Step S10: and acquiring stator temperature information of the generator.
Acquiring the stator temperature information includes acquiring a stator temperature.
The stator comprises a plurality of stator windings and iron cores, temperature sensors are arranged at the positions of each winding and each iron core, and the temperatures of the plurality of stator windings and the temperatures of the iron cores are not related absolutely, so that the temperatures of the plurality of stator windings and the temperatures of the iron cores can be different, and further, the acquired stator temperature information can be known to comprise the temperatures of the plurality of stator windings and the temperatures of the iron cores.
The stator temperature information can be acquired in a timing manner, the information acquisition frequency is adjusted according to different application scenes or different working requirements, and communication resources are saved and calculation resources are also saved by adopting the timing information acquisition manner.
Optionally, the mode of acquiring the stator temperature information can also be real-time acquisition, the stator temperature information is acquired in real time, and the fan operation is controlled more accurately based on the temperature information acquired in real time.
Step S11: and detecting whether the stator temperature information of the generator meets the temperature preset condition.
The detecting the stator temperature information includes acquiring the stator temperature information of the generator at a fixed time interval T and detecting, or acquiring the stator temperature information of the generator in real time and detecting at the fixed time interval T.
In an alternative embodiment, the stator temperature information of the generator is selected to be acquired in real time, and detected at fixed time intervals T.
Wherein detecting the stator temperature includes detecting an average value of the stator temperature within a fixed time interval T or detecting a maximum value of the stator temperature within the fixed time interval T;
detecting whether the stator temperature information accords with a temperature preset condition or not at each fixed time T, namely detecting whether the stator temperature accords with the temperature preset condition or not at each fixed time T, wherein the temperature preset condition comprises a stator temperature preset threshold value, and the temperature preset condition can be set according to construction safety standards or actual requirements.
Step S12: if the temperature preset condition is met, determining a target fan from the running fans, controlling the target fan to stop running, and controlling at least one standby fan in the fan unit to run.
When the stator temperature information accords with the temperature preset condition, the generator can work normally, and the running fans in the fan unit can ensure that the stator temperature of the generator is in a normal range. However, in order to avoid the reduction of service life of the fan caused by overlong operation time of the fan, when the stator temperature information accords with the preset condition, the embodiment needs to determine the target fan from the operation fans and control the target fan to stop operation, so that long-time operation of the fan is avoided.
Optionally, in the embodiment of the present application, the target fan in the operating fan may be determined by comparing the operating time of the operating fan or the temperatures of the stator winding and the iron core corresponding to the operating point, for example, the operating fan with the longest operating time or the temperature of the stator winding or the iron core corresponding to the operating point may be selected as the target fan.
Because the stator comprises a plurality of stator windings and iron cores, the position of one stator winding and iron core is called a point position, and if an operating fan is arranged on the point position, the point position is called an operating point position.
In this application embodiment, the target fan represents the longer operation fan of operating time, in order to avoid the long-time operation of fan, after confirming the target fan, can control the target fan and stop the operation, and control the target fan and stop the back, in order to avoid the generator heat dissipation untimely, influence the performance, still need control the reserve fan in the fan unit and begin to operate.
The number of the standby fans to be controlled to start to operate may be based on the stator temperature of the generator, and if the difference between the stator temperature of the generator and the preset threshold value of the stator temperature is large, for example, the stator temperature of the generator is 90 ℃, and the preset threshold value of the stator temperature is 100 ℃, the same number of the standby fans as the target fans may be controlled to start to operate. For example, if only one operation fan stops operating, one standby fan is controlled to start operating, and similarly, if two operation fans stop operating, two standby fans are controlled to start operating, and if the difference between the stator temperature of the generator and the preset threshold value of the stator temperature is smaller, for example, the stator temperature of the generator is 100 ℃, the preset threshold value of the stator temperature is 100 ℃, the number of standby fans exceeding the target fan can be controlled to start operating, for example, if only one operation fan stops operating, the two standby fans are controlled to start operating. The above-mentioned determination of larger difference and smaller difference can be set according to actual requirements.
The method for selecting the standby blower comprises the steps of starting the standby blower at a point position with the maximum temperature of the stator winding and the iron core if the blower is not operated at the point position, and starting the standby blower with the nearest point position if the blower is operated at the point position with the maximum temperature of the stator winding and the iron core.
Step S13: and if the temperature preset condition is not met, controlling all the standby fans in the fan unit to run.
When the temperature of the stator of the generator is detected to be not in accordance with the temperature preset condition, the heat dissipation capacity of the running fans in the fan unit is insufficient to be balanced with the heat productivity of the stator, and in order to quickly return the temperature of the stator to the temperature within the temperature preset condition, all the standby fans need to be controlled to run.
When the temperature of the stator of the generator meets preset conditions, the standby fans and the running fans are subjected to round robin, after a period of round robin, in order to reduce the difference of running time of the fans in the fan unit and prolong the service life of the fans to a greater extent, for example, the number of the fans in one fan unit is 6, three are running fans, three are standby fans, the round robin period is set to be one week, the 6 fans are numbered 1#, 2#, 3#, 4#, 5# and 6#, the running fans are 1#, 3# and 5#, the standby fans are 2#, 4# and 6#, and then after one week, 2#, 4# and 6# are taken as the running fans, and 1#, 3# and 5# are taken as the standby fans.
According to the fan control method provided by the embodiment of the invention, whether the stator temperature information of the generator meets the temperature preset condition is detected by acquiring the stator temperature information of the generator, if the temperature preset condition is met, a target fan is determined from the running fans, the target fan is controlled to stop running, at least one standby fan in the fan unit is controlled to run, and if the temperature preset condition is not met, all the standby fans in the fan unit are controlled to run. Therefore, by detecting the temperature information of the stator of the generator and determining the running fan which stops running and the standby fan which starts running based on the detection result, the continuous running time of the fan is reduced, and the running life of the fan is effectively prolonged.
In order to facilitate controlling the operation of the fan and reduce the complexity of the control, the embodiment of the present application provides an operation mode of the fan, and please refer to fig. 3 in combination, before acquiring the temperature information and the operation state information of the stator of the fan operating in the fan unit, steps S20-S22 are further included.
Step S20: determining an operation mode of the fan unit in response to the operation mode selection;
step S21: determining an operation fan and a standby fan in the fan unit according to the operation mode;
step S22: and controlling the running fans in the fan unit to run.
The upper computer comprises a display unit, the display unit can provide a display interface which interacts with a user, the user can select the running mode of the fan based on a selection frame of the display interface, a selection instruction is issued based on a selection result, the intelligent control end responds to the selection instruction of the running mode to obtain the running mode of the fan unit, and the running of the fan is controlled based on the running mode, wherein the running mode comprises a manual running mode and an intelligent running mode.
In a manual operation mode, an instruction can be issued through the upper computer, and the starting and stopping of the fan at the equipment end are controlled through communication interaction with the intelligent control end; the intelligent operation mode can send out instructions through the intelligent control end so as to control the start and stop of the fan; the intelligent operation mode includes an automatic round robin operation mode and a fixed round robin operation mode.
In order to ensure that the control of the fan unit can be realized under various conditions, three specific operation modes are provided in the embodiment.
Under the conditions that the computing capacity of the intelligent control end is sufficient and the power transmitter operates normally, a self-driven wheel circulation operation mode is adopted; the power transmitter is a sensor for acquiring apparent power of the generator.
Under the condition that the intelligent control end has sufficient computing capacity and the power transmitter fails, adopting a fixed round robin operation mode;
under the condition that the intelligent control end is insufficient in computing capacity or the running state of the running fan is abnormal, a manual running mode is adopted.
Based on this, in this embodiment, the step of determining the operation fan and the backup fan in the fan unit according to the operation mode includes:
if the operation mode of the fan unit is the automatic wheel circulation operation mode, acquiring a first operation working condition of the generator and the heat dissipation capacity of a single fan in the fan unit;
determining a first heat generation amount of the generator according to preset first mapping data; the first mapping data comprise a first operation condition of the generator and a heating value corresponding to the first operation condition;
And determining an operation fan and a standby fan in the fan unit based on the first heat generation amount and the heat dissipation amount of the single fan.
Wherein the apparent power is an amount representing the capacity of the ac electrical device, and the square of the apparent power is equal to the square of the active power plus the square of the reactive power. The first operating condition includes apparent power of the generator, terminal voltage of the generator, field current, and power factor. The first map data characterizes a first heat generation amount of the generator corresponding to the generator under a first working condition. The first mapping data may be obtained through a mapping data table of the generator.
The heat dissipation capacity of the fans in the fan unit is determined by the air cooler cooling water inlet temperature of the fans, the air cooler cooling water flow and the air quantity of the fans, so that the first heat generation capacity of the generator and the heat dissipation capacity of the single fans are obtained through the first mapping data of the generator, the number of the fans required when the generator is subjected to heat dissipation can be determined, the running fans are determined, and the quantity of the running fans subtracted from the total quantity of the fans in the fan unit can be understood to be the quantity of the standby fans.
Based on the above, when the operation mode is selected as the automatic circulation operation mode in the intelligent operation mode in response to the operation mode selection, the PLC acquires apparent power of the generator, terminal voltage, exciting current and power factor of the generator, acquires air cooler cooling water inlet temperature of a fan in the fan unit, air cooler cooling water flow and air quantity of the fan, determines first heat generation quantity corresponding to the first operation working condition according to the first mapping data, and determines the quantity of the operation fans according to the first heat generation quantity and the heat dissipation quantity of the fan.
Optionally, in order to ensure the cooling effect, when selecting the running fans, for example, taking 6 fans as an example, 6 fans are sequentially arranged around the stator of the generator, and the numbers of the 6 fans are respectively 1#, 2#, 3#, 4#, 5# and 6#, if three fans are selected as the running fans, three fans with the numbers of 1#, 3#, 5# can be selected as the running fans, or three fans with the numbers of 2#, 4#, 6# can be selected as the running fans, and the selected running fans can be controlled to run, and the fans which are not selected in the fan set can be used as standby fans for round robin.
According to the operation mode, the step of determining the operation fan and the standby fan in the fan unit further comprises the following steps:
if the operation mode of the fan unit is the fixed round robin operation mode, a second operation working condition of the generator and the heat dissipation capacity of a single fan in the fan unit are obtained;
