The inverter prototype is a 2-level voltage source inverter, and the whole system is cooled by force air. In this inverter prototype, we integrated a DC voltage sensor and three AC current sensors with the main circuit. We applied thin-film capacitors paralleled to decrease stray inductance of main circuit to nearly 10nH. The volume of the prototype system is about 9.3dm3 and the weight is about 36.25kg. Experimental performance shows that the rated output power of the prototype inverter can up to 132kW, which is larger than the conventional IGBT inverter by 18.2%. In this case, the power density of the proposed inverter is 14.19kW/dm3 or 3.64kW/kg and the efficiency of which can up to 98%.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129332254","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 predictive method is based on examining the feasible voltage vector in a prescribed cost function. The voltage vector that minimizes the stator current error in the cost function is selected. An advanced model predictive current control is proposed to solve the problem of system noise amplification in the differential link caused by the current slope calculation in the back electromotive force model (EFM). The predictive model includes the sliding mode feedbacks which are employed to observe the real-time rotor speed and flux linkage. Besides, the feedback gains satisfy the Lyapunov's law of stability. In order to verify the fine dynamic and static performance of the proposed method, simulation and experimental results are presented.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127894152","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}

Timely detection of minor faults and early warning are conducive to the safe operation of units. With the large-scale deep variable load of units, the operating conditions of auxiliary equipment also change in a large range, and the operating parameters fluctuate in a large range, which directly affects the accuracy of fault early warning algorithm based on operation data. In order to solve this problem, this paper uses a multivariate state estimation technique (MSET) algorithm for fault early warning. Firstly, the cluster method is used to divide the operating conditions of units, and process memory matrix is constructed under different operating conditions for modeling and calculation. The simulation results show that compared with the traditional method using one process memory matrix this method significantly improves the accuracy of fault early warning.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"90 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126025637","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 netted multiterminal DC distribution systems, system circulating currents often occur because of the different positive and negative line parameters. In this study, the steady- state equivalent circuit model of four-terminal grid DC distribution system is established, and the mathematical expression of system circulation is theoretically derived. The variation characteristics of circulating currents caused by inconsistencies of positive and negative circuit parameters are quantitatively analyzed. The adverse effects of the system circulating currents on the operation and protection of the DC distribution system combined with the possible parameter changes in the actual power network are analyzed.

The model is solved using an MILP tool to minimize the net present cost for a long-term operation with multi-year investment option in order to address the performance degradation of the DERs. The simulation results show reduction of the initial capital costs when compared to typical models.

Coal was initially divided in two different bunkers based on its quality. The big bunker was filled with LRC and the smaller one was filled with MRC. To observe further impact on boiler performance, four different flow ratio percentages were set up through the coal feeder. We found that increasing the MRC ratio contributed to the rising furnace bed and inlet cyclone temperature. This also positively affected the boiler efficiency with the highest value of 86.77 % with full of MRC. However, the co-combustion caused drawbacks due to inhomogeneous temperature distribution within those furnaces. The average bed temperature ranged from 974 0C to 1,000 0C.

Simulation using Matlab/Simulink tool and Hardware-software co-simulation using Xilinx system generator is performed to analyze their performances. Among these three, Type III compensator is proposed which gives the best performance under wide load current and input voltage variations in terms of undershoot and response time. With type III compensator, a settling time in the range of 11-15 μs and maximum peak overshoot in the range of 2-8% is obtained for load variations and settling time in the range of 13-15μs and maximum peak overshoot in the range % of 2.2-4.5 % is obtained for line variations.

In a phase-leg configuration, the SiC MOSFET can be operated under high switching frequency and high temperature with high voltage and current, in which case, the biggest challenge for SiC MOSFET is the electromagnetic interference (EMI). To utilize the full potential of SiC MOSFET and suppress the switching ringing as much as possible, this paper investigates the causes of switching ringing and proposes some suppression methods. Common suppression methods include increasing gate drive resistance, gate source shunt capacitance, and gate reverse turn-off voltage.
