The utility model relates to an integrated automation system for a substation, in particular to an advanced and reliable integrated automation system for a high-speed railway unattended substation, which is characterized in that double communication management machines are arranged and are accessed into an in-station local area network together with in-station protection monitors and an in-station monitoring system. As a working mode that the double communication management machines work cocurrently is adopted, the seamless handover of the management machines is really achieved, and the reliability of dispatcher communication is improved; as a more reliable optical fiber Ethernet is adopted as a communication medium, redundance and dynamic flow balance of double nets are realized and the influence of interference and uncertainty factors is reduced; as the in-station monitoring function is weakened, the system overhead is reduced; and as the management machine is directly accessed into a starlike dispatcher ba
