ECOTAP VPD FOR PUBLIC DISTRIBUTION GRIDS


For almost 100 years, the high-speed resistor-type tap-changer principle on which the new ECOTAP VPD is based has been a proven way of compensating for voltage fluctuations in the high-voltage grid and supergrid. MR has the longest operating experience in regard to such equipment. With the ECOTAP VPD we can now transfer this principle to the medium-voltage level and open up new possibilities for distribution grid operators. ECOTAP VPD allows voltage fluctuations in volatile grids to be compensated for easily and in a matter of seconds. Thanks to ECOTAP VPD, renewable energies and new forms of demand can be economically integrated into the grid, making elaborate and expensive grid reinforcement unnecessary. And finally, ECOTAP VPD helps to improve the efficiency of grid sections, optimize grid topologies, and if necessary even reduce the number of secondary substations needed.

 

Maintaining a stable voltage is a major challenge for many public distribution grid operators. In wide ranging grids with overhead cables, a weak short-circuit capacity, and huge increases in demand, as are commonly found in Asia and Africa, it is very hard to ensure a stable voltage supply. This is especially true if the upstream grid operator does nothing or very little to ensure voltage stability.

COMPLETE VOLTAGE CONTROL FOR DISTRIBUTION GRID OPERATORS

Using voltage regulation transformers with ECOTAP VPD, distribution network operators have direct access to tried-and-tested equipment, which they can use at a central location to stabilize the voltage for several low-voltage outputs regardless of the voltage in the upstream network. Compared with banks of capacitors, voltage regulation transformers have a longer operating life and permit finer regulation. They are also more economical than line regulators because they can stabilize a larger grid area.

Distribution grid operators face a difficult balancing act: On the one hand, they need to ensure a stable supply voltage in the medium and low-voltage grid and on the other hand, they need to integrate a growing amount of renewable energy (increase in voltage) and in the future also new types of demand (decrease in voltage). As a result, distribution grid operators see themselves forced into expensive grid expansion measures, even though the thermal capacities of their equipment in the grid are far from being fully exploited.

MAKING OPTIMUM USE OF GRID CAPACITY WITH VOLTAGE REGULATION DISTRIBUTION TRANSFORMERS.

A voltage regulation distribution transformer, i.e. a distribution transformer with ECOTAP VPD in-tank small, solves the crux of the problem – maintaining the voltage band – by dynamically adapting the voltage. The available voltage band can be re-distributed and therefore used more effectively.

Currently, this principle is primarily used to connect renewable energies; however, it can also be used to integrate additional demand into the existing grid.

Because this can increase the grid's ability to absorb voltage by up to a factor of 4, expensive grid expansion can usually be completely avoided or at least put on hold. First and foremost, the voltage regulation distribution transformer can be used to make greater and therefore more economic use of grid equipment.

An efficient distribution grid has as little equipment as possible. This enables savings of both acquisition as well as maintenance costs. Voltage regulation distribution transformers with ECOTAP VPD help to improve the efficiency of grid sections. Using them can reduce the total number of distribution stations.

This results in many potential savings, for example for rent, maintenance and servicing of the stations, as well as for investments in replacements or new equipment. The only requirement is that one transformer is configured such that its performance is sufficient for the load and/or feed-in of the enlarged grid area.
