Definitions
- the present invention relates to an uninterruptible power supply system, intended for sensitive equipment, supplied from the public energy distribution network and having to produce an equivalent voltage in the event of interruptions or disturbances of the public network.
- the equipment commonly encountered in the telecommunications sector is generally supplied with direct current at a voltage of 48 volts or alternating current with a voltage of 230 volts.
- This alternating voltage comes from the local electricity distribution network which is generally backed up by a generator, permanently, depending on the type of system supplied.
- the primary level is generally located in technical rooms (cellar, basement, annex rooms) distant from the equipment rooms which include the secondary level and the tertiary level.
- French patent 2,693,052 describes new generation supply chains whose operating principle uses an optimized and distributed energy technique. This technique makes it possible: - to separate the power supply and energy storage functions in "OFF LINE " type UPSs to optimize battery management in order to increase their lifespan,
- the generator sets require a starting system dedicated to the replacement source (battery, rectifier, charger).
- the present invention aims to overcome these drawbacks by proposing an Uninterruptible Power Supply system which does not include a Normal / Backup switching function between the local electrical network and the replacement source, this replacement source also respecting the environment.
- the System which continuously supplies sensitive equipment having a current supply interface is characterized in that it comprises downstream of a high / low voltage transformer station, a connection direct to at least one uninterruptible power supply (UPS) which includes batteries in parallel and a fast switching device, allowing the automatic start or start of an SR replacement source in the event of a network failure local electricity, said replacement source being coupled to said UPS batteries and delivering a direct current necessary to maintain the charge of said batteries.
- UPS uninterruptible power supply
- FIG. 1 is a block diagram of a conventional first generation supply chain
- FIG. 2 is a block diagram of a new generation supply chain comprising a power supply with distributed storage without interruption
- FIG. 3 is a block diagram of a supply chain forming the subject of the invention, comprising a Simplified Architecture Designed for the Technical Environment and Energy.
- the high / low voltage transformer station is represented by HT / BT, by GE the generator set responsible for supplying electrical energy to the installation in the event of failure of the local electrical network, by TBT N / S the technical bay also comprising the low-voltage switchboard and the Normal / Backup switching device, by RED BIE rectifiers and accumulator batteries, and by OND the power inverters.
- FIG. 2 in addition to FIG. 1, there is shown by ASI an uninterruptible power supply comprising a fast switching switch enabling the equipment, placed downstream, to be supplied without interruption from the UPS.
- SR has illustrated the replacement sources making it possible to recharge the accumulator batteries included in the UPS, the latter also being able to ensure the operation of the replacement sources.
- a downstream power supply is connected downstream of a HV / LV transformer station of a local electrical network, which is by definition unsupervised.
- the medium-term energy storage circuit of the UPS is associated with a standard conversion device (inverter) placed on standby, which is responsible for supplying uninterruptible AC voltage while waiting for start-up or supply of energy to the UPS by alternative sources.
- a standard conversion device inverter
- an "OFF-LINE" type UPS has a medium-duration energy reserve and includes a separation transformer having the objective of ensuring great safety for people and carrying out a first filtering of network parasites.
- Batteries whose voltage is in particular between 200 and 400V, ensure autonomy in the standby state, thanks to a fast contactor enabling switching between the network and the inverter.
- a direct current source coming from a replacement source SR is coupled with the batteries constituting the energy storage in the UPS.
- This direct current source maintains the charge of the UPS batteries in the event of a local power grid failure.
- the replacement sources SR are constituted in particular by turbogenerators or by fuel cells, the starting of which, in the event of a fault observed on the supply of the local electrical network, is ensured by a current from the UPS batteries. Indeed, these batteries have a high power and the launching or starting of the replacement sources SR is carried out gradually, requiring only a low intensity at startup.
- the alternator which is preferably of small diameter, is driven at a high and constant speed of rotation, thanks to the use of a turbine, and possibly at the same speed of rotation as the turbine, so as to deliver a current at high frequency, which is transformed into direct current after rectification and filtering, and which is capable of ensuring the recharging at constant voltage of the batteries of the UPS.
- a fuel cell is used as a replacement source, this comprises a certain number of elementary cells, connected in series, which deliver direct current at a high voltage which is directly usable for recharging at constant voltage the batteries integrated in there if.
- the batteries are instantly requested by the UPS in the event of a local power grid failure, so as to ensure a secure supply of the equipment connected to the UPS.
- the invention described above offers numerous advantages in terms of, on the one hand, the reduction in equipment investment costs (elimination of the low voltage switchboard TBT, of the Normal / Standby inverter, elimination of the source starting system replacement, removal of the air conditioning back-up device, removal of the inverters protecting the computer network, and secondly the improvement of operating conditions, disappearance of power outages during Normal / Backup switching, constant quality of secure power supply, homogeneous operating autonomy from a thermal and electrical point of view, improved reliability when starting replacement sources through optimized management of the batteries integrated in the UPS. integrated into the annex premises of an installation outside the operating premises, due to the distributed voltage which p from 48V (direct current) to 230V (alternating current). This arrangement makes it possible to reduce the length of the link between the UPS and the starting system.
