对农村低压用户(包括村级电网)进行无功补偿,用户到底能得到哪些好处呢?1 能够减少低压线路的有功损耗,从而达到降损节能的目的.当电流通过低压线路时,其有功功率的损失△P=3(P~2R/U~2)·1/cos~2(?)×10~(-3)从式中可以看出,有功功率的损耗△P是与功率因数cos(?)的平方成反比关系.当功率因数cos(?)提高时,式中1/(cos~2(?))的值就小,它与3(P~2R)/U~2的积同时减小(即 What are the benefits that users can get from reactive power compensation for low-voltage users in rural areas (including village-level power grids)? 1 The active loss of low-voltage lines can be reduced so as to reduce the energy loss. When the current passes through the low-voltage lines, (P ~ 2R / U ~ 2) · 1 / cos ~ 2 (?) × 10 ~ (-3) It can be seen from the formula that the loss of active power ΔP is proportional to the power factor cos ( When the power factor cos (?) Is increased, the value of 1 / (cos ~ 2 (?)) Is small and the product of 3 (P ~ 2R) / U ~ 2 is simultaneously Reduce (ie
