This bidirectional convereter can acts as an ac to dc boost rectifier with near unity power factor at the grid side along with regulated and ripple free dc voltage at the output. This paper presents voltage oriented control of the three phase PWM rectifier with Bus Clamped Space Vector Pulse Width Modulation(BCSVPWM) to reduce the switching loss and to improve the performance. The performance of the rectifier with BCSVPWM has been compared with the conventional Sine PWM(SPWM) and the regular Space Vector PWM (RSVPWM)techniques. The input current harmonics, Switching loss, Output dc voltage range and the dynamic performance are analysed with MATLAB/Simulink and better results are obtained with the propoded method.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121206879","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}

Voltage instability may be due to a disturbance occurring at some location in the power system. The increase in active and reactive power loss along the heavily loaded transmission network is another undesirable effect of the same. In this paper a solution to this problem is put forward by using series connected flexible AC transmission system (FACTS) controllers, namely thyristor controlled series capacitor(TCSC) and static synchronous series compensator(SSSC). The main objective of this paper is to provide adequate compensation to reduce system losses and to improve the voltage profile of the system. The optimal location for installation of the FACTS device is found out using the line stability index Lmn and validated using power flow studies. The performance of the controllers are compared to find out the best one in terms of voltage stability enhancement and loss reduction. The test has been conducted in MATLAB/PSAT environment and the test system considered is the WSCC 9 bus system.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121649098","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}

Various power conditioning devices such as FACTS devices are developed for power quality improvement. Among them Shunt Active Power Filter (SAPF) is used for harmonic current compensation. SAPF supplies the reactive power required by the nonlinear load and maintains the power quality at source side. Performance of SAPF is at its best during ideal grid voltages. When the grid voltage is distorted with harmonics the THD reduction using SAPF is poor. In this paper performance of a p-q theory based SAPF is analyzed. Then a new improved control with p-q theory is used to improve the performance of SAPF during non ideal grid voltage conditions and the results are compared.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125661911","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}

PMSM are widely used in industrial applications such as robotic manipulators and machine tools due to its high efficiency, high torque to weight ratio and smaller size. One of the efficient control strategies of PMSM is based on Vector Control or Field Oriented Control. Sliding mode control (SMC) is a very popular technique to deal with uncertainties. System dynamics in such cases can be improved by combining the intelligence of fuzzy logic with the sliding mode control technique. Performance comparison of a Fuzzy sliding mode controller with Triangular and Gaussian membership functions and also with conventional PI controller and adaptive fuzzy PI controller for the vector control of a PM Synchronous Motor is carried out in this paper. Results of this study show that the system performance is improved when Fuzzy SMC with triangular membership function is used for the speed control of PMSM.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117119787","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 cascode converter utilizes two buck-boost converters (lower and upper semi-stage converters); they are integrated with a single active switch. The input voltage of lower semi-stage is from the dc source. The input voltage of upper semi-stage is from the dc source and the output voltage of the lower semi-stage by series. Thus the overall output voltage of the converter is the sum of output voltages of the two semi-stages by cascode. Hence a dc-dc converter with high voltage gain is achieved without extremely high duty ratio. Then the performance of this cascode converter is investigated with the utilization of maximum power point tracking (MPPT). So this paper also deals with mathematical modeling and simulation of a solar photovoltaic module. The PV cell exhibits non-linear voltage-current characteristics or non-linear power curve, so its maximum power point varies with weather conditions such as solar insolation and ambient temperature. It is observed that there is a unique maximum power point for a PV cell at a particular weather condition. This maximum power point can be tracked efficiently based on incremental conductance method. The system includes a dc-dc cascode converter, PV module and a MPPT controller. The complete system is analyzed using MATLAB/Simulink.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125872317","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}

In wind power market Double Fed Induction Generator, is popular wind turbine system due to its reduced mechanical stress and high efficiency compared to others. But it is very sensitive to grid disturbances and can damage the power electronic converters connected to the machine due to over voltage and over current due to fault ride through. Therefore, protection elements which disconnect the machine from grid during fault are essential, crowbar is used as a basic protection. But, in such cases, the reliability of the system gets affected which is not acceptable due to the high penetration of wind energy into the grid. Fault ride through (FRT) is a mechanism by which the wind turbine can be connected to the system during the voltage dip. Many hardware and software control methods are implemented for the uninterruptible operation of DFIG during the grid voltage fluctuations.
