Technical systems which operate in the power industry are the critical systems of strategic importance. In case of such systems the task consisting in the avoidance of the failure occurrence has an extraordinary significance. The failure occurrence is interpreted as the transition of the system technical state from the area of the ability states to the area of the inability states. Therefore, the...
An optimized system management of a power system must take care of the actual operational and energetic duty of the power system distribution, promoting a high efficiency of power cables and avoiding their excessive gap on load and gap on lifetime. A procedure based on the Arrhenius model of the Thermal Aging of Insulating Materials allows implementing a tool to calculate the life loss and the residual...
The paper present the methods used in recent years in the national power grid to operate more efficiently as high voltage equipment. It includes shares of minor maintenance and operation undertaken by our company for management installations. It also briefly describes the results of applying new technologies and the technical analysis performed using such technical data. As part of asset management...
Many work related electric accidents occurred at workplace and they were fatal or non-fatal. The situation of electric accidents at workplace worldwide is investigated by reviewing the standard work practices, to offer perspectives on the types and kinds of statistics available, the factors regarded as influencing their occurrence, their consequences, and also methodological shortcomings. Worldwide,...
At present, the reliability and maintainability level of domestic helicopters has been greatly improved, however, since the logistics delay time is too long, the operational availability of helicopters has not been significantly improved. The paper analyzes the causes of this situation and puts forward the concept of the integrated system of operation maintenance support in order to realize the gapless...
The evolution of the harmonized set of ISO/IEC/IEEE 15288-12207 related standards and technical reports that are discussed in this International Standardprovides detailed requirements and guidance on the application of system life cycle processes. This International Standard unifies technical and managementrequirements and guidance from several of these sources to specify the requirements for the...
The paper proves that a set of tasks of unmanned aerial vehicles grouping operation belongs to organizational management problems. To ensure prediction for the given instants of time, simulation of numerical state of facilities basic resource is recommended.
This work presents a geospatial computational tool—GeoLCOE—for estimating the levelized cost of energy (LCOE) of multiple power generation technologies in Colombia. This tool is designed for assessing both economically and technically new generation projects across the Colombian geography. This tool computes the LCOE of renewable and non-renewable generation technologies for multiple locations based...
The operation and the maintenance of electric power systems are governed by a set of procedures required to ensure that any intervention on the system will be performed under safe conditions, considering the inherent dangers coming from the presence of live conductors, parts and components. Although the main safety-related concepts like energy isolation, earthing, interlocking and lockout-tagout are...
Power system communication network operation & maintenance is most important for power system stability. With the development of power system communication network and the merging of information and communication, the requirement of power system communication management is higher and higher. And the rules of power system communication network is much more complex than before. So it is very urgent...
A photovoltaic PV installation is exposed to extreme ambient conditions due to the solar radiation, humidity, wind and thermal stresses. A comprehensive design of its power system could follow two complementary strategies: one consisting in the adoption of special components and the other one consisting in an adequate installation of standard components providing a continuous control of its operation...
The article focusing on the situation of transmission network operation and maintenance introduces a monitoring and controlling management system for transmission network operation and maintenance. This paper says its principle, structure, software function and application. The whole system containing circuit monitoring device, maintenance monitoring device and the background management system uses...
Recommended practices for the numerous personnel who are responsible for safely operating and managing industrial and commercial electric power facilities are provided. In this recommended practice, plant engineers are provided with a reference source for the fundamentals of safe and reliable operation and management of industrial and commercial electric power distribution systems.
Industrial electrical systems require proper installation, operation and maintenance of equipment for a facility to operate safely and efficiently. Of the many types of electrical installations, those in hazardous areas are likely the most difficult to deal with. Misunderstanding or misinterpretations can easily lead to unsafe conditions that put personnel and facilities at risk. This presentation...
The O&M (Operation & Maintenance) phase of IT project is the phase when IT project yields economic return or performs its function and the owner gains the interest. Whether the investment and construction of IT project is successful or not depends on the result of the maintenance. Moreover, the selection of IT project O&M model has an important effect on the efficiency of IT project O&M...
Revision of ISO/IEC 15288-2004. This International Standard was jointly developed by ISO/IEC and IEEE. This International Standard establishes a common process framework for describing the life cycle of man-made systems. It defines a set of processes and associated terminology for the full life cycle, including conception, development, production, utilization, support and retirement. This standard...
Supersedes Std. 12207.0 and also makes 12207.2 obsolete. This International Standard was jointly developed by ISO/IEC and IEEE. This International Standard establishes a common framework for software life cycle processes, with well-defined terminology, that can be referenced by the software industry. It applies to the acquisition of systems and software products and services, to the supply, development,...

The BcN architecture of VPWS is introduced as a service model. The network elements forming the BcN data plane and a centralized controller forming the BcN control plane functionality are briefly described. A mapping architecture which transports the VPWS signal is presented. We examine the propagation of the maintenance signal under the network failure condition. The main purpose of this architecture...
