As shown in fig. 2, the dispatching master station has master station anti-error logic, and the logic steps are as follows:
step S11, the dispatcher sends an operation instruction to the monitor, and the monitor starts a sequence control task;
step S12, the topology anti-misoperation safety check of the master station checks the correctness of the scheduling operation task;

The invention adopts the following innovative measures:
(1) and innovatively developing a master station functional module. The master station completes the capacity expansion of the front shared memory and the program upgrade and replacement of the front server, and after the station side upgrades the versions of the background library and the telecontrol library, the functions of authority management, task analysis, ticket face reading, error check prevention, simulation rehearsal, operation execution and the like are realized, and the master station and the station side background sequence control module are comprehensively communicated, as shown in fig. 4.
(2) And standardizing telecontrol communication protocols uniformly. Aiming at the problem that the station end background machine and the main station D5000 system belong to different manufacturer equipment, communication protocols are not matched with each other, and integrated cooperative operation of the main station and the sub station cannot be realized, technicians of various manufacturers are organized to jointly research and uniformly configure the updated third-generation IEC104 protocol, correct and smooth interaction of remote control instructions between the main station and the sub station is realized, and a communication barrier between the station end monitoring and the telecontrol machine is broken through at one stroke, as shown in FIG. 5.
(3) The information flow of the main and sub-stations is fully expanded. Compared with the conventional four-remote information, after the master station calls the station end to perform one-key sequential control, the information interaction quantity between the main station and the sub station is increased by geometric multiples, so that abnormal conditions such as operation clamping stagnation, slow speed and the like are prevented, the interface path between the main station and the sub station is comprehensively expanded, and the functions of ticket surface reading, error check prevention, simulation rehearsal, operation execution and the like are ensured to be safely, efficiently and smoothly developed.
The present invention differs from the prior art:
1. the master station and the station end system are interconnected, and the remote control operation division is more reasonable. The programmed remote control operation technology originally applied by the regulation and control center is completely and predominantly completed by a monitor in the whole operation process and each link from programming to starting execution, so that the situations that the command is wrongly issued and the risk of the misoperation is controlled by a large operation system are prevented, the operation steps are complicated, the risk potential is more, and the safety responsibility is great.
After the station end has the one-key sequential control function, the scheduling master station and the station end system are interconnected and run through a plurality of links by adopting the technical innovation, applying the modern information technologies such as network interconnection, data sharing, artificial intelligence and the like and the advanced communication technology, the calling function is deployed by the master station end after the master station calls the one-key sequential control technology of the station end, and the plant station background is responsible for safety check, execution and feedback. The system is the same as the traditional operation mode, a large operation system only bears the risk of controlling the wrong orders, a large maintenance system is responsible for controlling the wrong operation risk, the joint management and control and integrated operation of dispatching and operation inspection departments is realized, and the safety responsibility boundary among different systems is further defined.
2. The system has a perfect anti-error check function, and the remote control operation is safer to execute. The regulation of the Anrule: before the operation is started on site, the checking simulation preview should be carried out on the simulation diagram (or the microcomputer anti-error device and the microcomputer monitoring device), and after no error, the perfect anti-error operation locking device should be installed to operate the high-voltage electrical equipment. The anti-misoperation locking device cannot be randomly withdrawn from operation, and the anti-misoperation locking device is stopped to be approved by administrative and subsidiary staff or general engineers in the branch management production of the unit; when the anti-misoperation locking device is quitted in a short time, the anti-misoperation locking device is approved by a substation manager or a power plant on-duty manager and is put into operation as soon as possible according to a program. Therefore, simulating preview and preventing misoperation locking are two indispensable technologies. However, the two technologies of programmed remote control operation originally applied by the control center cannot completely meet the requirements, and the problems of unstable operation, unreliable locking and the like exist.
The master station calls a station end one-key sequence control technology, and has the functions of perfect authority management, operation task editing and analyzing, topology error prevention, operation ticket reading, simulation rehearsal, operation execution and the like. And two sequential control modes of step-by-step control and comprehensive control are supported, and the step rehearsal result sent by the substation end and the total operation order rehearsal result can be displayed step by step. Before operation, the topology anti-error check and the monitoring alarm information check are carried out, and the check can be carried out by sequence control operation at the rear part. The method has strict process control, and can automatically lock the next operation process when the current process is not finished or passes; each link in the operation process can verify key information, including information such as operation objects and operation steps, and when the scheduling command information is found to be inconsistent with the feedback information of the transformer substation end, the operation can be immediately terminated and actively prompted, as shown in fig. 6.
3. And a station-end programmed control sequence is called, and the remote control operation is carried out more quickly. The programmed remote control operation technology originally applied to the regulation and control center needs manual compilation by a monitor, wastes time and labor, is easy to cause errors, and buries potential safety hazards for misoperation.
When the master station calls the station end one-key sequence control technology, the operation can be completed by remotely calling the station end sequence control operation order according to the scheduling comprehensive operation order, and the data acquisition and exchange server has the function of receiving the substation end sequence control operation order and can temporarily store the operation order for subsequent operation processing. Checking the content of the called operation tickets, sequentially controlling the content format of the operation tickets to meet the requirements of regulations, and correctly displaying the operation tickets sent by the substation side, wherein the content comprises operation objects, operation steps and the like; when the operation ticket of the substation end is unsuccessfully retrieved, the error reason of uploading can be correctly analyzed, and active prompt is given. After the operation ticket is successfully retrieved, a simulated preview instruction can be manually sent. And the operation order is controlled by calling the station end sequence, so that a manual writing link is saved, and the remote control operation is quicker, as shown in figure 7.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; it is obvious as a person skilled in the art to combine several aspects of the invention. And such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
