Introduction
Jiacheng Wang is a notable inventor based in Jiangsu, China, recognized for his contributions to the field of DC transmission systems. With a total of 3 patents, his work focuses on enhancing the efficiency and reliability of power transmission technologies.
Latest Patents
One of his latest patents is a "Converter control method and device." This invention pertains to an island converter overload limit method and device for a bipolar flexible DC transmission system. It employs a voltage-frequency droop control strategy during stable island operation. When one converter is detected to be overloaded, the control mode switches automatically to active-wattless power control, effectively preventing overloads and maintaining stable AC voltage and frequency. This method is significant for applying island systems to DC power grids.
Another important patent is the "Control system and control method for parallel converter system." This invention includes a common AC voltage controller and separate current controllers for each converter. The AC voltage controller generates active current, wattless current, and a system voltage phase reference value, which are communicated to each converter's current controller. This system ensures the synchronization of multiple converters, enhancing the reliability of the parallel converter system.
