Abstract

The invention relates to a five-prevention interlocking measurement and control method and system, and the method comprises the steps: collecting the operation numerical information and operation state information of a plurality of electrical devices and a power grid line, and the electrical devices are disposed in the power grid line. And selecting the basic logic elements, and connecting the basic logic elements to edit the logic relationship. And according to the operation numerical value information, the operation state information and the logic relationship, performing logic judgment to generate a judgment result, and displaying the operation state of the logic relationship in real time. And comparing the judgment result with an expected result, and if the judgment result is consistent with the expected result, outputting the judgment result. The basic logics are combined in a line connection mode, and a more complex logic relation is formed. And the expression of the logic relationship is more visual and clear. The operation state of the logic relation can be displayed in real time. And nodes with logic anomalies can be found and corrected in time.

Description

technical field [0001] This application relates to the field of substations, in particular to the field of measurement and control of five-proof interlocking locking. Background technique [0002] The five-prevention interlocking system is one of the important functions to ensure the safe operation of the substation, which can effectively avoid the occurrence of human error. Due to the good stability of the five-proof interlocking locking system, it can effectively reduce the probability of accidents. Especially in the current situation that the reliability of power supply is increasingly required, the importance of the five-proof interlocking system in the operation of the substation is effectively reflected. [0003] The five-prevention interlocking interlocking of the bay layer in the on-line five-prevention interlocking interlocking system of the substation is usually realized by a measurement and control device. The power grid line connected to the measurement and con...
