摘要
针对江苏电网现状,考虑利用宜兴抽水蓄能水电站作为黑启动电源,启动龙政直流参与初期黑启动可加快电网恢复速度。通过对直流参与黑启动时的控制模式、启动方式、解锁方式及顺序控制的研究,确定了黑启动时直流自身的技术要求。同时针对直流以最小功率启动的情况,研究了黑启动时的交流系统强度要求、励磁涌流抑制和无功协调配合。利用PSCAD电磁暂态模型进行仿真,结果验证了理论分析的正确性。
In order to speed up the power grid recovery,Yixing pumped storage power station can be used as a black-start power source according to the present situation of Jiangsu Power Grid to start Long-Zheng HVDC at the initial stage of black-start. The control modes,startup modes,de-blocking methods and sequential control of HVDC for involving in the black-start are researched to set its technical conditions needed. For the HVDC startup with the minimum power,the technical requirements of AC system,inrush current depression and reactive power coordination are researched. The results of simulation with PSCAD electromagnetic transient model verify the correctness of theoretical analysis.
