摘要
提出了一种快速计算考虑N?1静态安全约束的电力系统最大负荷能力的方法,该方法分为2步:首先确定限制系统N?1静态安全约束下的最大负荷能力的关键支路;然后将关键支路对应的最先作用的有效约束加入潮流方程,利用扩展潮流方程确定实际的最大负荷系数。IEEERTS24节点系统和我国某实际682节点系统的算例分析表明文中所提方法简单、有效、计算速度快。
A new method of quickly calculating maximum loadability of power system considering N-I static security is proposed. This method is divided into tWO steps： at first the key branch which restraints the maximum loadabiltiy of power system under N-1 static security is determined; then the effective constraint corresponding to the key branch, which is the first to functionate, is added in power flow equations and the actual maximum loading coefficient is determined by use of expanded power flow equations. The calculation results from IEEE RTS 24-bus power system and a certain domestic 682-bus power system show that the proposed method is simple and effective and its calculation speed is fast.
