This paper deals with the problem of harmonic mitigation solutions in a Romanian traction
substation which supplies a railway electric transportation line. The power line …

The railways are used to transport people, but also for the industry. In this article we present
a simulation of real DC traction power supply that intended to transport the natural resources …

This paper presents a model predictive control for shunt active power filters in synchronous
reference frame using space vector pulse-width modulation (SVPWM). The three phase load …

Electricity has become an important concern in today's society. This is due to the fact that the
electric grid now has a greater number of non-linear components. The AC-powered …

Experimental measurements were made at the low voltage electrical power station of a large
hospital, in a point of common coupling. The measurements were made with a power quality …

The paper presents a device with microcontroller for measuring the power factor used for
single-phase low voltage electrical consumers. Voltage and current are measured, and the …

The article presents an analysis of asymmetric currents protections for general-purpose
three-phase low voltage induction motors. Dedicated electronic protection is provided to …

Low-voltage three-phase induction motors are most often used in industrial electric drives.
Electric motors must be protected by electric and/or electronic devices against: short-circuit …

This paper presents a study about power quality problems generated by line frequency
coreless induction furnaces. We analyzed a furnace with 12.5 t capacity of cast-iron. The …

In this article are presented the basic principles of the numerical protections used for
protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a …
