Numerical simulations for energy calculation in power measurements

Measurements limitations of the reactive power flow in the power systems have represented, since the early stage of the processes of high voltage networks design, construction and operation, an important issue for the specialists. This paper analyses the most used competitive definitions for the reactive power, implemented in digital energy meters, and compares the most usual measuring methods used in reactive energy measurement. Numerical simulations of the measurement techniques provide an error based evaluation of performances.
