The Role of Root Cause Analysis (RCA) in Power Distribution Network Interruption Reduction

Responsibility and reliability are very important for electricity subscribers. Due to their extent, these networks face a variety of challenges, and most of them are recurring but can be prevented if the root causes are identified. One of the methods to identify the root of network problems is to use the RCA method in the analysis of blackouts. RCA is an approach that systematically investigates adverse events and, by gathering evidence and documentation, finds its root causes and offers solutions to address them. Finally, it monitors the implementation of solutions and evaluates their effectiveness. In this chapter, while introducing some of the challenges of medium voltage power supply networks, the root of the problems are extracted, and corrective solutions are presented in three sample problematic feeders. After extracting the solutions, they are divided into two categories: the first category is the solutions specific to the sample feeder, and the second category is the solutions that can be generalized to other parts of the power supply network.

Cabbage Commodity Agribusiness Management

The purpose of this research is to assess and evaluate the performance of the agribusiness system in relation to the Cabbage crop. The Agribusiness System is comprised of four (four) components: In the first place, there is the upstream agricultural industry. The marketing system that has been established is an ordinary marketing system, meaning that it provides complete autonomy to every marketing agency and producer farmer in the conduct of their individual enterprises. Supply networks for cabbage in general tend to be driven by the dynamics of supply and demand in the market, and are still predominated by conventional supply chains whose primary outlets are traditional marketplaces

STRUCTURAL FEATURES OF A WATER INTAKE FACILITY FOR MOUNTAIN AND SUBMOUNTAIN RIVERS

Introduction: The rate of urbanization is currently high. Therefore, it is important to use various elements and devices for water intake and water supply. Purpose of the study: We aimed to consider and analyze the structural features of a water intake facility for mountain and submountain rivers. Methods: In the course of the study, we used the synergistic research principle and statistical analysis. We analyzed the types of water supply networks at mountain rivers and identified the features of water intakes at water sources of this type. Results: A description of water intake features under flood conditions in the Amur Region, exemplified by the Bureya River, was obtained. The mountain rivers have an uneven runoff, which fluctuates not only throughout the year but also throughout the day. The water supply of the mountain and submountain areas shapes the idea of hydrological control over the regime of the mountain rivers. This paper will help to study changes in the average water inflow over the years and thus facilitate an accurate and detailed description of the water inflow characteristics in the Bureya reservoir when planning the water-energy modes of the hydroelectric power plant.

ANALYSIS OF EXISTING SOLUTIONS FOR IMPROVING THE MEASURING AND COMPUTING COMPLEXES OF HEAT SUPPLY NETWORKS

In the presented article, the team of authors considers the existing methods and the main modern technical solutions that are currently implemented in different countries in the diagnosis of heat supply networks. There is a selection of the main directions in the development and design of heat supply networks, which have already been implemented or supported by scientific teams from different countries. Various methods and technical features of diagnostics are reviewed, strengths and weaknesses of the presented solutions are highlighted. The reviewed works were subjected to detailed analysis, which revealed the presence of a high interest of the scientific and industrial community in the integration and improvement of existing digital technologies in the development of heat supply systems, which would be closely related to forecasting and modeling processes in this industry. The team of authors highlights the main vectors for the development of this sector, citing an example of a significant increase in the degree of digitalization of final products, which makes it possible to use data analytics to obtain effective technical solutions regarding heat supply networks. Separately, the positive experience of different countries in this industry is noted when using neural networks not only in the design of heat supply networks, but also as a target industry as a whole. Assumptions are put forward about the need for a detailed analysis of the existing foreign and domestic experience, as well as scientific developments in this area, in order to determine the most suitable technical solutions on the territory of the Russian Federation, which will take into account the climatic characteristics of the country and be based on methods of large data analysis, computer vision and simulation. modeling.

Enhancing the Method of Decentralized Multi-Purpose Reuse of Wastewater in Urban Area

The reuse of treated wastewater is attractive as a communal source of excess water source in water-scarce counties and nations. The expansion of the urban population and the increase in the coverage of water supply networks and sewage networks will raise the amount of municipal sewage. This can turn into a new-fangled water resource. In the current research, the new campus city was selected as the first case study to design a wastewater reuse and recycling system. Accordingly, one of the most important innovations in the proposed research is the unique applied dimensions, in addition to its first-time performance, and the application of the Geo-land method in wastewater recycling as the theoretical dimension of the design. Clustering the decentralized reuse of wastewater for urban areas showed that significant parts of residential areas are located in the first high priority group. Urban planners can consider the results in establishing a comprehensive plan to prioritize the decentralized use of wastewater in the urban area.

The 2011 Bangkok Floods: Live Peacefully (Yoo Hai Yen), Live Harmoniously (Yoo Hai Pen Suk)

<p>Thailand’s Bangkok has experienced rapid population growth and subsequent expansion over recent decades. It has resulted in an unintentional increase in vulnerability within rural-residential and metropolis areas. Flood prevention strategies, such as dams, irrigation canals, and flood detention basin, and Kaem Ling ‘Green belt Embankment’, have been slowly built and activated in response to this suburban catastrophe (Vanno). In recent years, King Rama IX of Thailand, initiated Kaem Ling’s, ‘Monkey’s Cheek’s’ project; a reference to the common parable of an intelligent monkey storing its food in its saggy cheeks rather than swallowing. This has allowed the Western and Eastern suburbs of Bangkok to function as waterways, diverting the destructive water paths away to protect the metropolis. Beginning in July 2011, a significant rainfall from the highlands of Thailand flooded down to Bangkok. With affected areas lying less than 10 metres above mean sea level and some as low as 1.5 metres, some areas remained flooded until January 2012. By October, the inundated metropolitan Bangkok began to negatively impact on industries, such as computers and automotive. Both critical supply networks for other manufacturing operations outside of Thailand. This ‘vulnerability’ where the inter-connectedness of economies could mean the closing of factories and manufacturing assembly lines in one country because of a flooding disaster in another had not been recognised. The 2011 Thailand’s flooding death tolls surpassed 815 deaths (with 3 missing), affected 13.6 million people and classed 65 of Thailand’s 77 provinces as flood disaster zones (Benfield, 2012). During the extreme environmental activity, decisions were made to close several district gates in last-ditch efforts for protecting the metropolitan areas. This caused many other peri-urban areas of Bangkok to flood. These suburban areas were intended to act as waterways to protect the metropolis, but instead became a reservoir. Nimitmai 40 Road, situated in Khlong Sam Wa district, was in the middle of the 2011 flooding zones became the locus and main area of interest in this research. Several initial studies, of precedence and technical data, explored objectives of building resilience in response to flooding and community. This research further utilised field study surveys, interviews, and case studies, all of which provided a wealth of information and contextual material. They contributed to design propositions developed through a series of critical reflections. This research aimed to build community resilience, encapsulating spiritual elements in cultural and psychosocial elements of suburban Thai community’s livelihood and to provide flood resilience through both non-technical and technical solutions. Final outcomes of the design iterations suggested a merging of Thai monastery and community centre as a spiritual anchor for the community’s resilience and strengthen my neighbourhood’s sense of place.</p>
