This report presents the results of survey of a 46-kilometer section of the overhead line (OHL) powering the cathodic protection of the Bukhara – Ural Gas Pipeline within the Aktobe Region of the Republic of Kazakhstan. 7 kilometers of this section were previously equipped with bird protection devices (BPDs), which are now totally lost due to destruction of their fastening elements. Inspection of the 46-km section of this OHL has revealed deaths of 2 eagles (Aquilasp.), 1 Common Kestrel (Falco tinnunculus), 1 Black Kite (Milvus migrans), and 3 Greater Flamingo (Phoenicopterus roseus). The conclusion was made that the BPDs of this OHL needed renewal. It was also concluded that instead of OHLs laid along the pipeline route it was advisable to consider other options, including stations of cathodic protection fed from modular-packaged electrical power plants with self-contained micro-turbine units, such as used at the Beineu – Bozoy – Shymkent Gas Pipeline.

The Cost

The article represents results of inspection of power lines for bird casualty in the Minusinsk Hollow, Khakassia, Russia in 2020. Previous inspection was done in the region in 2011 thus our work reveals changes in bird casualty over the last 10 years. The bird mortality on power lines of medium voltage remains remarkably high – mean value for the breeding season is 8.21 ind. per 1 km of line. The most dangerous lines are the ones on concrete poles with pin insulators located in open habitats away from human settlements. Lines of this type attract vast abundance of birds with high species diversity including high percentage of birds of prey and owls. Short lines protruding in the open terrain and parts of lines running through hilly landscapes are of extreme danger. Electrocuted birds are mostly represented by Corvids (66%). Raptors made 28% from the total, represented mostly by the common species such as Kestrel (Falco tinnunculus) – 17.7% and Black Kite (Milvus migrans) – 6.5%, that is character for the forest-steppe zone of Russia. Total damage done to nature by 111.5 km of surveyed power lines was accounted for 18 100 000 Rub (about €204 000 or $243 770). The overall damage which could be caused by the power network of Khakassia was estimated as 64 171 440 Rub per year (that is equal to €723 310 or $864 246). This involves death of more than 3 252 birds per year in one small republic. The damage caused by one electricity pole calculated by the actual results of inspection was 10 485.6 Rub, that is at least 10 time higher that the cost of a set of bird-protection devices for a pole. At the end of the article, we gave our recommendations for minimizing the damage.

Eastern European Countries

Energy supply remains the greatest challenge for many of Eastern European countries and their economy. In post-soviet and ex-Yugoslavian countries, till today there exists a system where some of the power plants rely on high voltage (HV) and medium voltage (MV) power grids in the process of distribution of electric energy (EE) to final consumers. This makes them vulnerable to solar storms due to HV power transformers which are especially sensitive to geomagnetic induced current (GIC). The acquisition of electrical power infrastructure could put the electrical infrastructure out of service from a couple of months to a year or more. Loss of income, for ordinary families, is a primary hazard of a long power outage. Business continuity of industry and other critical infrastructures (CI) is important in this scenario, but it is a significant challenge for small businesses and enterprises as well. This paper introduces ISO 31000 standard to such scenarios with the primary goal of achieving resilience of companies against such disaster as a new method of vial response to avoid scope of similar hazards.

Automation Technology

The trend of increasing demand creates a gap between generation and load in the field of electrical power systems. This is one of the significant problems for the science, where it require to add new generating units or use of novel automation technology for the better utilization of the existing generating units. The automation technology highly recommends the use of speedy and effective algorithms in optimal parameter adjustment for the system components. So newly developed nature inspired Bat Algorithm (BA) applied to discover the control parameters. In this scenario, this paper considers the minimization of real power generation cost with emission as an objective. Further, to improve the power system performance and reduction in the emission, two of the thermal plants were replaced with wind power plants. In addition, to boost the voltage profile, Static VAR Compensator (SVC) has been integrated. The proposed case study, i.e., considering wind plant and SVC with BA, is applied on the IEEE30 bus system. Due to the incorporation of wind plants into the system, the emission output is reduced, and with the application of SVC voltage profile improved.

AbstractThe species–habitat relationships can change during the year because of the seasonality of resources. Therefore, the investigation of habitat use by animals in each season plays a fundamental role in their conservation. The main aim of this research was to investigate the raptor community that spends the winter in Armenia, southern Caucasus, and to explore its relationship with environmental features, such as land use and topography. During January 2012, we collected data by carrying out 15 roadside counts along which we calculated three community parameters: the relative abundance, the species richness, and the species diversity. Then, we carried out a multiple linear regression with the Information-Theoretic Approach, to explain the relationship between the parameters and environmental variables. Besides, we computed a Canonical Correspondence Analysis (CCA) between the species and the environment around their observations. As a general pattern, the community was associated with permanent crops, maybe because of their heterogeneity, which in turn allows them to support higher densities of prey during the winter. The most abundant species was the Black Kite (Milvus migrans), followed by the Common Kestrel (Falco tinnunculus) and the Griffon Vulture (Gyps fulvus). To our knowledge, this is one of the first studies investigating the wintering raptor community in the Caucasus, with raptors generally studied in this area during the breeding season and migration.

Abstract Integration concept of energy resources can complement between the competing energy technologies. This manuscript presents a comprehensive review on the state-of-the-art of concentrated solar power (CSP) integration technology with various energy sources. Compared to CSP alone, integration of CSP and fossil fuel provides promising solution to solar energy intermittence, emissions and installation cost reduction, with 25% increase in electric power generation. On the other hand, integration of CSP with other sources such as geothermal and biomass can supply dispatchable power with almost zero emissions. The electricity produced via integrated CSP and photovoltaic (PV) has better power quality and less cost compared to that produced by PV alone or CSP alone, respectively. Integration of CSP and wind energy can meet peak demand, reduce power fluctuation and provide electrical power at a high capacity factor. However, the lack of reliable biomass, geothermal and wind data with the solar availability at specific locations is the main obstacle for the acceptance and further deployment of hybridization systems. The advantages and limitations of the hybrid technologies presented in this paper according to the literature are reviewed. Moreover, future directions of CSP such as production of hydrogen, solid particles receivers and the integration of supercritical carbon dioxide cycle are also discussed.

The Republic of Korea also suffered direct and indirect damages from the Fukushima nuclear accident in Japan and realized the significance of security due to the cyber-threat to the Republic of Korea Hydro and Nuclear Power Co., Ltd. With such matters in mind, this study sought to suggest a measure for improving security in the nuclear power plant. Based on overseas cyber-attack cases and attacking scenario on the control facility of the nuclear power plant, the study designed and proposed a nuclear power plant control network traffic analysis system that satisfies the security requirements and in-depth defense strategy. To enhance the security of the nuclear power plant, the study collected data such as internet provided to the control facilities, network traffic of intranet, and security equipment events and compared and verified them with machine learning analysis. After measuring the accuracy and time, the study proposed the most suitable analysis algorithm for the power plant in order to realize power plant security that facilitates real-time detection and response in the event of a cyber-attack. In this paper, we learned how to apply data for multiple servers and apply various security information as data in the security application using logs, and match with regard to application of character data such as file names. We improved by applying gender, and we converted to continuous data by resetting based on the risk of non-continuous data, and two optimization algorithms were applied to solve the problem of overfitting. Therefore, we think that there will be a contribution in the connection experiment of the data decision part and the optimization algorithm to learn the security data.
