In article the issues of electric power imbalance in train traction research are considered, including the method providing an estimation of the contribution of imbalance components to its total value with the possibility of their separation between the participants of the transportation process: the electrification and power supply service, the automatics and telemechanics service, the directorates of locomotive traction and motorized rolling stock. Described method allows in more detail to analyze the factors that affected the change in the components of imbalance and further develop organizational and technical measures to reduce it.

The presence of ever-changing electrical traction load, distributed not only in time but also in space leads to the complexity of the detailed monitoring of the energy efficiency of the organization trains JSC «Russian Railways». Therefore one of the priorities of the energy strategy of JSC «Russian Railways» is the introduction of innovative technical tools and technologies. The paper discusses the main provisions and some functionality created automated information-measuring complex accounting of electric energy in the electric rolling stock. Reviewed the processing of data for evaluation of energy efficiency of trains on the basis of the developed system.

We consider the ways of increasing the effectiveness of the information-measuring complex of an automated system for monitoring and metering electricity. The possibility of reducing the volume of telemetry traffic in information transmission channels and increasing the energy efficiency of information-measuring equipment is investigated.

We consider the concept and architectural aspects of the development of the corporate information sys-tem for monitoring and resources accounting. The relevance of improving automated systems is due to the intensification of the use of modern information technologies in industry. The aim of the work is to select the architecture of the distributed information system for monitoring and resources accounting (hereinafter - the system), which ensures prompt decision-making in the management of technological objects. We consider the current trends in the development of information systems and concepts that provide the requirements established for systems of this class and purpose. The system is based on previously designed prototype that has been put into operation, and differs from it in new solutions that allow to increase mobility and fault tolerance. We describe the basic implemented architectures and the system functionality.
