The system of a novel full - automatic power factor compensator by MCS - 80C196KC can compensate each phase load respectively to increase the power factor and apply to the power users of unsymmetrical 3 - phase loads especially.
According to the changes of reactive power and voltage of the power system in working face, the device can automatically switch the capacitor bank in order to increase the power factor, improve power supply and save energy.
The article analyses how to increase the power factor, how to decrease the power loss, how to increase the voltage quality and so on,and also explains the importance of the distribution network's reactive compensation.
By analyzing the action of reactive power compensation on the electric power system, 4 kinds of reactive power compensation projects of the distribution system are technically compared and the determination of the compensation capacity is discussed. The reasonably choosing the way and the capacity of reactive power compensation can increase the power factor, decrease the energy loss and improve the quality of electric pressure, thus reaching the aim of conserving power and improving power guality.
With AC filter installation being reasonably selected, high - order harmonic voltage may be very well eliminated to reduce its influence on power network, and to increase power factor and decrease harmonic loss.
To suppress harmonic,increase power factor and improve power quality,a suitable scheme for harmonic control and reactive power compensation was formulated according to field-measured datas,collected using Power SATELITE.
This paper presents the cross-interference problem caused by the mutual effect between two fluorescent tubes, and the influence of harmonic currents on improvement of power factor, as well as the importance of using restraint of harmonic currents.
In various domestic electrical appliances and industrial eletrical equipments, it was important for enhancing the efficiency of a power supply that an effective correction-technique was adopted to enhance power factor and to gain more active power.
Take specific instance illustrating that low voltage reactive compensation technique can enhance power factor,deduce line loss,better voltage quality,improve voltage qualification rate and the power supply ability of low-pressure line and electric distributed transformer. We should attach importance to the method in village electric net reconstruction and speed up the construction.
