摘    要:通过仿真实验对葛洲坝-南桥直流输电改造工程的直流系统静态特性进行了校核,基于葛南直流输电系统的参数,描述了在实验室条件下校核直流输电系统静态特性的方法和原理.文中分别将整流侧和逆变侧的静态特性曲线按拐点分为几个部分,对直流系统的稳态运行点在静态特性曲线的不同部分之间移动的过程,即各种控制方式相互转换的过程和原理进行了描述,并针对实验中的三个具体问题,即定功率方式下的系统控制特性曲线、增加电流裕度补偿功能时的控制特性曲线和电流定值小于1pu时的逆变侧控制特性曲线进行了分析和说明.

关 键 词:电力系统  直流输电系统  控制保护  静态特性

Abstract:The static characteristics of DC transmission system in renovation project of HVDC system from Gezhouba to Nanqiao are verified by simulation. Based on the parameters of DC transmission system from Gezhouba to Nanqiao the method and principle of verifying the static characteristics of DC transmission system under the laboratory condition are described. The static characteristic curves at rectifying side and inversion side are divided into several parts by the points of inflexion and the process in which the stable operation point of DC transmission system moves among different parts in the static characteristic curves, i.e., the interconversion process of various control modes among different parts in the static characteristic curves and its principle, is presented. Three problems in the simulation, i.e., the system control characteristic curves under constant power, the system control characteristic curves under the compensation function by increasing the current margin and the control characteristic curves at inversion side when current is less than one per unit, are analyzed and explained.
Keywords:Power system  DC transmission system  Control and protection  Static characteristic
