摘要
为了适应特高压交直流混合电网在规划、设计、建设、运行等各个阶段实时仿真研究的需要,充分发挥直流输电物理仿真方法真实准确及全数字实时仿真装置可模拟大规模电网且仿真模型可重复利用的特点,采用分布参数线路解耦方法实现了全数字实时仿真装置与物理直流仿真装置的功率连接技术,采用该功率连接技术搭建了简单交直流电网的数模混合仿真模型。直流启动试验和系统故障仿真试验结果均表明,该技术具有较高的仿真精度和实用性,适用于对交直流并列运行电网进行实时仿真研究。
To meet the demands of real-time simulation of UHVAC/UHVDC hybrid power grid in planning, design, construction and operation during various stages and fully bring features of analogue HVDC simulator, such as reliable results, high precision, and features of full-digital real-time simulator, such as ability to simulate large-scale power grid and repeatable use of models, into play, by use of decoupling of transmission line with distributed parameters the power connection technology for full-digital real-time simulator and analogue HVDC simulator is implemented. Using this power connection technology, a digital/analogue hybrid simulator for a simple AC/DC hybrid power grid is set up. Results of DC start-up test and system fault simulation test show that this power connection technology is practicable and possesses higher simulation accuracy, thus it suits to real-time simulation for parallel operaton of AC/DC hybrid poewr grid.
