Voltage Control in a Power System with the Help of Reactive Power Control

Nitriding is a case hardening thermo-chemical process used in many applications today. Nowadays, the improvement of ferrous materials performance is a problem of high interest. One of well known wear and corrosion properties improving technique is plasma nitriding, in which elemental nitrogen is introduced to the surface of a metal part for subsequent diffusion into the material. As a result, a compound, “white” layer and a diffusion zone are formed at the surface. A literature research was done in order to study the nitriding mechanism and different nitriding methods used in industry. To deliver the active power (watt) through the transmission lines, the reactive power (Var) is necessary to maintain the voltage. In case of voltage sag reactive power support, voltage can be restored. Also, to regulate the power factor of the system and maintain voltage stability, we need to replenish the reactive power. Due to the decrease in the load voltage and the change in the load, the change in the voltage level in the system causes the increase in the demand for reactive power. If this demand is not completed by the electricity system, then the voltage decreases again. Due to the voltage of these components, there is a rapid decrease in the voltage at a particular location. The lack of this voltage of the special place will have an effect on the surrounding areas, which can be due to further voltage collapse. This project describes a model in which a coordinated and interconnected set was placed in the form of controlled shunt and series elements. For each device, functional features, specific settings and controls, and simulation examples are presented. The model is capable of representing almost any facts device for power-flow and all type of simulation. Citation: Gajjar Anand R, RK University.
