The invention provides a method and system for identifying a phase sequence error of a metering device, in particular to the field of energy metering management. The method of the invention specifically comprises the following steps of (1) using the master station of the energy metering management system to independently collect the metering equipment data block of the metering equipment for a predetermined number of times; 2 judging whether that phase sequence error of the measurement equipment occur according to the data block; 3 judging whether that phase sequence error event of the metering device occur or not according to whether the metering device phase sequence error occurs. The measurement and management system for electric water, gas and thermal energy, is applicable to the system structure constructed by the system master station, acquisition equipment and metering equipment. The acquisition equipment collects metering equipment data, carries on the data analysis at the system master station and judges the phase sequence error state and the event, and the analysis result can support the energy metering management system operation and maintenance work, thereby improving the work efficiency and enhancing the system operation reliability.
