The invention discloses a power grid terminal communication system. The power grid terminal communication system comprises a power utilization terminal, an information acquisition module, a local centralized processor, a GPRS (General Packet Radio Service) module and a remote monitoring center which are connected in sequence, wherein the information acquisition module is used for acquiring the data information of the power utilization terminal, aggregating the data information of the power utilization terminal into the local centralized processor, establishing connection with the GPRS network through a GPRS module, and transmitting the data information to the remote monitoring center; the remote monitoring center is used for analyzing and processing the data information transmitted by the power utilization terminal, and sending a control command back to the corresponding power utilization terminal. By adopting the power grid terminal communication system disclosed by the invention, a high-speed, bidirectional, real-time and integrated power grid communication system can be realized.
