Looking forward in 2014 for ABB power protection - what's in store

An insight into future developments of power conditioning products.

ABB’s New Zealand–based power protection team is developing a range of medium voltage UPS products initially rated up to 6 MVA, based around the needs of customers with large sensitive and critical loads. These PCS100 MV UPS products will complement the existing range of the PCS100 LV UPS-I product and the LV double conversion products. The PCS100 MV UPS will be suitable for use in protecting critical industrial processes as seen in the semiconductor industry. The first release, scheduled for 2014, will be product rated up to 6.6 kV with even larger 15 kV class products to follow (including 11 kV and 13.2 kV options), with even higher MVA ratings.

Why MV UPS?

Figure 1The common question of “why build upon the PCS100 UPS-I?” can be simply answered by the growing need of high power usage customers to protect their critical loads from voltage events (sags and surges) and outages. Low voltage UPSs and power conditioners are widely applied, but often space constraints means fitting product in is problematic. When installed at MV voltage levels, the very compact MV UPS design can be installed in MV electrical rooms or even plant substations.

A PCS100 MV UPS can be installed into the electrical supply to protect the complete supply or alternatively just selected sensitive loads. In a data center this could include the mechanical loads. Installing the UPS protection at medium voltage provides the most energy efficient configuration as the low current at the MV level means that serious semiconductor losses are very small.

PCS100The single conversion topology used in the PCS100 UPS-I product is a natural choice for MV as losses are extremely small, meaning efficiencies well in excess of 99 percent can be achieved. Power electronics and energy storage can remain at LV, with transformer coupling to MV. Finally, the PCS100 MV UPS has many retrofit possibilities allowing custom designs to suit many applications for the higher powered industries.

Because the energy storage is kept at low voltage levels, a wide range of energy storage options will be available (flywheels, ultracapacitor, lithium Ion and high discharge sealed pb acid batteries). It is expected that ultracapacitors will be widely applied in industrial applications due to their long life and compact size. For longer autonomy applications Lithium Ion or lead acid batteries can be applied.

The PCS100 MV UPS will offer advantages such as:

  • Small footprint (compact design)
  • Retrofit possibilities
  • Highest energy efficient configuration
