Description

Technical Field

[0001] The present invention relates to the technical field of power system automation control, and in particular to an automatic power generation control method and system based on a secondary distribution strategy. Background Art

[0002] When receiving a new power setting value, the traditional AGC system will compare the difference between the setting value and the actual power generation with the preset small load threshold value to determine the load distribution method. When the difference exceeds the threshold value, the large load is distributed, that is, the load is distributed in proportion to the adjustable capacity of each unit. When the difference does not exceed the threshold value, the largest unit within the adjustable range will be selected for adjustment.

[0003] Although this method can allocate adjustable capacity, it will also cause the largest unit to be under load pressure for a long time, which will have a serious impact on the life of the equipment and increase the operation and maintenance cycle. In some cases, it is impossible to obtain the optimal resource allocation, resulting in poor power system efficiency. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0051] Example 1

[0052] Reference Figure 1, which is the first embodiment of the present invention, and provides an automatic power generation control method based on a secondary allocation strategy, comprising:

[0053] S1. Obtain the power setting value issued by the AGC system and the actual value generated by the current AGC system to determine whether the power setting value is valid;

[0054] Furthermore, the power setting value issued by the AGC system is transmitted to the generator set. The transmission process performs data interaction according to the communication protocol. At the same time, the real-time frequency sent by the AGC system is monitored and the actual value of the current AGC system is obtained.

[0055] Preferably, the communication protocol in the AGC system is selected as version 104 in the IEC 60870-5 series;

[0056] It should be noted that IEC 60870-5-104 has excellent flexibility and reliability compared to traditional power monitoring and control, and has better security and performance than version 101;

[0057] S2. If the power setting value is valid, the difference between the power setting value and the actual value of the current AGC system is obtained according to the power setting value issued by the AGC system and the actual value generated by the current AGC system, and it is determined whether the difference exceeds the small load threshold value. Otherwise, it is marked that the power setting value issued by the AGC system is abnormal and needs to be reset;

[0058] Furthermore, the power setting value sent by the AGC system is marked as abnormal, triggering the abnormal value alarm mechanism, forcibly ending the current data transmission process through IEC60870-5-104, and uploading the result to the AGC system;

[0059] It should be noted that the AGC system will save each uploaded abnormal value result and generate an abnormal value log, which will be recorded by professionals at regular intervals;

[0060] S3. When the difference exceeds the small load threshold, the secondary allocation strategy is used for processing. If it does not exceed, the small load regulation mode is used and the primary allocation is used for processing;

[0061] Specifically, the secondary allocation strategy is divided into proportional allocation strategy and incremental allocation strategy;

[0062] Furthermore, the proportional allocation strategy steps are as follows:

[0063] Assume that the load is adjusted by a generator set Ai, the adjustable intervals of the generator set Ai are Ri, the current actual values ​​are Pi, and the load states of the generator set are obtained, which are -1, 0, and 1 respectively;

[0064] Furthermore, the current load state is compared with the adjustable range of the generator set;

[0065] Specifically, the comparison process is: if the current load state is -1, the adjustable interval is expressed as: Ri{1}; if the current load state is 0, the adjustable interval is expressed as: Ri{1or-1}; if the current load state is 1, the adjustable interval is expressed as: Ri{-1};

[0066] Among them, -1 means full load, 0 means no load, and 1 means partial load;

[0067] It should be noted that the meaning of the adjustable interval Ri{1} is that when the generator set is in a full load state, it can be adjusted to a partial load state; the meaning of the adjustable interval Ri{1or-1} is that when the generator set is in a no-load state, it can be adjusted to a partial load or full load state; the meaning of the adjustable interval Ri{-1} is that when the generator set is in a partial load state, it can be adjusted to a full load state;

[0068] Furthermore, the adjusted load is calculated and proportionally distributed;

[0069] Specifically, the formula for calculating the adjusted load is as follows:

[0070] Pset=Ai / (R1+R2)*L+Pi

[0071] Among them, L is the total load, and Pset represents the adjusted load;

[0072] Furthermore, according to the result obtained by Pset, an adjustment signal is sent through the control system of the generator set Ai to adjust the load of each generator;

[0073] It should be noted that each generator adjusts the load after receiving the adjustment signal, and transmits the adjusted load to the generator set, and the generator set updates the current load and transmits it to the AGC system for storage;

[0074] Further, the incremental allocation strategy, the steps are as follows:

[0075] The remaining load amount distributed in equal proportion is used as the current incrementally distributed load amount, and the difference between the current incrementally distributed load amount and the load of the generator set is calculated;

[0076] It should be noted that usually there will be no remaining load after proportional distribution, but it is not excluded that the AGC system calls generators in different areas or adds generators to the generators, so the remaining load in proportional proportion needs to be used as the current transfer and distribution load;

[0077] Furthermore, the generator sets participating in the allocation are selected to adjust the adjustable capacity of the generator sets. Adjust to meet the load difference, and the adjustable capacity S must be greater than the load difference;

[0078] Specifically, the load difference formula is expressed as:

[0079]

[0080] Among them, R is the difference between the current incrementally allocated load and the load of the generator set, and Preal is the load of the generator set;

[0081] Furthermore, the generators selected for allocation are sorted so that the generators with the smallest load are at the head of the queue and the generators with the largest load are at the tail of the queue, and the adjustable capacity is allocated cyclically according to the increasing formula;

[0082] It should be noted that the generators included in the generator set are also load-distributed in the same manner as the generator set. The generator set can be regarded as the outermost loop, and the generators included are the innermost loop;

[0083] Specifically, when the cycle of generator set 1 is completed, the generators contained therein are also allocated; then generator set 2 is started, and so on;

[0084] Specifically, the incremental formula is expressed as:

[0085] Assuming the increasing ratio is d, the i-th cycle allocation is expressed as:

[0086] Q i =L*R+r i

[0087] r i =LQ i

[0088] For the i+1th time, the cyclic allocation is expressed as:

[0089] r i+1 =r i +(1-d)

[0090] Among them, L r is the current load, R is the difference between the current incrementally allocated load and the load of the generator set; r i is the load remaining after each cycle;

[0091] Furthermore, when the load difference is 0, the allocation is completed, otherwise it is necessary to reselect the generator sets participating in the allocation and readjust the load difference;

[0092] Specifically, in one allocation, that is, allocation according to a fixed load, if there are two generator sets that need to adjust the load, their adjustable ranges are 200MW and 300MW respectively. If the load to be adjusted is 40MW, it can be allocated according to a fixed ratio of 20:30, that is, 16MW is allocated to the first generator set and 24MW is allocated to the second generator set.

[0093] Furthermore, this embodiment also provides an automatic power generation control system based on a secondary allocation strategy, comprising:

[0094] The power system control center obtains the power setting value issued by the AGC system and the actual value generated by the current AGC system, and determines whether the power setting value is valid;

[0095] The power judgment module, if the power setting value is valid, obtains the difference between the power setting value and the actual value of the current AGC system according to the power setting value issued by the AGC system and the actual value generated by the current AGC system, and judges whether the difference exceeds the small load threshold value, otherwise it marks that the power setting value issued by the AGC system is abnormal and needs to be reset;

[0096] The load distribution module adopts a secondary distribution strategy to process when the difference exceeds the small load threshold value; if it does not exceed the small load regulation mode, the primary distribution strategy is used for processing.

[0097] This embodiment further provides a computer device, which is applicable to the case of an automatic power generation control method based on a secondary allocation strategy, and includes:

[0098] Memory and processor; the memory is used to store computer executable instructions, and the processor is used to execute computer executable instructions to implement the automatic power generation control method based on the secondary distribution strategy proposed in the above embodiment.

The processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory.

[0100] This embodiment further provides a storage medium on which a computer program is stored. When the program is executed by a processor, the automatic power generation control method based on the secondary allocation strategy proposed in the above embodiment is implemented.
