Within the variable-speed solutions, the one employing a doubly-fed induction generator (DFIG) has become the preferred solution for large installations since it provides the advantages of variable-speed operation and four-quadrant active and reactive power capabilities using converters rated only a small fraction of the rated power. A deep understanding of the characteristics of the fault current fed by a DFIG after a three-phase short-circuit at its terminals is of utmost importance to define the requirements of the generator circuit-breaker (GenCB) to be installed between the generator and the step-up transformer. The only standard which covers the requirements for GenCBs is IEEE Std C37.013-1997 (R2008) with its amendment IEEE Std C37.013a-2007; which will be soon replaced by the IEC/IEEE Joint Development IEC/IEEE 62271-37-013. The requirements laid down in this standard are based upon applications employing synchronous generators. The question whether these requirements are adequate for the application of GenCBs in pump-storage power stations employing DFIGs is considered in the present work.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312963","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 control objective is to improve the SMIB stability by bringing the system from a perturbed state to the equilibrium state and keep it there. The purpose of using NMPC is to handle the nonlinearity of the model and to satisfy the imposed constraints.

The de-coupled control of stator flux and output torque based hysteresis band controller which implemented in conventional DTC system is applied to retain the simplicity of this system.

This topology is developed based on a very sparse matrix converter with addition of a leg in the inverter stage, which can reduce the amount of power transistors compared to the conventional dual matrix converter system and; therefore, can achieve the realization of highly compact ac drives. A control strategy for the system, which combines vector control technology for loads and the space vector pulse width modulation (SVPWM) algorithm for a matrix converter with a four-leg inverter, is proposed. The proposed control and modulation schemes guarantee sinusoidal input/output waveforms and bidirectional power flow. Finally, the proposed system and independent control algorithm are verified by simulation using the very sparse matrix converter, which is implemented with 14 IGBT switches and 32 diodes connected to a three-phase and single-phase loads.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130942218","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 overcome those obstacles, we propose the cost effective and secure service platform with mobile backhaul network. Our proposal applies the RoF based CBS (cloud base station) for cost effective mobile network. The RoF based CBS reduces a CAPEX and OPEX for optical link to build up a next mobile network since it can reuse a present optical link or minimize the number of new optical link. We propose the TPHE (Two Phase Hybrid Equalizer) to overcome the technical issue which is distorted the analog signal on optical link. The TPHE has improved 3.0% of measured EVM. Our paper proposes the WSTA (Wi-Fi based Security Tunnel based on Application) for the BGW (Backhaul Gateway) which connect to mobile backhaul network and Wi-Fi. The WSTA manages security tunnels and pipe to overcome the security vulnerability point on Wi-Fi. The WSTA can protect the other security pipe or tunnel except the hacked pipe or tunnel from hacker even though a specific security tunnel or pipe has hacked, since a security tunnel or pipe is independently managed with the other security tunnel or pipe. A security tunnel is managed by application and a security tunnel is tied to the security tunnel.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535067","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}
