Power grid information safety system based on internet

Abstract

The invention discloses a power grid information safety system based on the internet, and belongs to the technical field of power grid data collecting and processing. Current sensors at all nodes of apower grid can collect data within the same time section. The power grid information safety system comprises a monitoring server which is arranged in a power grid monitoring center, a controller, a data processing module, a humidity sensor, a temperature sensor, an air speed sensor, a current sensor, a season time interval timekeeping module, a peak valley electricity interval timekeeping module,a satellite timing device, a clock control chip and a constant temperature protection mechanism for providing constant temperature protection for the current sensor, wherein the controller, the dataprocessing module, the humidity sensor, the temperature sensor, the air speed sensor, the current sensor, the season time interval timekeeping module, the peak valley electricity interval timekeepingmodule, the satellite timing device, the clock control chip and the constant temperature protection mechanism are arranged at the nodes of the power grid respectively; the controls ends of the monitoring server, the data processing module, the humidity sensor, the temperature sensor, the air speed sensor, current sensor, the season time interval timekeeping module, the peak valley electricity interval timekeeping module, the satellite timing device, the clock control chip and the constant temperature protection mechanism are connected with the controller separately.

Description

technical field [0001] The invention relates to the technical field of grid data collection and processing, in particular to an internet-based grid information security system. Background technique [0002] At present, with the complete automation of the power grid, each node has been monitored in real time, and the two-way flow of current and information on each node has been guaranteed, which will provide massive real-time data streams for the operation and management of the power system. Data mining technology extracts useful knowledge or information from these power grid data streams, which can accurately understand the operating status of the power grid, gain insight into existing abnormalities and potential accidents in a timely manner, perform fault diagnosis, and provide decision support for future decisions. [0003] The data of power grid fault diagnosis is massive. If the massive data is used to directly diagnose the fault of the power grid, the scale and complexi...

Problems solved by technology

However, in the existing Internet-based power grid information security system, the data flow at the fault point is lost after the data flow is reduced, which leads to the failure to locate the fault node in the future.
