An Analysis Method for Power Factor Control of Transmission and Distribution Lines

Abstract

The invention relates to a power factor control analysis method for power transmission and distribution lines. The power factor control analysis method comprises the steps of collecting telemeasuring data through a power monitoring system, and calculating electric quantity through an electric energy calculation unit; determining a calculation model of power transmission and distribution line loss; performing data processing on the calculation model through an electric energy measuring apparatus to obtain a power factor of an assessment point, wherein the electric energy measuring apparatus performs data processing for one time at certain interval times; and checking the power factor of the assessment point. According to the power factor control analysis method, the power factor of the power transmission and distribution lines can be reasonably calculated and modified according to the structural characteristics of the power transmission and distribution lines; and the power factor of the assessment point can be improved and the system operation can be optimized by adopting hierarchical control and partitioning in-place balanced reactive balance adjustment means.

Description

technical field [0001] The invention relates to the technical field of energy comprehensive utilization, in particular to a power factor control analysis method for power transmission and distribution lines. Background technique [0002] The various loads of large industrial enterprises are mostly inductive, such as motors, transformers, frequency conversion equipment, etc., and the reactive power consumption is very large. The impact of this is: the output active power of the system generator is reduced, and the power transformation and transmission are reduced. The power supply capacity of the facility increases the loss of the power supply network and increases the voltage drop of the transmission line. In view of the fact that the level of power factor has an important impact on the full utilization of power generation, power supply and power consumption equipment, power saving and voltage quality improvement, the power grid company has formulated power factor reward and...
