Description
Technical field
The utility model patent relates to high-vol field, refers to a kind of SVG control system especially.
Background technology
Need in network system running to carry out reactive power compensation to electrical network, to improve power factor during operation of power networks, reduce grid loss.Reactive-load compensation equipment conventional is in recent years active dynamic reactive compensation arrangement, is called for short SVG.SVG comprises the equipment such as control cubicle, power cabinet, incoming line cabinet, reactance cabinet, mainly comprises master controller etc. in control cubicle.Generally, SVG device needs to carry out communication by master controller and each power model, issues the instruction of master controller and collects the state information of each power model.A lot of power model is provided with in the power cabinet of 35kV network system SVG device.Master controller distance in power cabinet and control cubicle is all comparatively far away, and each power model in power cabinet will cause master controller respectively by communication optical fiber, and such optical fiber use amount is more, installs wiring, repair and maintenance is all not too convenient.
Utility model content
The utility model technical issues that need to address are to provide a kind of SVG device being applicable to electrical network, to overcome the problem that SVG system wiring is complicated, repair and maintenance is inconvenient of existing electrical network.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of SVG device of individual-phase control, comprise the SVG power cabinet being built-in with some power models of connecting and the master controller be connected with SVG power cabinet, insulating arthropleura in SVG power cabinet is provided with phase-division based controller, each power model in SVG power cabinet be connected to the various state information of collection power model and make the drive plate that phase-division based controller and power model communicate with one another, described drive plate communicates to connect respectively by optical fiber and phase-division based controller, and phase-division based controller is connected with master controller is communicated by two high speed fibres again.
Further concrete structure of the present utility model is:
Phase-division based controller to be also connected on a power model near insulating arthropleura and from power taking this power model.
The various state informations of power model are uploaded to phase-division based controller by drive plate, decompose simultaneously, then be handed down to each power model by optical fiber and drive plate after the master controller received is sent to the instruction of each power model by phase-division based controller.
Owing to adopting technique scheme, the technological progress acquired by the utility model is:
Phase-division based controller is arranged in power cabinet by the utility model, each power model first by Fiber connection to phase-division based controller, master controller is connected to again by two high speed fibres, therefore 2 Fiber connection are only had between each phase power cabinet of the utility model SVG device and master controller, greatly save the use of optical fiber, optical fiber wiring is convenient and swift, easy to maintenance.Phase-division based controller can use arbitrary power model for its power supply, does not need additionally to provide power supply, reduces the production cost of SVG device, convenient for installation and maintenance.
In power cabinet, the drive plate of all power models carries out communication by optical fiber and phase-division based controller, and the state information of phase-division based controller receiver module, is uploaded to master controller by optical fiber after gathering.Phase-division based controller and master controller also carry out communication by optical fiber.Phase-division based controller receives after master controller sends to the instruction of modules decomposes, then is handed down to each power model by optical fiber.Phase-division based controller is arranged on power cabinet side plate, is connected on a power model of insulating arthropleura from power taking this power model.Guarantee phase-division based controller and this power model equipotential, without the need to considering dielectric voltage withstand problem (high pressure insulation against ground problem need be considered from external electricity).
Phase-division based controller is arranged on power cabinet interior plate, if the power supply of phase-division based controller is from other local power takings, needs to consider High-Voltage Insulation problem.Power taking from the drive plate of a power model near insulating arthropleura, power model drive plate is equal with this module high voltage circuit pack current potential, and phase-division based controller current potential is also identical therewith.Therefore High-Voltage Insulation problem of withstand voltage need not be considered.Phase-division based controller passes through optical-fibre communications with this phase power model drive plate and master controller respectively, and phase-division based controller receives the instruction of master controller, is handed down to each power model drive plate of this phase respectively.In addition, phase-division based controller also receives the state information of each power model drive plate, is then uploaded to master controller.
