Description

Automatic check-in system of primary equipment locking logic of transformer substation
Technical Field
The invention relates to the field of substations, in particular to a substation primary equipment locking logic automatic acceptance system.
Background
In recent years, an anti-misoperation system is widely applied in the power industry as an effective technical means for preventing electrical misoperation accidents of a transformer substation. The core of the misoperation prevention system is locking (electric locking, mechanical locking and signal locking after abnormal signals are sent out) logic, and whether the logic is set is directly related to the safety of the electric operation of the transformer substation; if the locking logic condition is missing and the criterion is imperfect, the error preventing function is imperfect directly, so that misoperation safety accidents can be caused. Therefore, effective checking and acceptance of the misoperation-preventive locking logic is an important precondition for ensuring correct operation of the misoperation-preventive system and ensuring misoperation prevention of the electric appliance.
At present, an automatic acceptance correlation method through a logic formula exists in a microcomputer misoperation prevention system of a transformer substation, but the verification is only carried out on the logic formula of microcomputer misoperation prevention locking, and other equipment involved in locking logic of certain equipment cannot be subjected to association control or state reading operation. The locking logic of the primary equipment still needs to be manually operated and checked step by step.
Through manual operation and inspection, the following defects exist: (1) And (3) manually checking operation item by item, wherein the states of equipment mechanisms and the like are not in a normal state because the transformer substation is still under construction. In order to verify the locking logic, some mechanisms are required to be in the states of pressing, opening and the like, and at the moment, a plurality of persons are often required to cooperate with different devices (for example, a plurality of persons make the devices meet a certain verification condition, and another person operates on a panel), so that manpower waste is caused, and the acceptance efficiency is low; (2) The manual inspection has uncertain human factors, which is easy to cause the problems of partial equipment missing inspection, logic condition missing related equipment data and the like; (3) In order to ensure the consistency of the acceptance effect, a large amount of materials are prepared and acceptance personnel are uniformly trained in the early stage; (4) The locking verification of a special operation mode is relatively complex, and the manual inspection is difficult, time-consuming and labor-consuming in different rooms and even floors (such as each side of a transformer, a capacitor switch and a body, and a grounding variable switch and a body) of related equipment.
In summary, in the prior art, there is no automatic checking method for preventing the locking of the primary device itself from being mistakenly checked; or, the existing automatic check only checks a logic formula of microcomputer misoperation-preventive locking, and can not perform associated control or state reading operation on other equipment related to a certain equipment locking logic; the complicated work of locking logic acceptance of primary equipment of a transformer substation is caused, and the problems of low efficiency and low accuracy exist.
