What are the objective of line compensation?
The purpose of series compensation is to cancel part of the series inductive reactance of the line using series capacitors. This helps in (i) increase of maximum power transfer (ii) reduction in power angle for a given amount of power transfer (iii) increased loading.
What are the objectives of reactive power compensation?
The main purpose is to decrease the voltage fluctuation at a given terminal of transmission line. Therefore the VAR compensation improves the stability of ac system by increasing the maximum active power that can be transmitted.
What is the function of shunt controller?
Static Var Compensator
It is a shunt type controller which controls the power flow in transmission system and improves the transient stability of power grids. This controller regulates the voltage at its terminals by controlling the amount of reactive power injected into or absorbed from the power system.
What is shunt and series compensation?
In series compensation, the FACTS is connected in series with the power system. It works as a controllable voltage source. … To compensate, a shunt capacitor is connected which draws current leading the source voltage. The net result is improvement in power factor.
What are the three main objectives of the load compensation?
The main objectives in load compensation are: Improved voltage profile • Power factor improvement • Balanced load.
What are the two aspects of reactive power compensation?
Reactive power compensation is defined as the management of reactive power flow to improve the performance of the power system. It is related to both the system and customers. Generally we can look to the reactive power compensation from two aspects: load compensation and voltage support.
What is the importance of reactive power compensation give three points?
Voltage control in an electrical power system is important for proper operation for electrical power equipment to prevent damage such as overheating of generators and motors, to reduce transmission losses and to maintain the ability of the system to withstand and prevent voltage collapse.
What is series compensation?
Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. It improves the power transfer capability of the line.
What are the different types of compensation used in power system?
Reactive power compensation in a power system is of two types—shunt and series. Shunt compensation can be installed near the load, in a distribution substation, along the distribution feeder, or in a transmission substation. Each application has different purposes.
What are the benefits of facts?
FACTS enhance the overall grid capacity and performance. They also increase the reliability and efficiency of your power system. By mitigating power oscillations, FACTS are able to offer you greater control over your energy.
