    摘 要:定向过流继电器(DOCRs)的最佳协调在多回路电力系统的保护中至关重要。提出了一种鲸鱼优化算法(WOA),并将 WOA 应用于多回路电力系统中,以实现 DOCRs 的最优协调。DOCRs 协调问题基本上是一个高度约束的优化问题,通过 WOA 求解有约束和无约束优化问题,定义新的目标函数,并使用整定时间系数和抽头整定值上的边界作为变量的限制,将中继协调问题转换为无约束优化问题进行求解。在三、六、九总线的 3 个测试系统中采用 WOA 进行了仿真。结果表明,WOA 的收敛速度较快,能够在较少的迭代次数内获得最优解,实现了继电协调的运行时间最小化,是一种有效可靠的 DOCRs 协调工具。

    Abstract: Optimal coordination of directional over current relays (DOCRs) is crucial in the protection of multi-loop power systems. A whale optimization algorithm (WOA) is proposed and applied to multi-loop power systems to achieve optimal coordination of DOCRs.The coordination problem of DOCRs is inherently a highly constrained optimization problem. This study addresses both constrained and unconstrained optimization via the WOA by defining a novel objective function and transforming relay coordination into an unconstrained optimization problem, using boundaries of time dial setting (TDS) and plug setting (PS) as variable constraints. Simulations were carried out using WOA in three test systems of 3, 6 and 9 buses. The results show that WOA converges faster, can obtain the optimal solution in fewer iterations, achieves the minimization of the runtime of relay coordination, and is an effective and reliable coordination tool for directional overcurrent relays.
    Key words: directional over current relays; multi-loop system; whale optimization algorithm; relay coordination
