Differential Evolution (DE) algorithm is employed to find out optimal location and control of TCSC. This approach uses AC load flow equations with constraints on real and reactive power generations, transmission line flows, magnitude of bus voltages and TCSC settings. The input parameters are real and reactive power loads at all buses. The BPNN is trained through off-line simulation using DE algorithm and tested with new load patterns. The optimal feature set for training BPNN is obtained by a wrapper model of feature selection called Sequential Forward Selection (SFS). Simulations are performed on 39 bus New England test system. The performance of the proposed model is compared with unified BPNN trained with full feature set. The selection of optimal features with SFS has significantly reduced the training time of BPNN with minimal Mean Squared Error (MSE) for the evaluation of loadability limit of pool model with TCSC.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274111","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 function generator and digital multimeter instruments are available in all the labs, by integrating these devices a powerful yet cost effective instrumentation can be evolved. This paper describes such an instrument for capacitance measurement. MATLAB program interfaces the instruments through serial port and collects data, the applied and measured voltage at particular frequency, the results are analyzed to get corresponding Capacitance of the any capacitor under test.

With the normal pulse width modulation the converter is operated periodically and the EMI is measured. Using Random modulation the converter is forced to work chaotically and hence the EMI is measured. A comparative investigation on the use of Random modulation against the normal pulse width modulation is performed. FFT analysis is used for the comparison and it is found that the use of random modulation reduces EMI effectively. Simulated results validate the experimental results.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116075043","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}

Wind Energy Conversion System (WECS) based on constant speed squirrel cage induction generator is a popular system in India. Small signal stability analysis is very much essential to study the oscillations which normally exist in a power system and leads to unstable operation when small disturbances are applied. Basically, synchronous machine rotor is prone to weakly damped (low frequency) oscillations. But damper winding provides less damping for low frequency oscillations with small amplitude. It justifies the need for Power System Stabilizer (PSS) as a damper for oscillations. So, this work is intended to find the effect of wind energy conversion system on small signal stability conditions of conventional power system with synchronous generators with PSS. Eigen value analysis is conducted after developing a Differential-Algebraic model (DAE) in power balance form and tested on a modified 3 synchronous machine — 9 bus system with constant speed wind turbines.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124761774","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}

Software is developed in C language using IAR embedded work bench IDE for cold fire due to the inherent language flexibility, the extent of support and its potential for portability across a wide range of hardware.

Nowadays due to increased environmental awareness, generating utilities should optimize their emission in addition to the fuel cost. Recently researchers are developing different soft computing techniques to solve the combined economic and emission dispatch (CEED) problem. In this paper, Hybrid differential evolution Algorithm (HDEA) is developed to solve CEED problem considering security constraints as the traditional Differential evolution (DE) is suffers from local optima or stagnation problem. To evaluate the accuracy, convergence speed and applicability of the proposed method, it is implemented on the standard IEEE-30 bus system having six generating units to solve CEED problem and the results of CEED problem are compared with traditional PSO and DE. The tested results indicate that the proposed method is more efficient than the others in terms of fuel costs, emission, total losses and computational times.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120878344","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 hardware implementation has been carried out using operational amplifiers on a scaled down prototype to prove the effectiveness of the proposed topology.
