The conventional substation differential power supply zoning method uses the grey clustering coefficient to determine the power supply weight of each zone, which is vulnerable to the influence of the dynamic entropy value of power supply, leading to the high power supply load. Therefore, a new substation differential power supply zoning method needs to be designed based on grid division. That is, the grid division is used to predict the power supply load of substation partition, and then the differential power supply partition model of substation is constructed by combining the load characteristics complementation, thus realizing the differential power supply partition of substation. The case analysis results show that the designed substation differential power supply zoning method based on grid division has a small power supply load, which proves that the designed power supply zoning method has a good power supply effect, can reduce power supply loss, has a certain application value, and has made a certain contribution to reducing the regional power supply cost.
In the current installation or maintenance process of large substation equipment, due to the lack of special hoisting equipment to cope with complex substation operation conditions, resulting in sustained power maintenance time, construction personnel safety can not be guaranteed, and other problems. For these issues, this paper proposes a new type of substation special hoisting equipment program and designed a related mechanical structure. The equipment uses the bottom crawler walking mechanism to enter the narrow working space and uses the frog legs to achieve balance and prevent overturning. The three-degree-of-freedom double mechanical arm and the high-altitude manned device carry out the hoisting of the substation equipment and the human intervention of the equipment, to complete the accurate and efficient hoisting operation of substation equipment.
Lightweight structure of a rescue robot for a high voltage transmission line is the key to its practical stage. In this paper, taking the shell of the rescue robot arm of high voltage transmission line as the object, aiming at the minimum mass of the structure and taking stiffness as constraint conditions, the topological optimization design of the structure was carried out, and the three-dimensional topological configuration of the shell structure was obtained. According to the topological optimized configuration, the three-dimensional structure of the manipulator shell is reconstructed and the finite element stress is verified and analyzed. By comparing the stress analysis results before and after reconstruction, it is found that the mass of the reconstructed manipulator shell is reduced by 41.40% under the conditions of satisfying the structural strength and stiffness. The research ideas and results in this paper can provide ideas for the pro-quantitative design of other structures of the transmission line rescue robot.
