摘要
针对电力系统电压崩溃问题,该文在负荷临界电压崩溃特性分析基础上,讨论功率型负荷的电力系统临界电压崩溃的潮流计算方法。提出利用交流电路临界电压崩溃的特性,规避崩溃支路,设置等值的柔性节点及柔性等式约束条件处理等措施,构成电力系统负荷临界电压崩溃的柔性节点潮流算法,为大型电力系统工作域的边界分析提供定量计算方法。IEEE5节点算例表明,所提算法是正确有效的。
To the problem of voltage collapse in power system, the load critical voltage collapse power flow （CVCPF） algorithm in power system with power mode load is discussed under the load critical voltage collapse power flow analysis in this paper. Furthermore, the flexible node power flow algorithm for load voltage critical collapse in power system, which provides a quantitative calculation method for operational zone boundary analysis in large scale power system, is created by the procedure which includes using the characteristics of critical collapse power flow of alternating current circuit, evading collapse branch, setting equivalent flexible node, and processing flexible equality constrain condition, etc. The proposed algorithm has been tested and achieved a very good performance on an IEEE 5-bus sample system.
