The invention provides a method for evaluating the service operation reliability of a PTN of the power communication network. The method comprises the following steps: acquiring equipment fault information in a power communication network PTN; determining equipment performance parameters according to the equipment fault information; and performing weighted calculation on the performance parameters by using an intelligent algorithm, comparing a calculation result with a critical value determined in advance according to historical alarm data, and triggering early warning if the calculation result breaks through the critical value. According to the method, the network operation state is evaluated through multiple indexes such as the optical power, the bit error rate and the packet loss rate of the optical modules at the two ends of the transmission medium, early warning is conducted on the equipment nodes touching the network potential safety hazard warning line depending on big data analysis, the purpose of act
