基于半波长输电系统准稳态模型，建立了特高压半波长与直流混联系统，即通过直流线路异步联网的系统间接入半波长输电线路的系统方程，结合直流线路滤波器投切、送受端无功补偿装置等，研究了半波长输电线路两侧端口处系统电压和无功特性，提出了半波长不同送电功率和直流运行功率变化时基于系统的稳态潮流特性的特高压半波长与直流混联系统的送受端联合电压无功控制方案，分析了不同送电功率和负载功率因数情况下半波长输电线路的电压和电流分布特性，以及直流运行功率变化对半波长输电系统潮流电压的影响。

Abstract

An ultra-high voltage(UHV)half-wavelength alternating current(AC)power transmission line connected to the original direct current(DC)asynchronous networking system is built based on the quasi-steady model of UHV half-wavelength. A combined reactive power control scheme is proposed for half-wavelength transmission system with different power supply of half-wavelength and DC power by means of the DC link filter and the power supply terminal reactive power compensation device. In order to improve the power factor at the end of the half-wavelength transmission system

which is based on the voltage and reactive power characteristics of the half-wavelength transmission line on both sides of the half-wavelength transmission line. The steady-state operation characteristics of the system including voltage and current distribution characteristics of the half-wavelength transmission line under different power supply and load power factors are analyzed

as is the influence of the variation of DC operating power on the voltage of the half-wavelength transmission system.
