Alternating current is in by pure resistance, and electric energy has all changed into heat energy, and in by pure capacitive or pure inductive load, does not do work. It is without consuming electric energy, is reactive power. Certain actual loading, can not be purely capacitive load or pure inductive load, it is typically all Combination load, such electric current is by them, just having part electric energy not do work, be exactly reactive power, power factor now is less than 1, in order to improve the utilization rate of electric energy, reactive-load compensation will be carried out.
This power can cause voltage landing (during inductive reactance) or voltage to raise (during condensance) and joule (resistance heating) loss in electrical network, but can not make effective merit. So that reactive power is compensated. Reasonable disposition reactive-load compensation (where include, with many Large Copacity and adopt which kind of pattern) is an important content in Power System Planning and design work. Being in operation, reasonable employment reactive compensation capacity, the flowing of control reactive power is one of groundwork of electric power system dispatching.
The effect of reactive power compensation cabinet is the electric substation in power system or directly installs reactive power power supply in electric power users electric substation, to change the flowing of reactive power in power system, thus improving the voltage levvl of power system, reducing via net loss and improve the dynamic property of power system, this technical measures are called reactive power compensation.
