摘要
发展有效的被动式孤岛检测方法,是多机孤岛课题的发展方向之一.用公共耦合点电压、频率、电压电流相位差和电流谐波失真等参数定义了4项指标,基于被动式孤岛检测方法提出了仅包含简单逻辑的决策树分类器模型,并在Matlab/Simulink环境中对两机并联的情形进行仿真.结果表明:因考虑更多系统参数,该方法克服了检测盲区,获得了比电压/频率继电保护更优的检测性能.
The development of the effective passive island detection method is one direction of the multi-parallel inverter island protection projects.This paper defins four indexes,including the parameters of common coupling point voltage,frequency,voltage current phase difference and current harmonic distortion.And based on the passive island detection method,the decision tree classifier model containing simple logic is proposed,and the parallel operation of two machines is simulated in Matlab/Simulink environment.The results show that this method overcomes the detection blind area and has better detection performance than voltage/frequency relay protection because more system parameters are considered.
