A UNIVERSAL COMPENSATOR FOR POWER QUALITY IMPROVEMENT IN LV DISTRIBUTION GRIDS

A Universal Compensator (UC) for Power Quality improvement is presented in the paper. It can compensate harmonic currents, reactive power and unbalances of disturbing loads and supply in island mode sensitive loads. In case of grid disturbances, a static switch is open and the UC restores the voltages before disturbance occurrence at the load connection point. A 50 kVA UC model has been designed and a digital simulation model is used to assess its performances. Simulation results of compensation of different type of loads are reported both for grid connected and island operations.
