Electrical power network pollution estimation

This work addresses the estimation of electrical power network polluting agents, extending the discrete harmonic polluting case to a larger framework, including a broader class of electric signal deformation. Similar to the harmonic estimation procedure, the power network is modeled such as to include extra monitoring ports. These ports delimit a linear network, except for the pollution injection points. Proper port location allows estimating current injections in nonmeasured internal network nodes. In an illustrative case, the method is applied to a variety of polluting injected waveforms, indicating close match between real and estimated signals.
