Reliability of power supply of consumers is an important task in the process of transmission and distribution of electric energy. The paper proposes a method for assessing the consequences of power failures of monoconsumers of electric energy on the example of an oil company and an adjacent power grid company. The uniqueness of the developed technique lies in the possibility of reliable calculation of reliability of power supply of complex branched electric networks without taking into account the specific scheme of power supply. The accuracy of calculations is increased due to the use of data directly studied power system, taking into account the specifics and operating conditions of specific equipment, instead of the average information. Classification of failures on the main reasons in electric networks of the oilproducing enterprise of the far North that allowed to develop actions for increase of level of reliability of power supply is made.

Existing examples of prototypes of ground-based robotic platforms used as a landing site for unmanned aerial vehicles are considered. In some cases, they are equipped with a maintenance mechanism for the power supply module. The main requirements for robotic multi-copter battery maintenance systems depending on operating conditions, required processing speed, operator experience and other parameters are analyzed. The key issues remain questions of the autonomous landing of the unmanned aerial vehicles on the platform and approach to servicing battery. The existing prototypes of service robotic platforms are differed in the complexity of internal mechanisms, speed of service, algorithms of joint work of the platform and unmanned aerial vehicles during the landing and maintenance of the battery. The classification of robotic systems for servicing the power supply of multi-copter batteries criteria is presented using the following: the type of basing, the method of navigation during landing, the shape of the landing pad, the method of restoring the power supply module. The proposed algorithmic model of the operation of battery power maintenance system of the multi-copter on ground-based robotic platform during solving the target agrarian problem is described. Wireless methods of battery recovery are most promising, so further development and prototyping of a wireless charging station for multi-copter batteries will be developed.

Switch Mode

The procedure of energy transformation inthe converters of switch-mode power supply(SMPS) as electromagnetic interference (EMI)sources are considered. Analytic survey of theprocesses of EMI generation from SMPS is given. Spectral levels of real and standard pulsessequences are compared. It’s shown that EMIlevels sometimes exceed standards, thereforeit’s necessary to elaborate the classification ofSMPS converter as EMI sources

Tilt Sensors

A review of various kinds of solid tilts sensors, using a free mechanical member for generation of electric-contact (mostly a ball), is presented. Standard and original solutions are discussed. The latest patents are described. A classification of the existing solutions with respect to their sensing principle is proposed. Possible types of the electric/electronic circuits are discussed. Advantages of these sensors are emphasized: mainly optional operation without power supply, resistance to electrostatic discharges, and simplicity of signal processing. Technological details are briefly introduced, along with miniaturization prospects. Additionally, liquid tilt sensors are succinctly characterized. The most typical tilt sensing techniques are concisely compared.

Analysis Of Failures

Discussed issues that affect the reliability of various elements of the infrastructure of railway transport, such as the railway track, power supply devices, artificial structures, rolling stock, automation devices, telemechanics and communications. The main technical devices of railway transport are listed. The classification of failures in the operation of technical means of transport is given, depending on their category; classification of technical equipment, the failures of which are subject to obligatory accounting or to be accounted for in cases of their influence on the transportation process in accordance with regulatory documents in force in railways. As a result of working with the initial data on failures that caused train delays, the main services involved in the occurrence of failures in the operation of technical equipment at the Northern Railway training ground were identified; also provides an analysis of failures in the operation of technical equipment in the regions of the Northern Railway. Classifier of the causes of failures in the operation of technical facilities by services and the causes of the occurrence on the Northern Railway, which most failures fall on, is formed; identified the main reasons for the failure of the relevant units of the railway transport. The dependence of the available bandwidth on the reliability coefficient is given.

Abstract This paper highlights the methods of resenting mode in the transudation with distributed parameters. The transient parameters of the power supply were analyzed. It was discovered that resonance is provided in a small range of movement of the moving component of the sensor in known turbofan engines, indicating that the known techniques of sustaining the resonance mode are flawed. Further study should focus on developing novel methods for preserving resonance mode over the entire range of change of the converted value, general principles of turbojet engine construction, and a complete examination of their resonant circuits, according to the findings.

Modelling And Optimization

The expansion of renewable energies is progressing strongly. The influence on the power supply networks by the volatility of the infeed must be met with new concepts. In this paper we investigate the possibilities of integrating microgrids as a cooperating unit in the power supply network to support further expansion of RES power plants. In this paper a differentiation of microgrids from similar network structures is established, a classification of proposed groups is made. Then, after the description of simulation of components in a microgrid, with practical advice, an example model is shown, which aids the dimensioning of the components within a microgrid to achieve a specified goal.
