Detailed Description
The technical scheme of the invention is explained in detail in the following with the accompanying drawings:
the method coordinates three anti-misoperation systems of the OMS, the OCS and the SAS, comprehensively considers the anti-misoperation of the OMS, the safety check of the power grid of the OCS and the five-prevention check of the station control layer of the substation end of the SAS, and enables the coordinated safety anti-misoperation to run through the whole one-key programmed remote operation process.
The OMS system calls and reads the SAS system programmed operation ticket as a typical ticket library through the OCS system, and the OMS system directly issues the operation ticket (comprehensive order) to the SAS system through a transmission channel of the OCS system. The OMS system is responsible for controlling the operation process, the OCS system is responsible for transmitting the channel, and the SAS system is responsible for executing the request.
Specifically, the OMS system is responsible for the functions of generating and processing operation tickets, issuing operation tickets (comprehensive orders), filing, inquiring and the like; the OCS system provides error-proof check and safety check for the OMS system, serves as a transmission channel of the OMS system and the SAS system, receives the comprehensive order sent by the OMS system, orders the SAS system, returns the result to the OMS system, and meanwhile performs filing processing in the OCS system; the SAS system executes the OMS system which is forwarded through the OCS system to issue the operation command, and can also actively send the typical ticket library to the OMS system according to the change condition of the typical comprehensive command library of the OMS system, and the OMS system updates the typical ticket library of the OMS system.
As shown in fig. 1, a one-button programmed remote operation method based on network-side collaborative security anti-error check includes the following steps:
s1: and the master station OMS system generates a scheduling operation ticket, and performs error-proof check and related processes of the OMS system from the associated maintenance order and the simulated operation ticket through offline rehearsal, auditing, online rehearsal and the like, and mainly comprises model check, associated maintenance order error prevention, offline rehearsal error-proof check, online rehearsal error-proof check and the like.
And (3) model checking: the power grid model exchanges data among systems, and the model needs to be verified by adopting a comparison rule to ensure the correctness of the model data. And the OCS system exports model statistical information when exporting the model, and the OMS system counts the model data imported into the OMS system after completing model analysis and checks the model data with the statistical information of the OCS system so as to check whether the model is imported correctly.
And (4) preventing error of an associated maintenance list: and (4) generating a scheduling operation ticket by associating the maintenance order, taking the equipment operation target state of the maintenance order as a constraint condition by the system, checking whether the instruction of the operation ticket is consistent with the maintenance work requirement, and if the instruction of the operation ticket is inconsistent with the maintenance work requirement, giving an anti-error prompt by the system.
Offline preview error-proof inspection: as shown in fig. 2, after the instruction ticket graph is scheduled to be invoiced and the simulated rehearsal application is called, the system automatically performs simulated rehearsal based on offline data, analyzes operation contents one by one, and reminds and warns automatically through voice and characters if an error operation is detected through voice and corresponding animation display operation processes and error check.
If the simulated preview process has misoperation of violating strict locking such as basic five-prevention, the simulated preview is automatically terminated in the step, the simulated preview automatically generates a preview result, and the result clearly shows whether the preview of the operation ticket passes or not, and details of error-prevention reminding and warning.
The result of the simulated preview of the scheduling instruction ticket is stored in an overlaying mode, namely the operation ticket can be previewed for multiple times, and the system only keeps the preview result of the last time.
The system carries out graphic simulation preview operation on the generated operation ticket, and gives information such as power failure range and the like, so that a dispatcher can more visually audit a dispatching command, the problem that the dispatcher operates by means of memory is solved, and the operation ticket auditing process is more visual and visual. By graphically simulating preview audit, the audit of the operation ticket is improved from a manual experience analysis type to an automatic intelligent type, and the safety and the reliability of the operation are improved.
Online preview error-proof inspection: the online rehearsal is that before the sequence control operation sequence is executed, the system combines a five-prevention rule to realize the topological anti-misoperation locking among the devices, and the anti-misoperation locking among the devices is processed from the perspective of the whole network. In addition to the equipment state quantity error prevention, the topology error prevention device also has a hang tag (maintenance tag, isolation tag, power protection tag and the like) logic error prevention and a secondary error (air pressure, line disconnection, line protection switching and the like) error prevention.
As shown in fig. 3, after the simulated rehearsal is started in the flow process of the scheduling instruction ticket, the system automatically performs the simulated rehearsal based on the real-time operation data, analyzes the operation contents one by one, shows the operation process through voice and corresponding animation, and automatically reminds and warns through voice and characters if the error check detection is performed by the error check.
If the simulated preview process has misoperation of strict locking such as violation of basic five prevention, the simulated preview automatically ends at the step. The simulation rehearsal automatically generates a rehearsal result, and the result clearly shows whether the operation ticket passes the rehearsal or not, and details of error-prevention reminding and warning.
The result of the simulated preview of the scheduling instruction ticket is stored in an overlaying mode, namely the operation ticket can be previewed for multiple times, and the system only keeps the preview result of the last time.
And if the error checking is passed, the OMS system issues an operation instruction to the OCS system, and executes the step S2, otherwise, the program is terminated.
S2: and the master station calls a safety anti-misoperation function of the OCS system to perform safety verification before operating the equipment. Specifically, the OCS executes an operation instruction issued by the OMS, performs operation ticket checking, and calls a self security check function to perform error check, wherein the error check mainly comprises first state check and security check, and the security check comprises topology check and tide check.
The first state check is as follows: and verifying the preparation state of the equipment associated with the operation steps before the operation ticket steps are executed, giving a verification result, and interrupting the operation and giving a prompt when the states are inconsistent.
The topology verification has a full-network topology safety anti-misoperation function, and five-prevention locking of equipment operation is realized according to the topological relation between the electric island state and the electric equipment, namely the power grid topology and the five-prevention rule are combined to realize operation locking between the equipment. The method does not depend on manual definition, has good universality and maintenance-free performance, can accurately identify the anti-misoperation locking relationship between stations and in stations, and realizes the anti-misoperation locking from a whole network model. The topology verification comprises system topology anti-error verification and substation topology anti-error verification.
Specifically, system topology error prevention is primarily for remote operation of switches (circuit breakers), disconnectors, and grounding switches. The system topology anti-misoperation lockout does not depend on manual definition, and the safe operation of an operator is restrained by analyzing the running state of equipment through network topology; has the function of locking the hanging plate; the anti-mislocking function includes a prompt function, such as a ground switch with indication, a knife switch with indication, a charged knife switch with indication, a non-equipotential knife switch with indication, a knife switch operation sequence indication, a charged ground switch (ground switch) with indication, and a ground switch (ground switch) with indication. The system topology anti-misoperation can automatically perform comprehensive anti-misoperation check on the operation of an operator according to the topological relation of the power grid, the user-defined rule and the real-time remote signaling and remote measuring information of the steady-state data monitoring application.
And the substation topology anti-error check is used for executing the anti-error check of the substation. When the topology anti-error check is carried out, the system defaults to check based on the whole network topology, at the moment, the operation of the equipment has operation locking relation with the equipment of the local station and also has operation locking relation with the equipment of other plant stations, but when the system information is incomplete, the wrong check result can be caused.
The same-system topology anti-error is different in anti-error check based on the whole network topology, the substation topology anti-error check only carries out topology analysis on the equipment of the substation, and the anti-error check is carried out based on the electric island state and the equipment connection relation of the substation. The anti-error rule adopted by the transformer substation topology anti-error check is the same as the system topology anti-error rule, and the difference is the search boundary of topology analysis. In the power system, stations are communicated through lines, so that the anti-misoperation search boundary of the substation topology is the line, namely the line is searched and stopped, and thus, the stations and station equipment have no communication relation and no operation locking relation.
The flow verification is OCS flow safety verification of a network level and is used for verifying the current operation power grid flow distribution condition and checking whether branch flow out-of-limit or node voltage out-of-limit condition exists. In the process of scheduling operation by a dispatcher, the dispatcher often needs to perform quantitative analysis on the current operation, namely how the current operation affects the power flow of the power grid, whether the system can normally run, and the like. The system provides a power flow checking function, performs power flow calculation in real time according to current operation in the process of flow operation, and simultaneously checks voltage out-of-limit, line or main transformer overload and the like according to the power flow calculation result. The tide checking result mainly comprises the following steps: the load flow calculation convergence has no out-of-limit, the load flow calculation convergence has out-of-limit, the load flow calculation does not converge and the load flow calculation does not respond. When the load flow calculation is successful and has an out-of-limit, the system display information comprises: the out-of-limit branch name, the out-of-limit value, the out-of-limit calculated value and the out-of-limit branch out-of-limit ratio. If the checking is unsuccessful, the out-of-limit branch and the out-of-limit ratio are prompted to the user, and a quantitative auxiliary means is provided for accurate and safe scheduling of the dispatcher.
And if the first state check and the security check are passed, the OCS forwards the operation instruction issued by the OMS to the SAS system, and executes the step S3, otherwise, the program is terminated.
S3: the main website calls the programming control function of the SAS system of transformer substation to carry out remote operation, and the SAS system carries out operation ticket reading, operation ticket rehearsal and operation ticket execution in-process call station prevent mistake system and prevent mistake inspection, specifically include: the operation order executed by the SAS system is based on a sequence control operation typical order library verified by a station end; when the operation ticket is previewed, each step must pass the five-prevention check of the station control layer; when the operation ticket is executed, the operation ticket is subjected to station control layer five-prevention verification and spacing layer interlocking verification; the source state discrimination is carried out in the processes of ticket adjustment, preview and execution, and the corresponding flow can be started only when the source state is satisfied; a timeout determination mechanism is provided.
If the error check is passed, step S4 is executed, otherwise, the process is terminated.
S4: the OCS system performs a second state check that includes a telemetry information check and a telemetry location check.
Specifically, when the execution of the operation order step is completed, the operation step association is verified for the equipment target completion state, a verification result is given, and when the states are inconsistent, the operation is interrupted and a prompt is given.
And if the operation is finished through the second state check, the operation is considered to be finished, otherwise, the program is terminated.
In the method, the synergistic effect of the network end safety error-proof check is embodied as follows:
the safety error prevention of the master station system is error prevention safety inspection by using a full power grid, and mainly comprises topology error prevention and power flow check, wherein the specific inspection contents comprise error separation prevention and error switch closing prevention; the isolation switch is prevented from being pulled and closed under load; preventing the charged hanging (closing) of a grounding wire (grounding knife switch); preventing the switch (isolating knife switch) from being switched on with a grounding wire (grounding knife switch); checking the ring closing and ring opening parallel operation; pressure loss prevention, and the like. Compared with a substation anti-error system, the substation anti-error system is higher in anti-error level, wider in range and more in functions, and is mainly used for scheduling safety inspection before remote control instructions are issued and performing anti-error inspection of each link.
Substation anti-misoperation function mainly refers to traditional five-prevention function, specifically includes: the circuit breaker is prevented from being opened and closed by mistake; the isolating switch is prevented from being switched on and off under load; preventing the charged hanging (closing) of a grounding wire (grounding knife switch); the circuit breaker (isolating switch) is prevented from being closed by a grounding wire (grounding knife switch); prevent the wrong entering into the electrified interval. The substation anti-misoperation system has the characteristics of stability and reliability, has the defect of small anti-misoperation range, can not realize the equipment locking on the inter-substation connecting line only by the logic judgment of the substation, and is mainly applied to the local remote control operation of the substation.
The anti-misoperation system on the network side of the main station and the anti-misoperation system on the substation side of the transformer substation are responsible for safe operation, driving and protecting navigation of the power grid from different aspects and different levels, and the two systems cannot be used.
The method integrates the topology check and the trend check of the network end, the equipment state check of the plant end, the conventional five-prevention check and the like to form an integrated safety error-prevention check system which comprehensively considers the network end cooperation, forms an integrated remote operation flow, mechanism and error-prevention management system of the main station and the sub station, and avoids the occurrence of various error scheduling, error remote control and error operation.
In conclusion, the method fully utilizes the advantages of the network of the dispatching end, realizes integral safety check and error prevention control in the regulation and control range, provides corresponding service for the master station by the transformer substation error prevention system, and realizes the five-prevention check of the dispatching remote control command in the transformer substation. Through intelligent operation ticket management, flow control, safety check and linkage of the main station and the sub station, an anti-error management system integrated with the main station and the sub station is formed, the intelligent level in a regulation and control integrated mode is improved, and dispatching and monitoring operations are safer and more efficient.
