The conditions of compensation of magnetic and mechanical losses during the test of hauling electric machines according to the Potier’s chart are considered.

The analysis of power indices of process of compensation of magnetic and mechanical losses in the charts of mutual loading of hauling electric motors with the use of electric power source is resulted.

Official Bond is a common form of engagements in an education institution funded by an agency. The engagements result that the granted parties must work for a certain period. The violation against this official bond will cause disadvantages for the agency... see more

The analysis of power indices of process of compensation of magnetic and mechanical losses in the charts of mutual loading of hauling electric motors with the use of electric power source is resulted.

The analysis of dependence of the magnetic losses in hauling electric motors on the frequency of armature remagnetization is presented. A universal characteristics of the magnetic losses reduced to the frequency of remagnetization of 50 Hertz is offered.

The conditions of compensation of electric losses at the test of hauling electric engines by the Hopkinson’s scheme are considered.

In this work the generalized mathematical model of an electrical network of the electrified railway junction is proposed. An estimation of influence of static var compensators installation on electric power losses in a network is executed on the basis of ... see more

Installing a synchronous condenser (SC) onto an electricity grid can assist in the areas of reactive power needs, short-circuit strength, and, consequently, system inertia and guarantees better dynamic voltage recovery. This paper summarizes the practical... see more

Current offshore wind farms (OWFs) design processes are based on a sequential approach which does not guarantee system optimality because it oversimplifies the problem by discarding important interdependencies between design aspects. This article presents... see more
