Optimization Study Of Reactive Power Compensation For Rural Medium-voltage Distribution Line

The radius of rural medium voltage distribution lines is long, and the natural power factor is low. The transmission of a large number of reactive power declines the voltage quality and increases the consumption of power. Study the algorithm of distribution lines reactive power compensation and take effectively reactive power compensation measures can improve the line voltage, reducing line losses and obtain economic benefit.This paper presents a precise calculating method of single-supply distribution lines` reactive power compensation. To meet the voltage qualification rate for the first constraint, minimize power loss as the goal and considering compensation equipment investment and running costs, seek the cost-benefit compensation program. The calculation of rural medium-voltage distribution lines reactive power compensation scheme gets a true conclusion. This theory can guide the choice of reactive power compensation scheme.
