Customer expectations on Power Quality are growing and they are expecting a clean source of power from their suppliers for their increasingly sensitive process. In order to maintain a clean voltage supply, the utilities are forced to implement regulations that oblige end-users to compensate disturbing loads. This paper will demonstrate the application of a Hybrid Var Compensator (HVC) designed to mitigate flicker produced by a car shredder. The HVC system is composed of an active harmonic

... (AHF) that will operate in electronic var compensation (EVC) mode injecting in real time lagging and leading reactive power, installed in parallel with a detuned capacitor bank. This solution allows the customer to be connected to the grid and meet the utility flicker regulation. In addition, this also allows the utility to guarantee a clean source of power to their other existing customers.
