Automatic closed-loop testing method for connecting-and-locking logic of substation bay level

Abstract

The invention provides an automatic closed-loop testing method for a connecting-and-locking logic of a substation bay level. The automatic closed-loop testing method comprises the steps of loading a substation configuration description (SCD) model and a bay level connecting-and-locking logic role, extracting a semaphore which is related with a tested bay level connecting-and-locking logic operation and a reference that corresponds with a logical operation result; automatically generating a connecting-and-locking logic testing task sequence, and determining a testing-and-control device in a testing scene; wherein each testing task comprises a name and a description of primary equipment of the connecting-and-locking logic test, a related semaphore, a corresponding number, an index and a connecting-and-locking logic prediction result; constructing multiple scenes which supports automatic closed-loop testing of the connecting-and-locking logic, and acquiring the connecting-and-locking logical operation result in the testing scene; and evaluating the logical operation result. The automatic closed-loop testing method is suitable for in-substation local automatic closed-loop testing and remote scheduling automatic closed-loop testing, and furthermore has functions of preventing reconstruction and expansion of device which requires power-off operation, improving testing efficiency, saving time-wasting and labor-wasting working cost in manual testing and ensuring high correctness of an error locking preventing logic.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to an automatic closed-loop testing method for substation bay layer interlocking logic. Background technique [0002] Smart substations are an important part of the construction of smart grids. Up to now, more than 1,000 smart substations have been built and put into operation by State Grid Corporation of China. In order to prevent misoperation, the five-prevention operating procedures of the substation are stipulated, that is, to prevent the wrong opening and closing of the circuit breaker, to prevent the load opening and closing of the isolating switch, to prevent the live connection (closing) of the grounding wire (grounding switch), and to prevent the grounding wire ( Grounding switch) combined with circuit breaker (isolating switch) to prevent accidental entry into the charged interval. , the five defenses at the interval layer are realized by the meas...
