Abstract:
Abstract Cable tunnels are the lifeline of cities. Once a serious fire occurs on cables, the toxic smoke generated by cable combustion spreads and escapes, causing serious harm to the surrounding environment and personnel. The heat generated can also ignite nearby combustibles, causing casualties and property damage. Based on the above issues, using fluid dynamics methods, fire dynamic simulation was used to simulate cable tunnel fire scenarios under four variables: wind speed, fire source power, smoke outlet height, and smoke exhaust airflow. The temperature distribution law of the ceiling smoke layer inside the cable tunnel, smoke generation law, tunnel smoke exhaust efficiency, and other factors were clarified, revealing the impact mechanism of the above factors on tunnel fire smoke exhaust efficiency and smoke performance improvement methods. The research results indicate that the combination mode of exhaust air volume and ventilation air speed can effectively control tunnel fire smoke, providing a reference for the fire prevention design of cables in urban cable tunnels.

Abstract:
With the development of the underground utility tunnel in China, the safety evaluation during facility operation inside tunnels is increasingly important after construction. In contrast to fixed fire source in the traffic tunnel, the fire characteristics of the electric cable compartment of the utility tunnel with different ventilation modes are studied. Firstly, the thermal physical parameters of cable material are determined by experiment and numerical simulation. Different fire sealing and ventilation conditions are established according to the practical utility tunnel engineering in FDS. The maximum temperature and smoke gas concentrations are obtained, as well as the heat release rate. The results show that the utility tunnel fire has obvious differences compared with road tunnel fire, where the maximum ceiling temperature and the distributions of smoke is related to fire sealing and ventilation mode. Some suggestions related to evaluation and firefighting are provided for practical purposes.

Abstract:
Рассмотрены особенности развития пожаров в двухпутных тоннелях метрополитенов. Представлены результаты полевого математического моделирования различных сценариев развития пожара. На основе компьютерных расчетов и анализа режимов проектных аварий установлено, что развитие пожара в двухпутных тоннелях сопровождается интенсивным распространением продуктов горения. Основными сценариями аварий, при которых необходимо обеспечивать безопасную эвакуацию людей из перегонного двухпутного тоннеля, являются пожар в аппаратном отсеке головного вагона электропоезда и горение кабельной линии перегонного тоннеля. The analysis of fires at subway facilities has shown that the most complex and catastrophic fires are associated with rolling stock when it is in the tunnel. Fires in tunnels are characterized by the rapid spread of fire hazards, as well as the possible collapse of structures and technological equipment. The peculiarity of fire development in double-track tunnels is the possibility of stopping the movement of electric trains in the opposite direction as a result of fire spread, which leads to the involvement of more passengers in emergency situation. When assessing the fire hazard situation in double-track tunnels, it is also necessary to take into account the possibility of fire spread not only from one carriage to another, but also to a neighbouring train standing on the adjacent track of the tunnel. This study examines fire scenarios and simulates the spread of fire hazards in modern double-track subway tunnels. To calculate the spread of combustion products in double-track subway tunnels, there was used a field fire simulation method based on the SOFIE software package, which has shown its effectiveness in simulating fires in road and railway tunnels. The six main fire scenarios in a double-track subway tunnel were adopted as a result of the analysis of emergency situations: 1 – contact rail fire; 3 – fire in the inter-car space; 4 – fire in the hardware compartment behind the driver’s cabin; 5 – burning luggage in the cabin of the wagon; 6 – burning cable line from cables that do not prevent from burning. Based on computer calculations and analysis of design accident modes, it has been established that the occurrence and development of fire in double-track tunnels is accompanied by an intensive spread of combustion products. The main accident scenarios in which it is necessary to ensure the safe escape of people from a double-track subway tunnel are a fire in the hardware compartment of the control car of an electric train and the burning of the cable line of the tunnel.

Abstract:
Internal-caused cable fires are one of the most common cable fires, and anomalous temperature increase of the cable core is one of the first signs. However, when a cable is operating with electricity, the temperature of the core conductor cannot be monitored directly; therefore, this characteristic cannot be used in detection and prediction of internal-caused fire in electric cable effectively. An analogous transient thermal circuit model is created, simplified, and optimized to properly compute the temperature of the cable core. Afterward, by using the cable internal-caused fire experimental platform and adjusting current carrying capacity of the tested cable, an experiment is conducted for stimulating the very early stage of three-core cable internal-caused fire. The maximum relative errors of the transient thermal circuit model and the trisection transient thermal circuit model are less than 10% when comparing the experimental data with the calculation results, and the average relative error of the calculated value of trisection transient thermal circuit model is 1.08% after layered optimization. The algorithm model can satisfy the requirement for early detection and prediction in the very early stage of cable internal-caused fire.

Abstract:
The article considers the problems of the magnetic field distribution, generated by a power electric cable at the micro-tunnel-boring shield arrangement site by numerical modeling with a further full-scale device model experiment. The impact of foreign magnetic field sources on readings of three-component sensors was established in the process of the study. The considerable existence of parasitic noises, conditioned by external magnetic fields and high sensitivity of the probes, which will require the use of additional filters, was established. When using three-component ferroprobes, the most informative is the probe component coinciding with the tunnel shield longitudinal axis Z. The study showed that with current values greater than 200 A and changes in cable location during the experiment, it is possible to record signals from other sensor components and subsequently determine the location and orientation of the current-carrying cable. The experimental results obtained confirm the feasibility of a multi-sensor probing device for the micro-tunneling machine shield movement control system.

The significant influence of parasitic noise caused by external magnetic fields and high sensitivity of sensors has been determined, which requires the use of additional filters. When using ferroprobe sensors, the most informative is the sensor component coinciding with the longitudinal axis of the tunneling shield. Studies have shown that at current values more than 200 A and change of cable location during the experiment, there is a possibility to register signals on other components of the ferroprobe sensor and subsequent location determination of the cable with current.

Abstract:
碩士<br>國立臺灣大學<br>機械工程學研究所<br>94<br>As far as underground high-voltage electrical cables are concerned, when the cables transmit electric current, a part of electric energy will transform into heat and then dissolve due to electric resistance from the cables themselves. Therefore, designs of cooling systems are the main concern when we try to solve the problem of heat dissipation in underground tunnels where high-voltage electrical cables are installed. In this research we estimate further possible needs based on preceding literatures regarding several such cooling systems. An experimental apparatus is built to study the performance of an indirect cooling system which cooling water tubes are placed through an insulated tunnel. The modeled tunnel that we engage in the simulated tunnel experiment is set up according to similarity laws. At different sections of the tunnel, tests are conducted to measure temperatures of the tunnel, the cooling water tubes, and the electrical cable. The variables are analyzed and studied and references may then be obtained for an optimal design of an underground high-voltage electrical cable tunnel. The result shows that the temperature in the tunnel rises in accordance with the increasing distance from the tunnel entrance. At the entrance of the tunnel, the rising degree of the tunnel’s temperature is the most significant. It indicates that the cooling water tubes in the front section of the tunnel take away heat more. The higher the cooling water tubes’ temperature get, the less heat they take away. As for temperature variation of a single section, the temperature drops compliant with the ascending position away from the heater. At the top part of the tunnel, affected by cold air close to the cooling water tubes, the temperature gets lower and lower around the semicircular wall of the tunnel. The temperature gradually drops to the lowest at the lowest point of the semicircular wall of the tunnel. Water-flow exerts a direct impact on the tunnel’s temperature. The slower the water-flow is, the lower the tunnel’s temperature gets. Though the number of cooling water tubes shows insignificant impact on tunnel’s temperature variation, the more the cooling water tubes are, the smoother the temperature distribution is in the front and rear sections of the tunnel. This indicates the heat transform of the cooling system is more even.

Furthermore, developing the constraints, energy analysis and baseline of cooling system for the designer play an important role in this study. For improving chiller’s COP or replacing chiller, proposing the innovative concepts of geothermal energy combines with cooling system and borehole heat exchanger. This study investigates the temperature distribution through mathematical analysis and program simulation. The simulation results are as follows. With high outside air temperature, high wind velocity and low water temperature, the energy consumption of is the hugest than the others. With low outside air temperature, low wind velocity and high water temperature, the energy consumption of is the lowest than the other. As the wind velocity decreased , outside temperature decreased and water temperature increased, the energy consumption are also decreased. However, the underground tunnel’s temperature is increased when increasing water temperature and decreasing wind velocity. The purpose of this research is to obtain the most effective way of saving energy under the constraints condition.

Abstract The goal of this paper is to study the practical application of Internet of Things technology in the safety supervision of specific areas of the power grid, so as to optimize the safety management process of the power grid and improve its management efficiency and accuracy. For the major components of power facilities including cable tunnels, substations, cable trenches, temperature, humidity, and gas sensors are installed. These sensors use wireless sensor network technology to send data to the next level, and then the data is sent to the big data analysis for further analysis and monitoring. The findings of the study indicate that the sensor network can monitor important environmental information in real time, with the data transmission rate of 250 kilobits per second and the probability of data loss of less than 0. 1%. This monitoring system can give an alarm 5 to 10 min before the fault is likely to happen with an accuracy of more than 95%. By using accurate measurement instruments and a big data processing center, the system has made some remarkable outcomes in the improvement of the power grid stability and security.

Abstract:
In order to compare performance of different fire detection systems commonly used in urban utility tunnel, several types of fire detectors were selected to test by setting up a fire experimental bench to record the response time of detectors. In the experiment, ceramic tube electric heating and alcohol ignition were used to ignite the cable respectively so that fire detectors in the cable tunnel could give an alarm. Results show that contact-type linear temperature sensor has the fastest alarm time for ceramic tube electric heating method. The cable line-type rate-of-rise and fixed temperature detector are more stable, and the alarm times are shorter. The image fire detector did not give an alarm. As for alcohol ignition method, fire is relatively small in the early stage, the temperature in the utility tunnel is relatively low, and the fire detection response time would be long. In addition, wind velocity in the utility tunnel has a great influence on the detector alarm time.

Abstract:
On-site PD measurements on high voltage cables have to concentrate on the cable accessories because there is a remaining risk for assembling faults on site. PD sensors with an appropriate coupling behavior to accessory-internal PD give sensitivities of a few pC or even better. Unfortunately, two main reasons prevent the general use of PD sensors in cable accessories. First of all, the costs for PD sensors have to be balanced with the costs of the accessories, importance of the cable link, consequential costs for outage etc. This is the reason why PD sensors were mainly used EHV cable systems. The second reason is limited accessibility: the PD sensor cable at the accessory has to be connected to a PD detection unit. Accessibility is much more difficult for direct buried cable systems than for cable terminations and tunnel-laid cable systems: the senor cable must pass the ground and the end up in a box on the surface to provide access. This solution causes additional costs and new problems like sealing the sensor cable against humidity, capability to withstand sheath testing etc. By looking for alternative access to PD signals from cable joints of long cable systems, a very simple solution proved suitable: detecting PD at cross-bonding links. To investigate the high frequency propagation of PD pulses in cross-bonding links, computer simulations and laboratory measurements were done.

Abstract:
Abstract The construction and operation of a new light rail transit or metro system in an urban landscape presents a series of corrosion risks to an often densely-packed buried infrastructure. Structures at risk from stray current include the rails, rail infrastructure, buried utility infrastructure such as pipelines, cables and building infrastructure such as steel sheet piles and structural steel work. Design issues that impact on stray current are often wrongly set with the initial design of the system - constrained by factors like electric power and land availability and the desire to limit the initial costs of a project. This has often led to severe stray current damage and serious transit systems management failures. Developing stray current models of transit systems at the design stage can be an invaluable tool to optimise the design. The models allow for the calculation of stray current effects at a rail, rail infrastructure - tunnels bridges - and at third party infrastructure level and helps to drive design decisions. In this paper a series of stray current and corrosion software models were constructed to study the impact of stray current leakage from a proposed transit system on the surrounding infrastructure and used to test the effect of different design solutions and mitigation methods on the infrastructure. Transit operating data were used in conjunction with soil and structure data gathered from site measurements to predict the corrosion impact.

Fatigue and aging of electrical overhead transmission lines is a major concern nowadays in developed countries with ever increasing difficulties to build new lines and an already quite aged network. An important degradation phenomenon of overhead line cables is fretting fatigue close to the suspension clamps due to vortex induced vibrations (VIV). These VIV are generally observed for wind speeds in the range of 1 to 7 m/s. The existing industrial practice for predicting how prone cables are to VIV fatigue is based on a balance between the power generated by the wind and the power dissipated by the cable system. The power generated by the wind has been evaluated through measurements on real line spans and through wind tunnel experiments on rigid and flexible cylinders as a function of frequency and vibration amplitude. The wind tunnel measurement results are mainly performed for constant flow speed. Corresponding results show a scattering from simple to double. Furthermore, complementary investigations are required to better evaluate the power with wind speed variations across and along the overhead line span. EDF R&amp;D (with Code_Saturne open source software) and Politecnico di Milano have evaluated CFD modeling on a mobile rigid cylinder with comparison to detailed wind tunnel measurement results performed by Politecnico di Milano on a 20 cm diameter rigid cylinder equipped with a pressure scanner. This paper presents the steps, the different questions raised, the difficulties and limitations for the setting and the realization of the CFD modeling approach. The comparison between experimental results and simulation results is presented for the mobile rigid cylinder with k-ω SST turbulence model.

Abstract:
Maglev train is a new kind of transportation mode that uses magnetic force to levitate and propel the train along a track. It is becoming more popular especially in China, where several maglev lines are in operation or under construction. Unlike the traditional wheel-based train, maglev train is suspended above the track, with a desired gap of about 8 mm. Due to the small gap, any disturbance of the suspension system may cause failure of suspension. The sources of disturbance include irregularity of track, variation in load, variation in parameters of the train structure (such as stiffness and damping of air spring), unexpected coupling vibration of the train-track-bridge system, and large displacement of the track and bridge. An online monitoring system was designed and installed on a maglev train and the corresponding line to collect the necessary data for analyzing the condition of the train and line and the mechanism of dynamic interaction of the train-track-bridge system. The monitoring items for the maglev train include the acceleration of the maglev bogies and carriages, the suspension gap, and the current of electromagnets. The monitoring items for the line include the acceleration of the bridge and track in concrete straight section, concrete curve section, tunnel wall and steel turnout. They also include relative displacement between concrete bridge and track, and strain of the track. Piezoelectric accelerometers, laser displacement sensors, fiber Bragg grating sensors and electric eddy displacement sensors are used in the monitoring system. All sensors are connected to data acquisition equipment by signal cable. The online monitoring system detected some unexpected conditions of the train and line, such as over-limit irregularity of the track, vibration resonance between the train and track, and suspension failure of the train. The data collected when the train was operating at different speeds and passing through different sections of the line was analyzed. The online monitoring system helped to speed up the debugging process before the maglev line started its official operation.
