The proposed system works by directly cooling the CPU on each server. To uniformly remove the heat from the CPU surface, the heat sink has been redesigned with heat pipes to transfer the heat to water channels which results in a more efficient cooling system. Thus, less water will be needed than a traditional liquid cooling system. This makes the new system more ecofriendly and cost effective. Furthermore, a smart android-based temperature control model is incorporated to adjust the water flow rate of the cooling system and remotely monitor the thermal condition of the CPU. A data acquisition system is utilized to capture the thermal status of the CPU. Accordingly, a digital pulse width modulated switching signal is generated to control the supply voltage of the pump in order to optimize the water pumping power. Thus, the overall efficiency of the proposed cooling system is significantly improved compared to other conventional cooling systems.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131326627","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, transformerless inverters with conventional topologies suffer from leakage current problem which needs to be handled carefully. In order to overcome the conduction loss and leakage current problem associated with conventional transformerless inverters, a new transformerless H6 (6-switch-based) inverter topology is proposed in this paper that can maintain constant common mode (CM) voltage while reduce or eliminates the leakage current problem. The proposed inverter topology is simulated using MATLAB/Simulink software to validate the accuracy of the proposed system. The effectiveness of the proposed topology is verified through the comparative results of CM voltage, CM leakage current and conduction loss of the proposed topology with the conventional H6-I, H6-II and H5 topologies. Finally, to validate the proposed topology, a laboratory prototype is also built and tested. The experimental results validate the theoretical analysis and simulation results.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121107206","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 improve the overall efficiency of the system, this paper proposed the overall efficiency model of the system and designed an energy management strategy (EMS). The proposed EMS includes two power allocation modes of charging and discharging of the system, which can realize the allocation of the load power according to the system operating conditions and the overall efficiency. In order to prove that the proposed EMS can allocate load power according to the optimal overall system efficiency under any operating states of the fuel cell (FC) EV, a hardware-in-the-loop (HIL) experimental platform was established. Through HIL experiments, it can be proved that the proposed EMS can not only ensure the stability of the bus voltage under input and load disturbance but also maintain the lithium battery state of charge (SOC) within the safety range.

The steady state analysis of the machine is performed under the Stator Inter-turn Faults (SITF) conditions which give rise to stator phase currents. The consequent effect of high rise in stator currents has an adverse effect on the surface mounted rotor PMs of grade N35SH having a non-linearity characteristic depending upon the operating temperatures. The change in temperature (∆T) is function of stator phase currents which alters (δ Is) and increases drastically under SITF conditions. Consequently, the rotor PMs demagnetizes, and the Partial Demagnetization (PD) condition commences. The Finite Element modeling of possible demagnetization fault cases under different current intensity (to imitate SITF) are studied. The adverse effect on the motor back-EMF (EB) and magnetic flux (BM) signatures are investigated which are used as fault indicators. The proposed study has the ability to determine the partial demagnetization state at its incipient stage post the SITF conditions.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131060473","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 presented digital differential protection is developed to comply with the Standard ANSI 87T, and has its differential currents created by dq0 components of the currents flowing in the high and low voltage sides of a SST. Internal faults are detected and identified based on energy contents of the high frequency sub-bands present in the dq0 differential currents. Desired high frequency sub-bands are extracted using the phaselet transform, which can process signals without sensitivity to variations in their frequency and/or phase shifts. Energy contents of extracted high frequency sub-bands allow accurate, fast, and reliable detection and identification of faults in any part of a SST. The developed digital differential protection is implemented for performance testing using a laboratory 25 kVA 3ϕ SST. Performance results demonstrate accurate, fast, and reliable response to different fault and non-fault events. Responses of the developed differential protection are found to be insensitive to the fault type, fault location, and loading level.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134480771","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}

Therefore, intermittent solar PV power generation and uncertainties associated with load demand are required to be accounted to gain a holistic understanding on power grid voltage stability with high penetration of PV energy sources. This paper presents a framework for power grid voltage stability analysis considering uncertainties associated with PV power generation and load demand using Monte Carlo simulation. Commonly used voltage stability indicators such as critical eigen value, line loss, reactive power have been considered in the proposed framework. The proposed methodology has been verified by analysing voltage stability of IEEE 14 bus test system, with high penetration of PV energy sources and considering uncertainties associated with load demand. The results provide a clear insight to voltage stability of power grid with different penetration level of PV energy sources into the power grid.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131259531","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 assessment and characterization of the wind and the wave resources are carried out in terms of the wave power flux, the wind power density, the wave mean directionality and the other related parameters. The wave energy conversion technology requires a more detailed investigation as compared with that of the wind technology because of its variability in terms of the size and the operating principle for each technology. The power performance comparison is made for six commercial wind turbines with different rated power. Six pre-commercial wave energy conversion technologies are evaluated for their power performance and the hydrodynamic performance in terms of capture width ratio.
