摘要
对智能变电站二次系统通信过程进行模拟,即IEC 61850采样值报文和GOOSE报文进行捕获和发送,实现智能变电站故障录波仿真;在此基础上,采用连续复小波变换的波形分析算法提取基波向量,克服了系统频率波动对故障特征量计算的影响,进而模拟保护动作行为和重合闸过程,为智能变电站二次系统的原理和操作的研究及培训提供技术手段.
Based on the communication simulation of intelligent substation secondary system, this paper realized the simulation of intelligent substation fault recorder function, including the trans- ceiving of IEC 61850 and GOOSE. This paper also adopted the Continuous Complex-wavelet Transform algorithm to extract the fundamental phasor, in order to overcome the system fre- quency fluctuation effect to the fault features calculation, and simulated the protection action and reclosing process, which provided technical means for the research of principals and training oper- ation in the intelligent substation secondary system.
