Matching Optimization of Power System Reclosing and Emergency Control Based on DSR

文中以能源互联网为研究背景,以电力控制系统为研究目标,基于DSR的量化分析,分别对最优重合闸和最优紧急控制进行研究。按照故障类型的不同选择最佳组合的控制策略。通过选择安全性和经济性最佳的紧急控制方案,利用波形叠加原理,将重合闸失败的二次冲击叠加在紧急控制作用后的系统中,使重合冲击有利于最大功角差的快递收敛,并使系统快速恢复稳定状态。文中还分别就对称和非对称性故障的算例进行比对研究,数据验证了最优重合闸紧急控制匹配优化算法的有效性和实用性。该算法有利于实现电力系统控制网络与其他互联网络的可靠互联,达成整个能源生态系统的良性发展。

Based on the quantification analysis of DSR, to take the energy internet as the research background and the power control system as the research object, the paper studies the optimal reelosing and emergency control re- spectively. According to different fault types to choose the best combination of control strategy, through selecting the best security and economic emergency control program, using the principle of wave superposition, the two im- pulse of the reclosing failure is superimposed on the system after emergency control, and to make the coincidence impact in favor of the convergence of the maximum angle difference and make the system quickly restore stable state. In this paper, a comparison study is carried out on the case of symmetric and asymmetric faults, and the da- ta verified the validity and practicability of the method of matching optimization of power system reclosing and e- mergency control based on DSR. Algorithm is conducive to the reliable interconnection of the power system control network and other interconnected network, and to achieve the healthy development of the entire energy ecosystem.
