【摘要】 柔性直流输电系统的换相电感是电网侧与换流器侧进行能量交换的纽带,其取值大小影响着系统的运行行为以及经济性。笔者基于以往换相电感参数设计基础上,从电感参数与系统功率传输、电流快速跟踪以及谐波电流抑制的关系出发进行了电感参数设计。同时利用PSCAD/EMTDC仿真了电感在适用范围内、外两种情况,其对比分析结果验证了该电感设计方法的正确性。更多还原

【Abstract】 The commutation inductance of VSC- HVDC transmission system is the tie to energy exchange between grid side and converter side. Besides,its value affects the running behavior and the economical efficiency of the system. The author,according to the previous parameter design of commutation inductance,designed the inductance parameter from the aspect of power transmission,fast current tracking and harmonic current suppressing.Through the simulation of inductance in and not in the scope of application via PSCAD / EMTDC,the result verifies the correctness of the design method.更多还原
