In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The structural schematic diagram of the intelligent substation operation and maintenance system is shown in fig. 1 and comprises a monitoring host, an intelligent operation and maintenance anti-misoperation module, an intelligent substation operation and maintenance server and a substation operation and maintenance handheld terminal.
The monitoring host is provided with various equipment operation modules, such as a monitoring remote control module, an integrated five-prevention module, a sequential control operation module, a safety measure operation module and the like. The intelligent operation and maintenance anti-misoperation module is deployed in the intelligent substation monitoring system and belongs to the bottommost layer anti-misoperation locking mechanism.
The operation and maintenance method of the intelligent substation comprises the following steps:
(1) when primary or secondary equipment in the transformer substation needs to be operated, an operation request is sent to the intelligent operation and maintenance anti-misoperation module through the monitoring host.
Specifically, when the operation and maintenance personnel need to perform equipment operation, corresponding operation is selected at the monitoring host, and the relevant operation modules send operation requests to the intelligent operation and maintenance anti-misoperation module after acquiring operation tasks.
(2) The intelligent operation and maintenance anti-misoperation module receives an operation request sent by the monitoring host, and judges the locking logic of the primary or secondary equipment needing to be operated according to the operation request; if the lockout logic is satisfied, it is determined whether the operation type is a local operation or a remote operation.
Specifically, the intelligent operation and maintenance anti-misoperation module judges the locking logic of the primary or secondary equipment needing to be operated through a safety measure rule expert library, wherein the safety measure rule expert library comprises typical locking logic libraries and safety measure operation tickets of all operation objects of the station. The intelligent operation and maintenance anti-misoperation module judges the locking logic of an operation object by calling the locking rule and the operation sequence of corresponding equipment in the configuration library and combining the remote signaling and remote measuring real-time states of equipment in the station in the real-time library, and immediately locks when the logic is not satisfied.
In the process of making the safety measure rule expert base, the intelligent substation monitoring system firstly completes in-station equipment modeling according to engineering, establishes an overall anti-misoperation system based on the whole-station full-equipment information, brings all operable equipment such as primary equipment and secondary equipment in the intelligent substation into an intelligent operation and maintenance anti-misoperation module for calculation, and has active mandatory property, wherein the operable equipment cannot be executed when an unlocking command is not received or operation logic is not satisfied. A flow chart of the instantiated safety measure rule expert database formed by combining the expert database according to the in-station engineering configuration information is shown in fig. 2, and specifically includes the following steps:
1) generating an initial locking logic library and an safety measure operation order according to safety measure standards and specifications or according to a typical rule library and an engineering case;
2) the method comprises the steps that an initial locking logic library and safety measure operation tickets are combined with actual configuration in a transformer substation to automatically instantiate and generate the locking logic library and the safety measure operation tickets of the substation;
3) and the operation and maintenance expert audits and modifies the locking logic library and the safety measure operation ticket of the station according to actual requirements to generate a typical locking logic library and a safety measure operation ticket of the station.
In order to avoid misoperation, when the intelligent operation and maintenance anti-misoperation module judges that the locking logic of the primary or secondary equipment needing to be operated is not met, the operation is directly locked.
The operation equipment capable of acquiring the state and monitoring the communication can be remotely operated, and the operation instruction can be downloaded to the operation equipment by the monitoring system. For the operation object of which part of states can not be acquired and locking logic can not be downloaded, the operation instruction can not be directly downloaded to the operation equipment by the monitoring system, and remote control operation can not be carried out. The operation equipment which cannot be remotely operated is modified, the electronic chip is embedded in the operation equipment, the monitoring system sends an operation instruction to the transformer substation operation and maintenance handheld terminal, and the transformer substation operation and maintenance handheld terminal is used for matching and unlocking to realize on-site operation. The substation operation and maintenance handheld terminal incorporates all operable equipment in the intelligent substation, and the total station logic is configured uniformly.
(3) If the operation type is on-site operation, the intelligent operation and maintenance anti-misoperation module sends the operation instruction to the corresponding substation operation and maintenance handheld terminal.
In order to realize the communication connection between the intelligent operation and maintenance anti-misoperation module and the transformer substation operation and maintenance handheld terminal, an intelligent transformer substation operation and maintenance server is deployed in the area II, and a small wireless data network is established to realize the information interaction between the monitoring host and the transformer substation operation and maintenance handheld terminal. For the operation instruction of the on-site operation type, the intelligent operation and maintenance anti-misoperation module transmits the operation instruction to the intelligent substation operation and maintenance server, the intelligent substation operation and maintenance server issues the operation task to the substation operation and maintenance handheld terminal through the wireless data network, and the operator realizes the on-site operation through the substation operation and maintenance handheld terminal.
In addition, if the operation type is remote control operation, the intelligent operation and maintenance anti-misoperation module sends the command to the comm61850 module, the comm61850 communication platform sends the command to the primary or secondary equipment needing to be operated so as to realize the remote control operation, each step of operation receives the locking logic judgment of the intelligent operation and maintenance anti-misoperation module, if the locking logic is not met, the operation is locked, and the operation and maintenance operation flow of the soft pressing plate is given in fig. 3.
(4) The operation and maintenance personnel use the transformer substation operation and maintenance handheld terminal to realize the on-site operation of primary or secondary equipment in the transformer substation, each step of operation receives the locking logic judgment of the intelligent operation and maintenance anti-misoperation module, and if the locking logic is not satisfied, the operation is locked.
The transformer substation operation and maintenance handheld terminal obtains an operation task by interacting operation information with the monitoring host in real time. After browsing the operation order task and the currently executed operation object, matching the operation object with the handheld terminal, and successfully unlocking the operation object by the operation object matching, where fig. 4 shows an operation and maintenance operation flow of the hard pressing plate.
In addition, the transformer substation operation and maintenance handheld terminal can also send real-time alarm information in on-site operation to the monitoring host, can receive monitoring information in the transformer substation in real time and browse operation conditions in the substation. When the logic condition of the current operation object is not met due to the change of the position of equipment, the current operation is locked in time, other important signals in the station can be monitored, and the processing time of important information is shortened.
The following description is made in conjunction with a line 1SV receiving soft pressure plate of a 220kV bus protection device to describe mandatory measures for operation and maintenance operations of secondary equipment:
firstly, an intelligent substation monitoring system generates a line 1SV receiving soft pressing plate locking logic of a 220kV bus protection device and an safety measure operation ticket related to the 220kV bus protection device according to in-station modeling and an expert database.
The circuit 1SV of the 220kV bus protection device receives the soft pressing plate locking logic as follows: (line 1 interval circuit breaker position is 1) & (line 1 current value >0.1) & (protection service pressing plate is 0) & (MU service pressing plate is 0) & (intelligent terminal service pressing plate is 0), then the line 1SV receiving soft pressing plate which cannot exit the bus protection device.
When the operation and maintenance personnel do not have operation tasks, the operation in the station is forcibly locked by the intelligent operation and maintenance anti-misoperation module. When operation and maintenance personnel operate, sequence control operation is selected and executed, and each step of operation in the sequence control operation needs to be judged in real time through the intelligent operation and maintenance anti-misoperation module.
When the line 2 interval maintenance operation is executed, the line 1 normally runs at intervals, and the operation and maintenance personnel select an operation task to be the line 2 maintenance operation and execute the operation. If operation maintenance personnel operate to when the step of withdrawing from line 2SV receiving soft clamp plate, the wrong line 1SV receiving soft clamp plate is selected, the intelligent operation maintenance anti-misoperation module combines the state judgment of relevant equipment in the lockout logic library, and because the line 1 interval circuit breaker is closed and has current, and the bus protection device, the corresponding MU device and the intelligent terminal maintenance clamp plate all normally operate, the operation condition of withdrawing from the line 1SV receiving clamp plate is not provided, the operation is actively locked, the effective lockout of withdrawing from the bus protection operation interval SV receiving soft clamp plate misoperation is realized, and the bus protection misoperation caused by the operation condition is avoided.
