Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment control, and in particular to an SVG device automatic control method, system, device and storage medium. BACKGROUND

[0002] The static var generator is referred to as SVG, which functions to regulate the phase and amplitude of the output voltage of the bridge circuit through the reactor or directly parallel to the grid, or directly control the current on the AC side, so that the circuit absorbs or emits the required reactive power to achieve dynamic reactive power compensation. According to the grid connection standard, when the sending line of the booster station is electrified, that is, the active power of the sending line is greater than 0, the SVG device needs to be put into operation; and when the active power of the sending line of the booster station is less than or equal to 0, the SVG device does not need to be put into operation. In order to reduce the comprehensive plant power consumption and save production cost, when the active power of the sending line is less than or equal to 0, the SVG device of the plant station stops running.

[0003] The control mode of the SVG device in the related art is manual control, which is to have the on-duty personnel constantly pay attention to the active power of the sending line, manually stop the SVG device when the active power is less than or equal to 0, and start the SVG device as soon as the active power of the sending line is greater than 0. If the SVG device is not started in time when the active power is greater than 0, the examination power will be generated, and if the SVG device is not stopped in time when the active power is less than or equal to 0, the additional power consumption of the SVG device will be increased. SUMMARY

[0004] The present application provides an SVG device automatic control method, system, device and storage medium to solve the problem of the generation of examination power or the increase of additional power consumption caused by the manual control of the SVG device disclosed in the related art.

[0005] In a first aspect, the present application provides an SVG device automatic control method, which comprises: determining whether a first condition or a second condition is met based on the collected active power of the sending line, the active power consumed by the SVG device, the ultra-short-term power reporting point, the number of grid-connected wind turbines and the running state of the SVG device; stopping the SVG device if the first condition is met, and starting the SVG device if the second condition is met; The first condition comprises that the active power of the sending line is less than or equal to 0, the sum of the active power of the sending line and the active power consumed by the SVG device is less than or equal to 0, the predicted power of the ultra-short-term power reporting point is less than or equal to a preset power value, the number of grid-connected wind turbines is less than or equal to a preset value, and the SVG device is running. The second condition comprises that the active power of the sending line is greater than 0 and the SVG device is stopped.

[0006] Through the above-mentioned embodiments, the operation state of the SVG device is started or stopped by using the collected active power of the outgoing line, the SVG device consumed active power, the ultra-short-term predicted power reporting point, the number of grid-connected wind turbines and the operation state of the SVG device. Since the SVG device will consume the active power of the outgoing line during operation, when the collected active power of the outgoing line is less than or equal to 0 and the sum of the active power of the outgoing line and the SVG device consumed active power is less than or equal to 0, it indicates that even if the SVG device is shut down, the active power output by the outgoing line is still less than or equal to 0. By stopping the SVG device, the increase of additional power consumption can be reduced, and at the same time, when the active power of the outgoing line is greater than 0, the SVG device is started to achieve the purpose of reducing the generation of examination power.

[0007] In an optional embodiment, the first condition is determined based on the collected active power of the outgoing line, the SVG device consumed active power, the ultra-short-term predicted power reporting point, the number of grid-connected wind turbines and the operation state of the SVG device, and the first condition includes: The first branch condition is determined based on the collected active power of the outgoing line and the operation state of the SVG device. If the first branch condition is met, the SVG device is stopped based on the SVG device consumed active power, the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines. The first branch condition includes that the active power of the outgoing line is less than or equal to 0 and the SVG device is running.

[0008] Through the above-mentioned embodiments, since the SVG device will consume the active power of the outgoing line during operation, if the SVG device is directly stopped, there is a probability that the active power of the outgoing line will immediately be greater than 0, so further judgment is needed for the stopping of the SVG device.

[0009] In an optional embodiment, the SVG device is stopped based on the SVG device consumed active power, the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines, and the stopping of the SVG device includes: The second branch condition is determined based on the SVG device consumed active power and the active power of the outgoing line. If the second branch condition is met, the SVG device is stopped based on the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines. The second branch condition includes that the sum of the active power of the outgoing line and the SVG device consumed active power is less than or equal to 0.

[0010] By the above-mentioned embodiments, when the SVG device active power consumption and the outgoing line active power meet the second branch condition, the ultra-short-term prediction power reporting point is used to predict the future short-time prediction power of the current wind farm, and when the future short-time prediction power of the current wind farm is greater than the preset power value, stopping the SVG device will cause the SVG device to start in a short time, and frequent start-stop will affect the service life of the SVG device, therefore, whether to stop the SVG device is further judged by using the ultra-short-term prediction power reporting point and the number of grid-connected wind turbines.

[0011] In an optional embodiment, the judging whether to stop the SVG device based on the ultra-short-term prediction power reporting point and the number of grid-connected wind turbines comprises: judging whether to meet a third branch condition based on the ultra-short-term prediction power reporting point; if the third branch condition is met, judging whether to stop the SVG device based on the number of grid-connected wind turbines; the third branch condition comprises that the prediction power of the ultra-short-term prediction power reporting point is less than or equal to a preset power value.

[0012] By the above-mentioned embodiments, when the prediction power of the ultra-short-term prediction power reporting point is less than or equal to a preset power value, the number of grid-connected wind turbines will affect the active power output by the current power plant, and when the number of grid-connected wind turbines is large, the probability of the active power generated by the wind turbine increasing in a short time is large, and the probability of the outgoing line active power being greater than 0 in a short time is large, therefore, the number of grid-connected wind turbines is used to judge when the prediction power of the ultra-short-term prediction power reporting point is less than or equal to a preset power value.

[0013] In an optional embodiment, the judging whether to stop the SVG device based on the number of grid-connected wind turbines comprises: judging whether to meet a fourth branch condition based on the number of grid-connected wind turbines; if the fourth branch condition is met, stopping the SVG device; the fourth branch condition comprises that the number of grid-connected wind turbines is less than or equal to a preset value.

[0014] By the above-mentioned embodiments, when the number of grid-connected wind turbines is less than or equal to a preset value, it indicates that the probability of the outgoing line active power of the current power plant increasing in a short time is low, and under this condition, by stopping the SVG device, the power loss caused by the continuous operation of the SVG device can be effectively reduced, and the probability of the service life of the SVG device being reduced due to frequent start-stop in a short time can also be reduced.

[0015] In an optional embodiment, the ultra-short-term prediction power reporting point comprises a 15min prediction power reporting point and a 30min prediction power reporting point. The third branch condition is satisfied when the predicted power of the 15min predicted power reporting point is less than or equal to a first preset power value and the predicted power of the 30min predicted power reporting point is less than or equal to a second preset power value. The third branch condition is satisfied when the predicted power of the 15min predicted power reporting point is less than or equal to a first preset power value and the predicted power of the 30min predicted power reporting point is less than or equal to a second preset power value. The third branch condition is satisfied when the predicted power of the 15min predicted power reporting point is less than or equal to a first preset power value and the predicted power of the 30min predicted power reporting point is less than or equal to a second preset power value.

[0016] In the above embodiment, the 15min predicted power reporting point obtains the predicted power in the next 15min, and the 30min predicted power reporting point obtains the predicted power in the next 15min to 30min. When the predicted power of the 15min predicted power reporting point is less than or equal to a first preset power value and the predicted power of the 30min predicted power reporting point is less than or equal to a second preset power value, it indicates that the probability of the active power of the outgoing line of the power plant being greater than 0 in a short time is small. Therefore, it is determined that the third branch condition is satisfied.

[0017] In an optional embodiment, the starting of the SVG device comprises: Starting the SVG device after a preset time delay.

[0018] In the above embodiment, the SVG device is started after a preset time delay, so as to avoid the situation that the SVG device is started and stopped in a short time when the active power of the outgoing line suddenly changes to a positive number and then drops to a non-positive number and remains non-positive for a long time, and effectively reduce the situation that the SVG device is frequently started and stopped due to the sudden change of the active power of the outgoing line.

[0019] In a second aspect, the present application provides an SVG device automatic control system, which comprises: A data judging module, configured to judge whether a first condition or a second condition is satisfied based on the collected active power of the outgoing line, the active power consumed by the SVG device, the ultra-short-term predicted power reporting point, the number of grid-connected wind turbines and the running state of the SVG device.

The first condition comprises that the active power of the outgoing line is less than or equal to 0, the sum of the active power of the outgoing line and the active power consumed by the SVG device is less than or equal to 0, the predicted power of the ultra-short-term predicted power reporting point is less than or equal to a preset power value, the number of grid-connected wind turbines is less than or equal to a preset value, and the SVG device is running. The second condition comprises: the sending line active power is greater than 0 and the SVG device is shutdown.

[0031] The embodiment of the present application provides an SVG device automatic control method, which starts or stops the operation state of the SVG device by using the collected active power of a sending-out line, the consumed active power of the SVG device, a short-term prediction power reporting point, the number of grid-connected wind turbines and the operation state of the SVG device; since the SVG device consumes the active power of the sending-out line during operation, when the collected active power of the sending-out line is less than or equal to 0 and the sum of the active power of the sending-out line and the consumed active power of the SVG device is less than or equal to 0, it is indicated that the active power output by the sending-out line is still less than or equal to 0 even if the SVG device is stopped, and the increase of the additional power consumption can be reduced by stopping the SVG device, and meanwhile, the SVG device is started when the active power of the sending-out line is greater than 0, so that the purpose of reducing the generated examination power is achieved.

[0032] According to the embodiment of the present application, an SVG device automatic control method is provided, and it should be noted that the steps shown in the flowchart can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] In the embodiment, an SVG device automatic control method is provided, which can be used in the wind farm terminal device, Figure 2 is a flowchart of the SVG device automatic control method according to the embodiment of the present application, as Figure 2 shown, the flowchart includes the following steps: S201, based on the collected active power of the sending-out line, the consumed active power of the SVG device, the short-term prediction power reporting point, the number of grid-connected wind turbines and the operation state of the SVG device, whether the first condition or the second condition is met is judged.

[0034] The active power of the sending-out line is the active power of the 110kV sending-out line of the operator station, which is used to represent the active power output by the current station to the power grid; the consumed active power of the SVG device is the consumed active power during the operation of the SVG device of the operator station, the short-term prediction power reporting point is the short-term prediction power generated by the wind power prediction system, and the number of grid-connected wind turbines is obtained by the SCADA (Supervisory Control and Data Acquisition, computer remote supervision control and data acquisition system) in the wind farm station, which is used to represent the number of units in the station that transmit power to the power grid.

[0035] S2021, the first condition is met, and the SVG device is stopped; The first condition comprises: the outgoing line active power is less than or equal to 0, the sum of the outgoing line active power and the SVG device consumed active power is less than or equal to 0, the predicted power of the ultra-short-term prediction power reporting point is less than or equal to a preset power value, the number of grid-connected wind turbines is less than or equal to a preset value, and the SVG device is running.

[0036] When the first condition is met, it indicates that the outgoing line active power in the current station is a non-positive number, and the SVG device consumed active power in the station is greater than or equal to the active power generated by the wind turbine in the station. The probability of the wind turbine generating power increasing in the short term is small, and the probability of the outgoing line active power increasing is also small. By stopping the running SVG device, the probability of the additional power consumption caused by the SVG device in the station can be reduced.

[0037] S2022, the second condition is met, and the SVG device is started; The second condition comprises: the outgoing line active power is greater than 0 and the SVG device is stopped.

[0038] When the second condition is met, it indicates that the outgoing line active power in the station is greater than 0. By starting the stopped SVG device, the reactive power can be easily supplemented to the grid, the dynamic reactive power compensation to the grid can be realized, and the probability of generating the assessment power can be reduced.

[0039] For example, starting the SVG device can be implemented as: starting the SVG device after delaying for a preset time.

[0040] The preset time can be set as a constant, and is determined according to the sudden change of the outgoing line active power in the station. The SVG device is started after delaying for the preset time, so as to avoid the situation that the outgoing line active power suddenly changes to a positive number, and then decreases to a non-positive number after a few seconds, and remains a non-positive number for a long time, resulting in the SVG device being started and stopped for a short time.

[0041] The SVG device is started after delaying for the preset time, so as to avoid the situation that the outgoing line active power suddenly changes to a positive number for a short time, and then decreases to a non-positive number and remains a non-positive number for a long time, resulting in the SVG device being started and stopped for a short time. The situation that the SVG device is frequently started and stopped due to the sudden change of the outgoing line active power is effectively reduced.

[0042] The automatic control method for SVG devices provided in this embodiment utilizes the collected active power of the transmission line, the active power consumed by the SVG device, the ultra-short-term predicted power reporting point, the number of grid-connected wind turbines, and the operating status of the SVG device to start or stop the SVG device. Since the SVG device consumes the active power of the transmission line during operation, when the collected active power of the transmission line is less than or equal to 0, and the sum of the active power of the transmission line and the active power consumed by the SVG device is less than or equal to 0, it indicates that even if the SVG device is shut down, the active power output by the transmission line is still less than or equal to 0. Shutting down the SVG device can reduce the increase in additional power consumption. At the same time, when the active power of the transmission line is greater than 0, the SVG device is started to reduce the amount of power required for assessment.

[0043] This embodiment provides an automatic control method for SVG devices, which can be used in the aforementioned wind farm terminal equipment. Figure 3 This is a flowchart of an automatic control method for an SVG device according to an embodiment of the present invention, such as... Figure 3 As shown, Figure 3 In this diagram, P1 represents the active power of the transmitting line; P2 represents the predicted power at the 15-minute predicted power reporting point; P3 represents the predicted power at the 30-minute predicted power reporting point; P4 represents the active power consumed by the SVG equipment; M represents the number of grid-connected wind turbines; α represents the first preset power value; β represents the second preset power value; and γ represents the preset value for grid-connected wind turbines. The process includes the following steps: S301, based on the collected active power of the transmission line, the active power consumed by the SVG equipment, the ultra-short-term predicted power reporting point, the number of grid-connected wind turbines, and the operating status of the SVG equipment, determine whether the first condition is met.

[0044] S302, if the first condition is met, shut down the SVG device.

[0045] Specifically, S301 above includes: S3011, Based on the collected active power of the outgoing line and the operating status of the SVG equipment, determine whether the first branch condition is met; S3012, if the first branch condition is met, based on the active power consumed by the SVG device, the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines, determine whether to shut down the SVG device; The first branch condition includes that the active power of the transmission line is less than or equal to 0 and the SVG equipment is running.

[0046] The first branch condition is used to determine whether the current SVG device meets the shutdown condition. Since the SVG device needs to consume active power during operation, the SVG device shutdown will result in a decrease in the active power consumption of the wind farm device, and the active power of the transmission line is the difference between the active power generated by the wind turbine in the station and the active power consumed by the SVG device and other devices in the wind farm. When the SVG device consumes less active power, the active power of the transmission line will increase, and the probability of the active power of the transmission line immediately being greater than 0 exists.

[0047] Therefore, even if the active power of the transmission line is less than or equal to 0 and the SVG device is operating, it is still necessary to further determine whether the SVG device is shut down. If the first branch condition is not met, the operating state of the SVG device is maintained, and the SVG device is not shut down.

[0048] Optionally, when the first branch condition is met, whether to shut down the SVG device is determined based on the active power consumed by the SVG device, the ultra-short-term predicted power reporting point, and the number of grid-connected wind turbines, including: Whether the second branch condition is met is determined based on the active power consumed by the SVG device and the active power of the transmission line. If the second branch condition is met, whether to shut down the SVG device is determined based on the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines. The second branch condition includes that the sum of the active power of the transmission line and the active power consumed by the SVG device is less than or equal to 0.

[0049] The second branch condition is used to determine whether the active power of the transmission line will immediately become greater than 0 after the SVG device is shut down and no longer consumes the active power of the transmission line. If the active power of the transmission line immediately becomes greater than 0 after the SVG device is shut down, shutting down the SVG device will result in the SVG device being started again in a short time, which will affect the service life of the SVG device.

[0050] When the active power consumed by the SVG device and the active power of the transmission line meet the second branch condition, the ultra-short-term predicted power reporting point is used to predict the predicted power of the current wind farm in a short time in the future, and when the predicted power of the current wind farm in a short time in the future is greater than a preset power value, shutting down the SVG device will result in the SVG device being started in a short time. Frequent start-stop will affect the service life of the SVG device, so the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines are further used to determine whether the SVG device is shut down.

[0051] Optionally, when the second branch condition is met, whether to shut down the SVG device is determined based on the ultra-short-term predicted power reporting point and the number of grid-connected wind turbines, including: Whether the third branch condition is met is determined based on the ultra-short-term predicted power reporting point. If the third branch condition is met, it is judged whether to shut down the SVG device based on the number of grid-connected wind turbines. The third branch condition includes that the predicted power of the ultra-short-term predicted power reporting point is less than or equal to a preset power value.

[0052] Illustratively, the ultra-short-term predicted power reporting point includes a 15min predicted power reporting point and a 30min predicted power reporting point. The judgment of whether the third branch condition is met based on the ultra-short-term predicted power reporting point includes: Based on the 15min predicted power reporting point and the 30min predicted power reporting point, it is judged whether the predicted power of the 15min predicted power reporting point is less than or equal to a first preset power value and whether the predicted power of the 30min predicted power reporting point is less than or equal to a second preset power value. If the predicted power of the 15min predicted power reporting point is less than or equal to the first preset power value and the predicted power of the 30min predicted power reporting point is less than or equal to the second preset power value, the third branch condition is met.

[0053] The third branch condition is used to judge the active power generated by wind turbines within the next 30min of the wind power prediction system, wherein the time relationship between the predicted power of the 15min predicted power reporting point and the active power of the sending line is less than or equal to the next 15min, and the time relationship between the predicted power of the 30min predicted power reporting point and the active power of the sending line is greater than 15min and less than or equal to 30min.

[0054] The active power generated by the wind turbines predicted by the 15min predicted power reporting point and the 30min predicted power reporting point is judged using the first preset power value and the second preset power value, so as to obtain the probability that the prediction result of the active power of the sending line within the next 30min is greater than 0. When the prediction result of the active power of the sending line within the next 30min is greater than 0, i.e., the third branch condition is not met, in order to avoid frequent start and stop of the SVG device, the SVG device does not perform the shutdown operation at this time and remains in the running state.

[0055] Optionally, when the third branch condition is met, the judgment of whether to shut down the SVG device based on the number of grid-connected wind turbines includes: Based on the number of grid-connected wind turbines, it is judged whether the fourth branch condition is met. If the fourth branch condition is met, the SVG device is shut down. The fourth branch condition includes that the number of grid-connected wind turbines is less than or equal to a preset value.

[0056] The number of grid-connected wind turbines affects the active power of the sending line, and the more grid-connected wind turbines, the higher the probability that the active power generated by the wind turbines increases in a short time, that is, the probability that the active power of the sending line is greater than 0 in a short time is large. The fourth branch condition is used for judgment. In order to avoid the frequent start and stop of the SVG device, the SVG device is not stopped, and the SVG device is kept in the running state. Otherwise, the SVG device is stopped to reduce the probability of generating additional power consumption.

[0057] Optionally, the SVG device automatic control method provided by the embodiment of the application further comprises: When the automatic available hours of the SVG device are low, the SVG device automatic control method is stopped, and the running state of the SVG device is maintained. When the automatic available hours are high, the SVG device automatic control method is used to control the SVG device in the station.

[0058] In the embodiment, an SVG device automatic control system is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and will not be described again. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function.

The second condition comprises that the active power of the sending line is greater than 0 and the SVG device is stopped.

[0060] In some optional embodiments, the data judgment module 410 comprises: A first branch judgment unit 4101 is configured to judge whether the first branch condition is met based on the collected active power of the sending line and the running state of the SVG device. If the first branch condition is met, whether to shut down the SVG device is determined based on SVG device active power consumption, ultra-short-term predicted power reporting point, and number of grid-connected wind turbines. The first branch condition includes that the active power of the outgoing line is less than or equal to 0 and the SVG device is running.

[0061] In some optional embodiments, the data determination module 410 further includes: A second branch determination unit 4102 configured to determine whether a second branch condition is met based on the SVG device active power consumption and the active power of the outgoing line.
