The simulation of the 12-pulse rectifier circuit taking into account the real parameters in the programs for modeling digital and analog "ELECTRONICS WORKBENCH" and "NI Multisim".
The characteristic of the method of calculation of an assessment of circuit reliability of power supply of final consumers on the basis of objective factors is given. The substantiation of incorrectness of reliability estimation on the basis of the analysis of indicators of actual reliability is given. The technique of estimation of circuit reliability of power supply to end users, based on the theory of factor analysis, which allows to obtain a qualitative assessment of circuit reliability of power supply with a minimum of initial and reference objective information.
The paper presents the principles of automated diagnostic monitoring systems (ADMS) development and the approach to ADMS monitored parameters selection. The method of ADMS application as a tool for ranking equipment by technical condition proposed by Camlin Power Ltd (UK) is described. A method for ADMS cost-benefit analysis with the rationale for the transition from the foreign criteria "Annual benefit of ADMS application" to the criteria "ADMS Payback period" is proposed. The estimation of ADMS payback period for power transformers and HV circuit breakers is given.
The article Presents the results of the analysis of reliability indicators of generating units (GU) of objects of distributed generation (DG) of different types and power operated under different conditions. The main causes of damage to the GU both in parallel with the power system and in an isolated mode are considered. The influence of frequent short-term, as well as long-term outages of state enterprise objects of DG on the modes of operation of power grid equipment is shown. The necessity of equipping the power grid equipment with monitoring and diagnostics systems, as well as devices of emergency automation is substantiated.
Оn November 17, 2014, almost five years ago, an event took place, the fact of which was sparingly and briefly reflected in newspaper articles and television news – all the work on the restoration of the Sayano-Shushenskaya HPP was completed. Only 2 hydraulic units were able to be restored in the shortest time after the accident, and for a long time the station worked at 1/5 of its rated load. Then new capacities were gradually put into operation. And the last was launched the same hydraulic unit № 2. If symbolic, it is written then some of the media?.
In the present article the task to choose optimal load of a transformer by the minimum of energy losses and summary annual reduced costs over transmitting rated capacity of a transformer.
The Paper deals with the use of various it technologies to create an infrastructure for the collection and processing of data from control and measuring devices for energy consumption.
The article discusses the main problems and bottlenecks of existing software to control technological processes in energy and climate systems. Based on the analysis, we proposed the architecture of a unified automated monitoring and control system for the upper level, implemented on the basis of the Elbrus domestic system-technical platform. An example of the practical implementation of the system is given.
The questions of the organization of an effective strategy of maintenance and repair (MRO) of technological equipment of enterprises of various industries on the basis of information about the current and projected state on the results of diagnosis using predictive analysis approaches on the example of the digital software platform SAFE PLANT
In this article, the author examines the relevance of the use of cold fusion as an energy source, examines the history of testing the e-Cat reactor, the possibility of using cold fusion technology, the principle of operation of the reactor, and the combustion process of the fuel used in the reactor and the amount of energy produced are described by the author chemical formulas.
