Minimization of reactive power under nonsinusoidal conditions

The author extends his earlier paper `Considerations on reactive power in nonsinusoidal situations´ (see ibid., vol.IM-34, no.3, p.399-404, 1985) to compensation issues. IT is shown that the shunt LC compensator can minimize the reactive power of an RL load only if one of its parameters, L or C is fixed. A method of capacitance calculation is presented and it is shown that the inductance choice affects the harmonic suppression. The complexity of a compensator for the total compensation of reactive power is calculated and a method of synthesizing such a compensator is presented.
