Solar-based power distribution network load control terminal energy system

The utility model discloses a power distribution network load control terminal energy system based on solar energy, and belongs to the technical field of energy. The energy system comprises a solar cell panel, a rectifier, a storage battery, an inverter, an alternating current contactor, a special transformer load control terminal, a public transformer TTU and an antenna. The solar cell panel is connected with the rectifier through double wires. The rectifier is connected to the positive and negative electrodes of the storage battery; the positive electrode and the negative electrode of the storage battery are connected to the direct-current end of the inverter; the alternating-current end of the inverter is connected to a port I of the alternating-current contactor; a port II of the alternating current contactor is connected to 220V mains supply; and a port III of the alternating current contactor is connected to the special transformer load control terminal and the public transformerTTU. According to the utility model, it is ensured that the public transformer TTU and the special transformer load controller can still maintain power supply after losing commercial power, thereby ensuring that real-time signaling is communicated with a main station, solving all terminal offline problems caused by power loss, and ensuring marketing and production data quality. 本实用新型公开了一种基于太阳能的配电网负荷控制终端能源系统，属于能源技术领域。该能源系统包括太阳能电池板、整流器、蓄电池、逆变器、交流接触器、专变负控终端和公变TTU，以及天线；所述太阳能电池板与整流器通过双导线连接；所述整流器连接至蓄电池的正负极；所述蓄电池的正负极再连接至逆变器的直流端；所述逆变器的交流端连接至交流接触器的端口一；所述交流接触器的端口二连接至220V市电；所述交流接触器的端口三连接至专变负控终端和公变TTU。本实用新型保证公变TTU和专变负控在失去市电以后依然可以保持供电，从而保证实时发信与主站联通，解决所有因失去电造成的终端掉线问题，保证营销和生产数据质量。
