While laboratory testing methods are the predominant method for the verification of safety and quality related features of grid-connected generation units in the past, load flow modeling verification methods have been integrated in state-of-the-art standardization frameworks recently. The next step is comprised in real-time simulation methodologies applied for compliance testing of entire power electronic systems integrated in power distribution networks. The Controller Hardware-in-the-Loop (CHIL) approach is an appropriate methodology that combines numerical simulations with software modeling approaches and classical hardware testing in labs. Control boards represent the hardware device directly connected to the power electronic periphery, which is entirely simulated in a real-time simulation environment. Hereby, input signals from voltage and current measurements and output signals for power system control are exchanged in real-time. Thanks to this setup the testing of the true behavior of entire generation units within the electric network can be emulated precisely. With the application of CHIL a shorter time to market and a lower risk in the development phase can be achieved. However, an analysis from realized CHIL experiments shows the need for more harmonized procedures. This paper addresses this topic and provides an outlook about necessary future CHIL standardization needs.","PeriodicalId":146951,"journal":{"name":"2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130738244","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}

By establishing the mathematical model of the HERIC type inverter which is proved to be a mainstream transformerless PV inverter, the result for causing the ZCD is presented. To suppressing the ZCD while achieve high efficiency and reactive power capability, a hybrid unipolar pulse width modulation (UP-PWM) is proposed. The proposed method adopts grid frequency unipolar pulse width modulation (GFUP-PWM) when outputting active power. While generating reactive power, the leg switches are all closed, and only the freewheeling switches work at high frequency. Aiming at reducing the ZCD, a modified high frequency unipolar pulse width modulation (HFUP-PWM) is proposed near the voltage and current zero-crossing point (ZCP) regions. And the duty cycle is adjusted to compensate the narrow pulse limit and dead zone in HFUP-PWM. The proposed scheme has high efficiency and good power quality while provide reactive power support. Finally, the effectiveness of the proposed modulation scheme is verified by the simulations results based on a 4-kW inverter at 20-kHz switching frequency.","PeriodicalId":146951,"journal":{"name":"2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126766203","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}

Multi-loop controller are adopted to gain good dynamic performance, while a plug-in modified repetitive controller is proposed to achieve zero steady-state error for sinusoidal reference. In addition, in order to solve the contradiction between stability and control performance of the repetitive controller, the relationship between control performance and robustness is elaborated, and the optimization method of repetitive controller is presented, which increased the freedom to design the compensator. The stability of overall system has been analyzed and the explicit optimization procedures of repetitive controller have been proposed. Simulation and experimental results confirm that the proposed strategy offers good-quality sinusoidal voltage with nearly zero-steady state and low total harmonic distortion (THD) under different load conditions.","PeriodicalId":146951,"journal":{"name":"2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"309 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131801672","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}

An arc model of a circuit breaker can determine the dynamic and static feature for arcing directed by a power circuit. The idea of HTS Circuit Breaker (HTSCB) evolves with the concept of HTS contacts in liquid nitrogen arc medium. Browne's HTS arc model for HTSCB and its characteristics were developed and investigated earlier in order to address the arcing limitations of existing circuit breakers for HTS power applications. The model was mainly developed from the classical arcing equations. In this paper, the same arc model is investigated for the functionality of arc characteristics simulation response. It is found the arc model has closed relationship with time constant, reference voltage and other parameters. The parameter sweep technique for minimizing the arcing time of HTS arc model parameters shows the trend of arcing voltage and current from the change of arc model's parameters. A test bed environment is developed in MATLAB® Simulink by using the final parameter values to perform the interruption scenario of HTSCB. The results deal with different arcing terms like arc current peak, arcing time, fault duration, transient results of HTS arc model and the wave form transition tendency. Finally, the results are compared with the experimental analysis and found in good agreement.","PeriodicalId":146951,"journal":{"name":"2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131667755","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}
