Description

Technical Field

[0001] The present invention relates to the field of power grid stabilization and control technology, and in particular to a non-stop transmission method, device, equipment and medium for a stabilization and control device of an intelligent substation. Background Art

[0002] In order to meet the development of digital and intelligent operation and maintenance of power grids, all newly commissioned substations are smart substations. The difference between smart substations and conventional substations is that information transmission is achieved by replacing cables with optical fibers and replacing electrical signals with optical signals. The stability control system is the second line of defense to ensure the safety and stability of the power system. The failure of the stability control device to operate may cause the destruction of the stability of the power grid and even cause large-scale power outages. Therefore, the failure of the stability control system to operate is the primary risk of power grid operation. The switch transmission of the stability control device is an important measure to prevent the failure of the stability control device to operate. However, the stability control device still adopts the design concept of conventional substations, and load shedding and tripping are achieved through external cables, which requires the laying of long cables to the corresponding interval intelligent terminals, and does not have a closing circuit, and cannot achieve non-stop transmission. In addition, the standard configuration has 16 load shedding outlets, and the test transmission outlet requires the load parts to be shut down at intervals, but in actual operation, multiple intervals cannot be shut down at the same time, resulting in a long transmission verification period for all outlets, low efficiency, and a high risk to the power grid.

[0058] The embodiments of the present invention provide a method, device, equipment and medium for non-stop transmission of a stabilization control device of an intelligent substation, which are used to solve the technical problem that the existing stabilization control device applied to the intelligent substation cannot realize non-stop transmission.

[0059] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] See also Figure 1 , Figure 1 A non-stop transmission principle diagram of a stabilization control device provided by an embodiment of the present invention includes: a stabilization control device, a stabilization control intelligent terminal, a load interval protection device, a GOOSE process layer switch, a load interval intelligent terminal and a load interval switch mechanism.

[0061] Among them, the load interval protection device refers to the line protection device corresponding to the load interval of the stabilization device. When a fault occurs in the line, the load interval protection device will issue a protection tripping command to trip the switch and cut off the line fault.

[0062] The GOOSE process layer switch refers to an optical switch that performs GOOSE release and forwarding in the process layer network, realizing shared forwarding of GOOSE release commands.

[0063] The load bay intelligent terminal refers to a device that receives the upper switch opening and closing optical signal commands and converts them into electrical signals for transmission to the load bay switch mechanism, and receives the switch position electrical signal information of the load bay switch structure and converts it into optical signals for publication to the upper GOOSE process layer switch.

[0064] The load interval switch mechanism refers to a mechanical mechanism that realizes the opening and closing of the switch and reflects the switch status.

[0065] The stabilization and control intelligent terminal is a device that converts photoelectric signals according to the conversion setting relationship. It is used to receive electrical signals such as load shedding export signals and test status signals of the stabilization and control device, optical signals such as protection tripping signals of the load interval protection device, and light signals of the switch position of the load interval intelligent terminal. It is also used to issue load shedding tripping optical signals when the load shedding action criterion is met, and to issue load closing optical signals after a set delay when the non-stop transmission test closing criterion is met.

[0066] In one example, the conversion setting relationship refers to the corresponding relationship between the photoelectric input of the stabilization and control intelligent terminal and the load opening and closing optical signal interchange conversion. When the corresponding electrical signal hard input and optical signal input of the stabilization and control device meet the conditions, the corresponding optical signal release is changed to 1. The relationship between the load shedding outlet of the stabilization and control device, the GOOSE release of the stabilization and control intelligent terminal, and the GOOSE subscription of the load interval intelligent terminal is shown in Table 1:

[0067] Table 1

[0068]

[0069] The corresponding contact of the load shedding outlet of the stabilizing control device is the load shedding interval after the stabilizing control device is actuated. When the corresponding interval, such as load 1, is shedding, the corresponding load 1 load shedding tripping outlet hard contact is closed; the load shedding electric signal input sequence number of the stabilizing control intelligent terminal is the contact sequence number connected to the corresponding load interval load shedding tripping outlet. In sequence, the load 1 outlet contact of the stabilizing control device is connected to input 1 of the stabilizing control intelligent terminal; the GOOSE release of the stabilizing control intelligent terminal is the GOOSE control block released by the stabilizing control intelligent terminal to the process layer network. When the above conversion relationship is satisfied, the corresponding GOOSE release is changed to 1, such as go 1.Tr is the tripping output release of load 1 interval, go1.Op is the closing output release of load 1 interval; the subscription of load 1-16 interval intelligent terminal refers to the GOOSE input corresponding to the load interval intelligent terminal, that is, when the GOOSE release of the stable control intelligent terminal changes to 1, the GOOSE input corresponding to the load interval intelligent terminal changes to 1. For example, when the stable control intelligent terminal go1.Tr changes to 1, the GGIO.T.stVal input of the load 1 interval intelligent terminal changes to 1, and the load 1 interval intelligent terminal sends a tripping command to the load interval switch mechanism to separate the switch.

[0070] See also Figure 2 ,exist Figure 1 On the basis of Figure 2 A flowchart of the steps of a non-stop transmission method for a stabilization control device of an intelligent substation provided by an embodiment of the present invention.

[0071] The present invention provides a non-stop power transmission method for a smart substation stabilization control device, which may specifically include the following steps:

[0072] Step 201, when it is detected that the stabilization control device is put into the test pressure plate, it is determined whether the stabilization control device meets the test state;

[0073] The test pressure plate is a special device used to isolate circuits or test protection devices in power systems.

[0074] In the embodiment of the present invention, when the stabilization control device is put into the test pressure plate, it is first necessary to determine whether the stabilization control device meets the test state.

[0075] In one example, the step of determining whether the stabilization control device meets the test state includes:

[0076] S11, determining whether the stabilization and control intelligent terminal receives the test status signal sent by the stabilization and control device;

[0077] S12: If yes, determine that the stabilization device meets the test state.

[0078] In the specific implementation, determining that the stabilization control device meets the test state means that after the stabilization control device is put into the test pressure plate, the stabilization device enters the test state and the stabilization control intelligent terminal receives the test state signal of the stabilization control device. If it is not satisfied, the stabilization control device state is determined to be abnormal, and the test state is recorded as abnormal, and the non-stop transmission is ended.

[0079] Step 202: If yes, the stabilization control device sends a load shedding exit signal to the stabilization control intelligent terminal;

[0080] Step 203, the stabilization and control intelligent terminal responds to the load shedding export signal and sends a trip command to the load interval intelligent terminal through the process layer switch;

[0081] In the embodiment of the present invention, when the stabilization and control device enters the test state, a load shedding exit signal may be sent to the stabilization and control intelligent terminal to trigger an interval load shedding operation.

[0082] The stabilization and control intelligent terminal confirms that it has received the corresponding load shedding signal, that is, the stabilization and control device issues a load 1 interval shedding signal, then the stabilization and control intelligent terminal receives the corresponding load 1 interval shedding input signal of the stabilization and control device; if the stabilization and control intelligent terminal does not receive the corresponding load interval shedding signal, it is judged that the load shedding of the stabilization and control device is abnormal, and it is recorded as an abnormality in the load shedding function or circuit of the stabilization and control device, and the non-stop transmission is ended.

[0083] When the stabilization and control intelligent terminal receives the cut-off input signal of the load 1 interval corresponding to the stabilization and control device, it can send a tripping command to the load interval terminal through the process layer switch (GOOSE process layer switch).

[0084] In one example, the stabilization and control intelligent terminal sends a GOOSE tripping command, which means that after the stabilization and control intelligent terminal receives the load cutting signal, the corresponding load interval tripping GOOSE command changes to 1. If a load 1 interval cutting signal is received, the load 1 interval cutting GOOSE command go1.Tr changes to 1.

[0085] Step 204, the load interval intelligent terminal responds to the trip command and performs a cut-off operation on the load interval corresponding to the load cut-off exit signal;

[0086] Step 205, determining whether the load interval is successfully removed;

[0087] In the embodiment of the present invention, the step of determining whether the load interval is successfully removed may specifically include the following sub-steps:

[0088] S51, determining whether the test status signal of the stabilization control device is 1;

[0089] S52, if yes, determine whether the stabilization control device meets the load shedding action criterion;

[0090] S53, if satisfied, determine whether the switch position signal of the load interval intelligent terminal corresponding to the load shedding exit signal changes from 1 to 0 after the load shedding exit signal changes position;

[0091] S54, if yes, determine whether the protection tripping signal of the load interval protection device remains at 0 within a time window of a preset length before the switch position of the load interval intelligent terminal changes to 0;

[0092] S55, if yes, determine that the load interval is successfully removed.

[0093] In the specific implementation, judging the corresponding load interval removal success condition is to judge whether the non-stop transmission test closing criterion is met, which is as follows:

[0094] 1. The test status signal of the stabilization device is 1;

[0095] 2. Satisfy the load shedding action criteria of the stabilization control device;

[0096] 3. After the load shedding output signal of the stabilizing control device changes, the switch position signal of the corresponding load interval intelligent terminal changes from 1 to 0;

[0097] 4. Within the first 5s time window before the switch position of the load bay intelligent terminal changes to 0, the protection tripping signal of the load bay protection device remains at 0.

[0098] Furthermore, in the embodiment of the present invention, step 205 may also include the following sub-steps:

[0099] S56, when it is determined that the load interval removal fails, determining whether the stabilization and control intelligent terminal receives a protection tripping signal;

[0100] S57, if not, it is determined that the load interval tripping circuit is abnormal, and the non-stop transmission is terminated;

[0101] S58, if yes, it is determined that there is a fault in the load interval, closing the switch on the fault is prohibited, and the non-stop transmission is terminated.

[0102] Specifically, when the closing criteria for the non-stop transmission test are not met, it is determined again whether the stable control intelligent terminal has received the interval protection tripping command. If not, the load interval tripping circuit abnormality is recorded and the non-stop transmission is terminated; if received, a fault is recorded in the load interval, closing the circuit breaker on the fault is prohibited, and the non-stop transmission is terminated.

[0103] Step 206, if yes, the stabilization and control intelligent terminal sends a closing command to the load interval intelligent terminal;

[0104] After judging that the load interval is successfully cut off, the stable control intelligent terminal can send a closing command to the load interval intelligent terminal through the GOOSE process layer switch after the set delay to close the corresponding load interval. If it is judged that the load 1 interval is successfully cut off, the load 1 interval closing GOOSE command go1.Op changes to 1; the corresponding load interval closing success judgment condition: within 500ms delay after the load interval closing GOOSE command is sent, the stable control intelligent terminal receives the load interval switch position from open to closed, otherwise it records the load interval closing circuit abnormality and ends the non-stop transmission.

[0105] Step 207, the load bay intelligent terminal responds to the closing command and performs a closing operation;

[0106] Step 208, when the closing is successful, it is determined that the stable control without power outage transmission is completed.

[0107] When the switch is closed successfully, it indicates that the stable control without power outage transmission is completed, and the result is recorded. The stable control without power outage transmission test of the corresponding load interval is completed, and the load shedding function and circuit of the corresponding load interval are recorded to be normal, and the non-stop power outage transmission is ended.

[0108] The present invention determines whether the stabilization control device meets the test state when it is detected that the stabilization control device is put into the test pressure plate; if so, the stabilization control device sends a load shedding exit signal to the stabilization control intelligent terminal; the stabilization control intelligent terminal responds to the load shedding exit signal and sends a tripping command to the load interval intelligent terminal through the process layer switch; after completing the operation corresponding to the tripping command, the load interval corresponding to the load shedding exit signal is cut off; it is determined whether the load interval is successfully cut off; if so, the stabilization control intelligent terminal sends a closing command to the load interval intelligent terminal; the load interval intelligent terminal responds to the closing command and performs the closing operation; when the closing is successful, it is determined that the stabilization control transmission is completed without power outage. The non-stop power transmission of the stabilization control device of the intelligent substation is realized.

[0109] For ease of understanding, the embodiments of the present invention are described below by using specific examples:

[0110] like Figure 3 As shown, Figure 3 The present invention provides a flowchart of an execution method of a non-stop transmission method of a smart substation stabilization control device according to an embodiment of the present invention.

[0111] When the stabilizing control device is put into the test pressure plate, first determine whether the stabilizing control device meets the test state. If not, determine that the state of the stabilizing control device is abnormal; if so, perform a transmission test on the stabilizing control device.

[0112] The transmission test of the stabilizing control device refers to the stabilizing control device issuing a tripping command for load shedding, and the stabilizing control intelligent terminal confirming receipt of the corresponding load shedding signal, that is, the stabilizing control device issues a load 1 interval shedding signal, then the stabilizing control intelligent terminal receives the corresponding load 1 interval shedding input signal of the stabilizing control device; if the stabilizing control intelligent terminal does not receive the corresponding load interval shedding signal, it is judged that the load shedding of the stabilizing control device is abnormal, and it is recorded as an abnormality in the load shedding function or circuit of the stabilizing control device, and the non-stop transmission is ended.

[0113] After receiving the load shedding signal, the stabling and controlling intelligent terminal can send a GOOSE tripping command and change the corresponding load interval tripping GOOSE command to 1. If a load 1 interval shedding signal is received, the load 1 interval shedding GOOSE command go1.Tr is changed to 1.

[0114] Among them, judging the successful removal condition of the corresponding load interval is to judge whether the closing criterion of the non-stop transmission test is met:

[0115] 1. The test status signal of the stabilizing device is 1;

[0116] 2. Meet the load shedding action criteria of the stabilization control device;

[0117] 3. After the load shedding output signal of the stabilizing control device changes, the switch position signal of the corresponding load interval intelligent terminal changes from 1 to 0;

[0118] 4. Within the first 5s time window before the switch position of the load interval intelligent terminal changes to 0, the protection tripping signal of the load interval protection device remains at 0.

[0119] When the closing criteria for the non-stop transmission test are not met, it is determined again whether the stable control intelligent terminal has received the interval protection tripping command. If not, the load interval tripping circuit abnormality is recorded and the non-stop transmission is terminated; if received, the load interval fault is recorded, closing the circuit breaker on the fault is prohibited, and the non-stop transmission is terminated.

[0120] After determining that the corresponding load interval is successfully cut off, the stable control intelligent terminal can send the GOOSE closing command to perform the closing operation according to the set delay. For example, if it is determined that the load 1 interval is successfully cut off, the load 1 interval closing GOOSE command go1.Op changes to 1; the corresponding load interval closing success judgment condition: within 500ms delay after the load interval closing GOOSE command is sent, the stable control intelligent terminal receives the load interval switch position from open to closed, otherwise it records the load interval closing circuit abnormality and ends the non-stop transmission.

[0121] When the corresponding load interval is closed successfully, it is determined that the stable control without power outage transmission is completed and the result is recorded.
