【摘要】：现有电网恢复研究中将快速切回(FCB)机组加入电网串行恢复序列,未充分利用FCB机组能够独立恢复周边电源和负荷的能力。与传统的黑启动水电机组相比,火电机组的FCB功能不能100%成功实施,含FCB机组的电网恢复需要根据黑启动电源情况动态分区。因此,文中在传统GN分裂算法的基础上,提出了适用于含FCB机组电网的分区恢复策略。首先,采用网络的Laplace矩阵特征值识别分区数量,同时考虑了电网分区中黑启动电源要求、功率平衡要求,以及分区划分的速度要求,建立基于改进GN分裂算法的电网分区方法,实现含FCB机组电网的快速自动分区。最后,新英格兰系统和部分江苏电网实际系统仿真结果表明,所提分区方法能够有效地对电网进行动态分区。
[Abstract]:In the current research of power network restoration, the fast cut back FCBs are added to the serial restoration sequence of the power grid, and the ability of FCB unit to recover the peripheral power and load independently is not fully utilized.Compared with the traditional black start hydropower unit, the FCB function of the thermal power unit can not be implemented successfully, and the restoration of the power network containing the FCB unit needs to be dynamically partitioned according to the condition of the black start power supply.Therefore, on the basis of the traditional GN-splitting algorithm, this paper proposes a regional recovery strategy suitable for the power network with FCB.Firstly, the Laplace matrix eigenvalue of the network is used to identify the number of partitions. At the same time, considering the requirements of black-start power supply, power balance and the speed of partition, a power partition method based on the improved GN-splitting algorithm is established.Realize the fast automatic partition of the power network with FCB unit.Finally, the simulation results of New England system and part of Jiangsu Power Grid show that the proposed partition method can effectively partition the power grid dynamically.
