Induction machines are mostly used as generators in wind power based generations. Since induction machines have a stability problem as they draw very large reactive currents during fault condition, reactive power compensation can be provided to improve stability. This paper deals with the Impact of STATCOM on the Wind Farm performance. The essential feature of the STATCOM is that it has the ability to absorb or inject fastly the reactive power with power grid entirely by means of electronic processing of the voltage and current waveforms in a voltage source converter (VSC). This function is identical to the synchronous condenser with rotating mass. In the present work transient stability improvement and critical clearing time(CCT) analysis using STATCOM under faults is proposed. Improvement of transient stability with and without STATCOM and reactive power injection by STATCOM is studied. Simulation results are given, commented and discussed. The test results prove the effectiveness of the proposed STATCOM controller in terms of fast damping the power system oscillations and restoring the power system stability.","PeriodicalId":105826,"journal":{"name":"2014 International Conference on Smart Electric Grid (ISEG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129245885","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}

To enhance the performance of the conventional controller (Hysteresis controller) and to take advantage of intelligent controllers, a back propagation algorithm based feed forward-type ANN technique is implemented in shunt active power filter for producing the controlled pulses required for IGBT inverter. The proposed approach mainly work on the principle of energy stored by capacitor to maintain the DC link voltage of a shunt connected filter and thus reduces the transient response time when there is abrupt variation in the load. The complete power system set model of the proposed filter technique has been developed in MATLAB. The control algorithm developed is very simple. Simulations are carried out for the proposed scheme by using MATLAB, it is noticed that the %THD is reduced to 2.27% from 29.71% by ANN controlled filter. The simulated experimental results also show that the novel control method is not only easy to be computed and implemented, but also very successful in reducing harmonics.","PeriodicalId":105826,"journal":{"name":"2014 International Conference on Smart Electric Grid (ISEG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133159498","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}
