In the existing studies, all the reconstruction methods are based on conventional motor. And the reconstruction precision is largely affected by the dead zones. For the purpose of improving the DC voltage utilization and fault tolerant capability, in this paper, a phase current reconstruction technique based on five phase open-end winding permanent magnet synchronous motor (OW-PMSM) is proposed by measuring the DC link current. Four nonzero and one zero voltage vector combinations are used to estimate the currents. A simple phase shifting method for the pulse width-modulated (PWM) signals is proposed so that the complex work of phase shifting in different sectors of five phase motor is avoided. The effectiveness of the proposed method is verified by simulation.","PeriodicalId":115174,"journal":{"name":"2020 International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"25 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127231749","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}

In order to overcome the influence of light variation or shooting angle, we propose a method of platen state recognition based on improved K-means algorithm. First, holomorphic filtering enhancement and perspective correction are performed on the collected platen images, and then the platen areas are divided equally according to the number of rows and columns of the platen. Secondly, the improved K-means algorithm is utilized to segment the platen image. Analysis to determine the status information of the pressure plate. In addition, we also conducted an experimental comparison to compare the algorithm with RGB threshold segmentation and traditional K-means clustering segmentation results. The experimental results demonstrate that the improved K-means algorithm significantly improves the accuracy of the segmentation of the platen image; and the recognition rate of the platen state reaches 99.6% by the algorithm of this paper.","PeriodicalId":115174,"journal":{"name":"2020 International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132083643","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}

Taking an AUV with a torpedo exterior as an example, a heading attitude controller is designed. In simulations conducted for comparison with a traditional PID controller, the proposed DO-based variable integral PID controller shows better tracking and robustness in the presence of interference.","PeriodicalId":115174,"journal":{"name":"2020 International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133578558","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 very weak grid performance during the dry season is presented and the interactions between energy use and grid operating practices are investigated. The results are given for eight households, trialling four types of electric cookers, in order to reduce firewood use. There is considerable interaction between the electric cookers and the power system. The effects of the power system and the electric stoves on the cooking preferences is also revealed. The addition of electric stoves during the evening cooking hours lead to an increase in the frequency of short power outages causing major interruptions while cooking.","PeriodicalId":115174,"journal":{"name":"2020 International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133354879","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}

To solve this problem, a new day ahead economic dispatch model based on the theory of bi-level planning is proposed. It fully considers the independent operation characteristics, economy and low carbon of the transmission and distribution network, and generates the day ahead economic dispatching strategy of the transmission and distribution network. The model is divided into two layers: the upper level, which aims at the operation cost of transmission network; the lower level, which aims at the distribution network operating cost and low carbon. In the optimization process of the upper and lower levels, the power interaction relationship of transmission and distribution networks is introduced into the solution process in the form of a penalty function to realize decentralized autonomy and collaborative optimization of transmission and distribution networks. The simulation results show that the scheduling plan generated by the proposed model takes into account the generation resources of the transmission and distribution grid, which is helpful to improve the economy and low carbon of the grid operation.","PeriodicalId":115174,"journal":{"name":"2020 International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131918060","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}
