| 摘 要： | 阐述了无功补偿对电力系统稳定、经济运行的作用。无功功率不足会使系统电压及功率因数降低，从而损坏用电设备，严重时会造成电压崩溃，系统瓦解，造成大面积停电的问题。介绍了无功功率消耗设备和补偿设备。指出了要尽量避免发电机降低功率因数运行，同时也防止向远方负载输送无功引起电压和功率损耗，探讨了电压调整和无功补偿的途径。

| Abstract: | The effects of reactive power compensation on the stable and economical operation of electric power system are introduced in this essay.Insufficiency of reactive power will reduce system voltage and power factor,thus,damage the electrical equipment,as well as cause voltage collapse,system collapse and large area blackout.The reactive power expendable equipment and compensation equipment are also introduced here.It points out that the generator's operating in low power factor should be avoided,at the same ti... |
