摘要:
提出一种新颖的限制电力系统故障电流的桥式电路,对该电路的工作原理、电路结构和工作方式进行了详细的分析,并给出了限流电路中各支路的电流关系,对电路的直通、开路和变阻3种工作方式作出说明,重点分析了在变阻工作模式下,对负载短路电流的限制和分流. 考虑了当桥式限流电路中的开关管栅极加入脉冲信号后,对负载电压和电流的谐波影响,以及限流电感中串入电阻后对开关管占空比的不同要求、对桥式电路分流性能的影响等. 最后给出了部分仿真波形和计算值.
Abstract:
A new kind of bridge type fault current limiter(FCL)which is used in power system has been presented. Detailed analysis has also been made including circuit’s principle,structure and working mode. The relationship of current in the branch of FCL and three types of working mode,that is,conduction without resistance,open circuit,and conduction with resistance,when the FCL in working condition are provided. In the mode of conduction with resistance,shunting effect has been considered which can reduce the fault current flow through the limiting inductance. Considering when IGBT switching works with different duty ratio,the output voltage,current and their harmonic component will also be changed. At end of this paper,part of the simulation and calculate result is given.
