Description

The invention relates to the field of automated control systems for electrical equipment, in particular, to methods and systems for automatic adjustment and control of the frequency converter.

Commissioning is one of the most important stages in the operation of complex electrical equipment, in particular, systems that include a frequency converter (variable frequency drive VFD) with a controlled electric motor and are part of complex technological processes. Errors made during commissioning lead to a decrease in the efficiency of electrical equipment, its failure, which ultimately leads to a disruption of the technological process and associated undesirable consequences.

A wide selection of VFDs from different manufacturers requires the user to have high qualifications, relevant knowledge and skills, which to a certain extent limits the possibilities of using a VFD. The availability of specialized software configuration tools significantly reduces the risk of making mistakes and improves the quality of commissioning.

From US patent US8185846B2, a learning unit for setting up and systems of an industrial robot is known. The present invention discloses a setting unit configured such that an operator can optionally change settings for text displayed in a menu area. The teaching unit includes a main menu area, a drop-down menu area, a status area, a general purpose area, and a message area for monitoring and controlling the operation of an industrial robot that operates in a variety of modes, including teaching and operation setting mode. The known method and system requires the use of a dedicated controller.

The learning unit is also configured with the ability to download operating parameters such as operating speed and other operating parameters according to the working conditions of the robot. The robot controller through the communication interface and receives data on the status of the robot. In this way, the training unit and the robot controller interact with each other, so that the working sequence of the robot can be established and the status of the robot can be easily monitored.

The disadvantages of the described system can be attributed to the use of a specialized control unit, the operation of which requires special skills of the operator, the invention also describes the possibility of controlling the parameters, while the described system does not use the experience of earlier parameter setting, which reduces its efficiency.

From the state of the art, adjustment tools are known, proposed by one of the leading manufacturers of VFDs Yaskawa, information about which is available from open sources (date of treatment 06/23/2020):

The known options represent a hardware-software complex for controlling the parameters of the VFD, according to which, on the user's personal computer, the software for controlling the parameters of the connected VFD is pre-installed. Communication with the VFD is carried out via a cable connection or via the Internet. The control is realized in real time by controlling the parameters.

The second of the proposed tools is presented as a mobile application. According to the known method, software is pre-downloaded to the user's device from the Internet, connected to the VFD via a Bluetooth wireless link and real-time control of the VFD with the ability to change and display the system parameters.

The disadvantages of the described solution include the need for the operator to have special knowledge for correct control of the system parameters, the mandatory presence of a previously prepared user device with access to the Internet to obtain the current software version. Also, the disadvantages of the described configuration and management tool include the lack of a proven algorithm for commissioning the selected VFD.

From US patent application US20140309751A1, a controller, a device control system, a computer program, and a computer-readable storage medium are known. The controller includes a user interface, a selection section and a status display section. The user interface includes an image display device and is connected to an external device including a motor drive shaft as a control target. The selection section is configured to display at least one image and is configured to transmit a control command to an external device based on a selection result corresponding to the option image. The status display section is configured to display at least one status image corresponding to the at least one version of the image, and is configured to reflect the status of the external device on the display image.

The disadvantages of the described solution include the need for the operator to have special knowledge for correct control of the system parameters, the mandatory presence of a previously prepared user device with access to the Internet to obtain the current software version. Also, the disadvantages of the described configuration and management tool include the lack of a proven algorithm for commissioning the selected VFD.

Mn), for example, electric motors 6, upon completion of the check, indicate possible shortcomings of the power circuit such as “Commutation error”.

A set of test circuit parameters is formed (Fig. 13), then the VFD system is tested without load and with load (Fig. 14), while the user has access to the recommended system parameters, as well as individual settings. In order to improve the efficiency of testing, VFD systems simulate the system for a given load. The parameters of the emergency protection are set, the option of setting the factory settings is also provided (Fig. 15), after setting up the motor protection, a test of the emergency motor protections is performed based on the specified parameters.

- Formation and archiving of data on system settings (figure 4). Generate a tuning report and save the optimal tuning parameters. In this case, the user, based on his own needs, can generate the content of the customization report of Fig. 16, perform the customization according to the calendar.

The system controls the alternate passage of the configuration steps and, after successful completion of the configuration of all system parameters, allows the user to safely start up the equipment. The described method makes it possible to perform commissioning, as well as control the parameters of complex technological equipment, without having sufficient knowledge and skills in a certain field of technology in a short period of time, while experience and knowledge of the successful configuration of similar or identical systems will be taken into account.
