Power grid safety alarm device and system

Abstract

The invention relates to a power grid safety alarm device and system. The device comprises a monitoring module which is used for monitoring the state of a power grid according to a detected control command, and carrying out the analysis and calculation of the collected information generated during the carrying of the power grid, and obtaining the feature information of the power grid; the remote processing module is used for performing remote power grid fault judgment and fault positioning in a preset positioning label range, and storing a power grid fault positioning result according to the power grid operation condition; and the alarm module is used for giving an alarm for an abnormal condition and the fault according to the changed power grid characteristic information and a pre-constructed event rule base. By adopting the device, the safety of the power grid can be detected in real time, and an alarm can be given in time when a fault occurs.

Description

Power grid safety alarm device and system technical field [0001] The present disclosure relates to the technical field of power grid security monitoring, and in particular, to a power grid security alarm device and system. Background technique [0002] Electricity has become an essential part of our daily life, so the security of the power grid is important in the production and transportation of electricity. It is extremely important, so it is necessary to monitor various data of the power grid. [0003] The current power grid monitoring business relies on the monitoring method that the alarm information responds one by one, and each piece of information needs to be monitored one by one. Identify, analyze and give feedback. With the continuous expansion of the scale of the power grid, the intelligent level of the power grid continues to improve, and the access control The number of substations, power grid equipment and alarm information that the organization achieves c...

Problems solved by technology

With the construction of UHV smart grid, the development of UHV power grid, AC / DC hybrid and new energy, the complexity of the interconnected grid is getting higher and higher, and the amount of power grid operation status and information grows in geometric progression, although it is expressed one by one by conventional classification indicators The state of the power grid can reflect the security situation of the power grid in detail, but it cannot intuitively perceive the overall situation of the power grid security

When the power grid system suddenly encounters an accident or is about to be in danger, the dispatcher is often unable to timely and accurately perceive the impending problem in the face of massive data and various classification indicators, and cannot detect the safety of the power grid in real time. The ability to issue alarms in time has brought great hidden dangers to the safety of the power grid.
