Description

Technical Field

[0001] The invention relates to the technical field of electric power dispatching, and in particular to a logic programming verification method for a microcomputer error prevention device of a transformer substation. Background Art

[0002] Preventing misoperation is the key to preventing accidents for power system operators. Before starting operations on site, a verification simulation rehearsal should be carried out on the simulation diagram or microcomputer anti-error device or microcomputer monitoring device. After confirming that there are no errors, operations can be carried out. There are many sources of misoperation. The microcomputer anti-error device constructed using computer technology has been widely used in high-voltage switchgear, which can implement functions such as locking, simulation rehearsal, intelligent judgment, and language prompts for electrical equipment. The current microcomputer anti-error locking device locks the devices such as circuit breakers, switches, ground switches, and fence net doors. The above-mentioned devices are locked by microcomputer locks, namely electric coding locks and mechanical coding locks. The software must write operation locking rules for the above-mentioned devices, which are called the five-prevention logic rule table.

[0003] Due to the different manufacturers of microcomputer anti-error devices, the five-protection logic rule table is written in different languages. It is written by the manufacturer's technicians during the substation commissioning acceptance and equipment changes, and the operation and maintenance personnel perform manual verification. In addition, the operation and maintenance personnel are required to regularly conduct a comprehensive check of the five-protection logic of the microcomputer anti-error device to ensure that the anti-error logic is correct.

[0004] Based on the search of the above information, it can be seen that the five-defense logic detection of the microcomputer anti-error device is usually carried out by manual detection, which has the following defects:

[0005] 1. High knowledge reserve requirements for calibration personnel: Calibration personnel need to learn and master the logic languages ​​of multiple manufacturers in advance before they can read the five-defense logic rule tables written by personnel from different manufacturers. The threshold for calibration personnel is relatively high;

[0006] 2. The five-defense logic verification takes a long time: The five-defense logic rule table of the 220kV substation is complicated and needs to be checked one by one, which is time-consuming and has low work efficiency;

[0007] 3. The quality of verification is uncertain: the quality of verification is closely related to the logic language proficiency, skill level, and work responsibility of the verifier. The five-prevention rules for various equipment intervals and the logic languages ​​of various manufacturers are highly complex, and the verification accuracy rate is difficult to reach 100%. Summary of the invention

[0008] 1. Technical issues to be resolved
