Electric power equipment fault early-warning method

Abstract

The invention relates to an electric power equipment fault early-warning method which comprises the following steps of acquiring acting quantity information of a power grid in a fault occurrence time, namely switch information and protection action information; acquiring action information from a data acquiring and monitoring system and a circuit breaker, and obtaining fault occurrence time of each action node of a suspected faulted component; discriminating faulted equipment in the power grid in a real-time online manner and generating fault brief information; combining the switch information, the protection action information and the fault brief information by a transformer substation for forming transformer substation fault data information; receiving and analyzing uploaded fault data information by a scheduling center, performing real-time diagnosis on the fault equipment of the power grid according to a logical reasoning algorithm, and performing comparison checking on the diagnosis result and the fault diagnosis result of the transformer substation. The electric power equipment fault early-warning method has advantages of acquiring fault information in the power grid equipment in time, shortening accident processing time, ensuring safe and reliable operation of the power grid, ensuring high safety of power grid equipment and preventing abnormity of the power grid.

Description

Technical field [0001] The invention relates to the technical field of power grid equipment detection, in particular to a method for early warning of power equipment failures. Background technique [0002] With the rapid development of my country's power industry, the installed capacity of the power grid is growing rapidly, and the scale of the power grid is expanding simultaneously, the structure is also complicated, and the operation mode is various, and more and more alarm information is presented to the dispatcher. When the power grid is operating normally, the alarm information generated by the power equipment still needs to be processed manually; when the power grid fails, hundreds of alarm information will be sent to the control center in a short time, and it is impossible for the controller to give an alarm in a very short time. Information is correctly analyzed and processed, and the fault information cannot be fully utilized to find out the area and equipment where the ...

Problems solved by technology

When the power grid is in normal operation, the alarm information generated by the power equipment needs to be processed manually; when the power grid fails, hundreds of alarm information will be sent to the control center in a short time, and it is impossible for the controller to respond to these alarms in a very short time. Correctly analyze and process the information, and cannot make full use of the fault information to find out the area and equipment where the fault occurred

Therefore, the existing power grid dispatching and alarm system has the disadvantages of difficulty in judging fault information, high labor intensity of manual processing, and low efficiency of accident handling, which affects the safety and reliable operation of the power grid.
