电力用户无功就地补偿的好处有:1 实行力率收费,可减少电费支出.2 减少了电能损失.因为△P=(P/Ucosφ)~2×R,所以△P与力率的平方成反比,故用户的力率从O.7提高到O.95,功率损失可减少46%,如从O.7提高到O.9O,则可减少4O%.效果是明显的,因此,提高用户力率是节约电能的重大措施.
The advantages of reactive power compensation in power users are: 1 The implementation of power charges, can reduce electricity costs .2 Reduce the power loss. Because △ P = (P / Ucosφ) ~ 2 × R, △ P and force square Is inversely proportional to, so the user’s force increased from O.7 to O.95, the power loss can be reduced by 46%, such as from O.7 to O.9O, can be reduced by 4O%. The effect is obvious, therefore, to improve User force is a major measure to save energy.
