Online assessment and disposal method for unplanned outage risk of power transmission line due to forest fire

Abstract

The invention provides an online assessment and disposal method for the unplanned outage risk of a power transmission line due to a forest fire, and the method comprises the steps: controlling an inspection monitoring device to carry out the inspection near a power transmission line, and obtaining the current fire information; constructing a fire risk rating standard, and formulating fire disposal methods of different grades in combination with fire over the years and disposal experience; obtaining a fire behavior risk grade according to the current fire behavior information and a fire behavior risk rating standard; generating a fire handling task according to the fire risk level and the fire handling method; and carrying out closed-loop management and control on the monitored fire according to the fire disposal task. Line operation and maintenance personnel and an emergency management department can respond in a linkage mode and dispose in time, the unplanned outage risk of the power transmission line caused by the mountain fire is greatly reduced, and closed-loop management and control are more effectively formed on fire monitoring and disposal.

Description

technical field [0001] The present invention relates, in particular, to an online assessment and disposal method for the risk of unplanned outage of power transmission lines due to wildfires. Background technique [0002] Mountain fires generally occur in inaccessible places, cannot be detected in time and spread quickly. If a mountain fire occurs in the transmission line corridor, if it cannot be detected and disposed of in time, it will cause the risk of unplanned outage of the transmission line. Therefore, for the transmission line Real-time online monitoring of fires for rapid risk assessment and disposal is of great significance for improving the reliability of power supply of transmission lines. When it occurs, there is no accurate explanation on the online rapid assessment of the risk of unplanned outage caused by the transmission line, how to deal with the level change of the fire risk, and how to form a closed-loop management. [0003] For example, patent CN1053211...

[0002] Mountain fires generally occur in inaccessible places, cannot be detected in time and spread quickly. If a mountain fire occurs in the transmission line corridor, if it cannot be detected and disposed of in time, it will cause the risk of unplanned outage of the transmission line. Therefore, for the transmission line Real-time online monitoring of fires for rapid risk assessment and disposal is of great significance for improving the reliability of power supply of transmission lines. There is no accurate explanation on the online rapid assessment of the risk of unplanned outage caused by the transmission line when it occurs, how to deal with the level change of the fire risk, and how to form a closed-loop management

[0003] For example, patent CN105321118A proposes a method for evaluating the hidden danger level of transmission line mountain fires, and patent CN104376510B proposes a method for predicting and evaluating the risk level of transmission line tripping due to mountain fires. Although the above methods can predict the possible impact of mountain fires and assess the impact, but failed to quickly assess the risk level online based on the real-time monitoring of fire development trends, failed to formulate disposal methods according to changes in risk levels, and failed to form an efficient closed-loop management for fire discovery and tracking, risk assessment and disposal. It is difficult to meet the differentiated needs of fire monitoring, early warning and disposal
