摘要
某10 kV油机系统在现场带载试验过程中,当加载超过额定容量的50%时,出现电压持续波动.通过故障树分析发现,根本原因是非线性负载产生的谐波电流.采取重新整定AVR参数、加装滤波装置的措施,解决了该问题.
During the on-site load test of a 10 kV oil engine system,when the load exceeds 50%of the rated capacity,the voltage fl uctuates continuously.Through fault tree analysis,it is found that the root cause is harmonic current generated by nonlinear load.The problem was solved by readjusting AVR parameters and installing fi lter.
