Application of INVT GD300-01A-EH in high-speed aerator

Project background

In the context of the "3060" carbon peaking and carbon neutrality goals, the national carbon market was officially launched to support green production and low-carbon emission reduction with high-tech products.

In recent years, the development scale of my country's aquaculture industry has continued to grow, and the demand for oxygenation equipment has also increased accordingly. At present, the level of oxygenation machines in the aquaculture industry is generally old and consumes serious power. Further improving the level of oxygenation technology can promote aquaculture. development of the industry and effectively increase breeding output.

Customer requirements
1. High speed

2. Digital intelligent control and display 

3. Free switching of operating modes 

4. Mobile phone remote monitoring 

5. Equipment safety protection function and proactively notify customers in case of failure

INVT Solution

* Advantages of GD300-01A-EH:
1. It has a variety of fault protection functions, including unique phase sequence detection function, hardware phase loss detection function, etc.

2. Built-in dual PID control of pressure and temperature, the control is more intelligent, the wiring is more convenient, and the debugging is simpler.

3. The advanced vector control algorithm optimizes product adaptability while adjusting the best performance output to improve system operation reliability.

Therefore, INVT launches a system solution of GD300-01A-EH series dedicated VFD for high-speed motor + TC series HMI + ICA413-02-CN IOT module. This solution has the advantages of high efficiency, energy saving, and advanced functions.

* Advantages of INVT solution

● High efficiency and energy saving: The synchronous motor flux linkage online observation algorithm has good parameter robustness and adopts the MTPA energy-saving algorithm.
● High control performance: The new generation of synchronous motor vector algorithm operates at high carrier frequency (without reducing the carrier frequency at high speeds), and the current harmonics are within the controllable range.
● Simple to operate: Simple and convenient, high-performance HMI, sensitive touch response, adaptive control program.
● Intelligent cloud platform: The mobile APP can remotely view the device status and operating data without going to the site. When encountering a fault, it can proactively notify and handle it efficiently to improve user experience. Early warning and protection functions can be set up for various harsh application scenarios to reduce the failure rate.

Mobile APP monitoring 

INVT promotes green and low-carbon development with technological innovation and provides more energy-saving and environmentally friendly advanced equipment for all walks of life. At the current stage of aquaculture, INVT improves the overall quality through effective oxygenation technology, promotes the healthy and sustainable development of the aquaculture industry, and achieves the "carbon peaking and carbon neutrality" goals.
