Improvement of Optimal PMU Placement for Analytical Solution of Power Flow Node by Node
【摘要】 研究了在电网中配置同步相量测量单元(PMU)以实现潮流方程直接可解的方法,提出了动态关联度的概念,在此基础上提出了基于动态关联度配置PMU的静态优化算法和半动态优化算法,并通过算例分析比较了两种方法与已有方法的性能。结果表明,文中提出的方法简单、快捷,较已有方法可有效减少PMU配置数目,适用于稀疏分布的大规模电网。
【Abstract】 A method of placing synchronized phasor measurement units (PMUs) in power network to realize analytical solution of power flow node by node is researched. A concept of dynamic incidence-degree is put forward, and a static optimal algorithm and a semi-dynamic optimal algorithm for PMU placement based on dynamic incidence-degree are proposed. The performances of above-mentioned two algorithms are compared with those of existing methods by case studies. The comparison results demonstrate that the proposed methods are fast and simple, and the amount of placed PMUs by the proposed methods is smaller than that by existing methods, so it is suit to sparse large-scale power network.
