Abstract

The invention relates to a technology for collecting electric network pollution data, and in particular relates to a PQDIF standard-based net collecting system for electric network pollution data, for solving the problems of poor real-time property, poor data transmission stability, low data transmission speed, and poor data sharing property for data collecting in the existing collecting system for the electric network pollution data. The net collecting system comprises power quality monitors, carbon footprint power monitors, a monitoring master station, a database server, client-sides, exchange boards, a gateway and coaxial lines, wherein each power quality monitor is connected with the first exchange board through the coaxial lines to form a net topological structure, each carbon footprint power monitor is connected with the second exchange board through the coaxial lines to form a net topological structure, and each client-side is connected with the fourth exchange board through the coaxial lines to form a net topological structure. The net collecting system is used for collecting the electric network pollution data.

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...
