Industrial enterprises of reactive pensation
From:Power System Analysis and Design
Abstract
The improvement of industrial enterprises is to improve the power factor of electric power efficiency, an important means of saving energy. In this paper, theoretical analysis and application examples of the industrial enterprises, the significance of reactive pensation and the role and view of the current power system, industrial enterprises, the problems for the proposed improvements and measures.
Introduction
In industrial enterprises, the vast majority of electrical equipment belongs to perceptual load, these devices in operation to absorb a large number of reactive power. An increase in reactive power supply system power factor to lower system voltage drop to occur, electrical equipment not fully utilized, increasing line losses and lower-powered equipment, power supply capacity and so on. In situ reactive pensation and thus improve the power factor of the Energy Conservation has extremely important significance.
The choice of method pensation
Compensation for reactive pensation is divided into centralized and pensation for three kinds pensation and in situ. Focus pensation, that is, high and low voltage power distribution set up by several groups within the capacitor, capacitor connected to the power distribution bus, pensation for the distribution of power within the reactive power, and to reach the required value of the total power factor above. This method pensation pensate for high and low voltage bus routes prior to the reactive power, which is equivalent to the reactive power source to move the electricity panies, allowing users to power the system requirements for reactive power has been reduction in the electricity sector to achieve the required power factor. And their distribution within the enterprise bus following the line of transformer and reactive pensation can not play a role, there is still a large number
