Introduction to Power Quality from Power Conditioning


This chapter begins with an introduction to the concept of power quality, which has developed into a discipline that defines the reference parameters for assessing the suitability of the waveforms of voltage and current of an electrical system, so allowing compatible operation of all equipment that constitutes that system. Different standards set limits on the allowed disturbances of voltage and current source. Some disturbances that occur in an electrical network are due to the presence of nonlinear loads. A model based on the equivalent Norton of a load is presented, in order to develop a theoretical analysis of the system when this load type is present. Furthermore, an update ...
