Nevertheless, they are expected to become an important element also in the monitoring of the dynamic and complex scenario of the future smart distribution grids. The IEEE standard C37.118.1 defines the measurements, the indices and the methods to evaluate synchrophasors, frequency and ROCOF (Rate Of Change Of Frequency) under steady-state and dynamic conditions. The compliance to this standard ensures the interoperability between the PMUs provided from different vendors. The test signals defined in the standard C37.118.1 mainly reflect operating conditions that can occur in the transmission networks. On the other hand, the electrical signals that can be measured in the distribution networks may be different and these different scenarios should be kept into account when a PMU is purposely engineered for the needs of the electric distribution grids. Several international standards describe the voltage characteristics of electricity supplied by distribution systems and consider some operating conditions that are not included in the synchrophasor standard. The aim of this paper is to highlight, through an appropriate test setup, the performance of the PMUs under one of such unexpected conditions, namely the voltage fluctuations that give rise to the disturbance commonly known as light flicker.","PeriodicalId":290041,"journal":{"name":"2016 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131977013","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}

This statement is definitely true when amplitude, phase, frequency and rate of change of frequency (ROCOF) fluctuate significantly within the observation interval used to estimate them. Unfortunately, these estimation algorithms can be very sensitive to narrow-band disturbances, unless these contributions are explicitly included in the model at the expense of a larger computational complexity. However, if the observation intervals are so short that the waveform parameter variations each of them are minor, then algorithms based on static phasor model can provide accurate results with a reasonably low computational burden. Since the waveform fundamental frequency is a key parameter for power systems monitoring and control, in this paper the estimation accuracy of three classes of state-of-the-art algorithms based on a static signal model is analyzed and compared when only few waveform cycles affected by both steady-state disturbances (e.g. harmonics) and amplitude or phase oscillations are collected.","PeriodicalId":290041,"journal":{"name":"2016 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133662689","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 IEEE Standard C37.118-2011 and its amendment (IEEE Std) describe compliance tests for static and dynamic conditions, and indicate the relative limits in terms of accuracy. In this context, the paper focuses on the definition and accuracy assessment of the reference synchrophasors in the test conditions dictated by the above IEEE Std. In the first part of the paper, we describe the characterization of a nonlinear least-squares (NL-LSQ) fitting algorithm used to determine the parameters of the reference synchrophasors. We analyse the uniqueness and robustness of the solution provided by the algorithm. We assess its accuracy within the whole range of static tests required by the IEEE Std. In the second part, we discuss the appropriateness of synchrophasor model to evaluate the PMU performance in step test conditions. We compare the proposed algorithm against two synchrophasor estimation algorithms. Finally, we propose a time domain process for the better evaluation of PMU performances in transient conditions.","PeriodicalId":290041,"journal":{"name":"2016 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131980356","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}
