The role of the inactive power compensation device in the electric power supply system is to enhance the power factor of the grid, reduce the loss of the power supply transformer and transmission line, enhance the power supply efficiency as well as improve the power supply environment. Therefore, the inactive power compensation device plays a very important role in the electric power supply system. To reasonably select the compensation device can reduce the line loss to the greatest extent, making the grid quality to be enhanced. In contrast, in case of improper selection or use, the factors such as voltage fluctuation and increased harmonic wave etc. of the power supply system will be caused.
The equipment such as AC asynchronous motor and induction cooker etc. which is widely applied to the industrial production is inductive load, which makes the voltage applied on it exceed one angle than the current during the energy conversion process. The cosine of this angle is called power factor. When the power factor, i.e. inactive power is great, the disadvantages are as follows:
lIncrease the line current to make the line loss to be increased to waste electric energy;lBecause the line current is increased, if the transmission line is long, the voltage reduction on the line will be greater. The too low voltage will impact the normal use of the equipment;
Capacitance compensationlIncrease the voltage of the bus and feeder line.
lEnhance the power factor of the power consumption of the unit.
lReduce the total current of the incoming lines of the power station.
lReduce the transmission of the inactive electric energy of the distribution lines and reduce the electric energy loss on the distribution lines.
lIncrease the loading capacity of the transformer.
lExploit the equipment potential, enhance the equipment output and fully enhance the utilization rate of the equipment.
