| 摘要: |
| 设置补偿电容器是补偿电网中无功功率的传统方法之一，无功补偿装置在电网中应用相当普遍。而低压电网的无功补偿装置与高压电网的无功补偿装置相比，无论在性能上、技术上都远不如高电网无功补偿装置，并且补偿效果较差。针对以上情况研制的新型低压无功补偿装置电路设计简单、成本低、控制精确且可靠性高。该装置利用新型集成电路器件，通过检测电网中无功电流的大小，并依据电网中电压的高、低控制补偿电容的投切，是一种较理想的低压电网无功补偿装置。 |

| Abstract: |
| One of the traditional methods of reactive power compensation is to use compensating capacitors,therefore, compensation device is widely used in power network.Compared with that in HV network, the reactive power compensation device in low voltage power network is not satisfying either in performance or in technology,its compensating effect is not good enough.A new type of low voltage reactive power compensation device is introduced, which is simple in design,low in cost and high in control reliability and precision. It adopts new type integrated components to check the reactive current of power network and control the switching of capacitors according to voltage level.It is an ideal low voltage reactive power compensation device. |
