Detailed Description

In the related art, for a centralized control operation ticket, a centralized control station usually adopts a mode of issuing a command by a telephone or carrying a paper ticket by an executive person, so that the subordinate plant station can execute corresponding scheduling operation. However, if the telephone ordering method is adopted, communication may not be possible due to the influence of signal interference, and the transmission efficiency of the instruction information may be influenced by the factors such as the accent of the ordering personnel, so that the execution efficiency of the centralized control operation order is low. If the executive personnel carry the paper ticket to the subordinate plant station for execution, the labor cost for executing the centralized control operation ticket is increased, and the execution efficiency of the centralized control operation ticket is influenced.

In addition, when the subordinate plant station executes the scheduling operation according to the centralized control operation ticket, the execution result is fed back to the centralized control station in a telephone mode, and in the process, the problem that the feedback of the execution result is influenced by factors such as signal interference or voice of ordering personnel exists, so that the execution efficiency of the centralized control operation ticket is reduced.

Based on this, in various embodiments of the application, the first device acquires the centralized control operation ticket corresponding to the instruction ticket from the second device, and when acquiring the instruction for instructing issuing of the centralized control operation ticket, automatically issues the centralized control operation ticket to the substation, and timely sends execution information returned by the substation to the second device, so that the second device can update the execution result of the centralized control operation ticket based on the execution information. Therefore, the automation level in the execution process of the centralized control operation ticket can be improved, and the execution efficiency of the centralized control operation ticket is also improved.

An embodiment of the present application provides a communication method, which is applied to a first device, and as shown in fig. 1, the method includes:

step 101: sending an instruction ticket to the second device; the instruction ticket contains scheduling instructions for at least one substation;

step 102: acquiring a centralized control operation ticket corresponding to the instruction ticket from the second equipment, and sending the centralized control operation ticket to each transformer substation in at least one transformer substation when the first instruction sent by the second equipment is acquired; the centralized operation ticket contains at least one operation of each of the at least one substation; the first instruction is used for indicating that the centralized control operation ticket is issued to each transformer substation in the at least one transformer substation;

step 103: and acquiring operation execution information of each substation in at least one substation, and sending the acquired operation execution information to the second equipment.

In practical application, the first device may be called a scheduling command system (english may be expressed as a DCCS), and the DCCS performs steps 101 to 103.

In practical application, before step 101, a higher-level scheduling department (e.g., a scheduling master station) may determine an instruction ticket according to a maintenance plan or an operation task, and send the determined instruction ticket to the first device; wherein the instruction ticket contains scheduling instructions for at least one substation; the instruction ticket also contains identification information, such as numbering information.

Then, the first device sends an instruction ticket to the second device, so that the centralized control operation ticket corresponding to the instruction ticket is obtained from the second device.

Wherein the centralized operation ticket contains at least one operation of each of the at least one substation; the operation may include operation of a primary device, a secondary device, or the like; the primary devices may include devices for generating electricity in a substation, such as circuit breakers, transformers; the secondary equipment may include equipment in the substation for managing the primary equipment, such as protection devices, air pressure devices.

In actual use, in the process of determining the corresponding centralized operation ticket based on the instruction ticket, the second device may determine a plurality of centralized operation tickets (e.g., 5) based on the instruction ticket. In this case, the first device may acquire a plurality of centralized operation tickets corresponding to the instruction ticket by sending a request to the second device.

Based on this, in an embodiment, the acquiring, from the second device, the centralized control operation ticket corresponding to the instruction ticket includes:

In actual application, the first device may poll to send a full ticket information request to the second device to obtain each centralized control operation ticket of the at least two centralized control operation tickets corresponding to the instruction ticket. And when the first equipment does not receive the centralized control operation ticket corresponding to the full ticket information request sent by the second equipment, continuing polling to send the full ticket information request to obtain the centralized control operation ticket which is not received in the at least two centralized control operation tickets.

Illustratively, the first device may poll and send the full-ticket information request to the second device in the form of an XML file through an RPC protocol, so that the second device can provide the centralized control operation ticket corresponding to the full-ticket information request in the form of the XML file after receiving the full-ticket information request.

In this way, the first device can acquire a plurality of centralized control operation tickets corresponding to the instruction tickets from the second device.

In actual application, in step 102, after acquiring the centralized control operation ticket corresponding to the instruction ticket from the second device, the first device also acquires the first instruction sent by the second device. When the first instruction is obtained, the first device sends the centralized control operation ticket to each substation in at least one substation, so that each substation executes corresponding operation based on the centralized control operation ticket. For example, the first device may send the centralized control operation ticket to each of the at least one substation through the gateway, or may send the centralized control operation ticket to each of the at least one substation through the internal interface.

Here, when the first device acquires the first command transmitted by the second device, the first device may communicate with a child device of the second device to acquire the first command in order to secure data security on the second device side.

Based on this, in one embodiment, the second device includes a first sub-device and a second sub-device; the obtaining of the first instruction sent by the second device includes:

Here, the second device may include a first sub-device and a second sub-device; wherein the first sub-device is capable of communicating with the first device and the second sub-device is not capable of communicating with the first device; and the first sub-equipment and the second sub-equipment communicate with each other through a message bus inside the second equipment.

The second sub-device can send a first instruction to the first sub-device through a message bus, and then the first sub-device sends the first instruction to the first device; illustratively, the message bus may be implemented by an interface program provided by the second device. Therefore, the second sub-device can be prevented from being directly communicated with the first device, and the safety of data stored on the second sub-device side is guaranteed.

In the above process, the first device may receive, through the RPC protocol, the first instruction sent by the first child device, where the first instruction may be sent in the form of an XML file. The first device can obtain the first instruction by reading the XML file. The first device may then transmit the centralized operation ticket to each of the at least one substation to enable each substation to perform a respective operation based on the centralized operation ticket.

In practical application, after the corresponding transformer substation executes operation, the corresponding operation execution information is automatically fed back to the first equipment; the operation execution information may include relevant information such as execution result, execution time, execution personnel, and the like; the operation execution information is used for representing the execution condition of the centralized control operation ticket.

After the first device acquires the operation execution information of each transformer substation in at least one transformer substation, the acquired operation execution information is sent to the second device, so that the second device can update the execution result corresponding to the centralized control operation order.

In practical application, in order to ensure the security of the data stored on the second sub-device side, the first device may communicate with the sub-device of the second device to send the acquired operation execution information.

Based on this, in an embodiment, the second device includes a first sub-device and a second sub-device; the sending the acquired operation execution information to the second device includes:

Here, when the first device transmits the acquired operation execution information to the first sub-device, the acquired operation execution information may be transmitted in a manner of an RPC protocol.

Specifically, in an embodiment, the obtained operation execution information is sent to the first sub-device based on an RPC protocol, so that the first sub-device sends the received operation execution information to the second sub-device in an XML file, and the second sub-device stores the operation execution information.

In actual application, after the first device sends the acquired operation execution information to the first sub-device based on the RPC protocol, the first sub-device can send the operation execution information to the second sub-device in the form of an XML file through a message bus. The second sub-device can obtain the operation execution information by reading the received XML file, and store the operation execution information. Therefore, the second sub-device can be prevented from directly communicating with the first device, and the safety of the data stored on the second sub-device side is guaranteed.

Correspondingly, an embodiment of the present application further provides a communication method applied to a second device, as shown in fig. 2, the method includes:

step 201: receiving an instruction ticket sent by first equipment; the instruction ticket comprises a scheduling instruction of at least one substation;

step 202: determining a corresponding centralized control operation ticket based on the instruction ticket, and providing the centralized control operation ticket corresponding to the instruction ticket to the first device; the centralized operation ticket contains at least one operation of each of at least one substation;

step 203: when the centralized control operation order is determined to be executed, a first instruction is sent to the first equipment; the first instruction is used for indicating that the centralized control operation ticket is issued to each transformer substation in at least one transformer substation;

step 204: and receiving operation execution information corresponding to each substation in at least one substation sent by the first equipment, and updating an execution result corresponding to the centralized control operation ticket by using the received operation execution information.

In an actual application, the second device may be referred to as an EMS, and the EMS executes steps 201 to 204.

In actual application, after the second device receives the instruction ticket sent by the first device, a dispatcher of the second device can compile a centralized control operation ticket corresponding to the instruction ticket; for example, the dispatcher of the second device may determine the centralized control operation ticket corresponding to the instruction ticket based on the writing specification of the centralized control operation ticket; the centralized operation ticket contains at least one operation of each of at least one substation.

Wherein the operation may include operations of a primary device, a secondary device, and the like; the primary devices may include devices for generating electricity in a substation, such as circuit breakers, transformers; the secondary equipment may include equipment in the substation for managing the primary equipment, such as protection devices, air pressure devices.

Here, after the centralized control operation ticket corresponding to the instruction ticket is determined, an auditor may perform manual audit on the centralized control operation ticket, and after the audit is successful, the corresponding centralized control operation ticket is provided to the first device. If the auditing is failed, the auditor can modify the centralized control operation ticket and provide the modified centralized control operation ticket for the first equipment.

In practical application, since the dispatcher of the second device can determine a plurality of centralized control operation tickets based on the instruction ticket, in this case, the second device can respond to the request sent by the first device to provide a plurality of centralized control operation tickets corresponding to the instruction ticket.

Based on this, in an embodiment, the providing, to the first device, the centralized control operation instruction corresponding to the instruction ticket includes:

In actual application, after receiving a full ticket information request sent by polling of first equipment, if the centralized control operation ticket corresponding to the full ticket information request cannot be determined, the second equipment stops responding to the full ticket information request, and continues to receive the full ticket information request sent by polling of the first equipment until the centralized control operation ticket corresponding to the full ticket information can be determined, and responds to the full ticket information request.

Illustratively, the second device may receive full ticket request information that the first device polls for transmission in the form of an XML file via the RPC protocol. And after reading the XML file, the second equipment responds to the full ticket request information and provides the centralized control operation ticket corresponding to the full ticket request information to the first equipment in the form of the XML file.

In this way, the second device can provide a plurality of centralized control operation tickets corresponding to the instruction ticket to the first device.

In practical application, before step 203, the second device may further verify the operation of each substation in at least one substation included in the centralized control operation ticket, so as to ensure the rationality of the centralized control operation ticket. If the verification is successful, the second device can determine to execute the centralized control operation order; if the verification fails, the second device may prompt the dispatcher to modify the centralized control operation ticket and verify the modified centralized control operation ticket, until the modified centralized control operation ticket is successfully verified, the second device determines to execute the modified centralized control operation ticket.

Specifically, the second device may verify the centralized control operation ticket based on topology, device status, trend, and comprehensive error prevention; the topology is used for verifying the operation sequence of the conductive equipment; the equipment state is used for verifying the operation state of the equipment; the power flow is used for verifying the steady distribution of voltage and power; the comprehensive error prevention is used for checking a special scheduling rule.

And after the centralized control operation order is determined to be executed, the second equipment sends a first instruction to the first equipment. In order to guarantee data security on the second device side, the first device may communicate with the second device through the sub-device of the second device to send the first instruction to the first device.

Based on this, in one embodiment, the second device includes a first sub-device and a second sub-device; the sending a first instruction to the first device includes:

The second sub-device can send the first instruction to the first sub-device through a message bus, and the first sub-device sends the first instruction to the first device.

For example, after the second sub-device sends the first instruction to the first sub-device through the message bus, the first sub-device may generate an XML file based on the first instruction, and send the generated XML file to the first device through an RPC protocol, so that the first device may obtain the first instruction from the XML file, and then send the centralized control operation ticket to each of the at least one substation.

After each substation in at least one substation executes corresponding operation based on the centralized control operation ticket, the second equipment can receive operation execution information of each substation sent by the first equipment; the operation execution information can comprise execution result, execution time, execution personnel and other related information; the operation execution information is used for representing the execution condition of the centralized control operation ticket.

Specifically, in an embodiment, the first sub-device receives, based on an RPC protocol, operation execution information sent by the first device, sends the received operation execution information to the second sub-device in the form of an XML file, and the second sub-device stores the operation execution information.

Here, in practical application, the first sub-device may receive, based on the RPC protocol, operation execution information sent by the first device, and send the operation execution information to the second sub-device in the form of an XML file through a message bus, so that the second sub-device stores the operation execution information.

For example, the second sub-device may store the operation execution information in a local database, and the storage manner of the operation execution information is not limited in the embodiment of the present application.

Then, the second sub-device may update the execution result corresponding to the centralized control operation ticket by using the execution result, the execution time, the executive personnel and other information in the operation execution information, and display the execution result of the centralized control operation ticket through a display interface of the second sub-device, so that the dispatcher can obtain the execution condition of the substation in real time. In the process, the execution efficiency of the centralized control operation order is improved by optimizing the flow of executing the centralized control operation order.

The present application will be described in further detail with reference to the following application examples.

In the application embodiment of the application, aiming at the problems that the traditional centralized control operation order is low in execution efficiency and cannot meet the requirement of safe and stable operation of a power grid, the method for performing data interaction between the DCCS and the EMS is provided, the purpose of executing the centralized control operation order through programmed control can be achieved, and a dispatcher can complete a dispatching task safely and efficiently.

As shown in fig. 4, the process of the DCCS performing data interaction with the EMS includes the following steps:

step 401: DCCS receives an instruction ticket issued by a master dispatching station;

here, since the DCCS is a provincial-local integrated system, a dispatcher at a general dispatching station can write an instruction ticket in the DCCS according to a maintenance task or a temporary operation task; the instruction ticket contains a scheduling instruction of the master scheduling station to a subordinate plant station (namely a transformer substation).

After receiving the instruction ticket issued by the master dispatching station, the DCCS sends the instruction ticket to the EMS of the centralized control station.

Step 404: the EMS displays the centralized control operation ticket corresponding to the instruction ticket for the auditor to manually audit;

if the audit is passed, the EMS may update the status of the centralized control operation ticket to an execution stage to execute step 405; if the audit is not passed, the EMS can prompt the dispatcher so that the dispatcher can modify the centralized control operation order.

Step 405: the EMS transmits the centralized control operation order in the execution stage to the DCCS;

in actual application, when the instruction ticket corresponds to a plurality of centralized control operation tickets, the DCCS transmits a full ticket information request instruction to the EMS by polling through the RPC protocol, so as to obtain the centralized control operation ticket in the execution stage. After receiving a full ticket information request instruction transmitted by DCCS polling, the EMS responds to the full ticket information request instruction and transmits the centralized control operation ticket in the execution stage to the DCCS in the form of an XML file.

Step 406: the DCCS receives a centralized control operation order sent by the EMS;

step 407: the DCCS judges whether to execute a centralized control operation order;

here, when the dispatcher of the centralized control station determines to execute the centralized control operation ticket through the EMS, the EMS checks the centralized control operation ticket based on the topology, the device status, the trend, and the comprehensive error prevention. If the verification is passed, the EMS can update the step state of the centralized control operation order into a power transformation execution state, and simultaneously, an execution instruction is issued to the DCCS; if the verification fails, the EMS can prompt a dispatcher of the centralized control station so that the dispatcher can modify the current centralized control operation order.

In practical application, after receiving an execution instruction issued by the EMS, the DCCS checks the centralized control operation order again based on topology and error prevention. If the check passes, go to step 409; if the step corresponding to the centralized control operation ticket cannot be executed based on the field situation, the verification is failed, and the step 408 is executed;

step 408: interrupting and reminding;

in actual application, when the DCCS determines that the centralized control operation order cannot be executed, interrupting the current operation step and generating corresponding execution information; the execution information includes information such as execution result and failure reason.

Step 409: the DCCS issues a centralized control operation ticket to the subordinate plant station and acquires the execution information (namely operation execution information) of the subordinate plant station;

in actual application, after receiving an execution instruction issued by the EMS, the DCCS may send the centralized control operation ticket to the corresponding subordinate plant station, so that the subordinate plant station can execute corresponding operations based on the centralized control operation ticket, which may specifically include operations of the primary device and the secondary device. After the execution of the subordinate plant station is finished, the execution information is automatically returned to the DCCS, and the DCCS sends the execution information to the EMS; the execution information comprises information such as step states, field operators, field operation completion time and the like.

Specifically, as shown in fig. 5, after the subordinate plant station completes execution, the execution information is automatically returned to the DCCS, and the DCCS sends the execution information to an RPC server corresponding to the two-region EMS in an RPC service manner; the RPC server places the execution information in a specified folder directory in the form of an XML file, so that the two-region EMS can send the XML file in the directory to the one-region EMS through a message bus.

In addition, for the execution information corresponding to the centralized control operation ticket which cannot be executed, the DCCS also sends the execution information to an RPC server corresponding to the two-region EMS in an RPC service mode; the RPC server places the execution information in a specified folder directory in the form of an XML file, so that the two-region EMS can send the XML file in the directory to the one-region EMS through a message bus.

Step 410: the EMS updates and archives the centralized control operation ticket by using the received execution information;

here, in actual application, the EMS in one area may update the execution result of the centralized control operation ticket by using the execution information, and display the execution result of the centralized control operation ticket through a display interface of the EMS.

For example, as shown in fig. 6, the dispatcher can view the execution information of each subordinate station side corresponding to the centralized control operation order in real time based on a display interface of the EMS.

Then, the EMS of the first area sends the processing result of the centralized control operation order to the EMS of the second area through a message bus, so that the EMS of the second area can return the processing result to the DCCS in the form of an XML file through the RPC service.

In practical application, after all operations on the centralized control operation ticket are executed, the EMS can file the centralized control operation ticket, namely, the centralized control operation ticket is stored, so that later-stage checking and statistics are facilitated; and the centralized control operation ticket in the filing state cannot be modified.

Step 411: and ending the current operation flow.

In the application embodiment of the application, a method for interaction between EMS and DCCS is provided, and communication between EMS and DCCS is constructed in a mode of RPC and xml file service. After the centralized control station dispatcher formulates the centralized control operation order according to the content of the total dispatching instruction order, the executive information and the instruction order of the transformer substation end can be timely checked through the display interface of the EMS, so that the dispatcher can accurately master the field executive progress and executive condition of the transformer substation. Compared with the traditional execution mode of the centralized control operation order, the execution efficiency of the centralized control operation order can be improved, and the safety and the reliability of the operation of the power grid are further improved.
