Abstract Power quality(PQ) assessment has become one of the main concerned problems of PQ researches. The definition of custom assessment and public assessment of PQ are presented for the need of power customers. The relationships of single assessment, comprehensive assessment, sites assessment, system assessment, planning assessment, compatibility assessment, quantifying assessment, qualitative assessment, custom assessment and public assessment of PQ are analyzed. Based on these, an infrastructure of PQ assessment system (PQASI) is built from two different views. It has two layers. On the technology layer PQ assessment can be made according to quality contents, net circumstances, and forms of outcomes. The results of assessments on the technology layer can be mirrored to the application layer, which face the entities of electricity market, utilities and power customers.
