Abstract
A new methodology for the definition and measurement of non-active power in electrical networks operating under non-sinusoidal conditions is proposed; it operates in the time-domain through decomposition of vectors representative of electrical quantities, characterizing the generic load, in an n-dimensional space. After a brief summary of the concepts connected with the definiton of apparent power under sinusoldal conditions, the main theories which have been proposed up to now about the definition of non-active powers, under non-sinusoidal conditions, are examined. Afterwards proof of the flexibility of the new technique is given as regards the identification of the parameters of the compensation network, capable of increasing the value of the load power factor up to the maximum possible. Different configurations have been considered, from the simple capacitor or reactor to more complex ones, gaining always a considerable amount of information about the parameters of the compensation network permitting one to attain in the best way the objective of optimization of the load power factor.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
