Latest Patents
Hongming Mei holds a patent for a "Suppression method of high-frequency resonance for VSC-HVDC system based on nonlinear filter in voltage feed-forward control." This invention utilizes a nonlinear filter for the voltage feed-forward link in the current inner loop control. The method involves extracting each sequence component of the AC voltage, calculating the average value at N sample points, and comparing it with the previous output of the nonlinear filter. The result is a fixed value that varies according to gradient, effectively suppressing high-frequency resonance without compromising the system's rapidity. This invention also allows for adjustments during AC voltage disturbances, reducing the risk of over-current in the converter valve. Notably, it can be implemented in existing secondary control software without the need for new equipment, making it a cost-effective solution.
