逆变站无功控制及无功补偿设备的投切策略

Reactive Power Control and the Strategy of Reactive Power Compensation Equipment for Switching on the Inverter Station

无功控制是高压直流输电控制保护的重要功能,也是确保电网安全稳定运行的重要手段。在介绍无功功率控制对换流器作用的基础上,叙述了枫泾换流站无功功率控制的功能和投运后的无功补偿设备的投切策略,并且结合无功控制系统的运行策略,提出了治理现场运行有关交流电压偏高、避雷器泄漏电流超标和电容器故障的措施和改进建议。

Reactive power control is an important function in high voltage DC transmission control and protection, and is the important factor to ensure the power grid safe and stable. Based on the introduction of the effect that the reactive power control has for inverter operation, this article describes the function of the reactive control and the strategy of reactive power compensation equipment for switching at Fengjing Station after operating strategy, and puts forward the measures and suggestions to manage operation accidents.
