摘要
为了防止融冰装置投运时对其它用户和设备造成影响和危害,测试分析了移动式直流融冰装置对110 kV罗城变电站电能质量的影响。测量结果显示该装置消耗无功功率多、产生特征谐波含量大,造成罗城站110 kV、35 kV、10 kV母线电压总谐波畸变率超标。得出融冰时应切除融冰装置供电母线上所有负荷、电容器组及母线电压互感器的结论。提出了直流融冰装置应该加装5、7次单调谐滤波器的建议。
In order to avoid the influence and damage of DC ice-melting device on other devices after it operation. The influence of movable DC ice-melting device on the power quality in 110 kV Luocheng substation are tested and analyzed. Test results show that the device has more reactive power consumption and larger characteristic harmonic content, which causes over standard of the total harmonic distortion of 110 kV, 35 kV, 10 kV bus. It is concluded that all loads,capacitors,voltage transformers on the same bus with the device should be removed before ice-melting. It is suggested that the 5 and 7 times of single tuned filter should be installed for the DC ice-melting device.
