利用纵横向调节改善三相不对称系统电能质量的研究

IMPROVEMENT OF ELECTRIC POWER QUALITY BY USING LONGITUDINAL AND TRANSVERSAL REGULATIONS

以附加注入电流的形式在常规三相潮流算法中计及纵向调节和横向调节的作用，并在此基础上研究得出：纵向调节和横向调节不仅可以调控电力系统的潮流分布，而且也可通过适当调整达到改善电能质量的目的。计算实例表明，该方法可以处理各种纵横向调节以及线路和负荷的各种不对称情况，并由此系统地分析他们对电力系统潮流分布及改善不对称度以提高电能质量的应用效果。

By using injected current.this paper presents a new method for dealing with thelongitudinal and transversal regulations in usual three phase load flow algorithm. and points out:the regulations not only can control the power flow,but also improve quality of electric power.Examples show that the method provides an effective analysis tool for different cases ofregulations,unsymmetrical lines and unbalanced loads of systems.and can improve quality ofelectric power by using regulations.
