Title: Zhenxi Wang: Innovator in High Voltage Direct Current Power Transmission

Introduction

Zhenxi Wang is a notable inventor based in Jiangsu, China. He has made significant contributions to the field of high voltage direct current (HVDC) power transmission. With a total of 2 patents, his work focuses on enhancing the efficiency and reliability of power transmission systems.

Latest Patents

Wang's latest patents include a "High Voltage Direct Current Power Transmission Series Valve Group Control Device." This device is designed to regulate a series circuit that consists of two or more valve groups, each equipped with controllable power semiconductors. The device features a current regulation unit that manages the direct current flowing through its corresponding valve group, while a voltage regulation unit controls the voltage across the valve group. The system designates one valve group as the master control valve group, with the others functioning as slave control valve groups. The master control valve group utilizes a trigger angle output from the current regulation unit to manage its operations, while the slave control valve groups adjust their trigger angles based on inputs from the master control valve group.

Another significant patent is the "Commutation Control Method and Commutation Control Apparatus." This method involves detecting transient disturbances in a DC transmission system and determining a maximum trigger delay angle for commutation operations. The current converter on the inverter side of the DC transmission system is then controlled to perform commutation based on this determined angle, ensuring improved performance during transient conditions.
