Taschenbuch. Condición: Neu. Neuware -The increasing demand for electricity and the emergence of smart grids have presented new opportunities for home energy management (HEM) systems for the purpose of reducing energy usage. With the deployment of smart meters, it is possible to perform load control using HEM system with DR enabled appliances. The objective is to develop an intelligent HEM system with DR enabled appliances considering, home occupancy, user comfort, and electricity price. Simulation models of four home appliances, namely, air conditioner, water heater, washing machine, and refrigerator were developed based on mathematical and measurement empirical models using the Matlab/Simulink software. In addition, hardware prototype smart sockets were designed and built to link the home appliances to the HEM controller. The intelligent HEM system can make accurate decision in scheduling and shifting the domestic load operation at the peak period by scheduling the electrical appliances at a specific time without affecting the comfort of customers. 172 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Shaft voltage has become a serious problem in large power plants. This book assigns the potential sources of shaft voltage and its effects on bearings. The shaft voltages and bearing currents are due to the common mode voltage component of the output voltage from the static excitation system. The main objective of this book is to develop a gas turbine generator excitation-shaft-to-bearing model and simulate the model to investigate the shaft voltage and bearing current occurrence in a power station. To address the shaft voltage by using grounding brushes is proposed, the simulation of the developed model is implemented by the Matlab. The values of shaft voltages and bearing current on the exciter end and the turbine end are investigated based on the data that had been obtained from Sultan Power Station manual. The results of shaft voltages and bearing current with and without the shaft to ground brushes connected at the exciter end and turbine end are analysed. In this book, optimization solver is also employed to determine the optimal values of capacitor and resistor to model the grounding brushes used to eliminate shaft voltage at exciter end and turbine end of the generator. 108 pp. Englisch.
