Fig. 2 is the flow chart of the primary processor air-cooled control logic of operation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As it is shown in figure 1, intelligent transformer type electronic controller is gathered from in-site modeling signals such as the oil level of converter power transformer, pressure, oil temperatures by special signal collection plate；And connecting the on-off model such as the fan start-stop of converter power transformer, oil stream switch by switching input module, whole air-cooled control process, by identifying these signals, is monitored by intelligent electric sub-controller in real time；Control of export module connects described primary processor, for being controlled the conjunction point of oil stream switch and the start-stop of fan by the relay node output of control of export module；Primary processor connects described signal acquiring board and switching input module, according to the in-site modeling signals such as the oil level of converter power transformer, the pressure input parameter as air-cooled control logic, by running air-cooled control logic and controlling fan and oil stream switch by exporting accordingly, and gather the on-off model such as the fan start-stop of converter power transformer, oil stream switch by switching input module, thus whole air-cooled control logic is controlled.
The present invention possesses ethernet communication module, connect described primary processor, for realizing the ethernet communication function of intelligent transformer type electronic controller, communication is carried out with control centre, the status informations such as the oil level of transformator, pressure and fan start-stop are sent to control centre, and receive the control command that control centre issues, facilitate operator on duty's heart in the controlling that the running status of transformator is monitored.Touch screen as man-machine interface, facilitates operations staff checking the running status of transformator and deciliter being controlled the start-stop of fan and oil stream switch on the spot.Present invention employs IEC61850 communication protocol, carry out the collection of data and data on give.The data collected are supplied to some senior application in device, it is simple to the analysis of the local running status to converter power transformer, can also be transmitted to control centre simultaneously.
The present invention has air-cooled control function, opens into state and correlation measure by collecting, and air-cooled control processes according to respective logic, and air-cooled control configurable prediction focus, top oil, winding temperature and 4 kinds of logics of transformer load automatically control.Local and far-end both of which are also supported in air-cooled control simultaneously.
Intelligent transformer electronic controller is by gathering the collection of the relevant operational factor of transformator and corresponding logical judgment, it is recognized that the running status that transformator is current, and control accordingly for different running statuses, such as transformer temperature is too high, can automatically start air-cooled control, it is ensured that transformator normally runs.The data collected can also be uploaded to monitoring unified platform, it is simple to monitoring operations staff understands in the long-range running status for transformator, can also control accordingly in the distance simultaneously simultaneously,
In application process of the present invention, comprise the following steps (as shown in Figure 2):
1) primary processor is received from in-site modeling signals such as the oil level of converter power transformer, pressure, oil temperatures by signal acquiring board；
2) primary processor receives the on-off state such as the fan start-stop from converter power transformer, oil stream switch by switching input module；
3) primary processor performs air-cooled control logic, circulates following control process:
Step1: scan transformer running status, if transformator is stopped transport, repeats Step1, puts into operation, continue Step2；
Step2: scanning air-cooling control module state, if being manual mode, repeating Step2, automatically then continuing 3；
Step3: scanning assigned switch amount protection signal, if receiving master control to send this signal, excising all air-cooled, otherwise continuing Step4；
Step4: scanning survey sampling abnormality mark, if data acquisition is abnormal, starts all air-cooled, otherwise continues Step5；
Step5: scanning traversal cycle timeout flag, if the cycle arrives, starts whole air-cooled maintenance setting time, otherwise continues Step6；
Step6 :/strong bounce number is thrown by force in a scanning distant place, if receiving master control to send this signal, it is air-cooled to throw/move back appointment, otherwise continues Step7；
Step7: scanning automatically controls cycle timeout flag, if the cycle arrives, enters and automatically controls logic, otherwise continue Step1；
Step8: extrapolate hot spot temperature of winding according to IEC60076-7 (2005) and GB/T1094.7-2008 oil-immersed power transformer load directive/guide, transformator operating load is calculated according to load tap changer gear and source side winding CT galvanometer, the transformer top oil gathered according to measuring unit and winding temperature, carry out logical operations with each group cooler start and stop definite value set, draw the cooler number that currently should start or stop；
Step9: the cooler that the statistics according to each cooler operation time, the cooler of startup optimization shortest time or time out of service are the longest；
Step10: automatically control logic and complete, updates cooler state and continues Step1.
According to above-mentioned steps, the software principle of main operation controller is prior art.In prior art, being realized by industrial general controllers such as PLC, inefficient autgmentability is not strong.
