摘　　要：针对风洞静压测试容易受到干扰这一问题,以结冰风洞H桥级联大功率变频调速系统为研究对象,利用ANSYSElectronicsDesktop软件探索了变频调速系统电磁兼容“场-路”协同仿真的方法。通过对变频调速系统动力电缆高频参数、输出谐波干扰、线缆串扰和空间辐射干扰建模仿真,得到了系统传导和辐射干扰波形,为解决风洞静压测试受干扰问题提供了方向和数据。通过整改前后的风洞静压测试结果对比,变频器调速系统的干扰得到了有效抑制,保证了静压测试结果达到了精度要求。The field-circuit cooperative simulation method of variable frequency speed control system was explored by ANSYS Electronics Desktop,taking H-bridge cascade large power variable frequency speed control system of icing wind tunnel as reaserch object in view of the static pressure interference problem in wind tunnel.The model of high frequency parameter of motor cables,output harmonic interference,cable crosstalk,and space radiated interference of the variable frequency speed control system were constructed.The system donductive interference and space radiated interference were simulated for providing solution and data to resolve the static pressure interference problem.The interference of variable frequency speed control system was hold-up and the measure result of static pressure fulfilled the accuracy by comparing the rectified result and un-rectified result of the static pressure.
