摘要
现有继电保护整定优化方法需要进行多次试验和调整,耗费大量时间和资源,对于大规模分布式新能源系统是非常不可行的.利用离散花授粉算法,对分布式新能源继电保护整定优化进行研究.以时间整定系数和启动电流为优化参数,构建了目标函数.采用离散花授粉算法对其进行优化求解.实验结果表明:设计方法在不到15次迭代下即可获得最优解,且耗时始终保持在60s之内,能够快速且准确的计算出继电保护的整定结果.
Abstract
The existing optimization methods for relay protection setting require multiple experiments and adjust-ments,which consume a lot of time and resources,and are very infeasible for large-scale distributed new energy sys-tems.In this regard,this article uses the dispersed flower pollination algorithm to study the optimization of distribu-ted new energy relay protection settings.The objective function was constructed with time setting coefficient and starting current as optimization parameters.Using the dispersed flower pollination algorithm to optimize and solve it.The experimental results show that the design method can obtain the optimal solution in less than 15 iterations,and the time consumption remains within 60 seconds,which can quickly and accurately calculate the setting results of the relay protection.
