Technical Field

The invention belongs to the field of electric power automation, and particularly relates to an intelligent anti-misoperation method for a transformer substation.

Background

The basic requirement of substation operation control is to prevent electrical misoperation, called misoperation for short. The five-prevention function is a core function of preventing misoperation, namely preventing a circuit breaker from being mistakenly switched off and on, preventing an isolating switch or a handcart contact from being switched off and on under load, preventing a grounding wire (grounding switch) from being electrified, preventing a grounding switch (grounding wire) from being electrified and preventing the circuit breaker from being mistakenly switched into an electrified interval. The misoperation prevention of the transformer substation is usually realized by a microcomputer five-prevention system, and the five-prevention system greatly ensures the operation safety of the transformer substation, but has certain defects: computer keys, special coded locks, five-prevention machines and other equipment need to be installed, so that the types and the number of the equipment of the transformer substation are increased; the remote control operation of the monitoring system needs to be confirmed by communication with the five-prevention system, so that the operation time is increased; there are "lost motion" situations.

The transformer substation internal error prevention is composed of three layers of error prevention locking functions of a station control layer, a spacer layer and a process layer, and multi-level and comprehensive error prevention locking is provided for transformer substation operation. The station control layer is prevented mistake, the distance layer is prevented mistake and the process layer is prevented mistake and is independent, and mutual complementation, the function of preventing mistake that does not influence other layers when each layer prevents mistake function failure, ensures the operation safety of transformer substation.

In present transformer substation uses, extensively adopt the monitoring type to prevent mistake shutting system, this system includes the mistake prevention system of three-layer: the station control layer is used for preventing misoperation, the spacing layer is used for preventing misoperation and the electric unit is locked, the station control layer is mainly composed of a five-prevention workstation, a communication controller or a monitoring background, the spacing layer is mainly used for preventing operation by a microcomputer type measurement and control device, and the unit electric locking is realized by various locks. Although the microcomputer anti-misoperation system has achieved a great effect on preventing misoperation after years of construction and popularization, the microcomputer anti-misoperation system has the following problems:

in the engineering implementation process of building the substation anti-misoperation system, anti-misoperation rules of substation equipment under different operation modes need to be planned in advance, and the work is usually completed by professional technicians (electrical designers, technicians of five-prevention factories, experienced operators of substations or special five-prevention workers). When the transformer substation is large in scale, a large number of operating devices are used, and the operation mode is complex, the establishment of the anti-misoperation rule base of the transformer substation is time-consuming, labor-consuming and difficult to complete, and if negligence or errors exist in the established rule base, the anti-misoperation rule base is difficult to check, so that the five-prevention rule needs to be audited by experienced operators or full-time functions of the five-prevention, and the writing of the five-prevention rule is correct. The compiled rules need to be converted into an expression mode which can be read by anti-misoperation equipment, technicians of plant manufacturers of the station control layer anti-misoperation equipment and the bay layer anti-misoperation equipment respectively enter a monitoring background of the transformer substation and a microcomputer type measurement and control device, so that not only can a small amount of workload be brought, but also when the plant manufacturers of the station control layer anti-misoperation equipment and the bay layer anti-misoperation equipment are not the same equipment manufacturer, for the same rule, the expression mode of each equipment needs to be converted into, the workload can be larger, and the situation of inconsistency is likely to occur, so that the five-prevention rule entry is also one of easy-to-mistake.

The station control layer error prevention device and the spacer layer device do not have a regular comparison mechanism, and whether the locking rules in the station control layer device and the spacer layer device are consistent or not cannot be verified. In the debugging stage of the transformer substation equipment, omission of five-prevention locking rule input is easily generated, an effective comparison method is not available, and only the mode of re-input and coverage can be used. The station control layer, the spacing layer and the process layer are prevented from being mistakenly operated and lack a unified configuration tool, so that the automation degree is low, and the workload is increased.

In addition, for many anti-misoperation systems in China at present, a user inevitably generates many misoperation events when using the system for the first time, and in order to master the use of the system, the user often needs to refer to a user manual to do a large amount of operation exercises so as to master the system. The anti-misoperation system also needs to be configurable in a certain degree of increase and decrease of the operation flow according to actual conditions, otherwise, the operation flow also has the problem of use for operators.

Therefore, a new technical solution is needed to solve the above problems.

1. the station control layer anti-misoperation lockout rule comprises the refence of the related equipment, the index number of the database, the logic expression, the logic budget symbol, the equipment number and the equipment name description.

2. A spacer layer profile template is prepared.

3. And filling a device information description format (if the short address mode is adopted, short address information recorded by the station control layer device needs to be established first) into the relational database, wherein the format can be generated by using the information combination contained in the station control layer rule.

4. The logical symbols used in the spacer layer configuration file correspond to conventional symbols (e.g.,: ═ |, &, |, >, < etc.). The logical expression format comprises the combination mode of equipment items and logical symbols.

5. And the goose receiving points in the interval are used for carrying out format conversion when other interval equipment is found when the equipment information corresponding to the goose receiving information in the cross-interval logic is downloaded and the interval rule configuration file is downloaded.
