Detailed Description
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 in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The one-key sequential control system comprises a monitoring host, a communication gateway machine, a protection and measurement and control device, a sequential control host, an intelligent anti-misoperation host, a transport detection gateway machine, a disconnecting link state acquisition device, an idle switch control device, a pressing plate state acquisition device and a ground wire state acquisition device.
The monitoring host is located in a transformer substation II area, and soft pressing plate state and switching value information of the II area are obtained. The monitoring host is sent after collecting information sent by the receiving disconnecting link state collecting device, the air switch control device, the pressing plate state collecting device and the ground wire state collecting device through messages is collected through the communication network machine, the protection measuring and control device is connected with the relay protection device, and collected current information and the like are sent to the monitoring host after being collected through the communication network machine. And the monitoring host machine monitors the state.
The sequence control host is internally integrated with a billing system and a simulation rehearsal system; the billing system executes the billing task, simulates a rehearsal system to rehearse the operation task, and outputs error information if tripping occurs.
And the sequence control host receives the state information sent by the protection device through the communication gateway machine to generate a primary equipment diagram, wherein green represents normal connection, and red represents that failure exists when disconnection. An operator searches intervals (a switch and a breaker) of required operation according to a primary equipment diagram, clicks the intervals (the switch and the breaker), selects an interval state, generates an operation task, and sends the operation task to an invoicing system (integrated on a sequential control host) and an intelligent anti-error host. The sequence control host is internally provided with a history database which stores the state of each device received by the communication gateway machine and whether a fault exists. And setting an operation task corresponding to the task according to the state conversion of each interval, collecting the operation tasks and storing the operation tasks into a historical database, and directly searching the corresponding operation task according to the interval and the state to be converted when the operation task needs to be generated.
The intelligent anti-error host displays an operation interface of the sequence control host, and an auditor can check the primary equipment diagram and issue a sequence control termination or freezing sequence control operation instruction. And searching the operation at the same interval in the synchronous history library, if the operation sequence is completely consistent with the operation content, the operation is approved, the confirmation information is output to the sequence control host, and the invoicing system can execute the operation task content. The synchronous history library comprises data in a history database in the synchronous sequence control host, records of executed operation tasks and manually changed operation tasks.
After receiving the execution command, the sequence control host computer firstly carries out authority verification by the intelligent anti-error host computer and is divided into a system administrator, a system operator and a system auditor according to different functions, as shown in 1 and 2. The system administrator can delete and modify each user; the system operator is the executive role of the instruction, only has the authority of performing one-key sequential control operation, and cannot modify user and operation information; the system auditor can monitor the whole process of one-key sequence control, including auditing the authority of the operator and the operation content, if the auditing is not passed, the one-key sequence control process can be frozen, after the sequence control instruction is modified, the process can be thawed, and the one-key sequence control can be continuously executed.
The sequence control host with the one-key sequence control function is accessed to a station control layer network of the I area through dual-network redundancy, directly collects information such as the running state of primary and secondary equipment, a real-time electrical measurement value, power grid abnormity indication and the like from the station control layer network, and stores the information obtained for the first time into a database as a system initial state template. The key sequence control operation host computer is communicated with the original protection and measurement and control device through a station control layer network of the area I. The specific device connection situation is shown in the following figure:
after clicking a one-key sequence control button on a one-key sequence control interface, the intelligent anti-error host calls the running state (commissioning, hot standby, cold standby and overhaul) of each device from the sequence control host database and compares the running state with the system initial state template, if the running state is not matched with the device initial state template, an alarm is sent, and a system auditor decides to terminate sequence control operation or modify the device initial state template.
After the initial state correction is completed, the sequence control host searches the interval on the same bus with the operation equipment through the primary equipment table of the plant station, and generates an operation task according to the selected operation type (operation to hot standby, hot standby to overhaul and the like) and the interval matching result. After the operation task is generated, the operation task is compared with the similar operation task in the synchronous historical database, if the operation task is not in accordance with the synchronous historical database, an alarm is sent, the operation instruction marked with the difference is submitted to be audited by a system auditor, and the following selection can be made according to the actual situation after the audit:
1. operation error, not pass the audit: the sequence control process may optionally be terminated.
2. The operation is correct, the audit is passed, the history base is not updated: and storing the current operation ticket into a history library, and covering history information.
3. The operation is correct, the audit is passed, and the history library does not comprise the history information of the operation: and importing the new operation ticket into a history library.
And after the audit is passed, the sequence control host checks the operation condition, performs simulation rehearsal, and executes the operation task after the rehearsal is completed. In the operation process, the host interface is synchronized to the error-prevention host, and an auditor can monitor the sequence control process in the whole process and terminate the operation at any time.

(7) an auditor checks the condition before the project operation aiming at the operation project to be executed, judges whether the operation condition of the project is met, for example, whether the state of a breaker or a switch corresponding to the operation project is consistent with the state before the operation, if the operation project passes, the step (8) is carried out, otherwise, the sequence control operation is ended;
(8) the billing system executes the project;
(9) after the project is executed, an auditor checks conditions after the project operation aiming at the operation project to be executed, judges whether the corresponding breaker or switch state after the project execution is finished is consistent with the state after the operation, if so, the step (11) is carried out, and if not, the step (10) is carried out;
