Reactive power in power distribution system?




(1) power supply capacity increases, increased investment (in the power grid load unchanged, reactive power increases, will increase the power supply capacity)
(2) affect the quality of power supply, power grid fluctuations, voltage quality decline, the use of electrical equipment life reduction. It can be concluded that the voltage drop at the first end is mainly determined by the number of reactive power transmitted on the line
(3) due to the increase of reactive power, the active power loss and power loss are also increased. In the distribution system, the power loss caused by reactive power consumption is greater than the active power loss.
