This paper introduces the basic ant colony algorithm, the model and its problems in the process of solving the TSPAnt colony algorithm there are many faults about the slow convergence speed and prone to stagnationBecause the ant colony algorithm to search for to a certain extent, all individuals found the same solutions n in exactly, it can not search the solution space in further, it is not conducive to find better solutionsFor the shortcomings of the algorithm, we present a new multiple ant colony algorithms and build the model of the new multiple ant colony algorithm in the paper, the new algorithm through different strategies conducive to the optimal solution obtained by the algorithm of ant colony using different strategies conducive to build mechanism, is to adopt the basic concept of parallel genetic algorithm to search the solution space, this strategy specifically, different groups to avoid solving the problem of local optimum to obtain the global optimumThe simulation results show that the algorithm in solving TSP problems than other algorithms more efficient, have good practical value.

The selective ground-fault protection is greatly valued for the safe and reliable operation of power systems. In order to eliminate the effect of zero-sequence current transformer's phase character on selective ground-fault protection device, this paper proposes a new adaptive principle of selective ground-fault protection, gives out algorithm model of action criterion based on half-wave Fourier algorithm. The simulation results show that this criterion will be with very good selectivity to ground fault.
