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 ...
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. ...
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. ...
In this paper, a novel phase locked loop less control algorithm for harmonic and reactive power compensation with power factor improvement using three-phase shunt active power filter under non-ideal mains voltage conditions is presented. ...
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. ...
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 ...
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. ...
When this is achieved, ideally the supply current will then be always sinusoidal, with robust control over its magnitude and phase, irrespective of the harmonics and unbalance of the load demand or the supply voltage system. This confirms nearly unity power factor on supply side and reactive compensation by the active filter in static-compensator mode. ...
