摘要:
大规模电网输电线路的关键性支路的辨识是输电系统快速处理连锁故障乃至全网崩溃故 障的关键。为此,本文提出了一种基于功率传输分布因子和支路暂态稳定性函数的电网关键线路 综合辨识方法。首先,从电网网络结构的角度,采用功率传输分布因子函数量化输电网络中每一条 支路的关键性;其次,从电网动态运行的角度采用支路暂态稳定性函数,求解各个支路的暂态势能 稳定性来评估各支路的脆弱度。最后,综合两种评估方法构建电网线路关键性综合性评估函数科 学量化每条输电线路在全网功率传输中的作用,并在IEEE39 节点系统中仿真验证了该综合性评估 方法的有效性。
Abstract:
Anidentificationofthekeybranchforlarge?scalepowertransmissionlineisthekeytodealwiththe interlocking fault and the whole network breakdown fault quickly. For this reason,a kind of comprehensive identification method of the key transmission lines of power grid based on power transmission distribution factor and branch transient stability function is proposed. Firstly,from the point of view of power network structure,the power transmission distribution factor function is used to quantify the key events of each branch in transmission power network. Secondly,from the point of view of dynamic operation of power network,thetransientstabilityfunctionofthebranchisadoptedtosolvethetransientpotentialenergystability of each branch with purpose of evaluating the fragility of each branch of power network. Finally,the two evaluation methods are combined to construct the critical comprehensive evaluation function of power grid lines so to scientifically quantify the role of each transmission line in the whole power transmission network. The effectiveness of the comprehensive evaluation method is simulated and verified in the IEEE 39 node system.
