The effects are irreversible. The conventional optimization techniques have convergence problems for large system and heuristic methods reported so far are not holistic in nature. This paper proposes a two level approach. At first level, the usual static solution using linear approach is proposed. The objective is to minimize the cost along with overloads. The isolated nodes are handled by ZBUS formulation as described. The genetic algorithm (GA) is used as a heuristic approach to arrive at results. The plans are shortlisted with no overloads and least cost. The performance is tested for high rank contingencies and appropriate system strengthening is suggested. At second level, further strengthening of the network on short term basis is done with due consideration to reactive power balance in the grid. The reactive power support has to be incorporated since the AC model with reactive power limits can impose convergence problems. To overcome this, reactive power compensation (RPC) enhanced FDLF module with integrated reactive power planning based on set of heuristics is implemented. The TEP plans need to be evaluated for reactive power balance. This is accomplished by evaluating voltage stability margin index (VSMI). It identifies weaker lines prone to reactive power imbalance. The TEP plan reinforces grid to improve the weaker section. The proposed methodology is applied to IEEE 46-bus test system and results are discussed.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130903609","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}

SVPWM DTC technique is helpful in solving the basic issues of torque ripple and variable switching frequency present in the conventional DTC. Three PI controllers one each for speed, torque and flux feedback loops is used in SVPWM DTC based IM drive. The major issue related with SVPWM DTC based IM drive is the proper setting of the parameters in speed, torque and flux control loops. As they are inter-dependent in nature, their parameter setting is a tricky issue. No proven technique is available to address this issue and so it can be observed that because of the lack of proper parameter settings, the induction motor drive performance is affected in terms of higher torque ripple. In present work an attempt is made to address this problem using the frequency analysis technique. Simulation results for the SVPWM DTC based on this method and conventional DTC are compared. Hardware results validate the simulation result and hence proposed technique.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"30 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114113779","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 main thrust in wind energy conversion system (WECS) is to maintain a constant voltage at the output in spite of variation in wind velocity. The Z-source inverter has been identified to exhibit in steady-state, both voltage buck-and boost-capabilities. It employs a unique impedance network included between the dc power source and converter circuit. The power conversion efficiency of Z-source inverter is appreciably improved because of the traditional three-stage conversion system, consist of rectifier, boost chopper and inverter, replaced by a two stage conversion systems comprising of rectifier and Z-source inverter. All the traditional pulse width-modulation (PWM) schemes can be used to control the Z-source inverter. When the dc voltage is high enough to generate the desired ac output voltage, normal PWM is used. While the dc voltage is not enough to directly generate a desired output voltage, a modified PWM with shoot-through zero states is employed to boost the voltage. The proposed Z-source inverter with PMG and wind turbine is modeled and simulated using MATLAB/SIMULINK.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"67 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125932730","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}
