A recommended practice is usually an upgrade of guidelines, and a standard is usually an upgrade of a recommended practice. The main reasons for setting guidelines, recommendations, and standards in power systems with nonsinusoidal voltages or currents are to keep disturbances to user equipment within permissible limits, to provide uniform terminology and test procedures for power quality problems, and to provide a common basis on which a wide range of engineering is referenced. There are many standards and related documents that deal with power quality issues.
The singlesource concept is still used for harmonic filter design. Power systems are usually asymmetric. This justifies the need for multiphase harmonic models and power flow that considerably complicates the simulation procedures. For more realistic cases, if more than one harmonic source is present in the power system, the single-source concept can still be used, provided that the interaction between them can be ignored. In these cases, the principle of superposition is relied on to compute the total harmonic distortion throughout the network.
