The efficiency of the traditional gear reducers (66%-76%) is too low to run in the elevator, so the energy saving and reproduction technology with high efficiency is instead. The design objectives of PMSGM face torque density, efficiency and torque ripple questions. This paper presents new optimization design methods for the multi objectives. The pole shape optimization based on Taguchi method provides the key factor analysis between those objectives, then proceeds the one factor optimization method to obtain the solution. Finally, the protocol type of the motor, the 3.0 KW PMSGM is made. The performance and parameters of the motor is obtained under the load. The efficiency of the motor is near 92% and meets the design goal. The key parameters of the motor are obtained, such as d-axis reactance, q-axis reactance, resistance, and flux linkage. The field results about the new motor are closed to that of the simulation. Spatially, the lower total harmonics distortion (THD) shows that the motor will provide a good performance of the implementation about the torque ripper.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131254148","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}

Where appropriate resources exist, pico hydropower is a cost effective method of electrical generation, especially in a rural context. For pico hydropower at low heads, propeller turbines are traditionally used. However, these are very site specific and the efficiency dramatically reduces when not operated at rated conditions. This paper derives six key experimental parameters for a Turgo turbine using two-dimensional fluid equations, which are experimentally varied to find the affect on the efficiency on a scale prototype, obtaining a design that is optimised for efficiency. Test results are presented up to heads of 3.5 m. It is found that the turbine efficiency is very sensitive to jet vertical aim position, with the optimum aim at 12 mm from the top of the cup with a jet inclination angle of 20°. The nozzle diameter is found to have a critical value of 20 mm, above and below which the turbine efficiency reduces. The turbine wheel diameter is reduced from 7.5 times to 5 times the nozzle diameter with minimal effect on the maximum efficiency, however, this provides an increase in the rotational speed from 490 to 750 RPM. The maximum experimental jet-to-mechanical efficiency is found to be over 90% for the scaled turbine, with lower sensitivity to head and flow rate than propeller turbines. This demonstrates that Turgo turbines can be used efficiently at low heads over a range of site conditions.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133681832","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}

Low Voltage ride through (LVRT) capability is required by new power system operating codes. At the same time, the sudden change of the grid voltage is a shock for wind turbine. Fast and accurate detection of grid voltage sudden change fault is an important condition to achieve safe operation of the power grid and LVRT of wind power system. This paper fully analyzes the existing voltage sudden change detection method and presents a method of comparing the instantaneous value of test signals with the instantaneous value of “standard sinusoidal digital signal”. It generates the standard signal with the same frequency and phase as the test signal by Phase Locked Loop (PLL) technology. It gets values of test signal at some point in a cycle by the digital signal processing technology. Then, the difference between each present value of test signal and its corresponding “standard sinusoidal digital signal” values is used to reflect the real-time status of the signal under test. This instantaneous value comparison method can accurately and without delay detect the sudden change of voltage (sudden drop or a sudden jump in) and the computing is small. In order to ensure the accuracy of the detection without changes in grid frequency, but also from the impact of voltage sag depth, we improve the PLL signal input circuit. The fast and accurate detection of the grid voltage sudden change supplies the timely and accurate condition for wind turbine to through the low voltage.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130865934","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}
