Furthermore, in the first channel, an operator of the EMS master station checks the relay protection setting data to be configured, and in the second channel, the operator of the information protection master station checks the relay protection setting data to be configured, so that double data checking is realized, and the safety of the remote configuration relay protection setting process is fully ensured.
Fig. 3 shows a flowchart of a relay protection setting remote configuration method according to an embodiment of the present disclosure. With reference to fig. 3, the flow of performing relay protection fixed value secure remote configuration by checking the relay protection fixed value data doubly, independently performing authorization application and issuing the relay protection fixed value data in each channel in the embodiment of the present application is further described.
In a possible implementation manner, in step 20, the applying for authorization by the grid dispatching end through the first channel includes: the information protection master station sends the authorization application and the relay protection constant value data to an EMS master station; and if the relay protection setting value data passes the verification, the EMS master station sends an instruction for inputting a remote modification setting value soft pressing plate to the relay protection equipment through the remote machine.
Before the relay protection setting data is configured remotely, the information protection master station initiates an authorization application of remote relay protection setting operation configuration to the EMS master station, and simultaneously sends the relay protection setting data to be configured to the EMS master station, and in the EMS master station, an operator checks the relay protection setting data to be configured, including checking an operation object and the operation data; and after the verification is correct, sending an instruction of remotely modifying the constant-value soft pressing plate for putting into the target relay protection equipment to a telemechanical at the power grid plant station end through the EMS main station, and forwarding the instruction to the target relay protection equipment by the telemechanical.
Specifically, as shown in fig. 3, when an operator prepares to remotely configure relay protection setting data, the operator selects, at the information master station, a relay protection device prepared to configure relay protection setting at the power grid station end, and inputs the relay protection setting data to be configured; the relay protection customized data can comprise a target relay protection device name for preparing configuration setting values, one or more setting value items for preparing configuration and the like. The method comprises the steps that a guarantee master station sends the name of target relay protection equipment with a preset configuration value and one or more items of preset values (including the preset value name and specific values of the preset values) to an EMS master station through a network, meanwhile, an authorization application of remote relay protection setting value configuration operation is initiated to the EMS master station, after the EMS master station receives the authorization application and relay protection setting value data to be configured, an operator of the EMS master station audits the relay protection setting value data to be configured, namely the name of the target relay protection equipment with the preset value and one or more items of preset values (including the preset value name and the specific values of the preset values) are audited, if the audit is abnormal, the authorization application fails, the EMS master station sends an instruction that the authorization application fails to the guarantee master station, and the guarantee master station suspends the remote relay protection setting value configuration operation; and if the verification is passed, issuing a remote modification fixed value soft pressing plate instruction for inputting the target relay protection equipment by an operator of the EMS main station through a remote engine deployed in a power plant or a transformer substation where the target relay protection equipment is located by the EMS main station.
In a possible implementation manner, in step 20, the power grid dispatching end applies for authorization through a first channel, and further includes: responding to the instruction of inputting the remote modification constant value soft pressing plate by the relay protection equipment, inputting the remote modification constant value soft pressing plate, and sending an input result to an EMS master station through a telemechanical system; and if the input result is successful, the EMS master station sends an authorization application passing instruction to the information protection master station.
As shown in fig. 3, after receiving an instruction for inputting a remote modification constant value soft pressing plate issued by a remote motor, a target relay protection device at a power grid plant end executes an operation for inputting the remote modification constant value soft pressing plate, and sends a result of whether the input is successful to an EMS master station through the remote motor; specifically, if the input result is successful, the successful input result of the soft pressing plate is fed back to an EMS main station through a telecontrol machine, the EMS main station sends an authorization application passing instruction to a guarantee main station, and the guarantee main station executes the subsequent operation of issuing relay protection definite value data; and if the input result is failure, feeding back the result of the failure of the input of the soft pressing plate to an EMS main station through a telecontrol machine, sending an authorization application failure instruction to the security main station by the EMS main station, and suspending the operation of remotely configuring the relay protection setting value by the security main station. And at this moment, the operation of authorization application is completed through the first channel, and meanwhile, the relay protection fixed value data is checked in the operation.
In a possible implementation manner, in step 30, the issuing, by the power grid dispatching end, the relay protection setting data to the power grid plant end through the second channel includes: and if the relay protection setting value data passes the verification, the information protection main station issues the relay protection setting value data to the relay protection equipment through the information protection substation.
After receiving the instruction that the authorization application sent by the EMS master station passes, the information protection master station performs manual checking on the relay protection setting data to be configured, and if the checking passes, the information protection slave station issues the relay protection setting data to be configured to the target relay protection equipment. Specifically, as shown in fig. 3, an operator of the protection master station first checks the name of the target relay protection device to be configured with a fixed value, and one or more items of the fixed value to be configured (including the fixed value name and specific values of each fixed value), prevents an operation object from being wrong and issues wrong relay protection fixed value data, and after no error is confirmed, the protection master station sends the relay protection fixed value data to a protection slave station in a power plant or a transformer substation where the target relay protection device is located, and the protection slave station issues the relay protection fixed value data to the target relay protection device and issues a set value configuration instruction. Therefore, manual checking is carried out on the relay protection setting value data to be configured through an operator of the information-protecting main station and an operator of the EMS main station, so that double data checking is realized, manual misoperation or malicious operation is effectively avoided, and the safety of the remote configuration relay protection setting value process is fully ensured.
It should be noted that, the manual checking of the relay protection setting value data to be configured by the operator of the information-guaranteeing master station may be performed before the authorization application is sent to the EMS system (i.e., before step 20), or may be performed after the authorization application is sent and passed by the EMS system (i.e., after step 20), which is not limited in this embodiment.
In a possible implementation manner, in step 30, the power grid dispatching end issues the relay protection setting data to the power grid plant end through a second channel, and the method further includes: the relay protection equipment judges whether the remote modification fixed value soft pressing plate is in a switching state; and if the relay protection device is in the input state, configuring the relay protection constant value data in the relay protection device, and returning a constant value successful configuration result to the information protection main station through the information protection substation.
After receiving relay protection fixed value data sent by the information protection substation, target relay protection equipment at the power grid plant station responds to a fixed value configuration instruction, judges whether a remote modification fixed value soft pressing plate of the equipment is in a putting-in state or not, and further executes the next operation, specifically, as shown in fig. 3, if the target relay protection equipment judges that the remote modification fixed value soft pressing plate of the equipment is in the putting-in state, the target relay protection equipment executes a fixed value configuration instruction, downloads and solidifies the relay protection fixed value data to an operation area of the equipment, and feeds back a result of successful configuration of the fixed value to the information protection main station through the information protection substation; and if the target relay protection equipment judges that the remote modification constant value soft pressing plate of the equipment is not in the input state, refusing to execute constant value configuration, feeding back a result of failure of constant value configuration to the information protection main station through the information protection substation, and stopping remote configuration relay protection constant value operation after the information protection main station receives the result. Therefore, the operation of issuing the relay protection setting data is completed through the second channel, and meanwhile, the relay protection setting data is checked in the operation.
Therefore, the operation of independently executing authorization application and issuing relay protection setting value data through the first channel and the second channel is completed, and double checking of the relay protection setting value data is completed in the first channel and the second channel, so that relay protection setting value safety remote configuration is realized.
In one possible implementation, the method further includes: after receiving the fixed value successful configuration result, the information-protecting master station sends an authorization-removing application to the EMS master station; the EMS master station sends an instruction for quitting remotely modifying the constant-value soft pressing plate to the relay protection equipment through the remote machine; the relay protection equipment responds to the instruction for exiting the remote modification constant value soft pressing plate, exits the remote modification constant value soft pressing plate and sends an exiting result to the EMS master station through the telemechanical system; and if the quit result is successful, the EMS master station sends an authorization removal application success instruction to the information protection master station.
After the information master station receives the result of the successful configuration or the failure configuration of the fixed value fed back by the target relay equipment, the authorization application of the remote configuration relay protection fixed value at this time is released through the first channel; specifically, as shown in fig. 3, the information protection master station initiates an authorization release application to the EMS master station, the EMS master station sends an instruction to exit from the relay protection device to remotely modify the constant value soft pressing plate to the telemechanical device at the power grid plant station end, the telemechanical device forwards the instruction to the target relay protection device, the target relay protection device responds to the instruction to execute an operation of exiting from remotely modifying the constant value soft pressing plate, and feeds back a successful exit result of the soft pressing plate to the EMS master station through the telemechanical device, and the EMS master station sends an authorization release application success instruction to the information protection master station, so that the relay protection constant value remote configuration process is ended.

In fact, the user can flexibly set each implementation mode according to personal preference and/or actual application scene, as long as the technical scheme of the disclosure is met.
