Assessment on apparent power indices with hybrid active power filters

2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2017
This paper presents a method for assessing the quality improvement of the electric power, when compensation equipment based on hybrid active power filters is applied. Power quality indicators that allow to separate the contribution to unbalance of each harmonic and interharmonic of voltages and currents are introduced, calculated with an enhanced ...
