While low cost ACS 712 5A current sensor and Arduino voltage sensor modules were used to measure PV output current and voltage. The 1.25 kWp grid connected PV system were used to test the real-time measurement system. The data received exactly same as sensed data that sent from remote area with time delay around 3 to 4 seconds. The solar panels in average have produced power twelve hours per day for clear sky, however for raining, overcast and cloud covered sky, PV power decreased and grid disconnected earlier before sunset and the PV power curve show an irregular profile. Experimental results demonstrate that real-time PV data can be recorded using Zigbee sensors network. This information can be used as a further reference for performance and energy saving analysis of PV system installed in West Sumatera.","PeriodicalId":149415,"journal":{"name":"2016 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115676103","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}

Large-scale productions are carried out to produce various food types such as chutney, pickles, jelly, juice, smoothie and ice-cream in industrial scale. As a result mango pit which is one form of biomass generated basically as an industrial waste. Therefore mango pit can be utilized to generate energy by applying an appropriate technology of energy generation. In addition Coconut shell and Gliricidea are already established biomass energy sources in Sri Lanka. This study intends to develop an updraft gasifier for mango pits and compare performance with Coconut shell and Gliricidea. Considering abundant availability of mango pit, it has been introduced as a new biomass energy source to Sri Lanka. A laboratory scale updraft gasifier was designed and fabricated to conduct experiments.

Wireless electricity ensure that the cell phones, laptops, iPods, and other power electrical devices get changed on their own, with no need of plugging them that can prevent the sockets with all sorts of wires. Wireless power transfer is when the magnetic field is transferred over short distance. The magnetic field is created using inductive coupling between coils of wire or electric fields using capacitive coupling between electrodes. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. The carrying fluxes that induce in the inductor can be captured by another inductive coil that can produce an induced flux between the receiver coils that coupled to the primary coil. Since this technique using magnetic field to transfer the electrical energy, the flux that produces in the primary coil must be in high density with high frequency. Thus, the tesla coil is used as a transmitter to produces high voltage, high frequency and low alternating current in order to produce high density flux. In this work, a tesla coil is a main part of transmitter component in wireless electricity apparatus and need to develop with a view to demonstrate how magnetic induction is coupled to perform a wireless power transfer. In addition, the construction of winding coils of the tesla coil would be the great effects in order to provide electricity to supply a load without wires in distances. The advantages of the wireless electricity system would be completely eliminating existing wires for electrical appliances between power sources. With wireless electricity, the electrical system will be more secure as it will prevent user from electrocution of current and the power failure due to short circuit and fault or power loss on cable would never exist.","PeriodicalId":149415,"journal":{"name":"2016 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122251825","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}

The first method is considered with no-swirl flow at runner exit, while the second method with swirl flow at runner exit. The design results show that both methods produce the different stagger angle at each blade section of the runner blade. The numerical simulation was performed using computational fluid dynamics (CFD) approach to calculate the performance characteristic of the runner blade designs. Commercial software ANSYS CFX was used as CFD solver. From the operating simulation results in conditions, no-swirl flow assumption at runner exit achieved the greater power than the swirl flow assumption at runner exit. The maximum runner efficiency of swirl flow assumption at runner exit is higher than no-swirl flow assumption. However, it would be more beneficial for using the design condition that achieve the greater power in operating conditions. Thus, no-swirl flow at runner exit design assumption is recommended during the design phase of the runner blade of axial flow hydraulic turbine type propeller.","PeriodicalId":149415,"journal":{"name":"2016 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129723830","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}

Thermal efficiencies of the engine power plants range from 25–44%, while more 60% of the feeding energy is converted to waste heats, which mainly are engine cooling and exhaust. Recovering and utilizing such waste heat improves the energy efficiency. The objective of this study was to investigate the potential and feasibility of a cogeneration driven by the waste heat of the engine power plant in Thai POMs. A case study approach was conducted, and secondary data of the mill were collected and used as baselines for the calculation. The cogeneration model and techno-economic feasibility were presented. It shows that the thermal efficiency of the cogeneration has increased from 37.34% to 75.60% compared with the conventional approach. Steam and hot water production from the waste heat of 1 MW engine are 659 kg/hour and 8.54 m3/hour respectively. Thus, saving the boiler biomass-fuelled of the mill about 2,748 tons a year with a simple payback is 1.3 years.

The increasing number of private PV arrays calls out for high energy storage capacities in order not to overload the grid. Despite being the current storage technology of choice, chemical batteries are still too expensive and have certain disadvantages compared to FESS, such as capacity fade over time and currently still difficult recycling. Within a research project at the Graz University of Technology a feasibility study for a low-cost, low-loss FESS was conducted. Energetic dimensioning was performed using actual PV power and electric load data recorded at a building in Austria with 6 apartment units. A low-cost flywheel system with an energy content of 5.0 kWh and 2.2 kW maximum rated power using a steel rotor and economic off-the shelf components was designed and investigated. Self-discharge of the proposed FESS design was significantly reduced using a cast silicone bearing seat, which allows supercritical rotor operation. Axial bearing loads were compensated by nearly 100% via repelling permanent magnets allowing drastic down-sizing of the bearings and further reduction of torque loss. The concept was validated by a small-scale test setup, which showed promising results. Finally, an improved design option is compared to the initially proposed FESS in terms of costs and self-discharge.","PeriodicalId":149415,"journal":{"name":"2016 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126279385","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}
