Photovoltaic (PV) water pumping system has been becoming increasingly important in remote, isolated, and non-electrified population, where either accessibility to the grid is difficult to establish or implementation cost is indeed very high. In such location, PV water pumping application is...

The paper illustrates some aspects of energy conversion processes during underground electric train operation. Energy conversion processes are explained using exergy, in order to support transport system sustainability. Loss of exergy reflects a loss of potential of energy to do work. Following...

The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid....

Harmonics estimation methods are analyzed in presence of different power quality problems, namely voltage sags, voltage unbalance, voltage distortion and variations of power supply frequency. The harmonics detection algorithms are based on the instantaneous reactive power (IRP) theory, the...

Voltage unbalance (VU) in residential distribution networks (RDNs) is mainly caused by load unbalance in three phases, resulting from network configuration and load-variations. The increasing penetration of distributed generation devices, such as small wind turbines (SWTs), and their uneven...

Обсуждается задача синтеза системы управления для двигателя постоянного тока независимого возбуждения с многоуровневым преобразователем напряжения....

Paddy is the most important agricultural crop product in Bangladesh since it is widely used in daily life as a main meal intake. Currently, traditional manual harvesting process is widely used to harvest paddy grains in Bangladesh. However, manual harvesting is laborious, time-consuming, and...

The detailed simulation method for brush motor is based on the matrix resolution of the differential electrical equations of the armature coils with a collector model. This method is well adapted to compare different configurations of armature winding that can be easily implemented with two...

This article presents a method for fault detection and diagnosis of stator inter-turn short circuit in three phase induction machines. The technique is based on modelling the motor in the dq frame for both health and fault cases to facilitate recognition of motor current. Using an Adaptive...

This article describes how a field oriented control can provide the same performance as it is achieved by a DC motor. However, this technique requires a mechanic sensor and is very sensitive to the variation of motor parameters which results in an undesirable coupling between the flux and the...
