Embodiment Construction

[0032] Figure 1 to Figure 6 Describes the method of saving power and grid investment by improving the power factor.

[0033] figure 1 First, the sampling module (a) collects the voltage and current values ​​from the power grid, and sends the phase relationship signal changes between the operating voltage and current of the electrical equipment in the power grid to the computer processing system (b).

[0034] figure 1 The computer processing system in (b) performs a series of amplification and transformation processing on the analog signal sent by the sampling module (a) to generate digital control instructions. Assign a value to the power factor in the grid in the system control program, such as cosφ=0.99. If it deviates from this value, the phase difference between the voltage and current sent by the sampling module (a) (see Figure 3 to Figure 6 ) Immediately reflect the power factor value in the power grid, the computer processing system (b) will automatically perform calc...

Abstract

This invention discloses one method to realize energy saving and electricity net investing through improving the power factors, which reduces the electricity capacity of all apparatus and the low investing of the electricity net and realizes energy saving rate of 15~30 % and improves the power factor of cosphi=0.95~0.99. The solution comprises the following points: it forms the mutual power factor correction compensation system by several compensation units and combined with strong power and weak power and with advanced computer technique, element to realize the compound power compensation.

Description

Technical field [0001] The invention relates to the whole process of power generation in the alternating current power industry, which improves the power factor of various electrical equipment used in factories, mines, enterprises, agriculture, municipal administration, commercial use, and civil use. Background technique [0002] Among the existing power-saving technologies, there are relatively few practical applications and technologies for improving the power factor through compound compensation technology, and most of them are for a certain electrical equipment and adopt a single compensation technology to implement a single power-saving method. [0003] Increasing the power factor can obtain the following economic and social benefits: [0004] Reduce the current in the power grid, achieve the effective reduction of the active power loss of electrical equipment and lines, and achieve the purpose of saving power; [0005] Reduce the capacity of all power transmission, transfor...
