摘　　要：利用Matlab/Simulink模块建立高压直流(HVDC)输电的换流变压器分接头控制(TCC)系统,通过对一个交直流混合输电系统进行稳态运行、功率提升及直流短路故障3种情况下的仿真计算,分析系统的稳定性和换流变压器分接头调节的具体过程。分析结果表明,换流变压器分接头控制可以有效地将整流侧触发角和逆变侧熄弧角限制在规定的运行范围内,从而让系统始终处于最佳运行状态。分析还验证了所建模型的正确性。Tap change control system of HVDC was built based on SimPowerSystems in Matlab. The researches on the simulation of HVAC/DC hybrid transmission systems were carried on three situations such as steady state, DC power improving and DC fault. By analyzing the stability of the system and regulatory progress of TCC, the triggered angle at rectifier side and extinction angle at inverter side can be limited in specified operation range by TCC, and let the system always operate the best state. The analysis proved the correctness of the model.
