摘　　要：换流站无功平衡对交直流系统的正常运行有着非常重要的影响。德宝直流输电工程是四川和陕西"水火互济"的直流联网工程,优化了两地能源资源配置。根据高压直流输电稳定运行要满足的无功平衡条件,结合交流系统的无功补偿能力,重点分析在不同运行方式下的无功功率消耗和无功补偿装置配置方式,研究德阳换流站分别作为整流站和逆变站运行时的无功平衡,通过计算和数字仿真,验证了德阳换流站的无功补偿容量的正确性和装置配置方案的有效性。Reactive power balance of converter station exerts a profound influence on the normal operation of AC and DC system. Being a DC link project of Sichuan and Shanxi＇s ＂hydro power and thermal power aiding each other＂, Debao HVDC project optimizes allocation of resource and energy in the two provinces. According to the requirements of reactive power balance when HVDC transmission is in stable operation, and combined with reactive power compensation capacity of AC system,this paper mainly analyzes the configurations of reac- tive power compensation devices and reactive power consumption under different operation modes. Also the re- active power balance of Deyang converter station as rectifier station and inverter station respectively are stud- ied. Finally, the correctness of reactive power compensation capacity of Deyang converter station and feasibili- ty of its configuration scheme are verified through calculation and digital simulation.
