Study on Reactive Power Optimization Compensation for 35 kV Overhead Transmission Lines
In order to achieve the best reactive power optimization compensation effect for 35 kV overhead transmission lines,improve voltage quality,and enhance the stability of overhead transmission lines,a reactive power optimization compensation method for 35 kV overhead transmission lines is proposed.This method first determines the improvement of voltage stability as the objective of reactive power optimization compensation for the transmission line,analyzes the distri-bution and trend of reactive power loads on transmission lines,and calculates the optimized compensation capacity for re-active power on the lines.It then adopts the principle of series capacitor compensation to offset the partial line reactance of 35 kV overhead transmission lines,reduces the voltage loss caused by line reactance,and achieves the goal of reactive power optimization compensation.The experimental results show that the application of the proposed method makes the maximum voltage deviation controlled within 0.33％,and improves the voltage quality of 35 kV overhead transmission lines.
