Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, specific embodiments of the transformer substation mis-locking prevention method and device of the present invention are described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
referring to fig. 1, in one embodiment, a method for preventing a transformer substation from being locked by mistake includes the following steps:
and S100, configuring an anti-misoperation locking logic judgment mode.
The error-proof locking logic judgment mode can comprise an error-proof host request mode and a real-time error-proof logic calculation mode without an error-proof host. It can be understood that the anti-misoperation host request mode is to perform unlocking operation and locking operation on the locked device according to the unlocking request and the locking request sent by the anti-misoperation host. The real-time anti-misoperation logic calculation mode of the non-anti-misoperation host sends an unlocking request or a locking request to the non-anti-misoperation host, and the locked equipment is subjected to unlocking operation and locking operation according to the state information and the locking logic of each equipment in the transformer substation.
S200, if the anti-misoperation locking logic judgment mode is the anti-misoperation host request mode, processing an unlocking request of the anti-misoperation host according to the locking logic of the locked equipment, and sending a first processing result to the corresponding measurement and control device and/or intelligent terminal; and directly sending the locking request of the anti-misoperation host to the corresponding measurement and control device and/or intelligent terminal.
The method for processing the unlocking request of the anti-misoperation host according to the locking logic of the locked device may be: if the unlocking operation corresponding to the unlocking request of the anti-misoperation host is legal operation relative to the locking logic of the locked equipment, the first processing result is the unlocking operation; otherwise, the first processing result is null. And after the corresponding measurement and control device and the intelligent terminal receive the first processing result, executing corresponding operation according to the first processing result. It can be understood that when the first processing result is empty, the corresponding measurement and control device and the intelligent terminal do not execute operation, or the first processing result does not occur to the corresponding measurement and control device and the intelligent terminal.
and after the corresponding measurement and control device and the intelligent terminal receive the locking request, executing corresponding locking operation according to the locking request.
and S300, if the anti-misoperation locking logic judgment mode is the real-time anti-misoperation logic calculation mode without the anti-misoperation host, receiving the equipment state information of the equipment in the station, performing unlocking processing on the locked equipment according to the equipment state information of the equipment in the station and the locking logic of the locked equipment, and sending a second processing result to the corresponding measurement and control device and/or the intelligent terminal.
The unlocking and locking signal of the locked device can be calculated according to the locking logic of the locked device and the device state information of the in-station device, and the calculation result is sent to the measurement and control device and/or the intelligent terminal. And the measurement and control device and/or the intelligent terminal execute corresponding operation according to the received calculation result.
The calculation result may be an unlock signal or a lock signal. And after receiving the unlocking signal or the locking signal, the measurement and control device executes corresponding operation according to the unlocking signal or the locking signal. Similarly, after receiving the unlocking signal or the locking signal, the intelligent terminal executes corresponding operation according to the unlocking signal or the locking signal. For example, the intelligent terminal unlocks according to the unlocking signal, and after the intelligent terminal is remotely controlled, the intelligent terminal locks according to the locking signal.
In addition, a VSG (visual String Setting) data type can be extended under the CILO logical node, and the latching logic of the latched device can be edited by the VSG data type. Wherein CILO is an interlocking logic node, and the VSG data type is an editing model of the latching logic. The editing model may be configured to support a fixed-value service, enabling a configuration client to edit lockout logic online in a fixed-value manner. Of course, the editing model may be configured to support a set-point service, enabling a configuration client to edit the lockout logic online in a set-point manner.
according to the transformer substation anti-misoperation locking method, aiming at different anti-misoperation locking logic judgment modes, the unlocking logic of the locked equipment is processed according to the equipment state information of the equipment in the substation and the locking logic of the locked equipment, and the corresponding unlocking or locking processing result is sent to the corresponding measurement and control device and/or intelligent terminal, so that the prevention of electrical misoperation of the measurement and control device and the process intelligent terminal on the spacer layer of the digital transformer substation and the intelligent transformer substation can be realized, and the guarantee is provided for the safe operation of the transformer substation.
based on the unified invention concept, the embodiment of the invention also provides a transformer substation anti-misoperation locking device. Because the principle of solving the problems of the device is similar to that of the transformer substation anti-misoperation locking method, the implementation of the device can be realized according to the specific steps of the method, and repeated parts are not repeated.
Referring to fig. 2, in one embodiment, the substation anti-misoperation lockout device includes a model configuration unit 100, an information acquisition unit 200, a lockout logic calculation unit 300, and a transmission unit 400.
The model configuration unit 100 is configured to configure a first model of the in-station device. The model configuration unit 100 is further configured to configure a second model of the mislatching prevention logic determination mode. The model configuration unit 100 is also used to configure a third model of the locking device.
The information obtaining unit 200 is configured to receive the device state information of the devices in the station according to the first model configured by the model configuration unit 100. The information obtaining unit 200 is further configured to receive an anti-false-locking logic determination mode of the configured client according to the second model. The information obtaining unit 200 is further configured to receive a request for configuring locking logic of the client and unlocking of the anti-error host according to a third model. The information obtaining unit 200 sends the device state information of the in-station device and the unlocking request of the anti-misoperation host to the locking logic calculation unit 300. And, the information acquisition unit 200 transmits the lock logic to the lock logic management unit 500.
The latching logic management unit 500 is configured to analyze, judge and store the latching logic, and send the latching logic to the latching logic calculation unit 300.
And the locking logic calculation unit 300 is configured to process a locking logic of the locked device, and send a corresponding unlocking or locking processing result to the corresponding measurement and control device and/or intelligent terminal through the sending unit 400. The measurement and control device is a measurement and control device of a substation control layer of the transformer substation. The intelligent terminal is an intelligent terminal of a transformer substation process layer.
The specific process of the latching logic management unit 500 for performing validity judgment and storage on the latching logic may be as follows: if the latching logic management unit 500 determines that the latching logic is valid, the latching logic is stored; if the lockout logic management unit 500 determines that the lockout logic is not valid, the lockout logic is not stored.
In one embodiment, the device status information of the in-station device may be device status information corresponding to the anti-error logic of the locked device. For example, the device state information of the in-station device may be an operating parameter, an operating time, and the like of the in-station device. The equipment state information of the equipment in the station can be acquired through the intelligent terminal. For example, the information obtaining unit 200 may send a request for device state information of the in-station device to the intelligent terminal, and then the intelligent terminal sends the collected information to the information obtaining unit 200. The information obtaining unit 200 may also obtain the device state information of the in-station device collected by the intelligent terminal in real time.
As an implementation manner, the second model configured by the model configuration unit 100 may be configured as an anti-error host request mode, and may also be configured as a real-time anti-error logic calculation mode without an anti-error host. When the second model is configured to be in the real-time anti-error logic calculation mode, the latching logic calculation unit 300 performs the unlatching process of the latched device according to the device state information of the in-station device and the latching logic of the latched device, and sends the corresponding second processing result to the corresponding measurement and control device and/or intelligent terminal.
The result of the latch releasing process performed by the latch logic calculating unit 300 is the second processing result. And the second processing result may be an unlock signal or a lock signal. After receiving the unlocking signal or the locking signal sent by the sending unit 500, the measurement and control device executes corresponding operations according to the unlocking signal or the locking signal. Similarly, after receiving the unlock signal or the lock signal sent by the sending unit 400, the intelligent terminal executes a corresponding operation according to the unlock signal or the lock signal. For example, the intelligent terminal unlocks according to the unlocking signal, and after the intelligent terminal is remotely controlled, the intelligent terminal locks according to the locking signal.
In one embodiment, when the second model configured by the model configuration unit 100 is configured as the anti-misoperation host request mode, the information obtaining unit 200 is further configured to receive an unlocking request and a locking request of the anti-misoperation host, and send the unlocking request and the locking request of the anti-misoperation host to the locking logic calculation unit 300.
when receiving the unlocking request of the anti-misoperation host, the locking logic calculation unit 300 judges whether the unlocking request of the anti-misoperation host is legal or not according to the locking logic and the device state information of the in-station devices. If the unlocking request of the anti-misoperation host is legal, the unlocking operation corresponding to the unlocking request of the anti-misoperation host is sent to the measurement and control device and/or the intelligent terminal through the sending unit 400. Otherwise, the unlocking operation corresponding to the unlocking request of the error-proof host is not sent to the measurement and control device or the intelligent terminal. When receiving the locking request of the anti-misoperation host, the locking logic calculation unit 300 directly sends the locking request of the anti-misoperation host to the measurement and control device and/or the intelligent terminal through the sending unit 400.
When the locking logic calculation unit 300 receives a locking request of the anti-misoperation host, the corresponding locking operation is sent to the measurement and control device and/or the intelligent terminal through the sending unit 400.
after receiving the unlocking request or the locking request sent by the sending unit 400, the measurement and control device executes corresponding operations according to the unlocking request or the locking request. Similarly, after receiving the unlocking request or the locking request sent by the sending unit 400, the intelligent terminal executes a corresponding operation according to the unlocking request or the locking request.
When the second model configured by the model configuration unit 100 is configured as a real-time anti-error logic calculation mode without an anti-error host, the latching logic calculation unit 300 calculates an unlatching signal of the latched device according to the latching logic and the device state information of the devices in the station, and sends the calculation result to the measurement and control device and/or the intelligent terminal through the sending unit 400.
Preferably, the latching logic managing unit 500 is further configured to edit the latching logic online and send the edited latching logic to the latching logic calculating unit 300. The online editing method is to extend a VSG data type under the CILO logic node, so that the configuration client can perform online editing on the latching logic through the VSG data type. Wherein CILO is an interlocking logic node, and VSG data type is an online editing model of the latching logic. The online editing model may be configured to support a fixed-value service, enabling a configuration client to edit lockout logic online in a fixed-value manner. Of course, the online editing model may be configured to support a set-point service, enabling a configuration client to edit the lockout logic online in a set-point manner.
Preferably, the number of locked devices can be configured. Specifically, the device can be configured as a mis-locking prevention device for equipment in a single compartment, a mis-locking prevention device for equipment in a single section of bus, or a mis-locking prevention device for total station equipment. For the anti-misoperation locking of the device in a single interval, the output of the locking signal of the device may be issued in the form of GOOSE (Generic Object Oriented Substation Event). The latching contacts may be configured as an electrical interlock signal output. The measurement and control device realizes interval locking through the locking signal, and the intelligent terminal realizes process locking through the locking signal.
In this embodiment, the latching logic is received by the information obtaining unit 200 in the form of an MMS (Manufacturing message Specification). The device status information of the lock device is received by the information acquiring unit 200 in the form of GOOSE. The sending unit 400 may send the unlocking or locking processing result to the intelligent terminal in the form of GOOSE. The sending unit 400 may send the unlocking or locking processing result to the measurement and control device in a GOOSE format. In this embodiment, when the second model is configured as the real-time anti-error logic calculation mode, the unlocking or locking processing result is an unlocking signal and/or a locking signal. When the second model is configured to prevent the error host request mode, the unlocking or locking processing result is an unlocking request and/or a locking request.
In addition, the transformer substation anti-misoperation locking device can be connected with the intelligent terminal through a process layer bus of the transformer substation. The transformer substation anti-misoperation locking device can be connected with the measurement and control device through a substation control layer bus of the transformer substation. When the second model is configured to the anti-misoperation host request mode, the unlocking request and the locking request are sent to the intelligent terminal through the process layer bus and sent to the measurement and control device through the station control layer bus. When the second model is configured as a real-time error-prevention logic calculation mode without an error-prevention host, the unlocking signal and the locking signal calculated by the locking logic calculation unit 400 are sent to the intelligent terminal through the process layer bus and sent to the measurement and control device through the station control layer bus.
the working process of the transformer substation anti-misoperation locking device is further explained by two specific examples.
in one embodiment, the second model of the model configuration unit 100 is configured as a real-time anti-error logic computation mode without an anti-error host. The information obtaining unit 200 receives the device state information of the in-station device and the locking logic of the configured client from the intelligent device in real time, and sends the information to the locking logic calculating unit 300. The information acquisition unit 200 also sends the lockout logic configuring the client to the lockout logic managing unit 500. The latching logic management unit 500 determines the validity of the latching logic, and stores the latching logic if the latching logic is valid. The latching logic calculation unit 300 calculates the unlatch signal of the latched device based on the latching logic and the device state information of the devices in the station. When the unlocking signal or the locking signal of the locked device is calculated to be the unlocking signal or the locking signal, the sending unit 400 sends the unlocking signal or the locking signal calculated by the locking logic calculation unit 300 to the corresponding intelligent device through the process layer bus, and sends the unlocking signal or the locking signal to the corresponding measurement and control device through the station control layer bus. And the intelligent equipment and the measurement and control device execute corresponding operation according to the received unlocking signal or locking signal.
in this embodiment, the model configuration unit 100 may configure the first model, the second model, and the third model in a CID (intelligent electronic device configuration description) file.
In another embodiment, the second model of the model configuration unit 100 is configured to prevent the error host request mode. The information obtaining unit 200 receives device status information of the in-station device from the smart device in real time. The anti-error host sends the unlocking request to the information obtaining unit 200, and the information obtaining unit 200 receives the unlocking request and sends the unlocking request to the locking logic calculation unit 300. The locking logic calculation unit 300 judges whether the received unlocking request is legal or not according to the locking logic and the received equipment state information of the in-station equipment, and if the received unlocking request is legal, the unlocking request is sent to the measurement and control device and/or the intelligent terminal through the sending unit 400; and if the unlocking request is illegal, the unlocking request is not sent to the measurement and control device and the intelligent terminal. And the intelligent equipment and the measurement and control device execute corresponding unlocking operation according to the received unlocking request. After the remote control is completed, the anti-misoperation host sends the locking request to the information obtaining unit 200, and the confidence obtaining unit 200 receives the unlocking request and sends the unlocking request to the locking logic calculating unit 300. The latching logic calculation unit 300 directly sends the latching request to the measurement and control device and/or the intelligent terminal through the sending unit 400. And the intelligent equipment and the measurement and control device execute corresponding locking operation according to the received unlocking request.
