The dynamic model of the proposed topology is obtained and validated with a simple open loop simulation. A suitable linear master-slave control scheme is presented in order to ensure the current tracking and the DC voltage regulation.

The supercapacitor can effectively harness the regenerated electric power in the regenerating mode and discharge it in the motoring mode. By analyzing traffic flow model of elevators, a capacitance design method based on traffic flow difference is proposed in this paper, which can satisfy the elevator operational safety requirements and reduce the system cost. Then, control strategies of motoring mode, regenerating mode and malfunction mode are analyzed respectively by analyzing energy management strategy of DC bus voltage detection. Finally, an experimental platform of supercapacitor energy-storage type elevator was built. Experimental results validate that the system control strategy can effectively harness and allocate the harnessed energy.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129668649","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 second, passive part of the system is a set of inductors magnetically coupled in the system 18-pulse. Such a system is able to generate near sinusoidal output voltage without PWM operation - transistors operate at switching frequency close to output frequency.

Improving the extent of correlation between interharmonic and voltage fluctuation measurements 提高了间谐波和电压波动测量之间的相关性

Halpin","doi":"10.1109/CPE.2017.7915144","DOIUrl":"https://doi.org/10.1109/CPE.2017.7915144","url":null,"abstract":"Because the use of 60-W incandescent lamps is declining in parts of the world, voltage fluctuations' effects on other devices may need to be explicitly considered in international standards. The existence of international standards for measuring interharmonics and the mathematical relationship with periodic amplitude modulation has suggested interharmonics as a potential basis for broadly characterizing voltage fluctuations. But any novel approach for measuring voltage fluctuation needs to provide results consistent with present practices in addition to offering additional advantages. Therefore, the first step is demonstrating a general correlation between interharmonic measurements and currently accepted flicker severity measurements. The feasibility of demonstrating the correlation between these measurements has been explored in an earlier work. Using a magnitude-only custom interharmonic group it was concluded that measurements were strongly correlated in most cases. A closer examination of the flickermeter is made in this paper, and an improved custom interharmonic group is developed in view of a flickermeter's response to the combined effect of interharmonic pairs through phasor addition. This approach revealed strong correlation for every dataset examined. It is concluded from these results that interharmonic and lamp flicker measurements are strongly correlated in general.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459425","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}

Conventional controllers are based on linear regulators such as PI and PR. This paper proposes a model predictive algorithm based on PNSC reference generation method to control the 3L-NPC inverter under grid voltage sags. The novel algorithm allows the easy inclusion of system nonlinearities, thus no additional fine tuning parameters are required. Moreover, no additional phase-locked loop synchronization technique is needed, reducing system complexity. A SOGI filter is added for voltage sequences extraction. The overall discrete model of the system is developed. Two-step horizon MPC algorithm is introduced for time delay compensation. Simulation results show the advantages of the proposed technique in terms of low harmonic line current content, low switching frequency operation, DC voltages balancing, good dynamic response and robustness to grid sags.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126214072","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}

Inverters are prone to several types of faults e.g. switch failure or dc link capacitor failure. Failure mode analysis of cascaded H-Bridge is widely discussed in the literature. Various methods for post-fault operation with reduced capacity (due to module failure) but with balanced three-phase grid current has been proposed. Quasi Z Source Inverter with its unique capability of boosting the input voltage has become quite popular in solar PV applications. Implementation of Multi-level qZSI for grid synchronization has also been proposed. In this paper, control algorithm for the operation of Multi-level qZSI with module failures (up to three modules out of total 16) is discussed. The power deficit due to a failure of the module is reflected as a decrease in the grid current reference. The grid current injected will meet the THD requirement (< 5% THD) in the post-fault condition. To verify the proposed control algorithm, simulation results are presented and discussed.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128918778","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}
