Abstract: This work presents the development process of Refrigerator test ring and then carry- out the per- formance analysis of domestic refrigerator. The experiment platform which is called refrigerator test ring will be developed from refrigerator model. Performance  of  refrigerator  also  depends  on  inlet  and  outlet  condition  of  each components. So in this research work refrigerator test ring will be developed and obtain performance of domestic refrigerator in term of Refrigeration Capacity, Compressor Work and Coefficient of Performance (COP) by determining two important parameter during operating condition which are temperature and pressure. So carry out this project I use different alternative refrigerant and find the data and compare the data to each other and then find the alternate of R 134a.

Keywords: refrigerator, experiment platform, Refrigeration Capacity, Compressor Work, temperature, pressure.

Abstract: The concept of Flexible Alternating Current Transmission system (FACTS) brought radical changes in the power system operation and control. A new technique using FACTS devices linked to the improvements in a semiconductor technology opens new opportunities for controlling the power and enhancing usable capacity of the existing transmission lines. The Unified Power Flow Controller (UPFC) is the most versatile and complex power electronic equipment that has emerged for the control and optimization of power flow in electrical power transmission system. This paper presents real power, reactive power and power factor control through a transmission line by placing UPFC at the different lengths of transmission lines. When no UPFC is installed, real and reactive power losses in the transmission line can’t be controlled. This research deals with simulation of transmission line using UPFC to improve the real power, reactive power and power flow control through a transmission line. In this research paper a Simulink Model is considered with UPFC model to evaluate the performance of a single and double transmission line of the transmission systems.

Abstract: Performance of Installed TCSC Projects”. This paper presents brief investigations on performance of Installed Thyristor Controlled Series Compensator (TCSC) projects world around. The main and basic objective of TCSC’s in power system is to enhance power flow and improve system stability. The deployment of TCSC in transmission line also improves SSR mitigation, Power Oscillation Damping (POD) and Transient Stability (TS). The paper intends to discuss some important TCSC projects installed world around and highlights the benefits derived in terms of enhancing power networks. In the case of a TCSC such a scheme should consider the different control levels acting on the same control variable, which in this paper is assumed to be the fundamental frequency equivalent impedance, as this is the control variable most commonly studied in the literature. In this kind of hierarchical control design is difficult connections between the different control levels may be expected when not properly coordinated. The main aim is to analyze the design of a hierarchical TCSC controller for stability enhancement, taking into account interactions among the different control levels.
