We conducted energy and exergy analyses of an adsorption chiller to investigate the effect recooling-water temperatures on cooling capacity Coefficient Performance (COP) with variable cycle modes. investigated both temperature dead state destruction in components. Our results show that there is optimum reheat mode for each range. For basic single stage cycle, mainly accrued desorber (49%), foll...

nowadays, energy plays an important role in the economic and community development of country. consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. among the different power generation technologies, steam power plants make a significant contribution to power generation in iran, with a share of 47 % of electricity g...

The present paper describes the energy and exergy analysis of a reheat regenerative vapor power cycle. The plant consists of one boiler feed pump, one supercritical boiler, two steam turbines with a reheater in between, two feed water heaters (one open and one closed) and a condenser. The energy and exergy balance study has been carried-out for each component of the plant. Energy efficiency, ex...

Robust control has emerged as a new field of control engineering research that primarily deals with obtaining system robustness in presences of uncertainties. In this paper, a graphical design method for obtaining the entire range of PI controller gains that robustly stabilize a non reheat AGC plant in presence of additive uncertainty is discussed. This design method mainly depends on the frequ...

Abundance of stable charged massive particles (CHAMPs) is severely constrained by their searches inside sea water. We examine whether inflation with low reheat temperature can sufficiently dilute the abundance to evade this severe bound on CHAMPs, by taking into account their production and annihilation in a plasma during reheating phase. We argue that the abundance of the CHAMPs with mass less...

This paper presents a theoretical investigation of a combined Power and Cooling Cycle that employs an Ammonia-Water mixture. The cycle combines a Rankine and an absorption refrigeration cycle. The Goswami cycle can be used in a wide range of applications including recovering waste heat as a bottoming cycle or generating power from non-conventional sources like solar radiation or geothermal ener...

This paper proposes a design of Artificial Bee Colony (ABC) algorithm based Proportional plus Integral controller using Area Requirement (AR) Criterion for the Load Frequency Control of a two area multi unit interconnected thermal reheat power system without and with Gas Turbine unit. The system was simulated and the output responses of the frequency deviations, tie-line power deviation and con...

Abstract: In the present work, we focus on the study of dynamic behavior of an interconnected two-area power system and a scheme for improvement of response for the same. Here, two-area system with one non-reheat thermal units & one reheat thermal units is considered. The frequency and tie-line power deviation of two units are studied using MATLAB-SIMULINK in continuous time domain and also in ...
