specific Embodiment approach 1

[0019] Specific implementation mode 1: The method of using a drone to perform a three-dimensional patrol of a substation in this embodiment uses a drone to perform live and unpowered patrols on the primary equipment in the substation;

[0020] Live patrol is to patrol related equipment in the primary equipment site of the substation, indoor equipment tanks without exposed busbars, topography and landforms around the substation, and check for floating objects in a live state;

[0021] The unpowered patrol is regarded as the use of drones to conduct close observation of the top of the equipment in the state of power outage maintenance to determine the point of failure and defect.

specific Embodiment approach 2

[0022] Specific embodiment two: this embodiment will further explain the first embodiment, the live tour includes the tour of 500kV substation, the tour of 220kV substation and the tour of 66kV substation.

[0023] In this embodiment, most of the 500kV, 220kV, 66kV and other substations are in a charged state, and most of them are in a charged state when the drone is used to patrol the equipment.

specific Embodiment approach 3

[0024] Specific implementation manner 3: This implementation manner further illustrates the implementation manner 1, and the specific process of the inspection is:

[0025] Step 1. Select the patrol object, determine it as a single device patrol or a comprehensive three-dimensional patrol, and determine the purpose of the flight;

[0026] Step 2. Determine whether the patrol object is electrified. If the patrol object is electrified, it is a live patrol, and if the patrol object is not electrified, it is a power outage patrol;

[0027] Step 3. Make a flight patrol plan based on the results obtained in Step 1 and Step 2;

[0028] Step 4. Test whether the drone is flying normally in a 3D open area of ​​5m×5m×5m, if yes, go to step 5, if otherwise, perform maintenance on the drone, then go to step 4;

[0029] Step 5. Set the drone flying height limit according to the patrol object;

[0030] Step 6. Set the minimum safety distance between the drone and the patrol object;

[0031] Step 7. The ...

Abstract

The invention relates to a method for stereoscopic inspection of a substation by using an unmanned aerial vehicle, and belongs to the field of electric power system-which can solve problem of using manual artificial substation to patrol blind spots and inaccurate visual positioning. the UAV is used for live inspection and unlive inspection of primary equipment in the substation. Live inspection isto inspect the related equipment in the primary equipment site of the substation, the equipment tank without exposed bus bar in the room, the topography and landform around the substation and to check whether there are floating objects under the charged state; Unpowered patrol is to use UAV to make close observation of the top of the equipment under the condition of power failure and maintenance,and to determine the fault point and defect point. The invention is used for patrolling the substation.

Description

Technical field [0001] The invention relates to a method for patrolling substations, and belongs to the field of electric power systems. Background technique [0002] In recent years, with the continuous improvement of the power industry's requirements for safe production, the development of drones, navigation technology, and communication technology has matured, and the application of drones in the power system has become more and more. Many domestic and foreign companies are also trying to use drones as an auxiliary means to carry out the construction and operation and maintenance of power systems. At present, the application of UAVs in the operation and maintenance of power systems mainly relies on carrying relevant optical equipment, patrolling the equipment, monitoring the operating status of the equipment, in order to discover hidden dangers of equipment defects in time. [0003] At present, in the field of substation inspections in our country, only the observation of subst...
