The invention relates to a control and protection system measurement abnormity identification method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: acquiring measurement parameters of the system obtained by measuring the direct-current ice melting system; determining a comparison reference value according to the measurement parameters of the system; judging whether the measurement parameters of the system conform to parameter abnormal conditions or not; the parameter abnormal condition is determined according to the comparison reference value; if the measurement parameters of the system meet the parameter abnormal conditions, determining that the main system is abnormal in measurement; and switching the standby system as a main system. By adopting the method, the control protection equipment with abnormal measurement can be identified, the standby system is switched in time to serve as the main system to control the
