移相器技术是现代电力系统中重要的潮流控制手段之一。随着电力电子控制技术在移相器设计中的应用,其功能已从稳态潮流控制扩展至改善系统稳定性方面。在对国内外移相器技术的发展、应用及研究成果进行调研的基础上,探讨了移相器的工作原理、控制方法、概念设计及应用原则等主要内容,并结合移相器技术的发展、应用现状,对其在超高压电网的应用前景予以了展望。
Phase shifter technology is one of the important power flow control methods in modern power systems. With the application of power electronic control technology in the design of phase shifters, its function has been extended from the steady-state power flow control to improve the system stability. Based on the research on the development, application and research results of phase shifter technology at home and abroad, the main work of the phase shifter is discussed, such as the working principle, control method, concept design and application principle. Combined with the development of phase shifter technology , Application status, prospects of its application in the EHV power grid are prospected.
