Abstract
The present utility model relates to a main controller for an active filter. The main controller is respectively connected with a plurality of power units, the main controller comprises a control plate, and a power supply, a signal switching plate and an optical fiber switching plate connected with the control plate, the optical fiber switching plate is respectively connected with the power units through optical fibers; the power supply is also connected with the signal switching plate; and the control plate also comprises an RS485 interface module. The main controller can be used for connecting a plurality of active filters in parallel and coordinating and controlling the filters, thus flexible configuration of the active filters of different capacities can be realized, and on-site capacity expanding is more convenient.
Description
Technical field
The utility model relates to a kind of master controller that is used for active filter.
Background technology
Along with the fast development that modernized factory produces, electric load sharply increases, and load capacities such as the various RHVCs in the electrical network, rectifier constantly increase.A large amount of power electronic power devices and device are in the extensive use of electrical network; When bringing energy-conservation and power conversion, cause serious pollution also for the supply network quality of power supply, a large amount of harmonic waves and reactive current injection electric power system to plant produced; Cause the system effectiveness step-down; The power factor variation, and to other equipment and device generation disturbance, the quality of power supply of serious threat electrical network and the safe operation of power equipment; Therefore electric energy quality test is an important content of electric power netting safe running evaluation and research, and harmonic problem is distinct issues.
Administer the normal mode that adds the filter filtering that adopts of harmonic wave, except that passive filter, also obtain increasing approval and application based on the active filter of dynamic compensation.The existing power active filter basically all is the form of single cabinet, installs to be single cabinet, in application, usually can run into: when adopting two or more active filter parallel connections with dilatation, have the problem that is difficult to united and coordinating control between each device.
Therefore, how to realize that the be together in parallel active filter master controller of coordinated operation of a plurality of active filters is one of those skilled in the art's direction of being devoted to study.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art and a kind of master controller that is used for active filter is provided, and this master controller can be realized the coordinated operation that is together in parallel of a plurality of active filters.
The purpose of the utility model is achieved in that
A kind of master controller that is used for active filter of the utility model, this master controller links to each other with several power cells respectively, and it comprises control board and the power supply, Signals Transfer Board and the optical fiber keyset that are attached thereto, wherein,
Described optical fiber keyset links to each other with several power cells respectively through optical fiber;
Described power supply also links to each other with described Signals Transfer Board;
Described control board comprises the RS485 interface module.
The utility model main controller can be realized a plurality of active filters are together in parallel, and in addition united and coordinating control, can realize the flexible configuration of different capabilities active filter thus, thereby makes that on-the-spot dilatation is more convenient.
Description of drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
See also Fig. 1, the master controller that the utility model is used for active filter has been shown among the figure, this master controller 1 comprises control board 2 and the power supply 3, Signals Transfer Board 4 and the optical fiber keyset 5 that are attached thereto, wherein,
Optical fiber keyset 5 is connected through optical fiber with five power cells 6 respectively;
Power supply 3 also links to each other with Signals Transfer Board 4, and power supply 3 links to each other with electrical network;
Control board 2 comprises RS485 interface module 21, and control board 2 is connected with remote equipment with local interface respectively through these RS 485 interface modules 21.
Control board 2 is connected through a plurality of power cells 6 of optical fiber keyset 5 with parallel connection, realizes the control to a plurality of power cell 6 united and coordinating, but the active filter of flexible configuration different capabilities thus, thus the dilatation at feasible scene is more convenient.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
