Definitions
- the invention relates to an arrangement for compensating for voltage drops in a power supply network and to methods for compensating voltage drops in one
- Voltage dips in power supply systems usually occur more or less regularly due to natural causes. For example, this weather situations, a bird ⁇ impact or other external influences can be. These events are typically short-lived, typically 50 ms to several 100 ms, and may result in short interruptions of typically up to 300 ms or longer interruptions of up to 3 minutes or longer.
- the depth of the voltage drop can vary between 20% and 100%, wherein the voltage dip can occur in one pole or Mopo ⁇ lig.
- These very short dips in the power supply often lead to disruptions in systems such as manufacturing or process equipment. For example, a robot controller or the like can fail, which can sometimes cause considerable financial damage.
- UPS fast uninterrupted ⁇ uninterruptible power supplies
- they have, for example large, fast uninterrupted ⁇ uninterruptible power supplies (UPS), but typically primarily in a complete power failure einsprin ⁇ gen.
- UPS fast uninterrupted ⁇ uninterruptible power supplies
- they describe known voltage Stabilizers like "Dynamic Voltage Restorer (DVR)."
- DVR Dynamic Voltage Restorer
- Dynamic Voltage Restorer voltage stabilizers are limited in the treatment of fault type, duration and performance and therefore can only handle a fraction of all errors. How big this proportion is depends on the local conditions. For example, Dynamic Voltage Restorer voltage stabilizers can only compensate for voltage drops of up to approx. 40% residual voltage. Egg ⁇ ne interruption of the power supply can not be compen ⁇ Siert. Likewise, an active power can not be transmitted.
- Network feed system are transferred.
- the first converter system and the second converter system are each designed as a DC / AC converter system.
- the distribution is designed as a mean voltage distribution.
- the coupling of the insects in a fault in the first or second power supply, the dung OF INVENTION ⁇ proper arrangement can support the voltage.
- the first switch in a first system ⁇ state is closed and the second shawl ⁇ ter.
- the first switch in a second system ⁇ state is open and the second switch is closed.

- the arrangement 100 includes a first power supply ⁇ 201 and a second power supply 202, deswei- direct at least one first converter system 301 and a two ⁇ tes converter system 302, the intermediate circuits are coupled, and thus form a network coupling 300th
- the first grid feed 201 is connected to a distribution 800 via a decoupling loop 400, a voltage measurement 500 and a first switch 601.
- the second power I ⁇ supply 202 is connected via a second switch 602 with the comparison Division 800 connected.
- Parallel to the second switch 602 at the second power supply 202, the network coupling 300 is arranged on ⁇ .
- a first converter switch 351 and a second converter switch 352 are provided for disconnecting the mains coupling 300.
- this is connected to the distribution 800 via a first converter transformer 361 and the first converter switch 351.
- the second analog converter system 302 is connected via a second converter transformer 362 and the second convergence ⁇ ter-switch 352 with the second power supply 202 verbun ⁇ .
- the first converter system 301 and the second converter ⁇ system 302 may each be a DC / AC converter system.
- the distribution 800 may be formed as a medium voltage distribution.
- FIG. 2 shows the arrangement 100 according to the invention from FIG. 1, wherein the coupling of the intermediate circuits comprises battery systems 371, 372. These battery systems allow for a simultaneous failure of the first power I ⁇ supply 201 and the second power supply 202, the voltage can be supported on the distribution 800th
- the arrangement 100 illustrated in Figures 1 and 2 befin ⁇ det located in a first system state if the first shawl ⁇ ter 601 is closed and the second switch is open 602nd This first system state is the normal state.
- the first grid feed 201 is responsible for the power supply of the distribution 800.
- the second power supply 202 In the event that the first power supply breaks 201 or fails, the second power supply 202 to take over the chip ⁇ voltage supply distribution 800th In this second system state, the first switch 601 is open, whereby the first grid feed 201 is disconnected from the distribution 800, and the second switch 602 is closed.
