Description

Technical Field

[0001] This application relates to the technical field of generator power supply, and particularly to a power supply method, system, device, electronic device and storage medium. Background Art

[0002] Currently, large generator sets usually supply power to loads as independent power sources, such as large thermal power plants, hydropower plants, large gas turbines, etc. For small generator sets, such as small gas turbines, gas internal combustion engines, diesel engines and other generator sets, in order to ensure power supply continuity, they need to be connected to the power grid to supply power to loads.

[0003] Among them, when the generator set is operating in parallel with the power grid, there is an operation mode of grid connection without power injection. In this mode, all the electric energy generated by the generator set is supplied to the load, and it is not allowed to send electric energy to the power grid. Only the load is allowed to absorb electric energy from the power grid. The output power of the generator set will be automatically adjusted according to the load in its own plant area. If the electric energy generated by the generator set is sent to the power grid, the anti-backfeed power device will cut off the circuit breaker of the generator set, which will affect the normal operation of the unit.

[0004] In the prior art, when the generator set operates in the above grid connection without power injection mode, when it is necessary to manually adjust the output power of the generator due to insufficient fuel of the generator set, and the adjusted output power is incorrect or the load suddenly decreases, it is easy to cause the output power of the generator set to be greater than the total load power, resulting in the generator set backfeeding power to the power grid, affecting the normal operation of the generator set and reducing the economic benefits of users.

This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0071] To solve the technical problem in the prior art that when a generator set and a power grid operate in a grid-connected but non-power-injection mode, the output power of the generator set is greater than the total load power, resulting in the generator set discharging power back to the power grid, affecting the normal operation of the generator set and reducing the economic benefits of users, the present application provides a power supply method, system, device, electronic device, and storage medium. During the grid-connected operation of the generator module and the power grid module, since the generator set has different power supply modes, the target power generation power of the power generation module can be determined in real time according to the power supply mode of the generator set, the current total load power of the power supply system, and the current power grid power supply power of the power grid module. Since the target power generation power determined in real time is less than the total load power, it is possible to prevent the power generation power of the generator module from being greater than the total load power due to misoperation or sudden reduction of the load power, thereby avoiding the generator module from delivering electric energy to the power grid, ensuring the continuous normal operation of the generator set, and improving the economic benefits of users.

[0076] The above power grid module 13 refers to the power grid in the power supply system 10, which refers to the overall composition of substations and transmission and distribution lines of various voltages in the power system. The power grid can include three units: transformation, transmission, and distribution. Its task is to transmit and distribute electric energy and change the voltage.

[0077] The above first current measurement module 14 and second current measurement module 15 both refer to modules for measuring current values. They can be current transformers or other modules for measuring current. Moreover, the first current measurement module 14 and the second current measurement module 15 can be the same measurement module or different measurement modules.

[0080] The output terminals of the above-mentioned first current measurement module 14 and first voltage measurement module 16 (the output terminal O2 of the first current measurement module and the output terminal O3 of the first voltage measurement module) are both connected to the input terminal I1 of the control module 11.

[0082] The output terminals of the above-mentioned second current measurement module 15 and second voltage measurement module 17 (the output terminal O5 of the second current measurement module 15 and the output terminal O6 of the second voltage measurement module 17) are both connected to the input terminal I1 of the control module 11.

[0085] The above-mentioned control module 11 can be used to execute the power supply method provided in this application.

[0086] In the embodiment of this application, the control module 11 can obtain the grid current and grid voltage of the power grid module 13 through the first current measurement module 14 and the first voltage measurement module 16, so as to determine the grid power of the power grid module 13 according to the grid current and grid voltage.

Since the determined target generated power is always less than the total load power of the power supply system 10 in real time, it is possible to prevent the situation where the generated power of the generator module is greater than the total load power due to misoperation or sudden reduction of the load power, thereby avoiding the generator module from transmitting electric energy to the power grid, realizing the continuous and normal operation of the generator set, and improving the economic benefits of users.

Therefore, it can prevent the power generation power of the generator module from being greater than the total load power due to misoperation or sudden reduction of the load power, thereby avoiding the generator module from transmitting electric energy to the power grid, realizing the continuous and normal operation of the generator set, and improving the economic benefits of users.

[0100] The following further explains the power supply method provided by the present application with specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation to the embodiments of the present invention.

[0101] See Figure 3 , which is a flowchart of an embodiment of a power supply method provided by an embodiment of the present application. As an embodiment, Figure 3 The shown process can be applied to the control module in the power supply system, such as Figure 1 the control module 11 in the power supply system 10 shown. As shown in Figure 3As shown, the process may include the following steps:

[0102] Step 301: Determine the current power supply mode of the power supply system and the total load power corresponding to the current power supply system.

[0103] The above-mentioned power supply system refers to a system used to supply power to a load. In the embodiments of the present application, the power supply system may include a control module, a generator module, and a power grid module. For example Figure 1 The power supply system 10 shown. Further, the generator module and the power grid module in the power supply system can operate in a mode of grid connection without power injection. In this mode, all the electric energy generated by the generator module is supplied to the load, and it is not allowed to transmit electric energy to the power grid module. Only the load is allowed to absorb electric energy from the power grid module. The output power of the generator module can be automatically adjusted according to the load of its own plant area. Among them, if the electric energy generated by the generator module is transmitted to the power grid, the anti-backfeed power device will cut off the circuit breaker of the generator module, affecting the normal operation of the unit.

[0104] The above-mentioned power supply mode refers to the operation mode in which the power supply system currently supplies power to the load end, and it may include but is not limited to: a power adaptive mode and a constant power output mode. Among them, the above-mentioned power adaptive mode means that the actual output power of the power grid can change according to the load change of the power supply system; the above-mentioned constant power output mode means that a rated power is set for the generator module and the power grid mode, so that the generator module and the power grid module output electric energy according to the corresponding rated power.

[0105] The above-mentioned total load power refers to the total power required by the current load end of the power supply system.

[0106] In one embodiment, the user can set the power supply mode of the power supply system through the control module. Based on this, the control module can directly obtain the current power supply mode of the power supply system.

[0107] As an optional implementation manner, the user can set the power supply mode of the power supply system through the visualization interface of the control module. Based on this, the control module can obtain the current power supply mode of the power supply system through this visualization interface.

[0108] In one embodiment, the control module can obtain the total load power corresponding to the current power supply system in real time or at regular intervals.

[0109] As an optional implementation manner, a power measurement device can be respectively connected between the control module and the generator module, and between the control module and the power grid module. Based on this, the control module can respectively measure the grid power of the current power grid module and the power generation power of the current generator module through the corresponding power measurement devices. Then, the above-mentioned grid power and power generation power can be added to obtain the total load power corresponding to the current power supply system.

[0110] As an exemplary implementation, as Figure 1 shown, a first current measurement module and a first voltage measurement module can be respectively connected between the control module and the power grid module. Based on this, the control module can obtain the first current value of the power grid module through the first current measurement module, and obtain the first voltage value of the power grid module through the first voltage measurement module. After that, the above first current value can be multiplied by the above first voltage value to obtain the power grid power of the power grid module.

[0111] Optionally, a second current measurement module and a second voltage measurement module can be respectively connected between the control module and the generator module. Based on this, the control module can obtain the second current value of the generator module through the above second current measurement module, and obtain the second voltage value of the generator module through the second voltage measurement module. After that, the above second current value and the above second voltage value can be multiplied to obtain the power generation power of the generator module.

[0112] Step 302, obtain the current power grid power supply of the power grid module in the above power supply mode.

[0113] The above power grid power supply refers to the current power supply of the power grid module. Among them, when the power supply mode of the power supply system is different, its corresponding power supply may also be different.

[0114] In the embodiments of the present application, when the power supply system is in different power supply modes, the power grid power supply of its power grid module may be different. Therefore, the control module can determine the current power grid power supply of the power grid module according to the current power supply mode.

[0115] As an optional implementation, when the power supply mode of the power supply system is the power adaptive mode, at this time, the power grid power supply of the power grid module is the following power. At this time, the maximum load power included in the total load power can be obtained, and the power supply characteristic curve of the generator module can be obtained, and the current power grid power supply of the power grid module can be determined according to the above maximum load power and the power supply characteristic curve. Among them, the above maximum load power refers to the load power corresponding to the maximum load included in the total load power. The above power supply characteristic curve is used to characterize the output power change characteristics of the generator module, which can characterize the loading capacity response of the generator module. Among them, different generator modules may correspond to different power supply characteristic curves, that is, the loading capacity responses are different. For example, the loading capacity response of a gas internal combustion engine is less than that of a gas turbine, and the loading capacity response of a gas turbine is less than that of a diesel internal combustion engine.

[0116] As an exemplary implementation, the instantaneous change power and change time of the generator module can be determined according to the above power supply characteristic curve. After that, the current power grid power supply of the power grid module can be determined according to the above maximum load power and the change power.

[0117] As an implementation, the current grid power supply of the grid module can be obtained by subtracting the above-mentioned variable power from the above-mentioned maximum load power.

[0118] For example, assume that the load power of the maximum load is 500 kW, the output power of the generator module is 1000 kW, and the following power of the grid module is 200 kW. Then the total power can be 1200 Kw. Continuing to assume that the maximum load power of 500 kW is instantaneously cut off, and the cut-off time is 1 second. Assume that the power that the generator module can decrease within 1 second is 200 kW. Then the remaining power generation is 800 kW, and the on-site load is only 700 Kw at this time. This means that 100 kw will be transmitted to the grid module, causing reverse power supply. Therefore, it can be determined that the grid power supply of the grid module is 300 Kw to prevent the generator module from supplying power to the grid module.

[0119] As another exemplary implementation, a current measurement module (such as Figure 1 the first current measurement module 14 shown) and a voltage measurement module (such as Figure 1 the first voltage measurement module 16 shown) can be respectively connected between the control module and the grid module. Based on this, the control module can obtain the current value of the grid module through the above-mentioned current measurement module, and obtain the voltage value of the grid module through the voltage measurement module. Then, the above-mentioned current value can be multiplied by the above-mentioned voltage value to obtain the grid power supply of the grid module.

[0120] As another optional implementation, when the above-mentioned power supply mode is a constant power output mode, at this time, there may be a manually set grid power setting value for the grid module. At this time, the grid module can supply power with the grid power setting value or other powers. Therefore, the current grid power supply of the grid module can be directly obtained through the power measurement module.

[0121] As an exemplary implementation, a current measurement module (such as Figure 1 the first current measurement module 14 shown) and a voltage measurement module (such as Figure 1 the first voltage measurement module 16 shown) can be respectively connected between the control module and the grid module. Based on this, the control module can obtain the current value of the grid module through the above-mentioned current measurement module, and obtain the voltage value of the grid module through the voltage measurement module. Then, the above-mentioned current value can be multiplied by the above-mentioned voltage value to obtain the grid power supply of the grid module.

[0122] Step 303: Determine the target power generation of the generator module according to the above-mentioned power supply mode, total load power, and grid power supply, and control the generator module to generate power according to the above-mentioned target power generation, where the above-mentioned target power generation is less than the above-mentioned total load power.

[0123] The above-mentioned target power generation refers to the power generation of the generator module after adjustment according to the above-mentioned power supply mode, total load power, and grid power supply power determined by the control module. This target power generation can be less than the total load power. Therefore, it can prevent the power generation of the generator module from being greater than the total load power caused by misoperation or sudden reduction of the load power, thereby avoiding the generator module from transmitting electric energy to the grid.

[0124] In the embodiment of the present application, after determining the power supply mode of the power supply system, the corresponding total load power, and the grid power supply power of the grid module, the control module can adjust the power generation of the generator module according to the above-mentioned power supply mode, the above-mentioned total load power, and the grid power supply power of the grid module to determine the target power generation of the generator module. Then, it can control the generator module to supply power according to the above-mentioned target power generation. Since the target power generation is the power generation that is adjusted in real time and is less than the total load power of the power supply system, by controlling the power generation of the generator module according to the target power generation, it can prevent the power generation of the generator module from being greater than the total load power caused by misoperation or sudden reduction of the load power, thereby avoiding the generator module from transmitting electric energy to the grid.

[0125] As for how to specifically determine the target power generation of the generator module, it will be described separately in the following through Figure 4 and Figure 5 The shown processes will be explained, and it will not be elaborated here first.

[0126] The technical solution provided by the embodiment of the present application determines the current power supply mode of the power supply system and the current total load power corresponding to the power supply system, obtains the current grid power supply power of the grid module under the above-mentioned power supply mode, determines the target power generation of the generator module according to the above-mentioned power supply mode, total load power, and grid power supply power, and controls the generator module to generate power according to the above-mentioned target power generation, where the above-mentioned target power generation is less than the above-mentioned total load power. This technical solution, during the parallel operation of the generator module and the grid module, since there are different power supply modes for the generator set, it can determine the target power generation of the power generation module in real time according to the power supply mode of the generator set, the current total load power of the power supply system, and the current grid power supply power of the grid module. And since the target power generation determined in real time is less than the total load power, it can prevent the power generation of the generator module from being greater than the total load power caused by misoperation or sudden reduction of the load power, thereby avoiding the generator module from transmitting electric energy to the grid, achieving the continuous and normal operation of the generator set and improving the economic benefits of users.

[0127] See Figure 4 , which is the flowchart of the embodiment of another power supply method provided by the embodiment of the present application. Figure 4The process shown below Figure 3 is based on the process shown below, and describes how to determine the target power generation of the generator module specifically when the power supply mode is the power adaptive mode. As Figure 4 shown, this process may include the following steps:

[0128] Step 401: Determine the maximum power generation of the generator module.

[0129] The above-mentioned maximum power generation refers to the maximum power generation achieved by the generator module. Among them, different generator modules may have different maximum power generations. For example, the maximum output power of a gas internal combustion engine can be the rated power of the unit, while the power of a gas turbine is restricted by various conditions, such as control temperature, fuel regulating valve opening, etc. Therefore, the maximum output power of a gas turbine is not a fixed value, but its current power when the gas turbine reaches the limiting conditions.

[0130] In the embodiment of the present application, when determining the target power generation of the generator module, the control module can obtain the maximum power generation of the generator module.

[0131] As an optional implementation, the maximum power generation of the generator module can be pre-stored in a preset storage medium within the control module. Based on this, the control module can directly obtain the maximum power generation of the generator module from the above storage medium.

[0132] Step 402: Determine the target power generation of the generator module according to the above-mentioned maximum power generation, total load power, and grid power supply.

[0133] The above-mentioned total load power refers to the total power of the current load of the power supply system determined in step 301.

[0134] The above-mentioned grid power supply refers to the current power supply of the grid module within the power supply system determined in step 301.

[0135] In the embodiment of the present application, when the power supply system operates in the power adaptive mode, after the control module determines the maximum power generation of the generator module, it can determine the target power generation of the generator module according to the above-mentioned maximum power generation, total load power of the power supply system, and grid power supply.

[0136] As an optional implementation, the total load power can be subtracted from the grid power supply to obtain the remaining load power (for ease of description, hereinafter referred to as "the first remaining load power").

[0137] After that, the above-mentioned maximum power generation and the above-mentioned first remaining load power can be compared to obtain a comparison result.

[0138] Optionally, when the comparison result indicates that the maximum power generation is less than or equal to the first remaining load power, the target power generation of the generator module can be determined as the maximum power generation.

[0139] Optionally, when the comparison result indicates that the maximum power generation is greater than the first remaining load power, if the total load power is less than the grid power supply power, it means that the grid power supply power of the grid module can meet the power supply demand for the load at this time. Therefore, the target power generation of the generator module can be determined as a preset value. The preset value can be a relatively small power value, such as 0.

[0140] Optionally, if the total load power is greater than or equal to the grid power supply power, it means that the grid power supply power of the grid module cannot meet the power supply demand for the load at this time, and the generator module needs to supply power to the load at the same time. Therefore, the target power generation of the generator module can be determined as the first remaining load power.

[0141] For example, assume that the power generation of the grid module for the load is 500 Kw (adjustable), and this power is the following power. That is, if the maximum output power of the generator module is higher than the total load power, the output power of the generator module can be the total load power - the following power (500 kW).

[0142] Based on this, in order to avoid excessive power generation of the generator module, when the maximum power generation of the generator module ≤ the total load power - 500 kW, the target power generation of the generator module can be the maximum power generation.

[0143] Optionally, when the maximum power generation of the generator module > the total load power - 500 kW, if the total load power < 500 kW, the target power generation of the generator module can be determined as 0.

[0144] Optionally, if the total load power ≥ 500 kW, the target power generation of the generator module can be the total load power - 500 kW, and this target power generation can change according to the load power at any time.

[0145] The technical solution provided by the embodiments of the present application determines the maximum power generation of the generator module, and determines the target power generation of the generator module according to the maximum power generation, the total load power, and the grid power supply power. This technical solution can adjust the power generation of the generator module by referring to the maximum power generation of the generator module and according to the current total load power and grid power supply power, so that in case of misoperation or sudden reduction of the load power, the power generation of the generator module can be timely reduced, so that the power generation of the generator module is less than the total load power in time, avoiding the power supply from the generator module to the grid module, realizing the continuous and normal operation of the generator set, and improving the economic benefits of users.

[0146] See Figure 5 , which is the flowchart of another power supply method provided by the embodiment of the present application. Figure 5 The process shown Figure 3 On the basis of the process shown, it describes how to determine the target power generation power of the generator module when the power supply mode of the power supply system is the electric power output mode. As Figure 5 shown, this process may include the following steps:

[0147] Step 501: Obtain the current initial power generation power of the generator module.

[0148] The above-mentioned initial power generation power refers to the power generation power of the generator module before current adjustment.

[0149] In the embodiment of the present application, before determining the target power generation power of the generator module, the control module may first determine the current initial power generation power of the generator module, and on this basis, adjust the initial power generation power to determine the target power generation power of the generator module.

[0150] As an optional implementation method, a current measurement module (such as Figure 1 the second current measurement module 15 shown) and a voltage measurement module (such as Figure 1 the second voltage measurement module 17 shown) may be respectively connected between the control module and the generator module. Based on this, the control module can obtain the current value of the generator module through the current measurement module, and obtain the current voltage value of the generator module through the voltage measurement module, and multiply the above current value and the above voltage value to obtain the current initial power generation power of the generator module.

[0151] Step 502: Determine whether the initial power generation power is greater than the grid power setting value. If so, execute step 503; if not, execute step 504.

[0152] Step 503: Determine the target power generation power of the generator module according to the total load power, the grid power setting value, and the power generation power setting value.

[0153] Step 504: Determine the target power generation power of the generator module according to the initial power generation power and the grid power supply power.

[0154] The following is a unified description of steps 502 to 504:

[0155] The above-mentioned grid power setting value refers to the rated power generation value of the grid module set in advance.

[0156] The above-mentioned power generation power setting value refers to the rated power generation value of the generator module set in advance.

[0157] In the embodiments of the present application, when the power supply mode of the power supply system is in the constant power output mode, there may be a preset grid power setting value for the grid module, and there may be a preset power generation power setting value for the generator module.

[0158] Based on this, after the control module obtains the current initial power generation power of the generator module, it can first determine whether the initial power generation power is greater than the grid power setting value of the grid module.

[0159] Optionally, when it is determined that the above initial power generation power is greater than the grid power setting value, it indicates that the total load power of the power supply system is relatively large at this time, and the power supply power of the generator module is greater than the grid power supply power of the grid module. At this time, the target power generation power of the generator module can be determined according to the above total load power, grid power setting value, and power generation power setting value.

[0160] As an exemplary implementation manner, it can be determined whether the generator module reaches a preset maximum power limit condition. The maximum power limit condition represents the condition when the generator module reaches the maximum power generation power.

[0161] As an implementation manner, when it is determined that the above generator module does not reach the maximum power limit condition, it indicates that there is an adjustment range for the generator module at this time. Therefore, the total load power can be subtracted from the above grid power setting value to obtain the remaining load power (for ease of description, hereinafter referred to as the second remaining load power).

[0162] After that, the maximum power generation power of the generator module can be obtained (specifically, reference can be made to the description in step 401), and the minimum power value can be determined from the above power generation power setting value, maximum power generation power, and the second remaining load power, and the minimum power value can be determined as the target power generation power of the generator module.

[0163] As another implementation manner, when it is determined that the above generator module reaches the above maximum power limit condition, it indicates that the power generation power of the generator module cannot be adjusted further at this time. Therefore, the current initial power generation power of the generator module can be determined as the target power generation power of the generator module.

[0164] Optionally, when it is determined that the above initial power generation power is less than or equal to the above grid power setting value, it indicates that the total load power of the power supply system is relatively small at this time, and the grid power supply power of the grid module is greater than the power supply power of the generator module. At this time, the target power generation power of the generator module can be determined according to the above initial power generation power and grid power supply power.

[0165] As an exemplary embodiment, it can be determined whether the initial power generation is greater than or equal to a preset initial power threshold, and the initial power threshold is less than the grid power setting value. For example, when the grid power setting value is 500 kW, the above initial power threshold can be 200 kW.

[0166] Optionally, when it is determined that the initial power generation is greater than or equal to the initial power threshold, it can be determined whether the grid power supply is less than or equal to the above grid power setting value. If it is determined that the grid power supply is less than or equal to the above grid power setting value, the target power generation of the generator module can be determined as the initial power threshold; if it is determined that the above grid power supply is greater than the grid power setting value, the target power generation of the generator module can be determined as the above grid power setting value.

[0167] For example, assume that the grid power setting value provided by the grid module for the load is 500 Kw (adjustable), and the maximum power generation of the generator module is 4000 Kw (adjustable).

[0168] As an embodiment, when the grid power generation ≤ 500 kW, if 200 kW (initial power threshold) ≤ initial power generation ≤ 500 kw, the target power generation of the generator module can be 200 kW (adjustable in the range of 0 - 200 kW).

[0169] Based on this, when the initial power generation > 500 kW, if the generator module reaches the maximum power limit condition, the target power generation is the current initial power generation; if the generator module does not reach the maximum power limit condition:

[0170] Optionally, when the power generation setting value ≤ total load power - 500 kW, if the power generation setting value ≤ the maximum power generation of 4000 KW, the target power generation is the power generation setting value; if the power generation setting value is greater than the maximum power generation value of the generator module of 4000 Kw, the target power generation is the maximum power generation value of the generator module of 4000 Kw.

[0171] Optionally, when the power generation setting value > total load power - 500 kW, if the power generation setting value ≤ the maximum power generation of 4000 KW, the target power generation = total load power - 500 Kw; if the power generation setting value > the maximum power generation value of 4000 KW > total load power - 500 kW, the target power generation = total load power - 500 Kw; if the power generation setting value > total load power - 500 kW > the maximum power generation of 4000 kW, the target power generation = the maximum power generation of 4000 kW.

[0172] As another implementation, when the grid power generation is > 500 kW, if 200 kW (initial power threshold) ≤ initial power generation ≤ 500 kW, the target power generation = 500 kW (adjustable within the range of 0 - 500 KW).

[0173] Based on this, when the initial power generation > 500 kW, if the generator module reaches the limit condition, the target power generation is the current initial power generation; if the generator module does not reach the maximum power limit condition:

[0174] Optionally, when the set power generation value ≤ total load power - 500 kW, if the set power generation value ≤ the maximum power generation 4000 kW, then the target power generation = the set power generation value; if the set power generation value > the maximum power generation of the unit 4000 kW, then the target power generation = the maximum power generation 4000 kW.

[0175] Optionally, when the set power generation value > total load power - 500 kW, if the set power generation value ≤ the maximum power generation 4000 kW, then the target power generation = total load power - 500 kW; if the set power generation value > the maximum power generation value 4000 kW > total load power - 500 kW, then the target power generation = total load power - 500 Kw; if the set power generation value > total load power - 500 kW > the maximum power generation 4000 kW, then the target power generation = the maximum power generation 4000 kW.

[0176] The technical solution provided by the embodiments of the present application obtains the current initial power generation of the generator module, determines whether the initial power generation is greater than the grid power set value. If so, the target power generation of the generator module is determined according to the total load power, the grid power set value, and the set power generation value; if not, the target power generation of the generator module is determined according to the initial power generation and the grid power supply. This technical solution, when the power supply system operates in a constant power output mode, compares the current initial power generation of the generator module with the pre-set grid power set value of the grid module, and adjusts the initial power generation of the generator module differently according to different comparison results, so as to adjust the power generation of the generator module according to the different proportions of the power provided by the generator module and the grid module for the load, avoiding the situation where the power generation of the generator module is greater than the total load power when the different discharge power ratios of the generator module and the grid module, ensuring the continuous and normal operation of the generator set and improving the economic benefits of users.
