| 摘要: |
| 在晋北-南京直流工程安稳系统原有功能基础之上，增加了短时内相继发生手动停运和故障跳闸时损失功率识别的方法。在发生连续的功率损失时，安控系统能够准确识别并动作，使得安控系统功能及其控制策略更加完善。详细介绍了南京站接入的华东频率协控系统组成和功能，以及当某条直流线路闭锁出现功率缺额时，频率协控系统应采取的动作策略。通过频率协控装置站系统试验和系统试验，验证了华东频率协控系统及其控制策略的有效性和准确性，并就目前频率协控系统的不足提出了优化建议。 |

| Abstract: |
| On the basis of the security system original function, the Jinbei-Nanjing HVDC project increases a new recognition method of power loss, when sequential manual outage and fault tripping occur in a short time. In the event of continuous power loss, safety control system can accurately identify it and then act, the new control strategy makes the safety control system more perfect. The paper introduces the composition and function of frequency control system of East China in detail, also introduces what action strategy should be taken when the power shortage is caused by the blocking of one of the HVDC lines. The effectiveness and accuracy of the East China frequency coordination control system and its control strategy are verified by the system test, and the optimization suggestions on the shortcomings of current frequency association control system are proposed.
