摘　　要：基于降阶雅可比矩阵的多馈入相互作用因子的解析计算方法,分析了直流系统控制方式对多馈入交直流系统换流母线间电压相互作用的影响机理,指出换流站功率对电压的灵敏度是影响电压相互作用强度的重要因素之一。给出了逆变站在不同控制方式下的功率对电压的灵敏度计算公式,通过算例研究了控制方式对逆变站间电压相互作用的影响程度。Using the analytic calculation method from the multi-infeed interaction index and based on the reduced-order Jacobian matrix, the influence mechanism of control mode with respect to the converter bus voltage interaction in a multi-infeed AC-DC system is analyzed. It is shown that the power-voltage sensitivity of the inverter is one of the main factors influencing the voltage interaction strength. The equations of power-voltage sensitivity under different control modes are given. The impact of control modes on voltage interaction between inverters is analyzed by the test system.
