Due to the widespread use of synchrophasor measurements, it becomes necessary to characterize each PMU based on their performance and select the appropriate device for the required application. Furthermore, the IEEE Std C37.118.1a-2014 mandates the latest performance standards for the commercial PMUs and classifies them based on their performance. This necessitates the development of a test-bed which is capable of testing different PMUs to check whether they comply with the latest IEEE standard and also to characterize the devices in terms of their accuracy and precision. This paper describes a LabVIEW based PMU testing and calibration system that was developed at Virginia Tech with the support of NIST and is capable of performing the latest steady state, dynamic and latency tests as described in the IEEE Synchrophasor standard. The testing system also provides flexibility by automatic and manual modes of operation to allow the characterization of PMUs based on the requirements of the test operator.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126230588","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}

When power grid is stressed as a result of failures due to natural disasters and attacks (e.g., High Altitude Electro-Magnetic Pulse (HEMP) and Weapons of Mass Destruction (WMD's)), successive interdependent failures may propagate within and across these networks leading to large-scale cascading-failures and blackouts. Failures in power grid can affect the communication network, which in turn, may affect the power grid, and so on. In this paper, we study the influence of communication network functionality on the power grid. Specifically, we analyze the impact of such interdependencies on the reliability of the power grid by capturing the influence of the communication network on the power grid during cascading phenomenon. Two critical topological parameters of the communication network are studied, namely the hop distance and the node degree, which are used to determine the coupling parameter between the two systems and to quantify the influence of communication network in the power grid. Finally, numerical results has been carried out to quantify the impact of communication network failure on power grid reliability and validate our proposed model.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121620171","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}

Furthermore, it allows the integration of geographically distributed assets as Power Hardware-in-the-Loop and Controller Hardware-in-the-Loop, thus providing a flexible framework for performing unique research experiments. In most cases, it is not possible to perform large scale real-time simulations and comprehensive experiments locally due to lack of simulation capacity and unavailability of unique assets. Main challenge associated with geographically distributed real-time simulation is to ensure simulation fidelity of the same degree as in the case when the entire simulation is performed at the same location. Simulation fidelity in geographically distributed real-time simulation is investigated and an empirical characterization is provided in this paper. Fidelity degradation caused by different values of time delay and sending rate of data exchange between two digital real-time simulators is presented. Two methods for representation of interface quantities in co-simulation interface algorithms are considered for performing simulations. The first method is based on representation of interface quantities as root mean square of magnitude, frequency, and phase angle of the current and voltage waveforms. The second method utilizes representation of interface quantities in form of time-varying Fourier coefficients, known as dynamic phasors. The empirical study is performed for transmission-distribution co-simulation using two racks of Real-Time Digital Simulator (RTDS®).","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131139402","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 feeder cable of this type of arrangement produces additional stresses on the windings. This paper proposes an optimized filtering technique to mitigate the transient overvoltages and reduce the associated stresses. Multi-objective optimization algorithms are used to find the parameters of an RLC filter that minimizes the objective functions (rise time, setting time, and over shoot) in the output voltage. For that purpose, a non-uniform transmission line model of the machine winding is used to predict the transient voltage propagation along the machine winding. The winding parameters are computed using the finite element method. The feeder cable is included by means of a distributed parameter model whose parameters are obtained from measurements. The simulation results are validated by means of measurements on an experimental cable-coil setup. Finally, the optimal filter obtained from simulations is physically constructed to test its performance on the experimental coil.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131904130","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 interest in grid-tied PV transformer-less inverters has increased rapidly, because of their higher efficiency and lower cost compared to traditional line transformer inverters. In this paper, a new modified transformer-less topology derived from H5 inverter is proposed. The proposed topology is equipped with GaN HEMTs to fully benefits from the superior performance of WBG devices. Detailed operation modes, inverter structure and switching strategy of the proposed topology are investigated and compared to conventional H5 topology. Furthermore, a comparison of the performance of the proposed inverter with Si IGBT and GaN HEMTs was presented to analyze the benefits of using WBG devices. The simulation results validate the theoretical that the proposed topology reduces the conduction losses of the system. The simulation results show that GaN HEMTs based inverter provides lower power losses and more than 5% increase in the efficiency when compared to Si IGBTs based inverter. Thus, prove the effectiveness of the proposed inverter for grid-tied PV applications.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127419874","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}
