ABB launches more efficient LVRs for low, medium voltage

By Editor


Switzerland-based ABB has launched a new line voltage regulator (LVR) series that can facilitate the integration of renewable power with the grid more efficiently.

The systems meant for distribution networks will help manage the fluctuations caused by renewable energy entering the mix more efficiently.

According to a report, the LVRs, designed in conjunction with Germany’s ‘Networks of the future/Smart Country’ initiative, are designed to manage variations in supply and maintain voltage accordingly.

ABB’s LVRs are available for medium-voltage (up to 8 MVA rating) and for low-voltage (250 kVA rating) grids. The systems allow voltage to be adjusted by up to +/-10 percent.

ABB power products division president Bernhard Jucker said: “This latest line voltage regulator can automatically adjust the voltage based on the actual load or generation mix in the distribution system, addressing a key stability challenge posed by the increasing amount of renewables entering the power network.

“It can make an important contribution in the evolution of smarter and greener grids. This development addresses the dynamics of the evolving power grid.”

Earlier this month, ABB entered a deal with Rampion Offshore Wind Farm to supply substations and related power infrastructure.

As part of the deal, ABB is to provide power infrastructure for the offshore platform as well as the onshore substation to integrate the new wind farm into UK’s transmission grid.

ABB had stated that it was to equip the onshore substation with four STATCOM (static compensator) units to ensure grid stability.

The 400-MW project is being developed by energy company E.ON, in partnership with the UK Green Investment Bank (GIB).

ABB was responsible for the turnkey delivery of the onshore substation, including high-voltage air-insulated switchgear (AIS), gas-insulated switchgear (GIS), transformers and substation automation as well as control and protection systems.

ABB will supply medium-voltage switchgear, power transformers and protection and control systems for the offshore platform as well as two new switchgear bays with control and protection equipment for the National Grid’s nearby substation at Bolney, receiving power from the new wind farm, a report stated.
