The invention relates to the electric network pollution data collection technology, in particular to an electric network pollution data star-shaped collection system based on a PQDIF standard. The electric network pollution data star-shaped collection system based on the PQDIF standard solves the problems that an existing electric network pollution data collection system is poor in data collection real-time performance, poor in data transmission stability, low in data transmission speed and poor in data sharing performance. The electric network pollution data star-shaped collection system based on the PQDIF standard comprises power quality monitors, carbon footprint power monitors, a monitoring master station, a database server, client sides, exchanges, gateways and power lines, wherein all the power quality monitors and the first exchange jointly form a star-shaped topological structure, all the carbon footprint power monitors and the second exchange jointly form a star-shaped topological structure, and all the client sides and the fourth exchange jointly form a star-shaped topological structure. The electric network pollution data star-shaped collection system based on the PQDIF standard is suitable for collection of electric network pollution data.
Description
technical field [0001] The invention relates to a grid pollution data collection technology, in particular to a grid pollution data star 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 ope...
