And the relay protection device display interface displays the conditions of all the terminals of the relay protection device with the selected model.
Further, referring to FIG. 5, in order to more clearly illustrate the present invention, the present invention will be further described below by using a preferred embodiment of the present invention. The preferred embodiment of the invention is to utilize the relay protection experimental set to carry out the operation characteristic experiment of the DL-32 type current relay,
the specific test process is as follows:
1. the method comprises the steps of opening a computer 1 and a computer 2, respectively entering main programs of the computer 1 and the computer 2, then selecting a relay protection device needing to be tested on the computer 2, wherein a DL-32 type current relay is selected, and at the moment, displaying the display screen 1 and the display screen 2 according to relay protection test requirements (programs are set in advance), so that hardware identification of a virtual instrument is clearer.
2. According to the experiment principle, the display screen 1 and the display screen 2 are connected, specifically, as shown In fig. 5, terminals 8, 2, 1 and 3 of the data acquisition card 2 are respectively connected with terminals Ia, in, X1 and X2 of the data acquisition card 1, a terminal 4 of the data acquisition card 2 is connected with a terminal 6, normally open contacts 1 and 2 of the data acquisition card 3 are respectively connected with terminals Y5-1 and Y5-2 of the data acquisition card 5, and normally open contacts 1 and 4 of the data acquisition card 4 are respectively connected with terminals Y6-1 and Y6-4 of the data acquisition card 6.
3. After the wiring is finished, a 'pre-detection' button in the interface at the moment of the computer 1 is clicked, and the computer 2 is scheduled to perform according to a preset program at the moment as the computer 1 and the computer 2 have a communication relation. Program control in the computer 2 causes the terminals on the data acquisition card 6 to: y6-1 and Y6-4 produce currents with different magnitudes, such as 5mA for Y6-1 and 10mA for Y6-4. Normally open contacts 1 and 2 of the data acquisition card 3 are closed, and normally open contacts 1 and 4 of the data acquisition card 4 are closed. At this time, if the operator is correctly wired, the terminal Y5-1 of the data acquisition card 5 receives a current of 10mA, the terminal Y5-2 receives a current of 5mA, and the data acquisition card 5 transmits the data to the computer 1. When a preset judgment program in the computer 1 receives 10mA current from the terminal Y5-1 of the data acquisition card 5 and 5mA current from the terminal Y5-2, the judgment is that the wiring is correct, otherwise, the wiring is wrong.
4. If the computer 1 determines that the wiring is wrong, the laboratory operator needs to check the wiring, check and adjust the wiring and then perform the above steps until the wiring is correct. If the computer 1 judges that the wiring is correct, the experiment operator is prompted and the next step can be carried out.
5. After the 'pre-detection' is finished according to the prompt of the computer, a 'start experiment' button is pressed, at the moment, the current does not occur on the data acquisition card 6 any more, and the normally open contacts of the data acquisition card 3 and the data acquisition card 4 are opened again. The data acquisition card 1 is controlled by the program of the computer 1, and can carry out normal experiments by adding corresponding current.
By carrying out wiring check before starting the test, the virtual relay protection device can be protected from burning out hardware due to wiring errors.
In the above detection, only the wiring of Ia and In is detected to be correct because the two terminals bit currents can damage the instrument if the wiring is wrong, and even if the passive terminal is wrong, a fatal error which can damage the component can not be generated. The design is that the detection is not carried out, firstly, hardware can be saved, and secondly, because a wiring method in a relay protection experiment is possibly not unique, the detection can greatly occupy hardware and software resources.
The present invention is not limited to the above-described embodiments, which are merely exemplary and are intended to be illustrative of the present invention, and are not to be construed as limiting the present invention.
