In the complex electromagnetic environment of the transmission line, a large number of electromagnetic sensitive components in the control system of the live working robot cannot work stably and reliably. Therefore, aiming at this problem, this paper takes the 110kV transmission line live working robot as the research object, and conducts electromagnetic analysis and protection design for it. According to the three elements of electromagnetic interference, a solution to the electromagnetic protection of live-line working robots is proposed. In order to realize the live working of the robot, the equipotential mode is selected as the working mode of the robot, and the feasibility of the equipotential mode is verified through experiments.
In order to solve the problem of slow convergence and local optimum of traditional crisscross algorithm, a hybrid topology crisscross algorithm (HTCSO) is proposed and applied to solve the dynamic economic dispatch problem of power grid. The hybrid topology combining ring regular topology and stochastic topology is adopted to increase the diversity of the population and expand the solution search space, so as to improve the convergence accuracy and convergence rate of CSO algorithm. Experiments on small-scale 10 units system and large-scale 100 units system show that the proposed hybrid topology crisscross algorithm has faster convergence speed and better convergence accuracy compared with other swarm intelligence optimization algorithms, which provides a reference case for real-time accurate dispatching and carbon emission reduction of power grid.
