Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to an anti-error method, device, medium and equipment for provincial and local coordinated control of an AGC master station. Background Art

[0002] At present, the Automatic Generation Control (AGC) dispatching organization is mainly based on the coordinated control strategy between provinces and prefectures. All prefecture-level AGC units of the prefecture-level dispatching organization will be regarded as an equivalent unit in the provincial dispatching organization to participate in power allocation. After the equivalent unit is allocated a power value, the provincial AGC master station will send the power value to the prefecture-level AGC master station, and the prefecture-level AGC master station will actually allocate the power value to each prefecture-level AGC unit according to its allocation strategy.

[0003] Based on this provincial and local coordinated control strategy, data will be frequently exchanged between provincial and local dispatching agencies. However, once a data anomaly or operation error occurs, the AGC master station will be abnormal in regulation, which will cause a complete safety risk. Summary of the invention

[0004] Based on this, it is necessary to provide error-proof methods, devices, media and equipment for provincial and local collaborative control of the AGC master station to solve the problem that once a certain data is abnormal or an operation error occurs, the adjustment of the AGC master station will become abnormal, which will cause a complete safety risk.

[0005] In one embodiment, the prefecture-level AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, including:

[0006] The prefectural AGC master station receives the target output instruction issued by the provincial AGC master station; wherein the target output instruction is used to indicate the target total active power that all prefectural AGC units controlled by the prefectural AGC master station should achieve after adjustment;

[0007] The local AGC master station calculates a first power deviation between the target total active power and the current total active power of all local AGC units controlled, and discards the target output instruction if the first power deviation is greater than a preset first deviation threshold.

[0008] In one embodiment, the prefecture-level AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, including:

[0009] The prefectural AGC master station receives the power adjustment instruction issued by the provincial AGC master station; wherein the power adjustment instruction is used to indicate the target total adjustment power of all prefectural AGC units controlled by the prefectural AGC master station;

[0010] The local AGC master station calculates the current power to be adjusted of all local AGC units under its control, and if the target total adjustment power is opposite to the current power to be adjusted, the power adjustment instruction is discarded.

[0011] In one embodiment, the prefecture-level AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, including:

[0012] The prefectural AGC master station receives the power adjustment instruction issued by the provincial AGC master station; wherein the power adjustment instruction is used to indicate the target total adjustment power of all prefectural AGC units controlled by the prefectural AGC master station;

[0013] The local AGC master station calculates the current power to be adjusted of all local AGC units controlled by it, and calculates the second power deviation between the target total adjustment power and the current power to be adjusted. If the second power deviation is greater than the preset second deviation threshold, the power adjustment instruction is discarded.

[0014] In one embodiment, the prefecture-level AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, including:

[0015] The prefectural AGC master station sends prefectural time scale instructions to the provincial AGC master station, and receives provincial time scale instructions sent by the provincial AGC master station;

[0016] If the prefecture-level AGC master station detects that the deviation between the prefecture-level time scale and the provincial time scale is greater than the preset time scale deviation threshold, the operation of the prefecture-level AGC master station is suspended until the deviation is less than or equal to the preset time scale deviation threshold;

[0017] If the provincial AGC master station detects that the deviation between the local time scale and the provincial time scale is greater than the preset time scale deviation threshold, the equivalent programmable logic controller corresponding to the local AGC master station is switched to pause mode until the deviation is less than or equal to the preset time scale deviation threshold.

[0018] In one embodiment, the prefecture-level AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, including:

[0019] The prefectural AGC master station sends the prefectural operation status to the provincial AGC master station, and receives the provincial operation status sent by the provincial AGC master station;

[0020] If the prefecture-level AGC master station detects that the provincial-level operating status is abnormal, the operation of the prefecture-level AGC master station is suspended until the provincial-level operating status returns to normal;

[0021] If the provincial AGC master station detects that the local-level operating status is abnormal, the equivalent programmable logic controller corresponding to the local-level AGC master station will be switched to manual mode and an alarm will be sounded until the local-level operating status returns to normal.

[0022] An anti-error device for provincial and local coordinated control of an AGC master station is applied to an AGC dispatching system, wherein the AGC dispatching system includes a provincial AGC master station and a local AGC master station, and the anti-error device for provincial and local coordinated control of the AGC master station includes:

[0023] The error prevention module 201 is used for the local AGC master station to receive the parameter instruction issued by the provincial AGC master station, determine whether the parameter instruction is abnormal, and respond to the corresponding error prevention action according to the parameter instruction if the parameter instruction is abnormal.

[0024] A computer-readable storage medium stores a computer program. When the computer program is executed by a processor, the processor executes the steps of the error prevention method of the AGC master station provincial coordinated control.

[0025] A terminal device includes a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the steps of the error prevention method of the AGC master station provincial coordinated control.

[0026] The present invention provides an anti-error method, device, medium and equipment for provincial and local coordinated control of an AGC master station. After receiving a parameter instruction from a provincial AGC master station, the local AGC master station first determines whether the instruction is abnormal. If the instruction is found to be abnormal, the instruction is not executed immediately, but the corresponding anti-error measures are triggered to avoid system failures caused by abnormal instructions. This can effectively prevent abnormal adjustment of the AGC system and ensure the safe operation of the power grid. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0033] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] like Figure 1 As shown, Figure 1 The flowchart of the error prevention method of the provincial and local coordinated control of the AGC master station in one embodiment is applied to the AGC dispatching system, which includes a provincial AGC master station and a local AGC master station, wherein the provincial AGC master station is used to be responsible for the center of the overall provincial power dispatching, and issues instructions to the local AGC master station. The local AGC master station is used to execute the instructions issued by the provincial AGC master station and manage the generator sets in the local area.

[0036] The steps provided by the error prevention method of the AGC master station provincial and local coordinated control in this embodiment include:

[0037] S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, determines whether the parameter instruction is abnormal, and responds to the corresponding anti-misoperation according to the parameter instruction under the premise that the parameter instruction is abnormal, so as to prevent the AGC dispatching system from operating abnormally.

[0038] Among them, parameter instructions are control instructions issued by the provincial AGC master station, usually including information such as power distribution and load forecast. If the local AGC master station determines that the content of the parameter instruction does not meet the preset standard or logic, such as the value exceeds the reasonable range or the format is wrong, it will determine that the parameter instruction is abnormal and then take corresponding measures, such as alarm, automatic switching to safe mode and other anti-misoperation measures.

[0039] Exemplarily, a real-time monitoring module is installed in the local AGC master station to detect the received parameter instructions in real time. If the power deviation between the power instruction issued by the provincial AGC master station and the power instruction issued last time is greater than the preset threshold for multiple times (for example, 5 times), the abnormality is identified and an alarm is triggered to avoid applying the unreasonable instruction to the generator set.

[0040] In the above-mentioned error prevention method of provincial and local coordinated control of the AGC master station, after receiving the parameter instruction from the provincial AGC master station, the local AGC master station will first determine whether the instruction is abnormal. If the instruction is found to be abnormal, the instruction will not be executed immediately, but the corresponding error prevention measures will be triggered to avoid system failures caused by abnormal instructions. This can effectively prevent abnormal adjustment of the AGC system and ensure the safe operation of the power grid.

[0041] In one embodiment, S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, and responds to the corresponding anti-misoperation according to the parameter instruction to prevent the AGC dispatching system from running abnormally, which specifically includes the following steps:

[0042] A1. The prefecture-level AGC master station receives the target output command issued by the provincial-level AGC master station.

[0043] Among them, the target output instruction is used to indicate the target total active power that all local-level AGC units controlled by the local-level AGC master station should achieve after adjustment.

[0044] A2. The local AGC master station calculates the first power deviation between the target total active power and the current total active power of all local AGC units controlled. If the first power deviation is greater than the preset first deviation threshold, the target output instruction is discarded.

[0045] Among them, the first power deviation is the difference between the target total active power and the current total active power of the local AGC group. If the deviation exceeds the preset first deviation threshold, it indicates that the adjustment amplitude is too large, and the adjustment may cause unstable operation or safety risks. At this time, the abnormal instruction is discarded and the alarm is executed, so that the AGC dispatching system has an automatic protection function during operation.

[0046] In one embodiment, S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, and responds to the corresponding anti-misoperation according to the parameter instruction to prevent the AGC dispatching system from running abnormally, which specifically includes the following steps:

[0047] B1. The prefectural-level AGC master station receives the power adjustment command issued by the provincial-level AGC master station.

[0048] The power regulation instruction is used to indicate the target total regulation power of all local AGC units controlled by the local AGC master station.

[0049] B2. The local AGC master station calculates the current power to be adjusted of all local AGC units under its control. If the target total adjustment power is opposite to the current power to be adjusted, the power adjustment instruction is discarded.

[0050] The calculation formula of the current power to be adjusted is expressed as:

[0051] ΔP=P des -P tot

[0052] In the above formula, ΔP represents the current power to be adjusted, P des represents the expected power generation, P tot Indicates the current total actual power generation. If the target total regulated power is opposite to the current power to be regulated (for example, the target regulated power is required to increase, but the current power to be regulated is reduced), the instruction is judged to be abnormal and the power regulation instruction is directly discarded to avoid the adverse effects of executing the wrong instruction on the system.

[0053] In one embodiment, S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, and responds to the corresponding anti-misoperation according to the parameter instruction to prevent the AGC dispatching system from running abnormally, which specifically includes the following steps:

[0054] C1. The prefectural-level AGC master station receives the power adjustment command issued by the provincial-level AGC master station.

[0055] The power regulation instruction is used to indicate the target total regulation power of all local AGC units controlled by the local AGC master station.

[0056] C2. The local AGC master station calculates the current power to be adjusted of all local AGC units controlled by it, and calculates the second power deviation between the target total adjustment power and the current power to be adjusted. If the second power deviation is greater than the preset second deviation threshold, the power adjustment instruction is discarded.

[0057] If the second power deviation is greater than the preset "second deviation threshold", that is, the difference between the two exceeds the acceptable range, the local AGC master station will discard the power adjustment instruction to avoid executing the abnormal instruction.

[0058] The above-mentioned error prevention method detects power deviations, thereby identifying and filtering out abnormal instructions at the source, providing an effective exception handling mechanism for the AGC system, which can significantly reduce the complete safety risks caused by data anomalies and operation errors.

[0059] In one embodiment, S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, and responds to the corresponding anti-misoperation according to the parameter instruction to prevent the AGC dispatching system from running abnormally, which specifically includes the following steps:

[0060] D1. The local AGC master station sends local time scale instructions to the provincial AGC master station, and receives provincial time scale instructions sent by the provincial AGC master station.

[0061] Among them, the local time scale is the time scale used by the local AGC master station, which is used to synchronize and verify the instruction transmission and execution time between the local master station and the provincial master station. The provincial time scale is the time scale of the provincial AGC master station, which is compared with the local time scale to ensure the time consistency within the system.

[0062] D2 If the prefectural AGC master station detects that the deviation between the prefectural time scale and the provincial time scale is greater than the preset time scale deviation threshold, the operation of the prefectural AGC master station is suspended until the deviation is less than or equal to the preset time scale deviation threshold.

[0063] The time scale deviation threshold is the maximum allowable time deviation between the prefectural time scale and the provincial time scale. If the time deviation exceeds this value, it is considered as time inconsistency, which may cause system operation errors. The prefectural configuration has a consistency check program. If the prefectural AGC master station detects that the deviation between the prefectural time scale and the provincial time scale is greater than the preset time scale deviation threshold, the work of the prefectural AGC master station will be suspended, and the prefectural time scale will be automatically adjusted to match the provincial time scale to ensure time synchronization until the deviation is less than or equal to the preset time scale deviation threshold.

[0064] D3. If the provincial AGC master station detects that the deviation between the local time scale and the provincial time scale is greater than the preset time scale deviation threshold, the equivalent programmable logic controller corresponding to the local AGC master station is switched to the pause mode until the deviation is less than or equal to the preset time scale deviation threshold.

[0065] Similarly, provincial master stations are all equipped with consistency check programs. If the provincial AGC master station detects that the deviation between the local time scale and the provincial time scale is greater than the preset time scale deviation threshold, the equivalent programmable logic controller corresponding to the local AGC master station will be switched to pause mode, thereby automatically adjusting the local time scale to match the provincial time scale to ensure time synchronization until the deviation is less than or equal to the preset time scale deviation threshold.

[0066] The introduction of this time-scale consistency check mechanism avoids data errors and control deviations caused by time inconsistency, thereby improving the reliability and stability of the scheduling process.

[0067] In one embodiment, S101, the local AGC master station receives the parameter instruction issued by the provincial AGC master station, and responds to the corresponding anti-misoperation according to the parameter instruction to prevent the AGC dispatching system from running abnormally, which specifically includes the following steps:

[0068] E1. The prefectural AGC master station sends the prefectural operation status to the provincial AGC master station, and receives the provincial operation status sent by the provincial AGC master station.

[0069] Among them, the prefecture-level operation status is the working status information of the prefecture-level AGC master station, including information on whether its operation is normal, and is used to monitor whether the prefecture-level AGC master station has any abnormalities. The provincial-level operation status is the working status information of the provincial-level AGC master station, including information on whether its operation is normal, and is used to ensure that the control system of the provincial-level AGC master station is in a stable state.

[0070] The prefectural-level AGC master station and the provincial-level AGC master station periodically send and compare their respective operating statuses to detect anomalies.

[0071] E2. If the prefecture-level AGC master station detects that the provincial-level operating status is abnormal, the operation of the prefecture-level AGC master station will be suspended until the provincial-level operating status returns to normal.

[0072] E3. If the provincial AGC master station detects that the local-level operating status is abnormal, the equivalent programmable logic controller corresponding to the local-level AGC master station will be switched to manual mode and an alarm will be sounded until the local-level operating status returns to normal.

[0073] Through this two-way operation status detection mechanism, abnormal conditions can be discovered and handled in a timely manner, effectively avoiding failures or loss of control caused by abnormal conditions during system operation.

[0074] In one embodiment, Figure 2 As shown, an anti-error device for provincial and local coordinated control of an AGC master station is proposed, which is applied to an AGC dispatching system. The AGC dispatching system includes a provincial AGC master station and a local AGC master station. The anti-error device for provincial and local coordinated control of the AGC master station includes:

[0075] The error prevention module 201 is used for the local AGC master station to receive the parameter instruction issued by the provincial AGC master station, determine whether the parameter instruction is abnormal, and respond to the corresponding error prevention action according to the parameter instruction if the parameter instruction is abnormal.
