Description
Technical field
The present invention relates to the technical scheme of a kind of 10kV or 6kV reactive power compensation, especially relate to a kind of 10kV or 6kV transmission line reactive power compensator.
Background technology
Existing 10kV or 6kV circuit reactive power compensator, mounting points that can only harvester is the various analog quantity informations of line build-out point, and because the needs of actual compensation effect, compensation arrangement can not be installed on the leading-out terminal of circuit again, this has just caused, the analog quantity information of adopting can only react the load or burden without work situation of the later circuit of compensation point, and can not react the actual load or burden without work situation of whole piece circuit really.And at 10kV or 6kV circuit under the long or complicated situation of loading comparatively, even if this circuit has selected a plurality of compensation points to compensate, the compensation arrangement of each compensation point also can only be an independent operating separately.Caused some some overcompensation, and the still under-compensated situation of certain point, thereby the effect that compensates influenced.Existing 10kV or 6kV circuit reactive power compensator can not be realized the monitoring operation of dispatch automated system.
Summary of the invention
In order to solve the problem that above-mentioned compensation arrangement exists, the invention provides a kind of 10kV or 6kV transmission line reactive power compensator that can compensate respectively to a plurality of compensation points of transmission line.
The particular content of technical solution of the present invention is as follows:
10kV of the present invention or 6kV transmission line reactive power compensator comprise,
Concentrate measure and control device: be installed in the leading-out terminal of transmission line, be used to measure data parameters and the reactive power compensation of coordinating the terminal compensation device on the transmission line;
At least one terminal compensation device: be installed on the transmission line, and can select the installation site, transmission line is carried out reactive power compensation according to the different load situation of circuit;
First wireless network module: be installed on the described concentrated measure and control device, be used to receive the instruction of concentrating measure and control device and will instruct and send to second wireless network module by wireless network;
At least one second wireless network module: corresponding one by one with described terminal compensation device, and be installed in respectively on the corresponding terminal compensation device, be used for receiving the instruction of first wireless network module, and be transferred to corresponding terminal compensation device by wireless network.
10kV of the invention described above or 6kV transmission line reactive power compensator, described wireless network is the GPRS cordless communication network.
The present invention changes traditional compensation arrangement and carries out the way of circuit analog acquisition at compensation point, and the compensation point (being called the terminal compensation device) of compensation arrangement is separated with sampled point (being called concentrated measure and control device).Compensation point is still selected according to the actual load situation of circuit, and the selection of sampled point no longer is subjected to the constraint of compensation point position.Sampled point can or be chosen in 10kV or the leading-out terminal of 6kV transmission line at the front end of compensation point, when sampled point is chosen in 10kV or 6kV transmission line leading-out terminal, can gather real-time Simulation amount data such as the voltage that obtains the 10kV or the 6kV transmission line port of export, electric current, power factor, reactive power, active power, these data have been reacted the actual load situation of whole piece 10kV or 6kV transmission line, rather than only react the load condition of circuit behind the compensation point.The analog data of the transmission line that obtains from sampled point can be delivered on the compensation arrangement that is installed in compensation point by wireless communication networks, whether compensation arrangement compensates as these data to circuit basis for estimation, compensate the accuracy that can improve compensation according to these data, thereby improve the actual compensation effect of line build-out.Rely on wireless communication networks to carry out data passes, need not to lay separately communication line, reduced the cost that drops into.When long or line load situation is comparatively complicated at circuit, then to select a plurality of compensation points that this circuit is carried out reactive power compensation.The device that is installed on sampled point not only possesses the function of data acquisition this moment, and can carry out unified allotment to the compensation arrangement of each compensation point on the circuit, realize the optimal compensating of whole piece circuit, improved the power factor of each point in the circuit, and effectively reduced the reactive loss of circuit.
Description of drawings
Accompanying drawing 1 is a 10kV transmission line compensation scheme system schematic of the present invention
Among the figure, 1. concentrate measure and control device, 2. terminal compensation device, 3. first wireless network module, 4. second wireless network module.
Embodiment
Be illustrated in figure 1 as a kind of 10kV transmission line compensation scheme system schematic of the present invention, this technical scheme comprises a concentrated measure and control device 1, several terminal compensation devices 2, concentrate measure and control device 1 to be provided with first wireless network module 3, be respectively arranged with one second wireless network module 4 on each terminal compensation device.First wireless network module and second wireless network module adopt the GPRS communication network terminal.Wherein, concentrated measure and control device is installed on the sample point of transmission line, can realize the function of the data acquisition such as real-time voltage, electric current, power factor, reactive power, active power of circuit, but when the compensation arrangement on the circuit two or more the time each reactive power compensator of unified allocation of resources also.
The terminal compensation device is installed on the compensation point place of circuit, receives each analog data of circuit of concentrating measure and control device to gather, and controls the reactive power compensation that realizes this compensation point by the switching to the capacitor group.
Concentrate measure and control device and terminal compensation device GP configuring RS communicating terminal respectively, can utilize existing GPRS communication network to realize wireless data transmission between each device.
