Description
Technical Field
The present invention relates to a rotating electrical machine operation (in service) support system and a method of configuring the rotating electrical machine operation support system.
Background
The rotating electric machine includes a rotor and a stator. For example, when a wound-rotor induction motor is used as the induction motor, speed control for obtaining good torque characteristics can be realized by adjusting the secondary resistance.
On the other hand, the cage-type induction motor has a simplified structure without requiring a rotor winding. In recent years, the use of a Variable Voltage Variable Frequency (hereinafter, VVVF) power supply has been combined with a VVVF power supply as a driving device, thereby enabling smooth control of speed and the like and achieving cost reduction.
In addition, in the control of the motor, by using vector control instead of voltage/frequency (V/F) constant control, improvement of the response of the induction motor is achieved.

A motor driving device generally includes an inverter device (VVVF power supply) and a control circuit for controlling the inverter device. In order to adjust a constant of a Control circuit, for example, a gain and an integration time of a PI (Proportional Integral Control) section, it is necessary to know characteristics of a motor.
Therefore, a test for grasping the characteristics of the motor to be driven is performed, and information on the motor is obtained by measurement, thereby obtaining a necessary constant. That is, the motor and its driving device are installed at a site where the motor is used, and after a kind of installation test such as a conduction test of a cable is completed, the installation test is performed. Specifically, for example, it is necessary to perform a no-load test, a direct-current application test, an alternating-current application test, and the like in a state where the motor is coupled to the driving device thereof.
In the case where the tester performs the test under such a situation, interference with the operation of another operator in the same area, limitation of the use time of the area, and the like may occur due to the limitation of the surrounding space, noise in the field, and various operations. Further, after the constant measurement, it is necessary to adjust the control constant such as gain and integration time in PI control or the like based on the measurement result, and there are many items to be performed until the final motor is operated.
Here, the operation is a state in which a rotating electrical machine including an electric motor can be appropriately used in a state in which desired characteristics can be exhibited according to specifications set for various purposes of use, and is useful for use. Further, as a general-purpose driving device, there is also a driving device having an automatic adjustment function.
Fig. 7 is a block diagram showing a conventional configuration example of a motor and a driving device thereof. The drive device 10 of the motor 1 includes an inverter device 11, a control device 12, a motor constant measuring device 14, and an automatic adjustment arithmetic circuit 13.
The inverter device 11 supplies ac power to the motor 1. The control device 12 performs, for example, vector control calculation and issues a command signal to the inverter device 11.
The automatic adjustment computing circuit 13 estimates information on characteristics of the motor 1 and the like required for vector control from the current, voltage, rotation speed, and the like of the drive power of the motor 1. The motor constant measuring device 14 directly or indirectly acquires various parameters in the operating state of the motor 1 required for calculation in the automatic adjustment calculating circuit 13 via the transmission unit 15.
Examples of the information on the characteristics of the motor 1 required for vector control include: and circuit constants such as resistance relationships of the respective resistances in the equivalent circuit of the motor and the respective inductances including the leakage inductance, and a magnetic saturation correction coefficient.
Various methods for measuring these circuit constants have been proposed (see patent document 1). In order to measure the circuit constant, a common method is to perform a no-load test, a direct-current voltage pressurization test, an alternating-current voltage pressurization test, or the like, and determine the circuit constant in order.
Therefore, the drive device 10 includes a motor constant measuring device 14 for performing an experiment of the motor 1 to be driven, automatically measuring information on the motor 1, and acquiring a necessary circuit constant, so as to enable automatic adjustment.
In this way, the process of the drive device 10 automatically adjusting the drive device for each motor 1 to be driven requires the drive device 10 to include the motor constant measuring device 14 and the automatic adjustment arithmetic circuit 13, which causes an increase in the product cost and the development cost.
Further, there are motors that are not suitable for application of automatic adjustment depending on the use of the motor or the control method thereof, and cost advantages are not sufficiently exhibited as long as the opportunity of replacement of the drive device or the motor is not frequent.

Hereinafter, a rotating electrical machine operation support system and a rotating electrical machine operation support system configuration method according to an embodiment of the present invention will be described with reference to the drawings. Here, the same or similar portions are denoted by the same reference numerals, and the overlapping description is omitted.
[ 1 st embodiment ]
Fig. 1 is a block diagram showing a configuration of a rotating electric machine operation support system according to embodiment 1. The rotary electric machine operation support system 300 includes a plurality of rotary electric machines 100 and a plurality of drive devices 200.
Each of the plurality of rotating electric machines 100 includes a rotating electric machine body 110 and an information storage medium 120.

The drive device 200 is configured such that the rotating electrical machine information reading device 210 can read the rotating electrical machine information stored in the information storage medium 120 via the communication medium 130 between the information storage medium 120 of the rotating electrical machine 100 to be driven and the rotating electrical machine information reading device 210 of the drive device 200. In the present embodiment, a case where a cage-type induction motor is used as the rotating electric machine body 110 will be described as an example.
Fig. 2 is a circuit diagram showing an equivalent circuit of a cage induction motor as an example of the rotating electric machine according to embodiment 1. Fig. 2 shows an equivalent circuit corresponding to phase 1 among the phases 3.
The stator side, which is the 1 st side of the cage induction motor as the rotating electric machine body 110, receives power supply from the inverter device 250 of the drive device 200. 1 st side by 1 st inductance L 1 1 times resistance r 1 And an excitation inductor L 0 And the like. The secondary side 2, i.e. the rotor side, is formed by a secondary resistor r 2 And 2-time inductance L 2 And (4) forming. When the amount of slip is s, the equivalent resistance on the 2-th side as viewed from the 1-th side is r 2 /s。
Applying voltage V to 1 time winding 1 Flowing a current I1 times 1 . Current I of 1 time 1 Is the excitation reactance (j ω L) 0 ) A magnetic current I flowing in the middle and generated by the main magnetic flux Phid 0 With torque divided by current I 1 The vector sum of'. Torque divided current I 1 ' cage on the 2 nd side (rotor side) by induction produces 2 times the current I 2 . Current I at 2 times 2 And the main flux phi d is orthogonal to each other to generate torque.
Current I at 1 time 1 The magnetic flux divides the current I 0 Torque split current I 1 ' rotate at 1 frequency. The cage on the secondary side 2 rotates relatively delayed by the slip amount s with respect to the primary side 1, so that the torque partial flux Φ q cuts the conductor of the cage on the secondary side 2, and a current I is generated on the secondary side 2 2 . This is the load current, which is proportional to the load torque.
The 1 st order inductance L shown here 1 1 times resistance r 1 Excitation inductance L 0 And 2 times resistance r 2 The value of each element of the equivalent circuit, that is, the circuit constant of the rotating electric machine body 110This is part of the rotating electrical machine information.
A speed sensor 261 whose output information is used for switching between 2-phase and 3-phase, etc. is provided on the rotor of the rotating electric machine body 110, but in the sensorless vector control, the speed sensor 261 is not provided, and thus the information is estimated information about the rotating electric machine body 110.
The information storage medium 120 of the rotating electric machine 100 stores rotating electric machine information about the rotating electric machine main body 110. As the rotating electrical machine information, there are characteristic values relating to the characteristics of the rotating electrical machine body 110, such as the aforementioned circuit constants, magnetic saturation correction coefficients, and the like of the equivalent circuit of the rotating electrical machine body 110. They are obtained directly or indirectly based on results measured in detail at the factory or test site. When shipping from a factory or a test site to a local place (installation/use place of the rotating electric machine), the rotating electric machine information is stored in the information storage medium 120.
The rotating electrical machine information reading device 210 of the drive device 200 reads and stores the rotating electrical machine information stored in the information storage medium 120 of the rotating electrical machine 100 connected to each other as a drive target, to obtain the rotating electrical machine information. The rotating electrical machine information reading device 210 may access the information storage medium 120 via the communication medium 130 and read the information. Alternatively, the rotating electrical machine information may be transmitted or transferred to the rotating electrical machine information reading device 210 via the communication medium 130, and the rotating electrical machine information may be received by the rotating electrical machine information reading device 210.
The timing at which the rotating electrical machine information reading device 210 can read the rotating electrical machine information may be a point in time when the driving device 200 and the rotating electrical machine 100 receive the supply of electric power from the power supply, respectively. Alternatively, the time point may be before. For example, the rotating electrical machine information reading device 210 is configured to receive power supply from the power supply of the drive device 200 and also independently receive power supply. In addition, the information storage medium 120 is similarly configured to receive power supply from the power supply of the rotating electric machine 100 and also to independently receive power supply. In this case, the rotating electrical machine information reading device 210 can read the rotating electrical machine information stored in the information storage medium 120 as soon as possible.
The method of transmission or transfer, including the communication medium 130, may be based on either wired or wireless.
The control constant setting unit 220 sets each constant used in the control device 230 based on the rotating electrical machine information read by the rotating electrical machine information reading device 210.
The control constant setting unit 220 may be configured to set the constants of the control devices corresponding to the rotating electric machine body 110, for example, a cage-type induction motor or a winding-type induction motor, according to the type of the rotating electric machine body. Further, under the condition that state variables other than the equivalent circuit constant, such as the magnetic flux density, the frequency, and the temperature of the main body, are also included, the optimal constant of the control device may be obtained in advance, and the control constant setting unit 220 may have a built-in list of these state variables as parameters, for example. The control constant setting unit 220 may have a function of performing interpolation or extrapolation calculation between these lists according to the values of the parameters. By providing such a function, the accuracy (japanese: faithful execution degree) of the rotating electric machine control module can be improved, and further improvement in responsiveness and control accuracy can be achieved.

For the portions corresponding to the respective parallel arrangements in series with the rectifier section 251 which is a dc power supply, 2 IGBTs 252a are connected in series, and a diode 252b is provided in parallel with each IGBT252 a. The wiring portions between the 2 IGBTs 252a arranged in series with the respective corresponding portions are connected to the respective phases on the stator side of the rotating electric machine body 110.
Each IGBT252a operates in response to a command signal from the control device 230 with respect to the timing of the switching operation.
Fig. 4 is a circuit diagram showing an example of a configuration of a control device of a drive device in the rotary electric machine operation support system according to embodiment 1. The control device 230 of the drive device 200 is a configuration of a generally used control system that performs vector control.
The control device 230 has: a control part related to driving torque, a control part related to magnetic field setting, a vector control part and a feedback part.
The drive torque-related control section has: a speed setting unit 231, a subtraction unit 232, a speed control unit 233, and a q-axis current control unit 234. The subtraction unit 232 subtracts a speed signal, which is a feedback signal, from the speed sensor 261 from the target speed value set by the speed setting unit 231, and outputs a speed deviation signal. The speed control unit 233 outputs a torque reference for eliminating the speed deviation signal. The q-axis current control section 234 outputs a torque sub-current command i based on the torque reference 1 ’ ＊ 。
On the other hand, the portion related to the magnetic field setting includes a magnetic flux setting unit 235 and a d-axis current control unit 236. The magnetic flux setting unit 235 sets a target value of magnetic flux necessary for forming a magnetic field. The d-axis current control unit 236 calculates and outputs a flux partial current command i based on the target magnetic flux value set by the magnetic flux setting unit 235 0 ＊ 。
The 2-phase converter 239 receives a feedback signal from the current transformer 262 for detecting each phase current of the 3-phase current supplied to the rotating electric machine body 110, sets a rotating coordinate system based on a speed signal as a feedback signal from the speed sensor 261, and sets a rotating coordinate system based on the rotating coordinate systemThe 3-phase current is converted into 2-phase current by rotating the coordinate system. That is, the actual 3-phase currents iu, iv, and iw are converted into torque split currents I 1 ' sum flux partial current I 0 。
The vector controller 237 divides the torque from the q-axis current controller 234 into the current commands i 1 ’ ＊ And a flux current command i from the d-axis current control unit 236 0 ＊ As input, a composite command current i is calculated 1 ＊ Magnitude of (d), phase angle θ.

The above is the configuration and operation of the control device 230, and the inverter device 250 operates based on a command from the control device 230.
Fig. 5 is a flowchart showing steps of a method of configuring the rotating electric machine operation support system according to embodiment 1.
First, the rotating electrical machine information on each rotating electrical machine body 110 is acquired (step S01). The rotating electrical machine information is sequentially obtained directly or indirectly by a no-load test, a dc voltage application test, an ac voltage application test, or the like. Regarding acquisition of the rotating electrical machine information, for the rotating electrical machine main bodies 110 designed and manufactured with the same specification, information with a small individual difference in experience may be used as a result of a load test or the like which has been performed on the spot by another rotating electrical machine main body 110 in the past.
Next, the acquired rotating electrical machine information is stored in the information storage medium 120 of the rotating electrical machine 100 (step S02).
Next, the rotating electric machine 100 and the driving device 200 for driving the same are installed at the site where they are used (step S03). In this case, the system including the rotating electric machine 100 and the driving device 200 may not be in a usable stage. For example, at least the information storage medium 120 of the rotating electrical machine 100 and the rotating electrical machine information reading device 210 of the drive device 200 may be in a state in which the rotating electrical machine information stored in the information storage medium 120 can be transmitted and received.
If the rotating electrical machine information stored in the information storage medium 120 can be transmitted and received between the information storage medium 120 of the rotating electrical machine 100 and the rotating electrical machine information reading device 210 of the drive device 200, the rotating electrical machine information reading device 210 reads the rotating electrical machine information stored in the information storage medium 120 (step S04).
Next, the control constant setting unit 220 of the drive device 200 sets the control constant of the control device 230 based on the rotating electrical machine information read by the rotating electrical machine information reading device 210 (step S05).
As a result, under the control of the control device 230, the supply of electric power to the rotating electric machine main body 110 by the inverter device 250 and the appropriate operation of the rotating electric machine main body 110 become possible (step S06).
The rotary electric machine operation support system 300 according to embodiment 1 configured as described above has the following effects.
1. Since the combination adjustment of the driving device 200 and the rotating electric machine 100 is easy, the time required for the combination adjustment is significantly shortened. Further, the time for acquiring the rotating electrical machine information becomes earlier than before, and thus a sufficient confirmation and adjustment period can be ensured.
2. In the field, a test for grasping the characteristics of the rotating electric machine 100 in which the driving device 200 and the rotating electric machine main body 110 are combined is not necessary, and therefore, the necessity of the field adjustment by the adjuster becomes small, and the field adjustment becomes unnecessary in some cases.
3. Since the rotating electrical machine information reading device 210 incorporates logic for checking the integrity between the pieces of information in the rotating electrical machine information, it is possible to determine that the rotating electrical machine information is erroneous or the like when the rotating electrical machine information reading device 210 reads the rotating electrical machine information.
4. The auto-adjustment function becomes unnecessary, and therefore the product cost or development cost becomes unnecessary, with a cost advantage.
5. Further improvement in response and control accuracy can be achieved by setting control constants very finely using state variables other than equivalent circuit constants, such as magnetic flux density, frequency, and temperature of the main body, as parameters.
As described above, according to embodiment 1, the rotating electric machine can be operated appropriately with a simplified configuration.

In addition, the information storage medium 120 stores information on the rotating electrical machine information, but unlike embodiment 1, only identification information for identifying (japanese: identical) the rotating electrical machine information, such as a reference number or a name, is stored instead of the rotating electrical machine information itself. The other points are the same as those of embodiment 1.
The common server database 140 stores the rotating electrical machine information in a form corresponding to each piece of identification information.
In embodiment 2, the rotating electrical machine information reading device 210 reads the identification information stored in the information storage medium 120 via the communication medium 130. The rotating electrical machine information reading device 210 accesses the shared server database 140 via the communication medium 130 based on the identification information read from the information storage medium 120, and reads the rotating electrical machine information corresponding to the identification information, thereby acquiring the rotating electrical machine information.
In embodiment 2, the drive devices 200 share the common server database 140. This configuration enables various test data to be sequentially integrated in the common server database 140, and is suitable for an environment in which the stored rotating electrical machine information is corrected or adapted according to further operation experience, and the like, and the data is prepared and made high-level. Further, the enrichment of the rotating electrical machine data stored in the common server database 140 is performed in common to all the drive devices 200, and the capital investment effect is sufficient.
In the case of the rotating electrical machine information of the rotating electrical machine 100 which is mass-produced for each model, even if the change is necessary, the data stored in the information storage medium 120 of all the rotating electrical machines 100 does not need to be changed, and the change is limited to the data which is shared by the server database 140, and the correction range based on the data change is the minimum.
