Abstract

The invention relates to a grid pollution data acquisition technology, in particular to a grid pollution data bus type acquisition system based on the PQDIF standard. The invention solves the problems of poor real-time data collection, poor data transmission stability, slow data transmission speed and poor data sharing in the existing grid pollution data collection system. Power grid pollution data bus type acquisition system based on PQDIF standard, including power quality monitor, carbon footprint power monitor, monitoring master station, database server, client, switch, gateway, twisted pair, CAN bus; among them, each power quality The monitor, the first switch, and the first CAN bus together form a bus topology; each carbon footprint power monitor, the second switch, and the second CAN bus together form a bus topology; each client, the fourth A switch and the third CAN bus together form a bus topology. The invention is applicable to the collection of grid pollution data.

Description

technical field [0001] The invention relates to a grid pollution data acquisition technology, in particular to a grid pollution data bus type acquisition 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 sa...
