Abstract
The said device measures consumed electric energy sectionally via the measurement of power network freq and its freq range. The present invention provides measuring method for power network management.
Description
91111616.8 number patented claim has proposed with the technology of electrical network frequency control scatteredload but this technology is not mentioned and utilized mains frequency to carry out the explanation of electric energy metrical.
Task of the present invention is the electric power meter of a kind of special applications of invention, and it will start the electric energy metrical unit of its affiliated frequency zones according to the actual frequency of electrical network, finish the metering of the real consuming electric power of each frequency zones.
The present invention is achieved in that the frequency zones of being set some regulations by management of power use department as required, and measures with one of following two kinds of methods according to frequency;
The first has a grid frequency measurement unit and a plurality of electric energy metricals unit.When frequency measurement unit records actual frequency in certain frequency zones, only start the electric energy metrical unit corresponding with this frequency zones, each electric energy metrical unit will write down the total amount of respective frequencies district power consumption with it like this.
It two is a frequency measurement unit to be arranged, electric energy metrical unit and recording processing unit.Electric energy metrical unit wherein, all the time all send the real consumption information frequency measurement unit of electric energy then according to the frequency zones under the practical frequency to the recording processing unit, control the flow direction of the real consumption information of sending the electric energy metrical unit of electric energy respectively, the real consumption information of electric energy is delivered to the electric energy accumulated unit corresponding with carving frequency zones add up, store and handle.Each accumulated unit will write down the total amount of the power consumption in respective frequencies district with it like this
The present invention has frequency measurement unit and electric energy metrical unit, it is characterized in that:
A. the frequency measurement unit foundation is judged each frequency zones of affiliated regulation constantly to the measurement of electrical network actual frequency,
B. according to the frequency zones of being judged, in the electric energy metrical unit corresponding, add up the real consuming electric power in per moment with this frequency zones.
The present invention is by the measurement to the electrical network actual frequency, the branch frequency zones has been carried out the metering of real consuming electric power, method is simple, and it carries out appraisal management for administration of power networks according to frequency provides measurement means, can be widely used in industrial and mining enterprise unit etc. and carry out the frequency partition metering.
Claims (2)
1, a kind of is the device that carries out electric energy metrical according to subregion with mains frequency, and frequency measurement unit and electric energy metrical unit are arranged, and it is characterized in that:
A. frequency measurement unit is judged the frequency zones of the regulation under each is constantly according to the measurement to the electrical network actual frequency,
B. according to the frequency zones of being judged, in the electric energy metrical unit corresponding, add up the real consuming electric power in per moment with this frequency zones.
2, according to the metering method of the described electric power meter of claim 1, it is characterized in that one of following dual mode:
A. when frequency measurement unit records actual frequency in certain frequency zones, only start the electric energy metrical unit corresponding with this frequency,
B. electric energy metrical unit all sends the real consumption information of electric energy all the time, and by frequency measurement unit according to practical frequency, its electric energy accumulated unit of delivering to the respective frequencies district added up and handle
