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.
Which is are the advantages of FACTS controllers Mcq?
The objectives of FACTS controllers in the power system network. … Better the control of power flow (Real and Reactive) in transmission lines.
Which of the following is the 2nd generation FACTS device?
Development of FACTS Controllers
The second generation (e.g., STATCOM, SSSC, UPFC, IPFC, etc) are converter-based devices and use switching static converters as fast controllable voltage and current sources.
Which are the shunt compensation devices?
The static synchronous series compensator (SSSC) and thyristor-controlled series capacitor (TCSC) are some of the FACTS control devices which provide series compensation to reactance of the lines to which they are connected, while the static synchronous compensator (STATCOM) and static VAR compensator (SVC) (where VAR …
What is the purpose of series compensation?
Series compensation is a well established technology that is primarily used to reduce transfer reactances, most notably in bulk transmission corridors. The result is a significant increase in power transfer capacity and improvement of voltage and angular stability in transmission systems.
What is the basic principle of series compensation?
Series capacitive compensation method is very well known and it has been widely applied on transmission grids; the basic principle is capacitive compensation of portion of the inductive reactance of the electrical transmission, which will result in increased power transfer capability of the compensated transmissible …
What is SVC Mcq?
Explanation: The full form of SVC is Static Var Compensator. It is a FACTS controller used for reactive power compensation. … Explanation: SVC stands for static var compensator. It is the FACTS controller used for reducing the harmonics from the system. It is used for reactive power compensation.
What is possible with the help of a reactive compensator Mcq?
With the help of a reactive compensator it is possible to have. constant voltage operation only. … either constant voltage or unity p.f.
What are the objectives of facts devices?
The main operational objective of both FACTS devices is to increase power transmission capability by voltage control at the point of connection of the power network. So for better utilization of available or present power system, flexible AC transmission systems (FACTS) controllers have been implemented.
Which one is combined shunt and series connected controller?
Thyristor Switched Capacitor (TSC)
It consists of a shunt connected capacitor which is connected in series with bidirectional thyristor switches. The impedance or reactance of this device is varied in a stepwise manner by controlling the thyristors either in a zero or full conduction operation.
What is electrical SSSC?
The static synchronous series compensator (SSSC) is a power quality FACTS device that employs a VSC connected in series to a transmission line through a transformer or multilevel inverters.
Which is the main types of distribution system in India?
There are three basic types of distribution system designs: Radial, Loop, or Network.
