Accompanying drawing explanation
Fig. 1 is system schematic of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, transformer voltage ratio intelligence measuring equipment, comprise controller, the data that the remote-terminal unit (RTU) at transformer two ends gathers send to described controller; Described controller communicates with Zhan Kong center respectively with regulation and control center; Synchronous clock module is controller time service; Stabilized voltage supply is that synchronous clock module and controller are powered; Described controller completes the calculating of transformer voltage ratio according to the data of remote-terminal unit collection.
Wherein, controller adopts single-chip microcomputer, and the model of single-chip microcomputer (MicrocontrollersUnit) is the ARM single-chip microcomputer of stm32, and this single-chip microcomputer, for the treatment of signal, completes the calculating of transformer voltage ratio.
Synchronous clock module selects GPS/ Big Dipper dual-mode receiver and antenna, for regulation device provides synchronous clock.
Remote-terminal unit and controller adopt first network module to communicate.Controller and regulation and control center adopt second network module to communicate.Second network module and first network module select W5500 ethernet network module, complete the exchanges data at RTU and single-chip microcomputer and single-chip microcomputer and regulation and control center.
Controller and Zhan Kong center adopt wireless module to communicate.Wireless module model is CC2530, uses Zigbee communication agreement, and function is send wireless signal to Zhan Kong center.
Stabilized voltage supply, model is A-200-5, and input 220V alternating current, exports the direct current of 5V.Stabilized voltage supply provides power supply respectively to synchronous clock module, first network module, second network module, wireless module and single-chip microcomputer.
Single-chip microcomputer is also connected with alarm, reports to the police when in the actual no-load voltage ratio of transformer with regulation and control central database, no-load voltage ratio is inconsistent.
The principle of work of transformer voltage ratio intelligence measuring equipment of the present utility model is as follows:
Synchronous clock module p.s. to single-chip microcomputer send one time lock in time data, after single-chip microcomputer receives time signal, send request of data by first network module to RTU, and send request of data by second network module to regulation and control center.RTU reply and the metric data sending current transformer two ends to single-chip microcomputer, regulation and control center answer also sends transformer voltage ratio Ncr to single-chip microcomputer.After single-chip microcomputer receives the metric data at transformer two ends, can according to the actual no-load voltage ratio n of metric data calculating transformer.Therefore, the actual no-load voltage ratio of transformer and the transformer voltage ratio in regulation and control central database can be obtained.According to the actual conditions of transformer, the threshold value scope ε of the no-load voltage ratio parameter error of transformer is set, when
time, Boolean type variable s is set to 1, represents that this transformer actual parameter is consistent with the parameter in regulation and control central database; When
time, Boolean type variable s is set to 0, represents that this transformer actual parameter is inconsistent with the parameter in regulation and control central database.The data of gained are carried out packing and send to regulation and control center and Zhan Kong center.Data are the form of ASCII character, and its form is:
| Time | Boolean type variable | Actual no-load voltage ratio |
Such as, the actual no-load voltage ratio of transformer in 11: 35: 26 on the 12nd November in 2015 is 0.9775, and Boolean type variable is 0, then data are packaged as:
| 20151112113526 | 0 | 0.9775 |
After data packing, data are sent packet by second network module to regulation and control center, if Boolean type variable is 0, then also need to send alerting signal by wireless module to Zhan Kong center.After Zhan Kong center receives the report for police service signal, contact with regulation and control center, judgement need reset transformer parameter or change regulation and control center transformer voltage ratio parameter value, to guarantee that the actual no-load voltage ratio of transformer is identical with the transformer voltage ratio in regulation and control central database.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
