| 摘要: |
| 提出将高压悬浮取能工作电源结合电源管理机制来为配网系统一体化设备供能。该工作电源采用高压悬浮双边取能，保证了一体化设备核心模块合并单元能在全相、非全相运行时可靠工作。在分压电容后端串联补偿电抗器和添设过电压保护电路来消除负荷波动影响和解决过电压防护问题。电源管理模块通过对高压取能模块与后备电源的管理控制，实现二者的配合工作，为高压侧有源设备提供稳定可靠的电源。最后给出了电源控制模块的唤醒机制逻辑设计和备用电源选型及容量设计。 |

| Abstract: |
| It is proposed to combine the suspended power supply at high-voltage side with the power management mechanism in the supply of energy for the integrated devices of intelligent distribution network. The suspended power supply at high-voltage side imbibes energy from two sources to ensure the reliable operation of merging unit of the core module of integrated devices，in both complete and incomplete phase modes. A compensating reactor is connected in series with the voltage-dividing capacitor to eliminate the influence of load fluctuation and the over-voltage protection circuit is configured. The power management unit coordinates the operations of suspended power supply and backup power supply to support the reliable and stable power supply for the active devices at high-voltage side. The logic of power awakening mechanism and the type selection and capacity design of backup power supply are given. |
