摘　　要：阐述了新型换流变压器及配套滤波装置的接线方案和滤波器设计特点,在此基础上建立了以初期投资最小为目标函数的滤波装置数学优化模型,在采用遗传算法对优化模型进行优化设计时,考虑到优化模型的特点,采用了混合罚函数法将有约束问题转化成带有罚项的无约束问题的目标函数。最后针对具体的新型高压直流输电平台模型给出了滤波装置优化设计的实例,算例结果验证了该优化设计的正确性。This paper introduced the connection plan of the new type converter transformer and filter as well as the design characteristic of the filter. The filter＇s mathematical optimization model taken the minimum investment as target function was created. This paper adopted the mixed penalty function method changing the restraint problem to the object function with penalty without restraint, when using the genetic algorithm to optimize the model and considering the characteristic of the model. At last, aiming at the specific new type HVDC＇s platform, an example of the optimization of filter was given. The results of the example prove correction of the optimization design.
