【摘要】 本文对最新版的EMTDC程序中直流起动与电流控制的不当之处进行了修正;编制了绘图程序;并将该程序移植到VAX-11/780超小型机上。加编了直流电压控制程序;改进了控制参数优化方法。结合三峡工程分析了指令阶跃、交流系统对称与不对称故障时的系统动态性能。更多还原

【Abstract】 In this paper, modifications to some aspects of the EMTDC program are made; a new digital simulation subroutine of dc voltage control is developed; the optimization method of control parameters is improved. Based on the improved EMTDC program, the system performances of the Sanxia HVDC Project under power order step changes and ac faults are analysed.更多还原
