Description

Technical Field

[0001] The present application relates to the field of new energy, and in particular to a control method and device, a storage medium and an electronic device for a typhoon-resistant wind turbine generator set. Background Art

[0002] When a typhoon hits, the power grid is usually out of service, and the wind direction will change over a wide range. If the wind turbine stops yaw, it will be in an extremely unfavorable load-bearing state, and blades and towers may break. In addition, as the power level and impeller diameter of offshore wind turbines continue to increase, the load on the entire machine increases significantly when a typhoon hits and the power is lost. If the wind turbine structure is continuously strengthened to resist typhoons, the cost of the wind turbine will increase significantly. In order to reduce the load at extreme wind speeds during a typhoon, offshore wind turbines are often equipped with diesel generators to power the wind turbine auxiliary system in the event of a power outage, thereby driving the wind turbine yaw system to actively yaw to resist the typhoon.

[0003] Compared with diesel generators, electrochemical energy storage systems have the advantages of fast response, high power conversion efficiency, long life and high reliability. (1) Electrochemical energy storage systems can quickly respond to changes in wind turbine power demand, realize charge and discharge switching within milliseconds, and provide stable power support for wind turbines. When a typhoon causes a power grid failure and the wind turbine needs emergency backup power, the electrochemical energy storage system can be put into use immediately to ensure the normal operation of key wind turbine equipment such as control systems and yaw systems, and improve the wind turbine's typhoon resistance and safety. (2) Electrochemical energy storage systems have a high energy conversion efficiency, generally above 80%, and can efficiently convert stored electrical energy into the electricity required by the wind turbine. The energy conversion efficiency of diesel generators is relatively low, usually around 30% to 40%, and a large amount of energy will be lost in the form of heat energy. This means that under the same energy input, electrochemical energy storage systems can provide more available power for wind turbines, reducing energy consumption and operating costs. (3) With the continuous development of modern electrochemical energy storage technology, the life and reliability of energy storage batteries have been significantly improved. At the same time, the structure of the electrochemical energy storage system is relatively simple, without complex mechanical parts, low operating and maintenance costs, and high reliability. In contrast, diesel generators require regular maintenance, such as changing oil and filters, and are prone to failures in harsh environments, such as fuel supply problems and engine failures. In natural disasters such as typhoons, the reliability of diesel generators may be more challenged, while electrochemical energy storage systems are more adaptable to harsh environmental conditions and provide stable and reliable power guarantees for wind turbines.

[0004] However, compared with diesel generators, the control of electrochemical energy storage systems is more complicated, especially when it comes to the storage on the DC bus side of wind turbines, which involves the coordinated control of multiple terminals of the converter, and the control of wind storage systems is even more complicated. It is necessary to develop a targeted multi-terminal coordinated control strategy based on the unit status, energy storage configuration and architecture, and grid operation status, and cooperate with the wind farm SCADA system to implement the typhoon control strategy for each unit, but the existing technology lacks a system solution for this part.

[0005] With regard to the problem that related technologies lack typhoon-resistant control strategies that utilize electrochemical energy storage systems to accomplish typhoon-resistant control, no effective solution has been proposed so far.

[0036] The following is an introduction to the professional terms that appear in this application:

[0037] Typhoon-resistant wind turbines: refers to wind turbines that can operate stably in strong wind environments such as typhoons and resist typhoon attacks.

[0038] PCC: Point of Common Coupling. For typhoon-resistant wind turbines equipped with energy storage systems, it refers to the common connection point where the converter circuit breaker outlet or the energy storage system circuit breaker outlet is connected to the low-voltage side of the box transformer.

[0039] Energy storage SOC: Indicates the charge and discharge status of the battery, used to describe the ratio of the current battery power to the full battery power.

[0040] In this embodiment, a control method for a typhoon-resistant wind turbine generator system is provided. Figure 2 is a flow chart of a control method for a typhoon-resistant wind turbine generator system according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps S202-S206:

[0041] Step S202: upon receiving a typhoon warning signal, controlling the typhoon-resistant wind turbine generator set to switch to a backup power supply preparation mode, wherein the typhoon warning signal is used to indicate that a typhoon will reach a target area within a first time period, the typhoon-resistant wind turbine generator set is arranged in the target area, and the backup power supply preparation mode is used for the typhoon-resistant wind turbine generator set to charge the energy storage system;

[0042] Step S204: when it is determined that the battery capacity of the energy storage system is greater than the first threshold, controlling the typhoon-resistant wind turbine generator set to switch to a high-wind power generation mode, and stopping charging / discharging the energy storage system;

[0043] It should be noted that the above-mentioned first threshold can be set to 90%. Optionally, the judgment condition for controlling the typhoon-resistant wind turbine to switch to the high-wind power generation mode can also be based on the typhoon entry time. If the typhoon entry time is less than 12 hours, it is also necessary to switch the working mode of the typhoon-resistant wind turbine to the high-wind power generation mode.

[0044] Step S206: When it is determined that the typhoon wind speed is greater than the second threshold, the typhoon-resistant wind turbine generator set is controlled to enter a typhoon-resistant mode, and starts to supply power to the target area through the energy storage system.

[0045] Through the above steps, first, after receiving the typhoon warning signal, the typhoon-resistant wind turbine group is controlled to switch to the backup power supply preparation mode, wherein the typhoon warning signal is used to indicate that the typhoon will reach the target area within a first time period, and the typhoon-resistant wind turbine group is arranged in the target area, and the backup power supply preparation mode is used for the typhoon-resistant wind turbine group to charge the energy storage system; if it is determined that the battery capacity of the energy storage system is greater than the first threshold value, the typhoon-resistant wind turbine group is controlled to switch to the high wind power generation mode, and the charging / discharging of the energy storage system is stopped; if it is determined that the typhoon wind speed is greater than the second threshold value, the typhoon-resistant wind turbine group is controlled to switch to the typhoon resistance mode, and the target area is powered by the energy storage system; by adopting the above scheme, an AC side energy storage control method for typhoon-resistant wind turbine groups is proposed, thereby solving the problem of the lack of typhoon resistance control strategy using electrochemical energy storage systems to complete typhoon resistance control in the related art.

[0046] In an exemplary embodiment, before controlling the typhoon-resistant wind turbine to switch to the high-wind power generation mode, the method further includes: determining whether a current twist cable angle of the typhoon-resistant wind turbine is greater than a pre-cable release angle; when it is determined that the current twist cable angle is greater than the pre-cable release angle, yaw release is performed on the typhoon-resistant wind turbine, and the typhoon-resistant wind turbine is controlled to switch to the high-wind power generation mode; when it is determined that the current twist cable angle is less than or equal to the pre-cable release angle, the typhoon-resistant wind turbine is controlled to switch to the high-wind power generation mode.

[0047] Determine whether the current twist cable angle of the typhoon-resistant wind turbine is greater than the pre-cable release angle (usually set to 360°). If the twist cable angle is greater than the pre-cable release angle, yaw release is performed to release the twist cable angle by 360° to leave a margin for adjusting the yaw angle in the next stage. After the yaw release action is completed, the typhoon-resistant wind turbine enters the high wind power generation mode, and the energy storage system stops charging and discharging.

[0048] Optionally, after controlling the typhoon-resistant wind turbine to enter the typhoon-resistant mode, the method further includes: determining whether the municipal power grid is powered off; if it is determined that the municipal power grid is not powered off, supplying power to the target area through the municipal power grid; if it is determined that the municipal power grid is powered off, starting to supply power to the target area through the energy storage system.

[0050] After controlling the typhoon-resistant wind turbine to enter the typhoon-resistant mode, it is necessary to determine whether the mains power grid has power. If the grid is not cut off, the mains power is used to supply power for the maintenance and auxiliary power of each unit; if the grid is cut off, the typhoon-resistant wind turbine enters the backup power supply start-up mode and uses the energy storage system to supply power to the target area. Disconnect the low-voltage side circuit breaker 103 of the box transformer and the grid-side circuit breaker 301 of the converter. The DC-DC converter of the energy storage system first uses the boost control mode to discharge, so that the converter DC bus voltage rises to the rated value U DC * The converter on the machine side of the converter stops running, and the converter on the grid side adopts the grid-type control mode to generate electricity. ref and Q ref The droop control is used for setting, and the formula is as follows:

[0054] Optionally, after starting to supply power to the target area through the energy storage system, the method further includes: calculating a discharge reference current based on a reference voltage and a measured voltage of a DC bus of a converter of the typhoon-resistant wind turbine group; calculating a discharge modulation voltage based on the discharge reference current and the measured discharge current; and controlling the IGBT module to switch on and off at a second duty cycle through the discharge modulation voltage, so as to control the energy storage system to discharge according to the discharge reference current.

[0055] like Figure 4 As shown, the discharge control process 12- is mainly composed of S2 controlling the conversion switch 12-1, the discharge modulation voltage PI calculation 12-2, and the discharge reference current PI calculation 12-3. When the energy storage system is discharging, S1 controls the conversion switch to switch to off, and S2 controls the conversion switch to switch to the discharge controller. The DC-DC discharges the energy storage battery through the boost conversion mode. First, the DC bus reference voltage and the measured voltage of the typhoon-resistant wind turbine converter are substituted into the PI module to calculate the discharge reference current as follows: Then, the discharge reference current and the measured discharge voltage are substituted into the PI module to calculate the discharge modulation voltage as follows: Finally, the IGBT module T2 is switched on and off at a certain duty cycle (i.e., the second duty cycle mentioned above) through the discharge modulation voltage control, so that the energy storage system can discharge according to the specified reference current and keep the DC bus voltage of the typhoon-resistant wind turbine converter near the reference value.

[0082] Optionally, after controlling the typhoon-resistant wind turbine to enter the typhoon-resistant mode and starting to supply power to the target area through the energy storage system, the method further includes: determining an average yaw error of the typhoon-resistant wind turbine in a second time period; determining whether the average yaw error is greater than a yaw-to-wind threshold; and yawing the typhoon-resistant wind turbine to the wind when the average yaw error is greater than the yaw-to-wind threshold.

[0083] In the anti-typhoon mode, except for the early warning and alarm signals related to personal safety and serious equipment safety, other early warning and alarm signals are shielded. Each unit yaws to the wind in real time and adjusts the unit's upwind or downwind direction to the wind based on the average yaw error within 30 seconds.

[0084] It should be noted that when the 10-minute average wind speed is less than the cut-out wind speed and the SCADA system prompts that a typhoon is passing, the SCADA system activates the unit to enter the recovery detection mode. The detection items mainly include the following aspects: 1) Reset the early warning and alarm signals that are blocked during the typhoon; 2) Check whether the unit status is OK; 3) Check whether the power grid is OK; 4) Check whether the entire wind farm communication network is OK. If all the detection feedbacks are normal, the closing box changes the low-voltage side circuit breaker 103 and the converter grid-side circuit breaker 301, the unit exits the anti-typhoon mode and enters the MPPT grid-following control mode to operate normally in grid-connected operation and power generation, and the energy storage system DC-DC converter adopts the step-down control mode for charging. If one of the tests fails, manual on-site inspection and maintenance must be carried out. After the maintenance is completed, each unit exits the anti-typhoon mode and enters the normal operation state, and the energy storage system DC-DC converter adopts the step-down control mode for charging.

[0085] In an optional embodiment, the typhoon-resistant control strategy of the typhoon-resistant wind turbine generator set is shown in Fig. 9 As shown. When the typhoon arrives at the wind farm 24 hours before, the wind farm SCADA system issues a typhoon warning, the typhoon-resistant wind turbine enters the backup power supply preparation mode, checks the wind farm power grid, communication network, personnel in place, etc., the typhoon-resistant wind turbine operates normally in accordance with the MPPT grid-following control mode, and the energy storage system DC-DC converter is charged in the buck control mode. When the SOC of the energy storage system is greater than 90% or the typhoon entry time is less than 12 hours, it is determined whether the current twist cable angle of the wind turbine is greater than the pre-cable release angle (usually set to 360°). If the twist cable angle is greater than the pre-cable release angle, the yaw cable release is performed, and the twist cable angle is released by 360° to leave a margin for adjusting the yaw angle in the next stage. After the yaw release action is completed, the wind turbine enters the high wind power generation mode, and the energy storage system stops charging and discharging. When a typhoon strikes, the wind speed is greater than the set value (cut-out wind speed) or the typhoon entry time is less than 4 hours, and the typhoon-resistant wind turbine enters the typhoon-resistant mode and shuts down. Determine whether the grid has power. If the grid is not cut off, use the mains power to provide maintenance and auxiliary power for each unit; if the grid is cut off, the typhoon-resistant wind turbine unit enters the backup power supply start-up mode. Disconnect the low-voltage side circuit breaker 103 of the box transformer and the grid-side circuit breaker 301 of the converter. The energy storage system DC-DC converter first uses the boost control mode to discharge, so that the converter DC bus voltage rises to the rated value U DC * The converter on the machine side of the converter stops running, and the converter on the grid side adopts the grid-type control mode to generate electricity. ref and Qref The droop control is used for setting, and the formula is as follows:

[0086] In the typhoon resistance module, except for the early warning and alarm signals related to personal safety and serious equipment safety, other early warning and alarm signals are shielded, and each unit yaws in real time, and adjusts the unit upwind or downwind to the wind according to the average yaw error within 30 seconds. When the 10-minute average wind speed is less than the cut-out wind speed and the SCADA system prompts that the typhoon is passing, the SCADA system activates the unit to enter the recovery detection mode. The detection items mainly include the following aspects: 1) Reset the early warning and alarm signals that are shielded in the typhoon; 2) Check whether the unit status is OK; 3) Check whether the power grid is OK; 4) Check whether the entire wind farm communication network is OK. If all the detection feedbacks are normal, the closing box changes the low-voltage side circuit breaker 103 and the converter grid-side circuit breaker 301, the unit exits the typhoon resistance mode and switches to the MPPT grid-following control mode to connect to the grid and generate electricity normally, and the energy storage system DC-DC converter adopts the step-down control mode for charging. If one of the tests fails, manual on-site inspection and maintenance must be carried out. After the maintenance is completed, each unit will exit the typhoon resistance mode and enter normal operation. The energy storage system DC-DC converter uses the step-down control mode for charging.
