This paper solves the OPF calculation problem through the Variable-Metric Method. In the course of calculation, we construct the augmented objective matrix through Lagrange multiplier method, and carry on one-dimensional searching, the gradient calculation and the identity matrix iteration and so on. The computing result shows that the novel method has more advantages than the traditional Newton-Raphson...
In this paper, the asynchronous brake control technology is proposed for the safety of heavy-haul trains in heavy-haul transportations. And the longitudinal dynamics of heavy-haul trains, which is the basic problem of this technology, was studied. A longitudinal dynamical model was established by analyzing the condition of trails, the equipments of rolling stock, train formations, etc. and verified...
