Abstract:

According to the specific characteristics of the 10 kV distribution line of the power system, the sensitivity analysis technique is used to calculate the reactive power compensation. From the perspective of practical application, the composition of optimization problems, the calculation of power loss and voltage distribution, and the treatment of load shape coefficient are described. The calculation and application of sensitivity coefficient and the determination of the final scheme of reactive power compensation are introduced in detail. Based on the calculation of dozens of actual 10 kV lines, it is explained, analyzed and discussed. The sensitivity of the reactive power injection of the node is estimated and ranked by using the economic objective function, and then the accurate trial calculation is only for a limited number of schemes. The positioning of the capacitor in the 10 kV distribution line and the determination of the optimal compensation amount are completed on the basis of considering the actual capacity and group of the capacitor.
