Enhancing the Power Quality by Mitigating the Voltage in a Power System

The purpose of this survey was to improve power quality by using various custom power supply devices in the power distribution network to reduce the voltage drop / waves in the power system. In the past few decades, the development of compensators to improve power quality is of concern. Passive compensators such as shunt reactors and capacitors are uncontrolled devices and parameters can not be changed continuously. A new high speed compensator for modeling, simulation and analysis was developed.

Power quality is usually resolved based on several parameters. Common parameters such as flicker, current, harmonic, voltage drop, power, voltage, transient, etc. are processed by the power quality measuring device. These devices can handle a wide range of interference. Devices capable of handling multiple interference measurements are often the potential failure conditions and therefore are the main reasons used for power quality measurements. Because it is difficult to predict in advance which kind of interference will cause a potential obstacle, equipment with multiple interference detection functions is used.

If the voltage and frequency are within the normal tolerance range, the power quality is good. Poor power quality includes interference, voltage fluctuation, power surge and so on. An example of low power quality is surge due to lightning strikes during the storm. Another example is wiring failure in the panel, which can cause downstream distortion. Without protection of the power conditioner, poor power quality can cause various equipment problems such as failure, overheating, high maintenance cost, failure etc.

Power conditioners are used to maintain predictable voltages under varying loads. Using a power supply regulator is important to ensure excellent power supply quality. Power quality is the ability of the equipment to consume the energy provided by the grid. In other words, it is compatibility between the power outlet and the device. If the voltage and frequency are within the normal tolerance range, the power quality is good. Poor power quality includes interference, voltage fluctuation, power surge and so on. An example of low power quality is surge due to lightning strikes during the storm. Another example is wiring failure in the panel, which can cause downstream distortion.
