Description

technical field [0001] The invention relates to a power grid pollution data collection technology, in particular to a grid pollution data collection system based on the PQDIF standard. Background technique [0002] During the operation of the power grid, various loads (such as nonlinear loads, impact loads, fluctuating loads, and asymmetrical loads) will cause harmonics, voltage fluctuations and flicker, surge impacts, and three-phase imbalances in the power grid. These phenomena are collectively referred to as grid pollution. On the one hand, grid pollution will cause serious harm to the safe operation of the grid (such as grid tripping, abnormal fluctuation range of grid frequency, grid voltage drop, instantaneous power supply interruption of the grid, etc.), and on the other hand, it will cause serious damage to the safe operation of the load (such as Cause interference to the load, cause load failure, cause load burnout, etc.). Therefore, in order to ensure the safe op...
