| Abstract: | As key technique in HVDC transmission system, control system is extremely important to guarantee the realization of basic control strategy. The influence of DC current reference value on basic control mode in UHVDC transmission system is analyzed. According to recorded fault data during operation of Yunnan-Guangdong UHVDC Project, group block resulted from abnormal switching of basic control mode is analyzed in detail. Some practical measures including DC control system logic modification are proposed to improve system operation condition. It provides valuable reference for future implementation of UHVDC power transmission projects in China. |
