Electrical Power Transmission: Voltage Control

Which statement is False ?

• Reactive power causes only reactive power loss in the transmission systems.

• Reactive power flow in transmission line is depends on the voltage level on two sides of the line.

• Transfer of reactive power is the main reason for voltage drop.

• Reactive power increase the load current of the line.

Which one isn't among the requirements for keeping the voltage level in the allowable range:

• Enough compensation capacity.

• Control of compensation capacity

• Enough active power capacity in power plants.

• Transfer of reactive power tried to be avoided

Which one is not a reactive power consumer?

• Reactor

• Transformer

• Underexcited generator

• Overexcited synchronous motor
