Published: December 2020

Abstract
A new design of immersion heater is proposed for common household use and is checked for stress induced due to heating and the corresponding factor of safety (FOS). Temperature distribution with time is obtained by building a finite element model of the simplified heater geometry (body) while considering conduction and convection due to buoyancy effect. For realistic results, a two-step analysis is done. Firstly, the temperature distribution with time, is calculated in Solidworks® Flow Simulation software by considering the conduction in heater body and convection in the surrounding water. Secondly, the calculated temperatures are exported into Solidworks structural simulation and thermal stresses are calculated. An effort is made to study the effect of purely thermal stresses on the heater body as it is heated under 3000 W power and visualize the flow trajectory of fluid particles as it is heated. The results are used to assess the stress, strain, and FOS of the design and to finalize its geometry. It is concluded in the study that buoyancy effects and flow trajectory of fluid particles is paramount in determining the thermal stresses in a heater design.

Published: December 2020

Abstract
Theoretical investigations have been carried out to find the advantages of using different nanofluids in Forced Circulation Loop (FCL) are presented in this paper. FCL finds its application in different heat transfer systems. Compared to the Natural Circulation Loop (NCL), FCL offers better heat transfer due to the higher heat transfer coefficient and more diffusion. Comparison among different chosen nanofluids has been made. Five different water based nanofluids (Al2O3, CuO, Cu, SiO2 and TiO2) have been chosen for the study. In order to calculate performance parameters, thermal conductivity and viscosity of nanofluids are measured and remaining properties are calculated based on the available correlations. From the present investigation it is found that using of nanofluids is beneficial in the way that it brings compactness to the heat transfer loops. Of course, there is trade-off between pressure drop and heat transfer characteristics and these aspects are also discussed.

Speed control of scim drive using fuzzy pi controller
Authors: Suresh J , Vamshidhar K , Rajababu D , Srinivas V. 
Published: December 2020

Abstract
Here we are using the scalar control approach for regulating the speed of SCIM(Squirrel Cage Induction motor), but in previous stage, a fixed frequency is set to the SCIM to maintain the constant speed. Here, the scalar ratio is sustain constant in order to get fixed twisting force throughout the entire operation. Since only input frequency and voltage are changed, this is known as “scalar control”. The SCIM implementing such a control are without any feedback approach. Hence, this regulating approach is low cost and maintenance free. This control is widely used because little information of motor is required. But at lower speeds, potential drop across stator impedance is more compared to air-gap voltage. So it has poor torque at low speeds. For that we will have to boost some voltage at low frequencies. We can go for Closed-Loop control if we want precise control. For voltage & frequency control of SCIM in proper ratio, VSI appropriate control method is necessary. The speed regulating of SCIM is more vital to achieve good performance and maximum twisting force. Here we implement a rule-based fuzzy logic controller supply to a scalar closed loop scalar SCIM regulating with slip regulation and its matlab results. The SCIM is modelled in terms of direct axis and quadrature axis windings.

Published: December 2020

Abstract
Advancement of power electronics and fabrication of self-commutated switching devices enhanced the prominence of multilevel inverters (MLI) for high power applications. The ability of MLI to be implemented with matured medium power electronic devices and less dc-link voltagesturnedtobeaviablealternativefor bulky transformer-based powerconverterforhigh-powermedium-voltageapplications. Though, these converters have wide market penetration for input transformer-less applications, their increase in switch count for higher-levels imposed size cost and complexity limitationsand, restricted them to lower levels.Need to reduce the device count requirement of the classical MLI configurations lead to the development of Reduced Device count (RDC) MLI configurations. Among the various RDC topologies reported, T-type has most appreciable reduced in switch count. This paper presents the implementation of the cascaded T-type RDC-MLI. Further the closed performance of the considered nine-level Cascaded T-type configuration is investigated by developing a shunt active power filter. The efficacy of the inverter for power quality enhancement is demonstrated in MATLAB/Simulinkenvironment.
Fault tolerant methods to reconfigure Multilevel level inverter for single and multiple open circuit switch faults
Authors: Vemuganti Hari Priya , Teja M.S. , Joshi Priyanka 
Published: December 2020

Abstract
Device ratings limitations of two-level inverters restricted their applications and increased the demand for Multilevel inverters (MLI) for various high-power medium-voltage applications. However, it is not just the low device ratings that have enhanced the impact of MLI, but there are other key factors such as less good harmonic profile (filter size) and fault tolerance. Fault tolerance of MLI sustaining the various internal and external faults contributes to inverter reliability and plays a vital role to enhancing practical feasibility. However, achieving fault tolerant operation of MLI by control its switching operation rather than involving any external/auxiliary hardware is the most economical solution. Thus, considering the most popular modular redundant classical MLI i.e., Cascaded H-Bridge, this paper presents the simplest fault tolerant strategies practically used to reconfigure CHB from open circuit (oc) switch fault(s). The fault tolerant operation (FTO) is demonstrated considering three-phase eleven-level CHB in MATLAB/Simulink environment.

ABSTRACT
Day to day the importance and usage of electric power is increasing, in order to reach this power demand, generation of power is being increased. But the transmission grid fails to meet the developments in generation, as construction of new transmission lines involve more time than building new generation facilities. So, updating or upgrading the existing facilities will be more beneficial than building new ones. This is achieved by providing proper reactive compensation. This main objective of the paper is placement of shunt capacitor for voltage profile improvement and reactive power compensation. The voltage stability index, called voltage collapse prediction index (VCPI), decides the shunt capacitor placement. This paper deals with placement of shunt capacitor banks to improve voltage at weakest buses. The shunt capacitor banks connected to the system to prevent the low voltages during the high loading conditions. The reactive compensation and reduction of losses and power transfer capability can be increased by placing of shunt capacitor. The proposed technique is validated with load flow analysis on IEEE 14 bus system carry out by Mi-power software. From the results obtained it is verified that the load flow analysis can be easily done with Mi-power which is a fast and robust tool with a powerful GUI to solve. Finally, the voltage profile improvement is verified with the placement of shunt capacitor.
