| 摘要: |
| 目前在高压直流输电工程中，当整流站交流系统较弱而要求无功控制功能选择电压控制模式，或无功控制模式处于手动模式时，直流运行中无功控制功能因未配置系统无功平衡控制功能，导致出现交流系统无功越限或不足的问题。现提出一种直流输电工程中无功控制功能的优化策略，并通过RTDS验证了该优化策略的可行性。该策略在高岭背靠背直流工程中实现了首次应用，在确保无功控制功能为手动模式或电压控制模式的同时消除了系统无功越限或不足的问题，提高了直流系统稳定运行效率。 |

| Abstract: |
| At present, when the reactive power control function in HVDC project is required to select the voltage control mode because of the weaker AC system, or when reactive power control mode is in manual mode and the reactive power control function in DC operation is not equipped with the system reactive power balance control function, the problem of reactive power overstepping or insufficiency in AC system appears. This paper presents an optimization strategy of reactive power control function in HVDC transmission project, and verifies the feasibility of the optimization strategy through RTDS. This strategy has been applied for the first time in Gaolin Back-to-Back HVDC project, eliminating the problem of reactive power exceeding or insufficient while ensuring that the reactive power control function is manual mode or voltage control mode, and improving the stable operation efficiency of DC system.
