wherein equipment on the high voltage platform is connected to the high voltage transmission line, the high voltage platform comprising an energy supply system comprising at least one effectuating capacitor for supplying auxiliary electric energy to the equipment as needed, an intermediate storage and supply unit for recharging the effectuating capacitor when the capacitor needs to be recharged, and a fuel cell for recharging the intermediate storage and supply unit when the voltage across intermediate storage and supply unit decreases.
A method for providing auxiliary electric energy to an equipment on a high voltage platform along a high voltage equipment line, wherein the equipment is connected to the high voltage transmission line, the method comprising repeatedly:
- supplying energy from a fuel cell to an intermediate storage and supply unit when a voltage across the intermediate storage and supply unit decreases,
- supplying energy to the equipment from at least one effectuating capacitor if needed, and
- recharging the effectuating capacitor by supplying energy from the intermediate storage and supply unit when the capacitor has to be recharged.
