Reactive power compensation controller for power

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a reactive power compensation controller for power, in particular to a device of the reactive power compensation controller applied to an electric power line. The reactive power compensation controller for power is a design of the reactive power compensation controller on the basis of an FPGA and DSP unit, and comprises a power supply unit, the FPGA and DSP unit, a key input unit, a liquid crystal display unit, a communication unit and a control unit. Automatic tracking compensation is carried out according to the change condition of a reactive power and a voltage of the line, so that the power factor is improved; the voltage quality is improved; the reactive power transmission flow of a power distribution line is reduced; the reactive power transmission distance of the power distribution line is shortened; and the reactive power compensation controller also has significant characteristics of high reliability, small size, easiness in installation, powerful function and low cost.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to an electric reactive power compensation controller, in particular to a device applied to a power line reactive power compensation controller. Background technique [0002] The rural power grid has long lines, uneven load distribution, and many compensation points to be installed. If the reactive power compensation mode of the substation is copied, it will inevitably result in large investment, ineffective compensation, and inconvenient installation and maintenance. If the compensation method of installing a fixed capacity at a fixed location is adopted, although the investment is small, without any protection, capacitor burnout accidents often occur in rural power grids with poor operating conditions, causing safety hazards to the power grid operation. [0003] Therefore, the existing reactive power compensation device basically still has the disadvantages ...

AI Technical Summary

Problems solved by technology

[0002] Rural grid lines are long, the load distribution is uneven, and there are many compensation points to be installed. If the reactive power compensation mode of the substation is copied, it will inevitably result in large investment, the compensation effect is not obvious, and installation and maintenance are inconvenient.

If the compensation method of installing fixed capacity at a fixed location is adopted, although the investment is less, without any protection, capacitor burnout accidents often occur in rural power grids with poor operating conditions, causing safety hazards to the power grid operation

[0003] Therefore, the existing reactive power compensation device basically still has the disadvantages of single function, poor stability, and low precision.
