“…3, we can conclude that by using this approach, the survey of 16 sensors at a remote location of engine room occurred with losses in optical fiber of 0.2•10 -3 dB/m with a reflectivity of 99 %. With a channel power of −10 dB/m, assuming the worst-case scenario with the highest vibration coefficient near the main engine, such losses are not significant and lie within the measurement error [30][31][32][33][34][35].…”

Existing information-measuring systems (IMS) do not fully correspond to the tasks of monitoring electric power installations (EPI) in terms of their characteristics. The capabilities of IMS have certain limitations regarding the probability of measurement results and the degree of invariance to the influence of operational factors. This proves that for modern failure-free EPI technical operation, new diagnostic tools are in demand. Such means should be seamlessly integrated in IMS to enable high operational efficiency and performance reliability. Therefore, it is of particular relevance to tackle the scientific and technical issue of rational combination of protection and preservation of the characteristics of fiber-optic sensors of relative humidity control systems in ship EPI. To solve the problem, the chosen object of this study is the processes of formation and transformation of the diagnostic signal in the means of humidity control. It has been established that the improvement of the characteristics of the control means can be achieved through the synthesis of known optical circuits and the latest materials. To register the parameters of relative humidity, a new circuitry solution was proposed for the sensor based on fiber-optic and elements made of nanomaterials. The main feature of the proposed monitoring tool is invariance to operational destabilizing factors. The scope of application of the obtained research results involves distributed fiber-optic systems for monitoring the technical condition of ship electric power systems. The introduction of a new means for measuring humidity will make it possible to achieve an increase in the efficiency of use and reliability of EPI by reducing the accident rate by 6...11 %, as well as a decrease in operating costs by USD 8...10 per 1 kWh of generated power per year of operation with an average load

The concept of building a traction power supply system with power storage devices provides for their operation to solve the following problems: increasing the transit and carrying capacity, energy efficiency of transportation, reliability of power supply and quality of electric energy. The implementation of pilot projects to solve various problems in the field of traction power supply both in Russia and abroad shows their technical effectiveness.Improving reliability of power supply with the help of storage devices today is considered mainly for options for their use as on-board devices on electric rolling stock or as stationary devices at traction power supply system facilities. Increasing reliability of power supply is achieved through operation of energy storage systems in case of forced or post-emergency modes of operation of traction power supply systems. When solving this problem, it is required to evaluate the voltage level, the change of which is due to the discharge characteristic of the used energy storage device.The objective of the work is to assess the change in the voltage level and energy intensity of the energy storage device used on-board electric rolling stock or as stationary one at traction power supply facilities.Based on the proposed models, the paper assesses the change in the voltage of the energy storage device for the conditions of a short-term absence of voltage in the catenary system using the example of three types of batteries and a supercapacitor. The results obtained in the work allow proceeding to assessment of the performance of electric energy storage systems under various conditions of development of traction load and for different operating modes of the traction power supply system.
