The constraints that must be fulfilled by the voltage wave supplied by utility companies have become more and more exigent. For this reason, the PQ measurement equipment requires new and computational efficient algorithms. This paper presents a Discrete Wavelet Transforms (DWT) based triggering algorithms for PQ measurement instruments. Some typical PQ disturbances (sags, spikes or harmonics) have been considered to define figures of merit that can detect the presence of such disturbances and therefore are suitable to trigger the data recording of the PQ analyzer. All these figures of merit are obtained from the DWT decomposition. The final validations of the triggering algorithms have been done with real measurements.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114948382","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}

For transient or aperiodic signals the Fourier analysis is unable to obtain accurate results and a joint time-frequency analysis must be used to provide simultaneous time and frequency information of transient intervals. A power quality index is proposed for evaluation of both the stationary and transient quality aspects of electrical signals. The widely used total harmonic distortion index (THD) is redefined in this paper to include harmonics, oscillatory transients, voltage sags and swells. The new index is defined between the 0-1 range.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116248403","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 modern industrial infrastructure demands increasing amounts of affordable and reliable electricity. Solutions based on Flexible AC Transmission Systems (FACTS) can be used to control power flow on the grid. Shunt VARs compensators provide grid voltage support, while series VARs compensators are required to control active power flow. The Synchronous Static Series Compensator (SSSC) controls the active power flow by altering the impedance of the power lines or changing the angle of the voltage applied across the line. This paper presents a control algorithm for a SSSC which injects a voltage in series with the line in order to control the power flow. The amplitude and angle of the injected voltage is calculated as a function of the compensation rate and in order to control the DC bus voltage of the converter. A predictive synchronization algorithm is used to obtain the phase of the line current.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952547","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}

Both the drive and the active filter have been analyzed through an high frequency circuit model in order to identify the main propagation loops for CM disturbance. In particular the EMI emissions towards the grid are evaluated also in comparison with those generated in a configuration without the active filter. The accuracy of the model has been assessed by experimental measurements. Results show a reduction of CM EMI towards the grid in the lower frequency range of conducted emissions when the active filter is installed. This demonstrates that EMC requirements compliance of the drive can be achieved with a reduction in the size of the input EMI filter.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125114440","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}
