Power factor improvement using active filter for unbalanced three-phase non-linear loads
In this paper, a modified shunt active filter is used under unbalanced three-wire supply voltages with non-linear loads. The main objective of the proposed shunt active filter is to control the three-phase supply currents both in its waveform, magnitude and phase to follow three-phase reference signals. The reference signals are derived from one of the phase voltages. When this is achieved, ...

Power Factor correction capacitors for utilising power consumption in industrial plants
Installation of capacitor banks proved to be cost effective approach to correct power factor in industrial plants. Optimum capacitance value that contributes to the maximum PF improvement varies from one system to another. Such value depends on the existing electrical system within the industrial plant. This paper provides industrial plants operators an optimisation model to correct and improve ...

MATLAB-based modelling of Distribution STATCOM applied to isolated power system
This paper presents the modelling of Distribution Static Compensator (D-STATCOM) used in isolated power systems. The model of D-STATCOM is developed using Power System Block-set (PSB) and Simulink toolboxes of standard MATLAB software. Two proportional integral PI controllers are used to control DC bus voltage and AC bus voltage regulation at the point of common coupling. Results are presented ...

The Benefits of Using a Frequency Drive Pump for Energy Efficiency
Pumps are very important in many different settings, from factories and businesses to homes. They are used to move water and other liquids from one place to another. However, traditional pumps that run at a fixed speed can save energy and money. A better option is to use a frequency drive pump, which is also called a variable frequency drive pump or variable frequency drive well pump. These pumps ...

Three–phase modular single stage full–bridge converter for switched mode power supplies
In this paper, the modular development of a three–phase single stage ac–dc power converter based on single–phase ac–dc isolated full–bridge converter for telecom power supply applications is presented. Three single–phase converter modules are series connected to form a three–phase converter system to achieve balanced three–phase currents. This paper analyses the operation of a modular converter ...

DSTATCOM for power quality improvement in a four-wire electric distribution system
This paper deals with the simulation of a Distribution Static Compensator (DSTATCOM) for power quality improvement in a four-wire electric distribution system. A three-phase Insulated Gate Bipolar Transistor (IGBT)-based Current-Controlled Voltage Source Inverter (CC-VSI) with a DC bus capacitor is used as a DSTATCOM. The DSTATCOM improves the supply power factor, eliminates harmonics, provides ...

Meaning and role of reactive power quadrants in electric meter
The reactive power quadrants in electric meter refer to dividing a plane coordinate system into four regions, with the horizontal axis representing reactive power and the vertical axis representing active power. Each region represents a different combination of reactive power and active power states. These four regions are known as quadrants I, II, III, and IV, each with its own meaning and ...
