摘要
文章基于交流特高压线路分布参数模型,建立Π型等值电路,分析了不同长度和不同负载情况下单条特高压线路的电压和无功特性,得出了特高压线路的无功需求曲线;并利用PSASP软件用户自定义模型建立了FACTS可控并联补偿潮流模型,通过对一个含特高压线路的四区域系统引入FACTS补偿前后的潮流计算,分析了可控并补参数对特高压系统电压控制的效果。
Equivalent Ⅱ circuit is proposed based on the AC UHV line model with distributed parameters. The voltage distribution and reactive power characteristics along the UHV transmission line with different lengths and loads are studied to obtain the reactive power demand curves. With the user-defined model of PSASP software, and without FACTS devices, and power flow analysis is executed voltage control effect of FACTS on a four-zone power system with devices in AC UHV power systems is analyzed.
