Description
Technical field
A reactive power compensator for collecting and distributing type, relates to a kind of reactive power compensation technology, collecting and distributing type control method is applied in reactive power compensation specifically by 3G communication link.
Background technology
The starting point of the reactive power compensation that current China produces also is placed on user side, namely only notes the power factor compensating user, and ignores the power consumption of electrical network.Many times this kind of mode is unreasonable due to what compensate, easily causes the situation of reactive power releasing to occur.But the situation in order to avoid reactive power releasing occurs that some device can switched capacitor frequently, and the consequence of frequent switching can cause throw in-of oscillation again, namely reduces the life-span of capacitor, causes very large impact again on the stability of a system.Day by day ripe along with the 3G network communication technology, coverage rate is wide again, and the idle situation that the wireless network that interest concessions mobile operator provides gathers major network and electricity consumption branch road becomes a reality in the mode realizing collecting and distributing type and control.
Utility model content
The present invention is the weak point for existing in above-mentioned prior art, provides a kind of and compensates rational collecting and distributing type reactive power compensator, more rationally, more effectively to realize no-power compensation function.Its structural scheme is as follows:
1, a kind of reactive power compensator of collecting and distributing type, it comprises, and major network gathers control unit, branch road gathers control unit and compensating unit, it is characterized in that described major network is gathered control unit and communicated by 3G communication link with branch road collection control unit, and described compensating unit is divided into major network and branch road two parts, they gather control unit respectively by drive circuit and major network and gather control unit with branch road and be connected.
2, described major network collection control unit is made up of acquisition control module, output driving circuit and 3G module, the collection terminal of described acquisition control module is connected with entrance bus-bar potential transformer summation current transformer by wire, the other end directly connects output driving circuit, and 3G module is then connected with acquisition control module by serial line interface; Its role is to acquisition control module by gathering each phase electric parameter information at entrance bus place, to obtain the idle situation of current system, obtain by 3G communication link the idle situation that current each branch road gathers control unit simultaneously, and in conjunction with the idle situation in current entry bus place, complete the formulation of compensation policy, controlling output driving circuit according to compensation policy drives compensating unit to compensate, and is transmitted control signal to branch road collection control unit by 3G module;
Described branch road gathers control unit and is made up of acquisition control module, output driving circuit and 3G module equally, just the collection terminal of described acquisition control module is connected with the voltage transformer summation current transformer on electricity consumption branch road by wire, and the connected mode of output driving circuit and 3G module and major network to gather control unit identical; Its role is to acquisition control module by gathering the electric parameter information of electricity consumption branch road, to obtain the idle situation of this branch road current, and this idle situation is aggregated into major network collection control unit by 3G communication link, the formulation that control unit completes compensation policy is gathered by major network, and control signal is passed back to branch road collection control unit by 3G communication link, drive compensating unit to compensate by it by drive circuit;
Described compensating unit is divided into major network and branch road two kinds, and major network compensating unit is made up of the Reactor banks according to specific coding size, and branch road compensates by forming according to specific coding sized capacitors device group;
Described 3G module is made up of 3G assembly and photoelectric isolating circuit, the serial port of another termination 3G assembly of serial port of described photoelectric isolating circuit one termination acquisition control module, for serial communication between the two provides signal to isolate with the noiseproof feature increasing system;
The quantity that described branch road gathers control unit is relevant with the quantity of electricity consumption branch road, and major network collection control unit is unique, and the communication network namely between them gathers control unit by a major network collection control unit and several branch roads and forms.
Described compensation policy takes branch road to compensate, the mode of major network balance, gather control unit by major network the idle situation of major network and branch road is gathered, and first according to the idle situation of branch road, carry out branch road compensation, to be combined by specific coding by driving branch road compensating unit switching and Capacitor banks to realize optimized compensation.After each branch road switching is complete, all again detect major network, detect the situation whether reactive power releasing occurs, if had, provide switching coding according to the idle size sent, and drive major network compensating unit switching Reactor banks, to stop the generation of reactive power releasing according to coding.
Beneficial effect of the present invention:
Owing to having used the 3G communication technology, by with the major network of electric unit and unified the gathering of idle situation of each electricity consumption branch road, gather control unit United Dispatching by a major network, traditional local compensation has been risen to the height of global compensation.Compensation policy is more reasonable, avoids the appearance of reactive power releasing situation thoroughly.
