英文摘要： To research the power quality emission levels and characteristics of typical load and achieve high power quality of power supply, is not only a key link in the process of comprehensively improving the reliability of distribution network, but also the technical difficulties that must be overcome during the construction of smart power grid. The topic further studies four aspects of scientific content around power quality emission levels and superposition characteristics of typical electrical equipments: 1) The research on power quality emission characteristic of typical electrical equipments; 2) The research on harmonic superposition characteristics of typical electrical equipments in parallel; 3) The research on power quality emission characteristics of typical electricity load; 4) The research on power quality limit value of standard. The expectation is to reveal the power quality emission characteristics of typical electricity load and the power quality level of utility grid, provide the basis for determining the power quality index limit, furnish optimization design for the access to typical power quality disturbance load, and supply strong theoretical support for the power quality management standard and the reasonable and efficient configuration of related equipments. This topic will promote the study of basic theory on power quality, and the results will directly make theoretical guidance for the further development and application of the strong smart grid.
