Power grid equipment fault positioning detection method

Abstract

The invention discloses a power grid equipment fault positioning detection method, which comprises the following steps of: acquiring related data of power grid equipment through a network and extracting feature data; based on the characteristic data and the actual operation condition of the equipment, determining various fault type data of the equipment, fault judgment parameters, change data of the equipment when a fault occurs, and change data at the acquisition position of each power grid equipment acquisition node, and then sorting and associating the data and storing the data in a data memory; monitoring the operation state of the power grid equipment and the data acquired by each power grid equipment acquisition node in real time, analyzing the monitoring data after the alarm is started, judging whether a fault exists in the monitoring area or not based on the data change, and if the fault exists, judging whether the fault exists or not; if not, splitting the data into a plurality of keywords according to the actual change type of the data, and inputting the keywords into a data memory for searching to obtain the power grid equipment or the acquisition nodes of the power grid equipment corresponding to the keywords. The design realizes the accurate positioning of the fault position of the power grid equipment.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to a fault location and detection method for power grid equipment. Background technique [0002] Electricity is the basic industry of the national economy and people's lives. Its supply and security play a vital role in the national security strategy, economic and social development, and the power system generally includes more grid equipment, and the grid equipment is in the The collective name for generators, transformers, power lines, circuit breakers and other equipment in the power system. During the use of electrical equipment, various failures often occur. If the power failure cannot be diagnosed quickly and repaired in time to restore the normal operation of the power grid as soon as possible, it will lead to power outages affecting daily life, and may cause huge economic losses in severe cases.

[0002] Electricity is the basic industry of the national economy and people's lives. Its supply and security play a vital role in the national security strategy, economic and social development, and the power system generally includes more grid equipment, and the grid equipment is in the The collective name for generators, transformers, power lines, circuit breakers and other equipment in the power system. During the use of electrical equipment, various failures often occur. If the power failure cannot be diagnosed quickly and repaired in time to restore the normal operation of the power grid as soon as possible, it will lead to power outages affecting daily life, and may cause huge economic losses in severe cases

[0003] With the rapid development of my country's electric power industry, the installed capacity of the power grid is increasing rapidly, the scale of the power grid is expanding at the same time, the structure is also complicated, and the operation modes are various. There are more and more alarm information presented to the dispatcher. , the alarm information generated by 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. It is impossible for the controller to correctly analyze these alarm information in a very short time. Therefore, the existing power grid dispatching and alarm system has the disadvantages of difficulty in judging fault information, high labor intensity of manual processing, low efficiency of accident handling, and affecting the safety and reliability of the power grid. , making it difficult for maintenance personnel to know the specific location of the fault in the first time and carry out maintenance work
