| 中文摘要 | 采用了一种基于变参数追踪的电力系统暂态仿真算法。该算法将时间维作为微分代数-差 分方程组的一个普通参数来处理,通过预估-校正的计算环节,连续求解得到系统在暂态过程中的 轨迹。从该算法出发,提出了一类状态变量限值和约束函数对控制参数的灵敏度并推导了其公式。 基于该灵敏度,提出了一种暂态稳定预防控制方法。该方法以控制总成本最小为目标,综合考虑多 故障的协调。通过新英格兰10机39节点系统的算例,验证了文中方法的有效性。; A time-domain simulation approach based on parameter-switching tracing (PST) technique is adopted for power system transient stability analysis. With the time-step-size expanded as an unknown variable to be solved, the diffcrential-algebraic-difference equations are solved continuously through two phases of prediction and correction. Based on the PST method, a type of sensitivity from state variables limits and restraint functions to controllable variables is proposed and formulated. Then a sensitivity based preventive control method for transient stability is proposed. The objective in this control method is to minimize the total cost of control and coordination among multiple contingencies is also considered. At last, the PST method and the sensitivity based preventive control method are validated through digital tests on the New England 10-generator 39-bus system.; 国家重点基础研究发展计划资助项目(973项目)(2004CB217904) 国家自然科学基金资助项目(50595414)。~~ |
