摘　　要：传统连续潮流模型中节点类型为PQ,PV和Vθ这3种。但是,当计算研究远程电压控制模式下系统的电压稳定负荷裕度时,需要引入PQV和P等新的节点类型。文中提出了一种节点类型扩展连续潮流模型,用于求解远程电压控制模式下的静态电压稳定临界点,给出了新的节点类型双向转换逻辑、静态电压稳定临界点类型识别方法。IEEE 39节点系统的仿真算例结果表明,所述模型和方法能够有效地模拟远程电压控制模式的特性,准确计算该控制模式下的系统电压稳定临界点,并准确识别分岔点类型。There are three bus types of the continuation power flow model, namely, PV, PQ and VO. When the voltage stability margins of the power system with remote voltage control are calculated, new bus types, which are PQV and P, are added. A bus-type extended continuation power flow model is proposed. A method is presented for computing the voltage stability critical point and identifying the type of bifurcation in one-to-one or multi-to-one modes. The switching logic of the new bus type is also discussed. Simulation results of IEEE 39 bus system show that the proposed model and method are effective in simulating the feature of remote voltage control and computing the voltage stability critical point as well as identifying the type of bifurcation.
