In order to improve the utilization of power and decrease the loss of transmission lines, it is of gloat significance to improve the power factor. The Multisim simulation technology was applied to the power factor improvement. In the principle of ensuring that the inductive load rated working condition is constant, the power factor of the whole line was improved by the parallel capacitor. The power factor and circuit current of the test circuit were simulated in parallel different capacitors and the simulation research was applied to the actual circuit. The practice shows that Multisim simulation has advantages in circuit design. It shows the effect of parallel capacitance on line current and power factor intuitively. It also plays a guiding role in the design and implementation of the power factor of the actual circuit. The method of increasing the power factor of the inductive load is convenient and effective by the parallel capacitance.
