Sistem Monitoring Beban Tiga Fasa pada Gardu Distribusi berbasis Internet of Things

To achieve optimal results in distributing electrical loads, maintaining load balance among phases in a three phase installation system is essential, as any imbalance can lead to electrical power losses. One of the factors contributing to load imbalances is the improper installation of electrical equipment across the phases, deviating from the existing installation design. This research aims to develop a system, known as the Load Monitoring System, capable of storing and providing information about the load conditions installed on a three-phase transformer loading system. This system aims to facilitate the process of adding customers, dividing the load on each phase, avoiding load imbalances, and serving as a reference for routine maintenance of distribution substations annually. The methodology employed in this research is a quantitative method based on testing Internet of Things (IoT) monitoring system tools. The results show that the system effectively monitors load current and voltage at the distribution substation. Additionally, the device enables remote monitoring with the Transmitter capable of sending data to the Receiver from distances ranging from 50 m to 100 m and with the TX Max position in dense environmental conditions and full of obstacles such as buildings and trees or in rural areas with limited internet connectivity.

An Interval-Valued Intuitionistic Fuzzy Bow-Tie Model (IVIF-BT) for the Effectiveness Evaluation of Safety Barriers in Natural Gas Storage Tank

Safety barriers (SBs) are important means of reducing failure risks of process systems. As barriers vary in type and function, their effectiveness needs to be evaluated in order to find a more reasonable configuration strategy. However, in practice, there is often a lack of accurate and complete data relating to SBs, which poses a significant challenge in quantitatively assessing their effectiveness. To address this issue, in this study, we propose a semi-quantitative approach for evaluating the effectiveness of both preventive and protective barriers in process systems by integrating expert elicitation, interval-valued intuitionistic fuzzy numbers (IVIFNs), and a bow-tie model. In this approach, the bow-tie model is first applied to describe the system failure scenarios and the action phases of the barriers, and then IVIFNs with expert judgment are introduced to obtain the failure probabilities of basic events and the effects of SBs. Subsequently, the effectiveness of each barrier is measured by comparing the relative change in failure risk due to the addition of the barrier. To verify the feasibility of this approach, a natural gas storage tank with some barriers was analyzed. The results show that the regular inspection of the deformation or damage of the storage tank has the highest effectiveness, followed by the installation and regular maintenance of safety electrical equipment. Furthermore, compared to a single barrier, multiple barriers can significantly reduce the system risk.

Das ÖBB‐Kraftwerk Tauernmoos – Energiespeicher für die Bahn

AbstractIn 2004, ÖBB‐Infrastruktur AG started the first studies for the construction of a pumped‐storage hydro power plant between the two largest reservoirs of the existing Stubach Valley power plant group in Salzburg's Pinzgau region. Two reversible pump‐turbine units including a full converter with a total capacity of 170 MW and a maximum flow of 80 m3/s are planned. The construction of the 335 million. euro project started in 2020 and will be completed by autumn 2025. In addition to a 50,000 m3 cavern, an 11.5 km tunnel system including the access tunnels and the power water ways have been built. Most of the 11.5 km tunnel system is situated in stable gneiss. A greater challenge is the construction of the two inlet and outlet structures in the high mountain region during the winter season, when the lakes can be held on the lowest reservoir level. Since the remaining construction work is also carried out at an altitude of 1500 to 2250 m above sea level in alpine terrain, the construction company has been facing recurring problems such as snow, cold, wind, mudslides and the associated logistical difficulties. Despite these challenges, the excavation work was completed in summer 2022. The main focus is currently placed on the concrete works in the cavern, which is scheduled to be completed in autumn 2023. This will be followed by the installation of mechanical and electrical equipment as well as the control systems.

Monitoring and Prediction Analysis of Settlement for the Substation on Soft Clay Foundation

The bearing capacity of soft clay foundations is low, which easily causes excessive cumulative and uneven settlement of the substation. This will seriously threaten the safe operation of equipment in the substation. Based on a 220-kV substation project in a coastal soft clay ground, the settlement of the substation building is monitored on the spot, and the settlement law of soft clay ground is analyzed. Furthermore, a three-dimensional finite element model is developed using finite element software named ZSOIL.PC. A numerical model for predicting the settlement of soft clay ground in a substation is proposed using the appropriate element type, material constitutive model, and calculation parameters. The rationality of the numerical method is validated by comparison with the measured data. After improving the soft clay ground with the cement-soil deep mixing method, there are still certain degrees of cumulative and differential settlements in the substation distribution device building, but both are within the specification requirements. The settlement of the soft soil ground in the substation increases with time, but the growth rate gradually decreases and ultimately tends to stabilize after a certain period of time, ensuring the uniformity of foundation treatment is the key to controlling the differential settlement. The research results can provide a reference for the subsequent installation and construction of electrical equipment and the design of substation engineering in soft soil ground.
