In this method, the energy input to the boiler would be matched to the energy demand by the turbine generator. The existing control schemes have difficulty to cope up with inherent time delay, nonlinearity due to uncertainty of the combustion process and frequent load changes. This paper presents the design of fuzzy controllers for boiler to turbine coordination during normal load change operation and turbine to boiler coordination during sudden change in demand. The coordinated control will give set value for air/fuel controller for combustion process and throttle valve positioner to control the steam flow to the turbine inlet at all loads. A lab scale simulators for boiler, turbine, generator and high voltage sub station were fabricated along with two lab scale experimental set up for air/fuel control and throttle valve position control. Several tests were conducted for various load conditions. The feasibility is demonstrated through experiments using data collected from 210 MW thermal power plants. The advantages of the proposed system are highlighted.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125391524","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}

Power quality problems commonly faced are transients, sags, swells, surges, outages, harmonics, and impulses. Among these voltage sags and extended under voltages have the largest negative impact on industrial productivity, and could be the most important type of power quality variation for many industrial and commercial customers. Voltage sags is mainly due to the fault occurring in the transmission and distribution system, loads like welding and operation of building construction equipment, switching of the loaded feeders or equipments. Continuous voltage sags are also prevalent in many areas due to inadequate supply and demand situation. In this paper a switch mode AC voltage regulator is proposed to maintain constant voltage across a medium size domestic or commercial appliance. The proposed regulator has the capability of delivering sinusoidal input current with nearly unity power factor and the efficiency of the proposed regulator is high. This system incorporates high-speed insulated gate bipolar transistor switching technology. In this regulator the gate signal of the switching devices is generated by using a compact and commercially available IC chip SG1524B.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126348807","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}

This paper proposes a novel multilevel PWM strategy to have the advantages of low frequency switching and reduced total harmonic distortion (THD). The basic idea of the proposed area integration PWM (AIPWM) method is that the area of the required sinusoidal (fundamental) output and total area of all the pulses in every half cycle are same. The rationale for opting AIPWM is easy implementation of the control scheme in real-time digital platform. An additional crux objective of this paper is evolutionary computing based placement of the AIPWM pulses. The same is fulfilled by two soft computing techniques namely Evolutionary Programming (EP) and Genetic Algorithm (GA). A prototype seven-level cascaded inverter has been built and controlled with the novel PWM strategies.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128877494","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}

Several modulation methods have been applied to multilevel Inverters. The modulation methods with higher switching frequency reduce filter size but increases switching losses. The Step modulation method operates with low switching frequency has less switching losses but it requires large filter size. To reduce the filter size the number of levels of the inverter is increased but it increases the cost of the system. This paper presents a novel modulation method where additional notches are introduced in the multi-level output voltage. These notches eliminate harmonics at the low order/frequency and shifts it a higher order/frequency and hence the filter size is reduced without increasing the switching losses and cost of the system. The proposed modulation method is verified through simulation and such results are also validated practically using a five-level Diode-clamped inverter prototype.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126740016","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}
