Power utilization supervision system for high-voltage users of power system

The invention provides a power utilization supervision system for high-voltage users of a power system. The power utilization supervision system comprises a power utilization monitoring terminal, a field information acquisition subsystem and a monitoring host located in a main controller, the power utilization monitoring terminal is installed at the wire inlet end of a transformer on the high-voltage user side, and the monitoring host is in communication connection with the power utilization monitoring terminal to obtain power utilization information of a high-voltage user, compares the power utilization information with the power of a main meter of the high-voltage user and judges whether the high-voltage user has power utilization abnormity or not; and the monitoring host is in communication connection with the field information acquisition subsystem to obtain running state information of the high-voltage user electric equipment, and compares the running state information with standard running state informa
