This study applies four different types of machine learning methods to model the power performance behaviour of a tubular solid oxide fuel cells (SOFC) under different operating conditions. The corresponding machine learning methods are: artificial neural network (ANN), fuzzy inference system (FIS), support vector machine (SVM), and genetic programming (GP). By using four types of inputs of the...

Installing a power system voltage regulator (PSVR) on the condenser can enhance dynamic control capability of local high-voltage bus voltage, but there are still few studies optimization PSVR parameters. The model is built to determine analytical expression between disturbance and change target, influence trend characteristics analyzed. Furthermore, in MATLAB/Simulink environment, PSVR-containi...

The main aim of this project is ,this topology enables UPQC to have a reduced dc-link voltage without compromising its compensation capability. Three-phase, four-wire unified Power Quality (UPQC) to improve power quality. The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor. The realization of shunt APF is carried out using a t...

A dual stator winding squirrel-cage induction motor (DSWIM) is a brushless single-frame induction motor that contains a stator with two isolated three-phase windings wound with dissimilar numbers of poles. Each stator winding is fed by an independent three-phase inverter. The appropriate efficiency of this motor is obtained when the ratio of two frequencies feeding the machine is equal to the r...

In this paper we systematically derive a linear model for an n bus m machine system with nonlinear voltage dependent loads at the network buses. The model is versatile and can be used to study diierent phenomena such as steady-state stability, voltage stability, etc. In addition to obtaining the system A matrix, we also obtain a transfer function between load voltages/angles and real/reactive p...

DC drives are still very important, especially for low voltages and low power (e.g. in cars and robots). In this paper a converter is analyzed, which makes it possible to control the voltage across the machine (and therefore the speed) from zero to more than two times the input voltage with a nonlinear, flat dependence at low duty cycles. This enables one to achieve high torque at low speeds wi...

This paper proposes a static synchronous series compensator based on H-bridge inverter modules. Dynamic response of proposed system was analyzed by EMTP simulation, assuming that it is inserted in the 154-kV transmission line of one-machine-infinite-bus power system. The proposed system consists of 6 H-bridge inverter modules per phase, which generate 13 pulses for each half period of power fre...
