The invention discloses a method, a system and equipment for processing intelligent substation mass network messages. According to the method, two independent circular buffer queues are utilized for managing initial data and compressed data of the intelligent substation mass network messages, data of the messages are acquired, analyzed and stored by means of a producer cursor and a consumer cursor of each queue, and accordingly zero copy of the data is achieved, CPU resource cost caused by copy of mass data is reduced greatly; besides, application of weak coupling strategy of storage and analysis modules prevents the hidden trouble that storage tasks and analysis tasks are quit together due to message exception analysis, and thus message packet loss is avoided. By the method, the system and the equipment, capacity of processing the intelligent substation network messages is improved greatly.
