Superconducting Magnetic Energy Storage (SMES) is adopted to auxiliary smooth the fluctuation of wind power and absorb the excess energy when grid voltage fault happens, thus stabilizing the DC bus voltage and balancing the output and input power. As for the LVRT control strategy, compared with the traditional PI control which the AC output signal cannot be tracked with zero steady-state error, Quasi Proportion Resonant Differential (QPRD) Control is proposed in this paper. Through designing the gain of the resonant point to infinite, the tracking performance of AC signal realizes zero steady-state error, and the overshoot and settling time is reduced. With the application of the proposed QPRD control in doubly-fed induction generator (DFIG) type WECS with SMES, not only negative sequence current is inhibited, but also the double-frequency oscillation in active power and DC bus voltage is suppressed .The feasibility and effectiveness of the proposed QPRD control for 1MW DFIG type WECS with SMES are verified through MATLAB/Simulink simulation.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131427217","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}

Among them, IPMSM (Interior Permanent Magnet Synchronous Motor) has more wide speed range in flux-weakening region than that of SPMSM (Surface Mounted Permanent Magnet Synchronous Motor) because of torque efficiency per unit volume and wide torque out range of IPMSM. Therefore, IPMSM is the most commonly used in the automotive industry as a motor for EV driving. In electric vehicle, the torque output is determined variably and instantly corresponding to the operation of the accelerator and the brake of driver. So, the torque transient periods whose torque reference is variable are generated very frequently in accordance with a variable speed. Therefore, in this paper, improving method of torque response in a transient period for electric vehicle is explained. The current reference of IPMSM is output using 2D-LUT. Also, in order to complement the disadvantages of PI controller of conventional field oriented control, the predictive current control is used, improving torque response at torque transient period.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122583886","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 proposed strategy determines whether a controllable switch should be turned on or not is based on the latest switch record of its corresponding upper or lower controllable switch in the same phase leg and its anti-parallel diode conduction state. This method only detects the lower anti-parallel diode conduction state in each phase leg for H-bridge PWM converters. Two controllable switches in the same phase leg are not needed to switch one after another by using this switching strategy. Dead-time is not needed even at the instant of the current polarity change. Therefore, dead-time can be completely eliminated. This method significantly solves dead-time effects in conventional PWM voltage source converters. The principle of the proposed switching strategy is described in detail. Simple logic equations that represent the switching strategy are presented. Simulation and experiment results using an H-bridge converter for passive loads are given to confirm the validity of this new switching strategy.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126398589","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}

It can overcome the limitation of abc to dq frame transformation. However, the D-Σ control requires four sets of control laws to cover four quadrant operations: grid connection (PF 1 ~ ±0.866), rectification with power factor correction, PF leading (0 ~ 0.866), and PF lagging (0 ~ -0.866). Moreover, the switching sequences for the four modes are also different from each other, increasing complexity of firmware programming. In this paper, improvement of the control-law derivation and region selection for the D-Σ digital control is presented. By selecting the zero crossing points of phase voltages as region transitions, the control laws and the related parameter tables for the four modes can be unified to a general form. The switching sequences of the four modes are also unified to the switching pattern of the grid-connection mode. Additionally, a D-Σ transformation matrix is identified to simplify the derivation procedure of the division (D) and summation (Σ), which can obtain the control law directly. Measured results from a 10 kVA 3Φ bi-directional inverter have been presented to confirm the improvement.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115057117","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}
