reactance capacity meaning in Chinese

无功功率部分
无效功率

Consumers successively plunged a large number of silicon controlled commuted devices ( such as steel rolling 、 electrized locomotive 、 aluminium electrolysed devices etc ) and smelting devices to improve their produced efficiency or to save energy . on the one hand it is good for consumers , on the other hand it will arouse the fluctuation of voltage and frequency and it will result in the collision of the active and reactance capacity . meanwhile these nonlinear loads bring much harmonic into the electric network which deteriorate the quality of power supply and hazard the online device enormously
用电部门为了提高生产效益、节约能源，在大电网中相继出现了大量的可控硅整流装置（如轧钢、电气化机车、铝加工电解设备等）以及冶炼设备，这些设备的投入使用对节能有一定好处，但给电网造成有、无功冲击，引起电压和频率的波动，同时，这些非线性负荷向电网注入大量谐波，大大恶化了供电系统的电能质量，给用电设备带来了极大的危害。
