Description

technical field [0001] The invention relates to the field of electric energy quality evaluation of a transmission network, in particular to a method for identifying working conditions of electric energy quality interference sources. Background technique [0002] The contemporary transmission grid is undergoing profound changes in many aspects. With the acceleration of the construction of a strong smart grid with the UHV grid as the backbone grid and the coordinated development of grids at all levels, the factors that generate power quality disturbances in the transmission grid are increasing, and power quality disturbances are also increasing. present new features. The rapid growth of new energy power generation and distributed power generation and the continuous increase in the voltage level of power quality interference source users accessing the system have brought new challenges to the operation of the power grid. [0003] In order to grasp the power quality level of th...
