Hydropower is a renewable energy as very clean source energy. Especially small hydropower, the renewable energy which still has large potential and low cost of installation. Micro hydro turbine is an alternative technology for electricity generating that does not cause pollution from small hydropower. The crossflow turbine was studied experimentally in this project because of it is low cost, small sized, the materials used in construction are cheap and the technologies involved are conventional. At testing of micro crossflow turbine with 0.6 meter diameters of wheel and a 20 blades water turbine which has a semi-circle shape at 0.1 meter diameters of blade, connected with generator at gear up ratio of 1-3 and 1-5 respectively, was undertaken. The results from the test run of crossflow turbine by varying flow rate from 60 to 120 L/min at 0.0127, 0.0190 and 0.0254 meter diameter of nozzle respectively, showed that at water flow rate 120 L/min, 0.017 meter diameter of nozzle and gear ratio of 1-3 give the maximum electric power of 121 watts at generator speed of 468 rpm.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127165882","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}

Partial discharge (PD) is a well known phenomenon that causes insulation degradation in cross linked polyethylene (XLPE) power cable and ultimately it will cause insulation failure. The research shall involve ISE Simulator version 10.1i (Xilinx) and ISE Xilinx Synthesized Technology (XST) using Very high integrated circuit Hardware Description Language (VHDL) programming to evaluate the use of Field Programming Gate Array (FPGA-Xilinx Virtex 5 ML501 Board) for the detection and counting of partial discharge signals in high voltage underground cable. The impulse signals at the input data have very fast rise time in the field can have a bandwith of about 200 - 600 MHz. The output signals of the combination 4 blocks (peak detector block, 64 bit BCD counter with reset block, reset automatic block and 64 bit BCD counter) is processed using reset automatic block and 64 bit latch block for keep output data in LCD to constant when the 64 bit BCD counter block is reset and return to zero again until update new data again. The combination of all blocks of PD detection circuit system is tested by using Xilinx ISE simulator and implemented by ISE Xilinx Synthesized Technology and Xilinx ISE Implement Design.

Accelerated starting by motoring a grid-connected small wind turbine generator 通过驱动并网的小型风力涡轮发电机加速启动

With appropriate switchgear and control, it should be possible to use grid power to operate the generator as a motor for faster starting of the turbine. The artificial case of a step increase in wind speed from zero is considered. It is shown that motoring yields an energy gain for all wind speeds typical of the operating range of small turbines. This paper proposes short-period motoring of a permanent magnet generator in a 5kW wind turbine system connected to the grid with a backward very sparse matrix converter which has bidirectional power flow capability. Motoring produces torque in the same direction as the aerodynamic torque on the turbine which in turn accelerates the turbine more quickly towards the maximum power point. Interestingly, the overall result is that more energy is delivered to the grid by short-term motoring than in the case where the turbine is accelerated aerodynamically without motoring. In the proposed system, the very sparse matrix converter controls the generator torque through field orientation where d-axis current is set to zero while the q-axis current is used to control the generator torque and thus control the turbine speed in both motoring and generating modes. The switching signals of the converter are formed based on the principle of space vector modulation. Simulation results, with and without an electromagnetic starting torque, indicate that the proposed technique increases the overall energy efficiency of small wind turbine systems while providing fast starting.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116600129","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}

A 630 MVA, 400/220 kV substation was identified and a detailed study was carried out to assess the various station performance parameters under different operating conditions. It was observed that the installed capacity of the station (transformer) was very large compared to the actual load it had to supply. Thus the station was under loaded and underutilized for the major period of its operation. This reduced the operational efficiency of the station. Secondly the incoming line voltage level was remaining high during most of the period of operation. Presently voltage is tried to be maintained by switching ON the line reactors at the receiving and sending ends of this station, switching OFF one of the 400 kV incoming lines during off peak loading conditions, thus risking the supply reliability. The present study emphasizes on the urgent need for improving the power quality, streamlining and optimizing the station capacity, operations and its loading pattern. Accordingly suggestions are proposed for the same.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116636143","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}

Two way commutations are key to making the grid smarter. The smart grids refer to system that can communicate data back and forth between a utility company and a customer. The wireless communication and antennas that utilize RF signals are often best suited to facilitate this grids communication. This antenna based on modern MIC and MMIC fabrication technology is used to develop a compact light weight, small size, high performance and low cost active antenna. The proposed antenna is designed to radiate and transmit equal amounts of power. The return loss of the proposed antenna is higher than that desired for one-port antenna application at the desired dual-band frequencies. The antenna generates two separate frequency resonant modes cover to cover 2.45/5.2Ghz. The antenna is fabricated on one side of a Neltec substrate with εr =3.2 and thickness= 0.762 mm, and the microstrip feeding line is fabricated on the opposite side of the board. The antenna is designed to operate at WLAN bands centered at 2.45 and 5.2GHz. The simulated and measured results show fairly good agreement.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121769669","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}
