ABB has launched its line voltage regulator (LVR) product family for distribution networks that will help increase the reliability as grids receive more electricity from renewable energy installations.
The line voltage regulator is designed to help manage variations in voltage levels and adjust the voltage accordingly. ABB offers line voltage regulators for medium-voltage (MV) and for low-voltage (LV) grids. The MV regulator is available for ratings up to 8 Mega Volt Ampere (MVA) and the LV regulator for ratings up to 250 Kilo Volt Ampere (kVA), and both allow the voltage to be adjusted by up to +/-10%. ABB developed the LVR in conjunction with Germany’s “Networks of the future/Smart Country” initiative. It has worked with the German utility RWE AG to test it on distribution grids in Germany, as well as separately in Switzerland where since 2014 it has been successfully smoothing out the typical voltage fluctuations generated by a solar power station in a rural area.
