A wide range of electric loads, has functional concepts hat lie outside the common standards (resistive, inductive, capacitive), as, for instance: gas-discharge lamps, or electronic loads; in fact, for their own functional features, these loads, introduce some harmonic distortions on the absorbed current, that cannot be solved with normal compensating systems (as, for example, phase advancers). A disadvantage which affects the feeders and their respective generators, therefore reducing: their efficiency, the power capacitance that can be supplied, and the qualitative level of energy distribution. Our system succeeds in evaluating and compensating (for the part of energy that its power section allows), the harmonic distortion on the network, therefore improving the various parameters which characterize it. Besides, since the system can operate both as load and as generator, it can be structured so that it uses the power sections, already useful to hold other applications; and that greatly reduces the price-of-the-device/corrected-power ratio. |
