The influence of distorted angle information due to disturbances in the grid voltage, such as harmonics, unbalances, faults, etc., on the direct power control of the converter is taken into account through the use of an algorithm for voltage angle estimation. The control performance is compared in both cases, with and without angle estimation, as a mean of establishing an improving voltage ride-through capability of the converter in case of grid disturbances. The system has been simulated in MATLAB/Simulink and the simulation results have been validated with experimental results, obtained implementing the DPC and the angle estimation algorithm on a real-time DSP-based board (dSPACE ds1102), verifying the good performance of the proposed method","PeriodicalId":406067,"journal":{"name":"2006 IEEE/PES Transmission & Distribution Conference and Exposition: Latin America","volume":"451 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846957","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}

A double circuit transmission line is selected. Practical exposure scenarios which represent actual working conditions for live-line workers have been identified. The charge simulation method has been adopted to compute the external electric field around the selected 132 kV transmission line. A method based on Ampere law has been chosen to compute the external magnetic field around the transmission line. Both methods are numerically solved using the EPRFs EMF Workstation software. A comparison between the values of external electric and magnetic fields, with the allowable exposure limits set by the international standards has been conducted.
