On the low-voltage reactive power compensation

Reactive load and power factor cOs value, comprehensive analysis of load conditions to select several largest capacity, and the reactive load the installation of large low voltage transformer reactive power compensation devices. I used this method Bureau of soaring substation 10kV line on the three low-voltage transformer compensation, access to good results, compensating device installation point COSqb value from 0.72 to 0.82 increased to 0.94 ~ 0.98,10 kV line first Duanyou 0.72 to 079, increased to 0.92 ~ 0.96. 3.3 10kV power supply in the rural power lines, and the transformer Range of distribution transformers and more power to villages, Tuen as a unit,[link widoczny dla zalogowanych], a village, Tuen one or two power processing points. Should be adopted in such circumstances as to compensate and random way of compensation, respectively. The low voltage side of transformer load current calculated by selected shunt capacitor compensation, in the capacity of rural processing point plan selection by motor capacitor compensation. Compensation capacitors manually switching the way, can greatly reduce the investment. Only such a low investment, large-scale dispersion compensation of reactive power in order to reduce the line losses of rural power lines,[link widoczny dla zalogowanych], while reducing electricity bills of farmers, but also reduce the burden on peasants. 3.4 Characteristics of rural irrigation and drainage station power: First, The second is Also put into operation a number of irrigation and drainage in rural areas,[link widoczny dla zalogowanych], there is bound to reactive power peak. To this end, the irrigation and drainage stations must be calculated according to motor capacity randomly selected shunt capacitor compensation, short-term balance of a large number of local reactive power, peak load reduction of reactive power. 4 low-voltage reactive power compensation device measuring device measuring point wiring devices the main point is to compensate for the introduction of capacitors and the current point, in particular the introduction of the current point in the actual wiring is often overlooked. The introduction of point capacitor, capacitor means the total compensation into line in the system by The correct way is: to load the power supply as a reference point,[link widoczny dla zalogowanych], current transformer installation point must be the total capacitor into the line Group of current, otherwise, the group voted in the capacitor, cut state, the reactive power compensation device measurements show that the active and reactive power and COSqb value will not change, resulting in reactive power compensation device to vote, can not determine the effect of cutting. This issue should be pay attention, otherwise the installation process will inevitably lead to frustration. 5 to strengthen the assessment of reactive power user power supply current stag to focus on marketing the recovery of electricity, reactive power evaluation do not care, or because the user does not pay out electricity to accommodate the requirements of the users of reactive, required a lot of reactive power meter should be installed in the distribution transformers are equipped with the installation. Therefore, we should strengthen the reactive power of the user assessment efforts, according to the relevant provisions of the State Power Corporation , power factor COSqb value of less than standard of compensation should be urging the installation of devices to reduce line losses and electricity. to benefit both users and power supply system.
