| 摘要: |
| 点火脉冲是直流输电系统中换流阀控制的关键技术之一，也是控制保护平台国产化设计的研究重点。描述了用于控制换流阀导通的点火脉冲的产生原理，通过该原理分析了点火脉冲产生过程中频率跟踪器以及相位积分器的主要功能及实现方法。分析了6脉动换流阀点火脉冲等间距的重要性以及如何确保产生的点火脉冲间距误差能够尽可能的小，并针对该设计建立了相应的试验方法。较完整地叙述了换流阀点火脉冲的产生原理及实现方法，对于直流输电控制保护的国产化设计提供了有力的支持。 |

| Abstract: |
| Firing pulse is one of the key technologies of HVDC valves control as well as the research emphasis of domestic control and protection platform. This paper briefly introduces the generating principle of firing pulse used for valve control in HVDC transmission system, based on which the resolution about phase integrator and PLL tracking controller and their functions during the process of the firing pulse generation are analyzed. At last, the significance of equidistance pulses in 6 pulses system is analyzed, as well as how to minimize the equidistance error. This paper gives corresponding testing methods based on the design. Combining theory with practice, this paper describes the generation principle of firing pulse and the realization method, which provides a strong support for realizing home-made production for HVDC control and protection system. |
