To improve the operation performance of the motor, a method of space vector pulse width modulation (SVPWM) with fault-tolerance is proposed. The winding terminal connected to the bad leg is connected to the DC-link mid-point of the inverter. Then the motor fed by the five-leg inverter can get 32 stator winding voltage states, corresponding to 32 basic vectors which are all zero vectors in the 01-02 plane. With the 32 basic vectors, by using an optimal model four intermediate vectors are constructed which are all zero vectors in the $z_{1^{-}}z_{2}$ plane. The four intermediate vectors and some equivalent null vectors are used for synthesis to make the synthesized result track a desired vector. Experimental results show that the stator currents, electromagnetic torque and rotor speed of the proposed method are better than those of the sixphase SVPWM without fault-tolerance.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116305561","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}

However, the no n-convex and non-linear energy flow model of the heating network in this mode brings a huge challenge to the solution of the system scheduling model. To address this problem, a linear heating network energy flow model is first derived based on the assumption that the heating temperatures at load nodes are very small differences. Then, a first-order thermal load model considering the equivalent load generated by the fresh air system and the thermal inertia of the building is established according to the heat conduction process of the building and Fourier's law. Finally, a joint dispatch model for combined heat and power systems under variable flow control strategy is established. The validity of the model is verified by a 6-bus electric power system (EPS) and 6-node district heating network (DHN).","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124032613","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}

But can achieve the goal of reducing chattering and improving anti-disturbance performance. Then, a current controller based on improved proportional resonance is proposed.

Due to the characteristics that the inductance parameters vary rapidly with the currents, while the stator resistance varies slowly with the winding temperature, the RLS algorithm with a faster convergence rate is proposed to identify the inductance parameters quickly, and based on the RLS identification results, the LMS algorithm with less calculation is used to update the stator resistance. This method avoids the effect of using fixed parameters to identify the other parameters, and it can follow the changes in motor parameters well.

Mechanical faults are the main reason of the malfunction of circuit breaker. In order to diagnose the mechanical faults of circuit breaker, in this paper, the Mel Frequency Cepstrum Coefficients (MFCC) of the closing sound signals of circuit breaker are extracted based on the characteristics of human hearing. Then the Kernel Principal Component Analysis (KPCA) algorithm is applied to reduce the dimension of MFCC. The dimensionality reduction results of MFCC are taken as the feature vectors of closing sound signals. Sparse Representation Classification (SRC) algorithm is used to recognize the feature vectors. Meanwhile, the concept of scatter in Linear Discriminant Analysis (LDA) is applied into the objective function of SRC to improve the performance of SRC. Experimental results show that the method proposed in this paper can identify the circuit breaker mechanical faults accurately. MFCC could reflect the difference information of various mechanical states properly. Compared with SRC, the improved SRC algorithm that takes the with-class scatter and between-class scatter of the representation coefficients of feature vectors into account has better recognition performance. The identification process could provide theoretical guidance for field applications.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132094486","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}
