摘要
讨论光伏并网逆变器在现场可能产生漏电流的模型,并且在该模型下逆变器产生的容性漏电可以通过软件或硬件方案进行优化,包括隔离变压器、低通滤波器等硬件方案与对保护阈值进行偏置或加权计算处理等软件方案.
The potential leakage current model of grid-connected PV inverter in the field is discussed. The capacitive leakage generated by the inverter can be optimized by software or hardware. Hardware solution: isolation transformer and low-pass filter. Software solution: the protection threshold can be biased or weighted.
