Electrical equipment fault monitoring logic judgment method

Abstract

The invention relates to an electrical equipment fault monitoring logic judgment method. The method comprises the following steps: acquiring actuating quantity information of power grid fault moment,namely switch and protection action information; acquiring actuation information from a data collection and monitoring system and a circuit breaker and obtaining the fault time of each actuation nodeof a suspicious fault element; and online judging the equipment in fault in the power grid in real time and forming fault briefing, wherein a transformer substation comprehensively summarize the switch, the protection actuation information and the fault briefing information to form transformer substation fault data information; a scheduling center receives and analyzes the uploaded fault data information, and real-time diagnoses the power grid fault equipment by adopting a logical reasoning algorithm, and compares the diagnosis result with the fault diagnosis result of the transformer substation and checking the same. Through the judgment method disclosed by the invention, the fault information in the power grid equipment can be timely acquired, the accident processing time is shortened, the safe and reliable operation of the power grid is guaranteed, and the security of the power grid equipment is guaranteed, thereby preventing the power grid from abnormal condition.

Description

technical field [0001] The invention relates to the technical field of grid equipment detection, in particular to a logic judgment method for power equipment fault monitoring. Background technique [0002] With the rapid development of my country's electric power industry, the installed capacity of the power grid is increasing rapidly, and the scale of the power grid is also expanding. The structure is also complicated, and the operation mode is various. The alarm information presented to the dispatcher is also increasing. 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. If the information is analyzed and processed correctly, the fault information cannot be fully utilized to find out the area and equ...

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.
