Abstract
The invention provides a distributed type intelligent reactive compensation box, relates to a reactive compensation device, and in particular relates to a distributed type intelligent reactive compensation device which is applicable to being mounted at the terminal of a distribution line of a rural power grid and meter box incoming line ends of residential quarter apartments, high-rise residential building floors and office floors of cities and towns. The device can save energy and reduce loss, and takes a controller as a core; and automatic tracking compensation and manual compensation can be realized according to the reactive distribution condition of a system. Not only can output of a transformer be improved, but also a power factor of a user is improved, the voltage quality of the terminal of the line is improved and the line loss is reduced. The inner part of the distributed type intelligent reactive compensation box utilizes an advanced alternative-current sampling reactive controller and a reliable cylindrical capacitor, and a capacitor switching device utilizes a novel intelligent alternative-current contactor, so that the switching of the capacitor is more reliable. The device provided by the invention can be used for displaying average values of current, voltage, power factors and harmonic distortion, switching states of the capacitor and the like.
Description
Technical field
The present invention relates to a kind of reactive power compensator, refer in particular to the dispersed intelligence reactive power compensator of the table case end of incoming cables that is applicable to residential quarter self-contained flat, the high residential building floor that is installed in rural power grids distribution line end and cities and towns, the floor of handling official business.
Background technology
At present, the reactive power compensation of known distribution line all is employed in transformer leading-out terminal centralized compensation, and its advantage is that the building-out capacitor capacity is big, can improve transformer and exert oneself.Descend to the terminal voltage quality that produces owing to line loss the user but can't solve from the transformer leading-out terminal.
Summary of the invention
In order to overcome existing line loss and the deficiency of terminal voltage quality from the transformer to the user side; The present invention provides a kind of novel compensator; This product promptly can be realized the compensation of transformer leading-out terminal, improves transformer and exerts oneself, and also can be installed in line end; To the load local compensation, improve user's power factor.
The technical solution adopted for the present invention to solve the technical problems is: this device adopts the distributing design; And have the intelligent powerless compensation function, inner AC sampling reactive controller and the reliable cylindrical electric capacity that adopts the advanced person of device designs according to the user power utilization characteristics; Can realize the three-phase compensation; Reasonably compensation capacity and capacitance allocative decision improve the user side quality of voltage, really public change distribution line line loss are reduced to minimum.The selection of sampling physical quantity is to calculate according to the data of the reactive power actual acquisition of field apparatus, realizes the automatic switching of electric capacity.Controller calculates the actual load or burden without work in scene according to I, the U of sampling, judges according to on-the-spot actual reactive power and the actual output of electrical network reactive power situation how much idle needs are mended.Mend how many idle desired values of wanting to realize power factor with the user that depend on, for example: desired value is 0.98, and device is just according to this target power factor so; It is idle to calculate target; Then according to the voltage at scene, electric current, power factor calculates the reactive power of on-site real-time.When measured power factor hysteresis target power factor, the reactive power of actual measurement compensates greater than dropping into first group of electric capacity after the settings of first group capacitor automatically, circulating according to this after deducting target power then, up to reaching set target power factor.Behind the leading target power factor of measured power factor, can excise electric capacity automatically.
The invention has the beneficial effects as follows and can realize three-phase compensation or phase splitting compensation function according to the design of user power utilization characteristics, reasonably compensation capacity and capacitance allocative decision improve the user side quality of voltage, really public change distribution line line loss are reduced to minimum.
