This paper presents the simulation modelling of thermodynamic model of 120MW coal fired power plant of that use as a thermal power generation to calculate the electrical output of a coal-fired power plant. Initially, a detailed model of a coal-fired power plant is designed to calculate energy and efficiency of the plant. This model predicts useful heat input and thermal losses that occur in the power plant. Thermodynamic models are working on the first law of thermodynamics using balance equations for each component. The power plant making some assumption performance is evaluated in design conditions. Every component is modelled as a single control volume at steady-state conditions. The pressure drops on the lines are not considered and gland steam is neglected. Trivial changes in fluid state between the outlet of one component and the inlet of the next are assumed and also the potential energy and the kinetic energy are neglected.
Demand of the energy is gradually increasing and as the conventional sources are about to be emptied, new types of energy sources must be create in order to meet the future demands. One of such sources is the photovoltaic cell, which converts sunlight to electrical current, without any mechanical or thermal hardware. This paper represents the design of techno-economical feasible inverter of 1Kw capacity for the use of domestic solar panel. The whole system consists of a single solar panel of 17V-10W, Charge Controller of 600mA-15V and DC to AC inverter. The DC power generated by solar panel is directly fed to the load by converting it into AC power using Inverter. The invert designed is a single phase matrix converter which performs a function such as frequency changer, rectifier, inverter, chopper etc. IGBTs in inverter circuit are switched by pulse width modulation obtained from comparator circuit. Batteries of suitable range are used to store the power. The simulation of inverter is carried out in MATLAB / SIMULINK and hardware design is obtained using readily available IC's and other components.
This paper presents an efficient mathematical and simulation model for a solar photovoltaic system. This is an analysis on the characteristics of photovoltaic (PV) Cell under various weather conditions. Considerably, the PV cells are nonlinear in nature, whose characteristics and the maximum power point varies with irradiance and temperature. It focuses on the effect of variation in series and shunt resistances. The model is proposed to study the expected environmental issues on the solar power generation. By the help of this model, a study of large PV system or solar energy system can be done easily. This model elaborates various effects of parameter variation on the P-V and I-V characteristics of the PV module. This model was developed with the help of Simulink software and can be utilised for various study and research purposes.
These days, the induction motor driven by inverter, drives are being popular and used in the industries for variable speed applications with very competitive pricing. In this paper, a new dynamic pulse width modulated inverter fed squirrel cage induction motor simulation model is used for the stator inter-turn winding fault detection purpose. Through the proposed model, the transient behavior of the induction motor has been analyzed for healthy as well as for stator interturn faulty conditions by time domain approach. Therefore, early, stator inter-turn fault diagnosis is possible and may avoid the motor to reach in the catastrophic conditions. Therefore, may save large revenues for industries.
Common Cause Failures (CCF) would indicate the failures of multiple components in a system due to some cause. In this paper, an attempt has been made to analyze the Limiting State Probabilities (LSP) of states for small repairable systems in which, the components are prone for failures due to CCF. For large systems, the same can also be used, as failure modes represent cut sets of the system and it is known that cut sets of order more than three can be ignored as they don't contribute much to predict the indices for approximate system reliability analysis. Analysis of repairable components with CCF is presented with a case study.
