Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.
Referring to fig. 1, a flowchart of an implementation of a method for controlling a fan of a transformer cabinet according to an embodiment of the present application is shown, where the transformer includes a plurality of secondary windings, and the method is described in detail as follows:
s101: the temperature of each secondary winding in the transformer is obtained.
S102: and selecting the maximum value of the temperatures corresponding to the secondary windings as the actual temperature of the transformer.
S103: and taking the secondary winding corresponding to the actual temperature as a target winding, and acquiring the distance between the target winding and a fan in the transformer cabinet and the carrying capacity of the target winding.
S104: and calculating the target rotating speed of the fan based on the actual temperature and the set temperature of the fan.
S105: and correcting the target rotating speed based on the carrying amount and/or the distance, and controlling the rotating speed of the fan by adopting the corrected target rotating speed.
Specifically, the transformer cabinet comprises at least one fan, the fan is fixed in position, the relative positions of secondary windings of the transformer are fixed, and the temperature sensors are arranged at the secondary windings of the transformer, so that the positions of temperature measuring points at the secondary windings are fixed and similar to the form of space lattice arrangement, a three-dimensional space coordinate system can be established based on a certain point of the transformer, and each temperature measuring point corresponds to one space position.
The execution main body of the fan control method of the transformer cabinet provided by the embodiment can be a fan controller, and as the load conditions of the secondary windings in the transformer are different, the larger the load quantity is, the higher the temperature is; and the distance between each secondary winding and the fan is different, the farther the distance is, the higher the temperature is, so that the temperatures of different temperature measuring points in the transformer cabinet are different. The fan controller acquires the temperatures acquired by the temperature sensors at the secondary windings according to a preset period, selects the maximum value of the temperatures corresponding to all secondary winding temperature measuring points in the current period as the actual temperature of the transformer in the current period, and calculates the target temperature of the current period based on the deviation between the actual temperature of the current period and the set temperature of the fan. After the target temperature is obtained, the embodiment can also correct the target temperature in the current period based on the distance between the target winding and the fan and the carrying capacity of the target winding, so that the operation efficiency of the fan is improved, and the temperature of the highest temperature measuring point in the transformer cabinet is ensured to be quickly reduced below the standard temperature threshold. In addition, as the distances between different fans and each winding are different, the target rotating speed of each fan can obtain the target wind speed corresponding to the fan after the distance between the target winding and the fan and the carrying capacity of the target winding are corrected, namely, different fans are operated at the same actual temperature by adopting different target wind speeds, so that the safe operation of the transformer can be ensured, the problem of high energy consumption caused by the fact that all fans are operated at high rotating speeds due to the fact that the actual temperature of the transformer is too high can be solved, and the energy-saving effect is realized.
The transformer may be a phase shifting transformer, for example.
In one possible implementation, the specific implementation procedure of S104 includes:
and inputting the actual temperature and the set temperature into a fuzzy controller to obtain the target rotating speed.
In this embodiment, the fuzzy controller may be a fuzzy PID controller, and the fan controller subtracts the actual temperature from the set temperature to obtain a temperature deviation, and inputs the temperature deviation into the fuzzy PID controller to obtain the target rotation speed.
The embodiment adopts fuzzy control, and an accurate mathematical model is not needed in the process, so that the limitation of multi-winding temperature control is overcome, and the robustness of fan control is improved.
In one possible implementation, the specific implementation procedure of S104 further includes:
calculating the deviation change rate of the actual temperature and the set temperature according to the actual temperature and the set temperature of the fan;
and inputting the actual temperature, the set temperature and the deviation change speed into a fuzzy controller to obtain the target rotating speed.
In this embodiment, the fan controller subtracts the actual temperature of the current period from the set temperature to obtain the temperature deviation of the current period, obtains a deviation change rate based on the temperature deviation of the current period and the temperature deviations of the previous N periods, and finally inputs the temperature deviation of the current period and the deviation change rate into the fuzzy controller to obtain the target rotation speed. Wherein N is more than or equal to 1.
In one possible implementation, the specific implementation procedure of S105 includes:
determining a first correction factor based on the distance; the first correction coefficient and the distance are positively correlated;
multiplying the first correction coefficient by the target wind speed to obtain a corrected target wind speed.
Specifically, in the early stage experiment process, the distance between each target winding and the fan and the corresponding first correction coefficient are obtained, the distance is taken as an independent variable, the first correction coefficient is taken as an independent variable, and polynomial fitting is carried out, so that a first fitting formula is obtained. The first correction coefficient corresponding to each distance is the minimum correction coefficient which can enable the temperature of the target winding to be reduced below the standard temperature threshold value in the preset time in the experimental process from the plurality of correction coefficients under the selected distance.
In this embodiment, after the distance between the target winding and the fan in the current period is obtained, the distance is input into a first fitting formula, so as to obtain a corresponding first correction coefficient.
In one possible implementation, the specific implementation procedure of S105 further includes:
determining a second correction factor based on the loading; the second correction coefficient is positively correlated with the loading amount;
and multiplying the second correction coefficient by the target wind speed to obtain the corrected target wind speed.
Specifically, in the early-stage experiment process, each winding carrying capacity and a corresponding second correction coefficient are obtained, the carrying capacity is taken as an independent variable, the second correction coefficient is taken as the dependent variable, and polynomial fitting is carried out, so that a second fitting formula is obtained. The second correction coefficient corresponding to each load is the minimum correction coefficient which can enable the temperature of the target winding to be reduced below the standard temperature threshold value in the preset time in the selected multiple correction coefficients under the load in the experimental process.
In this embodiment, after the carrying capacity of the target winding in the current period is obtained, the carrying capacity is input into a second fitting formula, so as to obtain a corresponding second correction coefficient.
In one possible implementation, the specific implementation procedure of S105 may further include:
determining a first correction factor based on the distance; the first correction coefficient and the distance are positively correlated;
determining a second correction factor based on the loading; the second correction coefficient is positively correlated with the loading amount;
multiplying the first correction coefficient and the second correction coefficient by the target wind speed to obtain a corrected target wind speed.
In this embodiment, if the maximum value of the temperatures corresponding to the plurality of secondary windings in the current period includes at least two, that is, the target windings include at least two, the fan controller obtains the distances between the at least two target windings and the fan, and obtains the carrying amounts corresponding to the at least two target windings, respectively. The fan controller calculates a first correction coefficient and a second correction coefficient corresponding to each target winding respectively, calculates the product of the first correction coefficient and the second correction coefficient corresponding to each target winding aiming at each target winding, averages the product of the first correction coefficient and the second correction coefficient corresponding to each target winding to obtain a target correction coefficient, and finally multiplies the target wind speed by the target correction coefficient to obtain the corrected target wind speed.
As can be seen from the foregoing embodiments, in the fan control method for a transformer cabinet provided in the embodiments of the present application, a maximum value in temperatures corresponding to respective secondary windings is selected as an actual temperature of the transformer; then taking a secondary winding corresponding to the actual temperature as a target winding, and acquiring the distance between the target winding and a fan in the transformer cabinet and the carrying capacity of the target winding; calculating a target rotating speed of the fan based on the actual temperature and the set temperature of the fan; finally, correcting the target rotating speed based on the carrying capacity and/or the distance; and controlling the rotating speed of the fan by adopting the corrected target rotating speed. Therefore, the condition that the temperatures of windings are different due to unbalanced load of the transformer is avoided, the problem that the transformer is failed due to overhigh temperature of a certain winding is avoided, the stable operation and the service life of the transformer are ensured, and the operation efficiency of the fan is improved.
