The thermal resistance model of blast furnace cooling stave is established by combining the entransy dissipation heat resistance with the convective thermal resistance of each heat exchange surface, and the influence of structural parameters of cooling stave on thermal resistance is discussed. The results show that in the heat transfer process of blast furnace cooling stave, the factors that determine its heat transfer performance include the entransy dissipation heat resistance of the stave body and the convective heat resistance of each heat exchange surface. The entransy dissipation heat resistance reflects the thermal conductivity of the cooling stave. The smaller it is, the better the thermal conductivity is. The convective thermal resistance reflects the convective heat transfer capacity of hot surface, cold surface and inner surface of water pipe. The smaller it is, the stronger the surface heat transfer capacity is. It is the theoretical basis for improving the performance of the cooling stave by changing the structural parameters of the cooling stave, reducing the entransy dissipation heat resistance of the cooling stave or the convective heat resistance on the inner surface of the cooling water pipe.

In recent years, the world has witnessed a huge industrial boom in various fields which resulted in an increase in demand for energy. The Sultanate of Oman is one of the oil and gas producing countries, and the country’s energy supply is mainly dependent on oil and gas. This makes the country vulnerable to future air pollution problems and run out of fossil fuels. To mitigate the problems, there is an increasing demand for research and investment in the field of renewable energy. This paper presents the electric energy that would be obtained from the wind energy generated from the cars’ movement turbulence along Muscat Expressway. For the study, the wind speed data was collected using Extech ADL310 Thermo-Anemometer. Four different vertical axis wind turbines (VAWT) were identified to predict the output electric power and its viability. The electric power generated from the wind using the VAWT is presumed to supply power to the expressway streetlights. From the study, it is proved that the street light power demand can be supplied by the 4000 W VAWT with a payback period of 9.2, 3.4, and 0.9 years for a cost of 0.03 OMR/kWh at a wind speed of 5, 7, and 11 m/s respectively. The payback period will be reduced to 4.6, 1.7, and 0.4 years if the government subsidy for the electric power is removed and its cost rises to 0.06 OMR/kWh.
近年来,世界上各个领域都出现了巨大的工业繁荣,这导致了对能源的需求增加。阿曼苏丹国是石油和天然气生产国之一,该国的能源供应主要依赖于石油和天然气。这使得该国容易受到未来空气污染问题的影响,并耗尽化石燃料。为了缓解这些问题,可再生能源领域的研究和投资需求不断增加。本文介绍了马斯喀特高速公路上汽车运动湍流产生的风能将获得的电能。在这项研究中,风速数据是使用Extech ADL310热风速计收集的。确定了四种不同的垂直轴风力发电机(VAWT),并对其输出功率和生存能力进行了预测。利用VAWT产生的风力发电被假定为高速公路路灯供电。研究证明,在风速分别为5、7、11 m/s时,4000 W VAWT可满足路灯电力需求,投资回收期为9.2年、3.4年、0.9年,成本为0.03 OMR/kWh。如果取消政府补贴,电费上升到0.06 OMR/kWh,回收期将缩短为4.6年、1.7年、0.4年。

Owing to the energy crisis in Thailand, alternative energy, especially solar energy, must be utilized. According to the PDP (Thailand Power Development Plan), EGAT (Electricity Generation Authority of Thailand) has to use floating solar photovoltaic (FPV) in several dams. The purpose of this study is to evaluate the potential of using FPV on 12 reservoirs of EGAT hydropower plants in Thailand without affecting the normal operation of hydropower plants. The benefits of the FPV plant are analysed in terms of energy generation using the Perez 1990 algorithm, evaporation reduction using Shuttleworth 1993 algorithm, economic analysis, and greenhouse gas emission reduction. The analysis results are simulated based on the maximum coverage area of FPV that does not influence the normal operation of each reservoir. Based on the amount of energy production of all the considered 12 dams, the Srinagarind Dam can generate the highest power. In the Ubol Ratana dam, the water evaporates at the highest rate. In terms of investment, the production cost mainly depends on the plane of array (POA) of solar irradiance in each dam.

Solar photovoltaic (PV) modules performance is very important as part of the performance of over overall solar PV system. The PV performance is affected by varying factors with some of such factors being external to the PV module design and construction. Dust accumulation on PV module surface is one of such factors because it limits solar irradiance incident in the PV module surface. This paper establishes the yearly maximum output power profile of a PV module and contrast such profile with yearly dust accumulation profile at the same site. A Simulink model and excel are used in the simulation and profiles development. The results show that the maximum power output is lowest around the months of May, June and July which is winter season in the southern hemisphere and improves gradually as summer months are approached. The results also show a close relationship between wind speed and dust accumulation where monthly accumulation increases with increasing wind speed and decreases with low wind speed. The yearly dust accumulation increases cumulatively from one month to the as opposed to the maximum power profile for the year.

Like many countries in the world, Vietnam hopes to optimize the efficiency and conservation of energy, as well as reducing environmental pollution. One of the current challenges is the problem of using electricity for households: 1) The proportion of electricity consumption is relatively high of the total; 2) Power consumption is mainly concentrated during peak hours. It is very difficult to ensure a constant supply of energy, especially during the hot summer, which causes great pressure on national energy security. Therefore, this study focuses on the calculation and analysis of the elasticicities to determine the factors affecting the electricity consumption of households in Vietnam. Hopefully, this study will allow a management agency to deliberate plans to improve the efficiency of domestic electricity use to ensure safety energy security.

When the reactor operates under normal conditions, it will produce a certain vibration with 100Hz as the fundamental frequency, and when this vibration coincides with the natural vibration frequency of the reactor core, it will cause resonance between the two. Therefore, in order to solve this problem, this paper proposes an adjustment method of the natural vibration frequency of the reactor core, which adjusts the length of the air gap by adding an air gap into the reactor core Position and quantity are three parameters to accurately control the natural vibration frequency of reactor core, so as to avoid the resonance frequency range. Through COMSOL finite element simulation, it is found that with the increase of reactor air gap length, the natural vibration frequency of reactor core basically decreases linearly, and the natural vibration frequency of high-order mode decreases faster; At the same time, with the increase of the number of air gaps in the core, the natural vibration frequency of the reactor core basically decreases linearly; Moreover, the air gap at the lower part of the reactor core has a greater impact on its natural vibration frequency, and the air gap at the upper part has a smaller impact. Therefore, when adjusting the natural frequency of the reactor core, the number or length of air gap at the lower part of the core can be increased. This study can provide numerical reference for reactor vibration reduction.

Smart grids have gained attention in recent years in the field of smart cities as a key parameter for the electrical power service, adapted to the new forms of generation and processes associated with the use of electricity. In this sense, the diagnosis of the state of the infrastructure is important to ensure its operation, in which the power transformer is the key element. For this reason, this article presents an Asset Management methodology based on prediction and fuzzy logic to identify the condition of the transformer fleet from the National Laboratory of Smart Grids (LAB+i), considering its conditions. First, the forecasting system is presented together with the base parameters of the fuzzy logic system. Then an implementation analysis is performed with real data. This development allowed identifying the opportunity of using this system in different scenarios, with the challenges and benefits of the prediction methods in the Asset Management framework.

By the end of 2020, the installed capacity of renewable energy in Hunan Power Grid is close to 10.6 million kW, accounting for 19% of the total installed capacity of the province. It is the third largest power source of Hunan Power Grid. Because of being limited by the anti-peaking characteristics of renewable energy, the large peak-valley difference of power load, the lack of adjustability of a large amount of hydropower in flood season, the contradiction of renewable energy accommodation has gradually become prominent. By the end of the 14th Five Year Plan, the renewable energy capacity will further double, and exceed hydropower to become the second largest power source in the province. The accommodation situation is unclear, and relevant research is urgently needed. Against the above background, this article focuses on the current status of the renewable energy power generation operation of the Hunan Power Grid, and sorts out the key technical reasons that affect the accommodation of renewable energy. This paper also conducts sensitivity analysis of key influencing factors to quantify the effect of key influencing factors on renewable energy accommodation. Studies have shown that energy storage instead of conventional thermal power can solve problems such as insufficient peak shaving capacity of the power grid and difficulty in absorbing renewable energy. It is of great significance to achieve the goal of reaching carbon peaks and to ensure the safety of energy and power in the province.

By the end of the 14th Five Year Plan, the renewable energy capacity will further double, and exceed hydropower to become the second largest power source in the province. The accommodation situation is unclear, and relevant research is urgently needed. Against the above background, this article focuses on the current status of the renewable energy power generation operation of the Hunan Power Grid, and sorts out the key technical reasons that affect the accommodation of renewable energy. This paper also conducts sensitivity analysis of key influencing factors to quantify the effect of key influencing factors on renewable energy accommodation. Studies have shown that energy storage instead of conventional thermal power can solve problems such as insufficient peak shaving capacity of the power grid and difficulty in absorbing renewable energy. It is of great significance to achieve the goal of reaching carbon peaks and to ensure the safety of energy and power in the province.","PeriodicalId":329321,"journal":{"name":"2021 International Conference on Smart City and Green Energy (ICSCGE)","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115966666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
