Device and method for monitoring and displaying state of power equipment

Abstract

The invention discloses a device for monitoring and displaying the state of power equipment. The device comprises a monitoring unit, an early warning device, a fault diagnosis module, a comprehensivedisplay unit and a central control unit, wherein the early warning device comprises a trend prediction module and an alarm module, and the trend prediction module is used for generating the operationtrend of the next moment according to the obtained operation state parameters of the power equipment and comparing the operation trend with a monitoring threshold value according to the trend; the alarm module is used for giving an alarm when the trend exceeds a monitoring threshold value or the current operation state parameter exceeds the monitoring threshold value; and the central control unitis used for performing state monitoring, state change prediction, real-time state display and fault grading on the power equipment. By establishing a 3D model for each piece of power equipment and displaying the operation state parameters of each piece of power equipment in real time, the state visualization effect of the power equipment is improved, reliability grading is carried out on all powerequipment, and the management monitoring effect of the power equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a device and method for monitoring and displaying the state of electric equipment. Background technique [0002] In the long-term operation of the power grid system, it is inevitable that the performance will gradually decline, the reliability will decrease, and the failure rate will increase, which will endanger the safe operation of the system. Therefore, the operating status of the power grid system must be monitored. [0003] However, due to the limitations of management, technology and many other factors in the data source of the existing condition monitoring, there is no way to obtain first-hand information in terms of data fusion, and the data interaction with dispatching and relay protection is often done through automation. The quasi-real-time data of the system mapping interface evaluates the equipment with problems according to the management guidelines, and...
